Car audio consulting two
A: My Passat B5 present a plane without a CD, card, or a facelift to install CD, hope the panel is pure black, I do not know whether to recommend a style from the price, are the appropriate vehicle power CD?
A: The original Passat B5 cars can control plane 6-disc CD drive can be installed Panasonic 6-disc drive, but to use the special conversion cable. Dress black panel host, and now the market brand Kenwood, VDO Di Tang and other middle and high-end models mostly silver and gold. But the choice of car audio can not select only the appearance, but also choose their favorite sound. From the cost to the style, are the appropriate vehicle power CD, I believe that the choice VDO Di Tang is characterized by:
① The machine is a European style, suitable for European models, no wiring changes can be directly connected with the car line.
② The machine is a digital model, from radio, tape and CD are digitally processed sound clean and clear. Of course the Japanese middle, Kenwood is also a good choice.
B: I recently a SONY CDX-3500 does not read the dispatch, E-04 appear the words, how to solve?
A: CDX-3500 is a single-disc SONY CD player, single CD with a period of time can cause this problem, display the words E-04 There are several possibilities:
① laser surface contamination, needs cleaning.
② CCD mounted anti-record, you can have the word side up.
③ CCD record dirty, should clean the CDP Lu film.
④ need to adjust the laser head circuit.
⑤ laser head is damaged.

speaker is a kind of energy into the sound of a conversion device,
When the different electron energy spread coil, the coil produces a magnetic field energy and magnetic interaction,
This interaction causes the tray vibration, because the electron energy change at any time,
Speaker of the coil will move forward or backward movement, so the speaker will follow the movement tray,
This action makes this the density of air changes have produced the sound.
Share DIY car audio capacitor with the Need
amplifier audio equipment in the field, a large aluminum electrolytic capacitors may account for almost most of the volume inside. Because each CV plot of aluminum electrolytic capacitors (C: capacitance, V: voltage) than other types of capacitors, their share of the smallest, and because they are cheap (for the capacitance per unit), it is a regular need to be used in large-capacity filter capacitors such as power, energy storage capacitors and other circuit.
Electrolytic capacitor is formed by electrolytic oxidation method and made into a film as a capacitor dielectric. The high-purity aluminum electrolytic capacitors is when the anode, and ethylene glycol, glycerol, boron, and ammonia, and so the composition of the paste as the electrolyte in the electrolyte in the electrolytic surface layer of the aluminum pole thin aluminum oxide film as a medium made into the capacitor. Electrolytic capacitor because the dielectric film can be very thin, so you can make a small capacity of the capacitor, the capacitor for the high-capacity main parts. But there are a lot of missing Ha electrolytic capacitors, for example, the frequency characteristics and temperature characteristics of poor wells, and large leakage current and dielectric loss, etc. In addition, when the polarity is reversed or both ends of the applied voltage exceeds the specification was, the security will be destroyed, the electrolyte will be gasification and burst (commonly known as the so-called breakdown)
There are many external environmental factors will lead to deterioration in performance electrolytic capacitor, such as temperature, humidity, pressure and vibration, electrical impact include the voltage, ripple current, and charge-discharge. Environmental factors in the temperature of the capacitor life the greatest impact, and make the smaller capacitance, loss increases. In addition, electrolytic capacitors because capacitor losses than the other (internal resistance) is large, the ripple current caused by the heat of life will be greatly affected. In addition, some pure Class A amplifier bias current required to cause high fever, high fever easily lead to serious all the relevant parts to shorten life, among which the power center of this electrolytic capacitor is staggering. Heat will cause rapid deterioration of performance electrolytic capacitor life and capacitance are reduced to only a fraction of the original, this way is tantamount to losing the role of filter capacitor, it is easy to machine failures will occur.
Then we introduce several circles in the sound quality electrolytic capacitors: First up is the famous SPRAGUE capacitance, in the expansion of HI-END advertised inside the machine, an occurrence rate of the Bay, covered the Krell, Mark Levinson, Cello, and other famous Factory machines, the power supply filter must come by it sits, in addition to countless number of multi-audio manufacturers also use SPRAGUE capacitors. SPRAGUE American system of high capacitance electrolytic capacitors, blue rubber packaging products to its excellent performance and stability, and long life. Electrolytic capacitors in the previous high number was small, when imported, SPRAGUE capacitance is DIY fans in search of scrap metal heap baby, ship-breaking second-hand second-hand parts monopoly provider, SPRAGUE capacitance is very sought-after hot item. Even from the scrap heap to SPRAGUE capacitance of the Xu are already quite old stuff, but it used up the same satisfactory performance, which also shows the life SPRAGUE capacitance is how long. SPRAGUE, however, the name may no longer easy to see the future, because it has been Japan s Nippon Chemi Con capacitors to the acquisition, but SPRAGUE all production lines may also maintain the original materials and practices, but the scale of production may vary, so the capacitor appearance other than skin color packaging and the original SPRAGUE capacitance remains the same, but the mark has been changed Nippon Chemi Con small shield rather than SPRAGUE. A careful reader can observe the name of newly manufactured machine, filter capacitor still seem no different with the previous, but in fact the word trade mark is not SPRAGUE but a small shield.

Again is Germany s leading ROE electrolytic capacitors, ROE electrolytic capacitors in both the earlier and SPRAGUE capacitance can be said main audio brand in Europe and America only two choices, especially in Europe, audio equipment ROE capacitors used a lot, all kinds of horizontal legislation capacitor can often be seen on the circuit board. Speaking SPRAGUE ROE capacitor capacitance and HI-END audio equipment in the representation can Krell machine to do the expansion as a model, Krell power amplifier is the main filter capacitor sprague capacitor, the input stage and driver stage power amplification Ken capacitor , we use the ROE. Krell s preamp and digital equipment also follow suit, especially the Krell s preamp and digital equipment in the ROE capacitors are used for a certain use a liver-colored plastic shell packaging, EK variety of materials. ROE in the past most of the capacitor is golden yellow skin packaging, circuit board mounted inside the chassis golden one is truly beautiful, it could not help but think of glowing golden luster sound quality and tone, with a ROE of Australia as the main filter capacitor capacitance in design and in particular when exposed out of the capacitor to increase the equipment itself, advanced texture. However, recent ROE capacitors, small value capacitor packaging has been changed to black, and it is really frustrating in terms of aesthetics on.
Europe is really beautifully capacitance of its products, please move to the attention of Philips capacitors. Philips capacitors in these two years the new advanced equipment in the factory of the exposure is higher and higher, and covered the the price of the equipment, such as ONIX, expensive equipment, such as Goldmund, vacuum tube machine of the best god JADIS and the large number of other brands, Philips capacitors can gradually see where the strength of the domestic long-established supplier of advanced components, such as the original sound that has been strongly advocated Shantou Philips capacitors benefits. Philips capacitors packaging is blue, but the color is slightly more than the capacitance SPRAGUE, it has many series, including a more advanced model of its cans have many hexagonal shaped notch in order to enhance the mechanical strength of the capacitor, of course, cost is This will be more expensive.
Audio equipment used in film capacitors, fame first, most famous, the most important red magic pill or elixir known German WIMA container. Has not yet appeared in the early years when the so-called tonic parts, WIMA was the only commercially available high-level buy stuff. Although the materials and technological advances and market demand, various brands have been more advanced thin-film capacitor was dazzling, but should WIMA is the most well-known brands. The most famous WIMA capacitors, is undoubtedly the number of PP quality MKP-10 capacitors.
In WIMA, the audio products also use a lot, great history, is the same for the German brand ERO capacitors. ERO capacitors most commonly seen is green, some are blue, and WIMA also assembled on a board, side by side, it is truly beautiful. ERO is the brand of film capacitors, and a high ROE is another brand of electrolytic capacitors, the two letters the same, but in a different order, the reader is not confused. The same for the German brand, but audio products using them too much capacitance is Siemens, the brand electrolytic capacitors and film capacitors are the name of HI-END in Germany are willing to adopt plant MBL, and performed extremely well, so the strength can not be be underestimated.
Philips is a big business group, its manufacturing of products is really countless, from the most popular people s livelihood and home appliances, to the most cutting-edge space technology, the broad-based course, the production of capacitors, is not missing. It is home of the capacitor, is to present the appearance of a faint blue water, recently often found in audio equipment.
Rifa is a Swedish brand of high capacitance, quality common to the PP capacitor is blue, the sound performance characteristics and specifications are very good, but the price is very expensive, likewise, so there are very few audio manufacturers use, but I just use that three The sound of this brand name factory, you can probably understand its strength lies. That the three do? Danish Gryphon, U.S. Mark Leivenson and Cello.
Wonder capacitor capacitance and Relcap are quite a few years off while the thunder of the high capacitance, Wonder Capacitors to Counterpoint machines use the most famous, Audio Research also uses it, the appearance of white cylinder, sealing glue is green; Relcap places the most famous use of Audio Research, the appearance of yellow oval cylindrical.
French Solen capacitors also became popular very quickly in recent years, its appearance was cylindrical, black skin, with both ends sealed plastic brick red and gray two. It is by far, the only mass production of large-capacity capacitor MKP (up to 200F) of the well-known manufacturers, so Solen capacitors are extensively used in high-level speaker crossover among the examples are well-known author of: Danish Dynaudio speakers, United States of Infinity speakers (including IRS-V alt column), France JM Lab speakers (the flagship of the ALCOR and UTOPIA is more unique in the horn back on the heart, showed off a transparent acrylic super special custom Solen capacitors, to show the material of the ordinary.) In addition, many well-known manufacturers in the crystal machine or tube used in both the electrical and mechanical way too many.
Capacitance to the history of MIT, is the youngest high capacitance, the listing date, maybe even three years not to, but since a launch, which can be "sensational martial arts, alarmed many religions" to describe, was once the HI-END Sound Circle the topic. One reason for its special structure, MIT is a complex capacitor capacitance (Multi cap), meaning that a capacitor is actually an internal capacitor in parallel by multiple composite, what advantage do it? Can once again reduce the capacitor s equivalent series resistance and internal equivalent series inductance, capacitance closer to MIT makes an ideal capacitor, so all the technical specifications and some features are also very good Lo! Of course, doing so is to pay a price, MIT capacitors expensive price, enough to make use of it to discourage manufacturers or individuals, which is its second notable place. In addition to its capacity in terms of the same size is relatively large, in particular about the density of circuit components on the real equipment, ease of application would be restricted. Its appearance is white oval cylindrical, lead is very thick, sealed plastic is black, while metals in foil and it has two types of film.

Again is Germany s leading ROE electrolytic capacitors, ROE electrolytic capacitors in both the earlier and SPRAGUE capacitance can be said main audio brand in Europe and America only two choices, especially in Europe, audio equipment ROE capacitors used a lot, all kinds of horizontal legislation capacitor can often be seen on the circuit board. Speaking SPRAGUE ROE capacitor capacitance and HI-END audio equipment in the representation can Krell machine to do the expansion as a model, Krell power amplifier is the main filter capacitor sprague capacitor, the input stage and driver stage power amplification Ken capacitor , we use the ROE. Krell s preamp and digital equipment also follow suit, especially the Krell s preamp and digital equipment in the ROE capacitors are used for a certain use a liver-colored plastic shell packaging, EK variety of materials. ROE in the past most of the capacitor is golden yellow skin packaging, circuit board mounted inside the chassis golden one is truly beautiful, it could not help but think of glowing golden luster sound quality and tone, with a ROE of Australia as the main filter capacitor capacitance in design and in particular when exposed out of the capacitor to increase the equipment itself, advanced texture. However, recent ROE capacitors, small value capacitor packaging has been changed to black, and it is really frustrating in terms of aesthetics on.
Europe is really beautifully capacitance of its products, please move to the attention of Philips capacitors. Philips capacitors in these two years the new advanced equipment in the factory of the exposure is higher and higher, and covered the the price of the equipment, such as ONIX, expensive equipment, such as Goldmund, vacuum tube machine of the best god JADIS and the large number of other brands, Philips capacitors can gradually see where the strength of the domestic long-established supplier of advanced components, such as the original sound that has been strongly advocated Shantou Philips capacitors benefits. Philips capacitors packaging is blue, but the color is slightly more than the capacitance SPRAGUE, it has many series, including a more advanced model of its cans have many hexagonal shaped notch in order to enhance the mechanical strength of the capacitor, of course, cost is This will be more expensive.
Audio equipment used in film capacitors, fame first, most famous, the most important red magic pill or elixir known German WIMA container. Has not yet appeared in the early years when the so-called tonic parts, WIMA was the only commercially available high-level buy stuff. Although the materials and technological advances and market demand, various brands have been more advanced thin-film capacitor was dazzling, but should WIMA is the most well-known brands. The most famous WIMA capacitors, is undoubtedly the number of PP quality MKP-10 capacitors.
In WIMA, the audio products also use a lot, great history, is the same for the German brand ERO capacitors. ERO capacitors most commonly seen is green, some are blue, and WIMA also assembled on a board, side by side, it is truly beautiful. ERO is the brand of film capacitors, and a high ROE is another brand of electrolytic capacitors, the two letters the same, but in a different order, the reader is not confused. The same for the German brand, but audio products using them too much capacitance is Siemens, the brand electrolytic capacitors and film capacitors are the name of HI-END in Germany are willing to adopt plant MBL, and performed extremely well, so the strength can not be be underestimated.
Philips is a big business group, its manufacturing of products is really countless, from the most popular people s livelihood and home appliances, to the most cutting-edge space technology, the broad-based course, the production of capacitors, is not missing. It is home of the capacitor, is to present the appearance of a faint blue water, recently often found in audio equipment.
Rifa is a Swedish brand of high capacitance, quality common to the PP capacitor is blue, the sound performance characteristics and specifications are very good, but the price is very expensive, likewise, so there are very few audio manufacturers use, but I just use that three The sound of this brand name factory, you can probably understand its strength lies. That the three do? Danish Gryphon, U.S. Mark Leivenson and Cello.
Wonder capacitor capacitance and Relcap are quite a few years off while the thunder of the high capacitance, Wonder Capacitors to Counterpoint machines use the most famous, Audio Research also uses it, the appearance of white cylinder, sealing glue is green; Relcap places the most famous use of Audio Research, the appearance of yellow oval cylindrical.
French Solen capacitors also became popular very quickly in recent years, its appearance was cylindrical, black skin, with both ends sealed plastic brick red and gray two. It is by far, the only mass production of large-capacity capacitor MKP (up to 200F) of the well-known manufacturers, so Solen capacitors are extensively used in high-level speaker crossover among the examples are well-known author of: Danish Dynaudio speakers, United States of Infinity speakers (including IRS-V alt column), France JM Lab speakers (the flagship of the ALCOR and UTOPIA is more unique in the horn back on the heart, showed off a transparent acrylic super special custom Solen capacitors, to show the material of the ordinary.) In addition, many well-known manufacturers in the crystal machine or tube used in both the electrical and mechanical way too many.
Capacitance to the history of MIT, is the youngest high capacitance, the listing date, maybe even three years not to, but since a launch, which can be "sensational martial arts, alarmed many religions" to describe, was once the HI-END Sound Circle the topic. One reason for its special structure, MIT is a complex capacitor capacitance (Multi cap), meaning that a capacitor is actually an internal capacitor in parallel by multiple composite, what advantage do it? Can once again reduce the capacitor s equivalent series resistance and internal equivalent series inductance, capacitance closer to MIT makes an ideal capacitor, so all the technical specifications and some features are also very good Lo! Of course, doing so is to pay a price, MIT capacitors expensive price, enough to make use of it to discourage manufacturers or individuals, which is its second notable place. In addition to its capacity in terms of the same size is relatively large, in particular about the density of circuit components on the real equipment, ease of application would be restricted. Its appearance is white oval cylindrical, lead is very thick, sealed plastic is black, while metals in foil and it has two types of film.
car stereo to listen to the best results
Would like to improve the sound quality car audio system? Start with the audio to start.
Narrow tape frequency response, noise, do not have to be considered. Some of the original car audio systems to install a CD drive,
that can improve the sound quality is simply not justified. The transformation to a Beverly sedan, for example, owners of the original
car audio systems to install a six-disc CD drive, the installation of one pair of rear 6 × 9-inch speaker and active subwoofer. Although
the audio upgrade for the CD, but the sound quality has not been significantly improved. Or tape drives using the playback system, CD
signals from the FM radio band is still received in, and there will be loss of sound quality, frequency response has been limited, and
there will be noise, CD s advantage not to play, the sound level does not and thorough feeling.
As can be seen from this example, improve the sound quality is the overall project. In the establishment of sound system, all
equipment should be maintained with a consistent style, or may result in the appearance, function, use, indicators and other aspects
of disharmony.
To CD, MD do not VCD, MP3
If only to play a sound, select the host or CD, MD or DVD. VCD sound quality is poor, not the best; MP3 is a compressed format,
although the increase in sound processing circuit, but the sound quality is still not as CD; DVD sound quality close to CD, but the
overall comparison, still not as CD; MD and CD sound quality less , but the sound is slightly hard.
To “genuine” and not the equalizer
Host should be used without any modification of the signal model, that is called “authentic.” Signal is modified, the waveform
distortion, so the music play out is not ideal. “Genuine,” the host is not the best graphic equalizer, field-effect (such as: theater,
square, studio, etc.). Of field-effect modification, the original signal will produce changes, loss of the original sound quality.
Do not 1bit to 24bit
Select a model to look at frequency response indicators, the sound quality without any additional modification of the function. Shop
selling CD, audio labeled 20bit and 24bit. 20bit and 24bit high resolution in order to make music full show. Ordinary sound mostly 1bit,
fever sound more high-level bit. Only in such a machine to play, will demonstrate its degree of detail.
Do not want to high-power distortion
If the host directly promote the speaker, to select high power output. Now the host output power is generally 4 × 50W, mainly to
reduce the distortion. If the host pre-output, to select high output level, and aims to improve the signal to noise ratio, output level
generally 2V, the best choice for 4V output. By the way, CD recording to use genuine, with the disk printed on “DDD” the best,
produced this CD, the sound quality is good.
Do not plan to consider upgrading to facilitate cheap
Do not deliberately seeking too much functionality, as long as the equipment s capabilities to meet the basic requirements for; but do
not plan cheaper, missing basic features they need. Equipment input and output ports to be considered in advance, players, game
consoles, handheld DVD, computer, speaker phone so you can enter the default port; output port should also consider the left, right,
front, back, bass, inconvenient to use in order to avoid future upgrades.
audio listening evaluation of method and language
A set of audio playback quality is good or bad, in addition to the technical specifications with the objective, but also with the
subjective listening experience. Because so far, some subjective feelings of not using the appropriate method described in the
technical specifications Moreover, for people to listen to the sound is so subjective listen test audio quality has become a last resort,
and especially for consumers.
Human auditory organ and brain, to an integrated voice information according to different proportion of the various indicators, quick to
make sound judgments. However, this judge can not rule out the biggest problem is the evaluation of subjective factors (such as
habits, hobbies, quality listening experience, etc.), resulting in large dispersion of evaluations, consistency is poor. Sometimes
evaluation can not explain the problem, so nothing to comply with the designer.
Therefore, we must improve the listening evaluation methods, evaluation criteria provided the environment to determine the technical
evaluation of the meaning of the term, a unified terminology. Quality evaluation of about 30 terms, its meaning and its related
technical indicators can be found in the monograph. There is only divided into different levels according to the following three groups:
A, a minimum term
1, the clear (translucent) – turbidity
2, smooth (rounded) – rough (dry)
3, light – dark
4, full – dry (thin)
5, soft (soft pine) – Spiked
6, the intensity, strong – weak
B, whole language
7, the balance
8, three-dimensional
9, presence
10, large degree, the open degree
11, depth, sense of distance
C, to add language
12, the stretch – block
13, soft – hard
14, moist, there is glory, there is water – no glory, dry
15, clear, refreshing – fuzzy
16, fusion – loose
17, clear level – is not clear
18, clearly ———- unclear (such as speech intelligibility)
Excellent as a sound source selection evaluation of the program source to listen to, especially for the amateur who should choose their
own familiar programs. Thus, in different combinations in the Top sound quality is more able to listen to the difference. For example,
you want to buy a set of equipment, it is best to find a good quality recording, non-linear distortion is small, plump and have a high
musical bass than the fragments of the CD, and in relatively good combination of audition, to be very deep impression, and then use it
to test the combination of hearing you want to buy is easier to listen to the difference. In addition, some of the selected program
type is more conducive to a wide range of equipment to listen to comment.
listen to sounds of car audio use and maintenance tips
Car music has become an integral part of automotive life, when the high-quality CD surround sound, beat notes pouring out of the
drive will immediately feel comfortable together. But most owners only know to enjoy the wonderful music brings pleasure, but do not
know how to protect its “voice”, so Amu bring you the use of sound maintenance techniques.
Refused to “decadent music”: audio using the four fear:
As we all know, there are four electrical appliances fear: a fear of damp, second, fear of dust, three fears severe shock, the four
mutations in fear of amplitude. car audio, too, as long as people can understand what they do not like, it is easy to protect them
anymore.
First, the fear of wet
People always love a clean car interior will be cleaned, should be noted that, when people clean the car interior, you should try not to
spray in the direction toward the sound of water, liquid detergent like substance. Dust on the host audio, you can wring a towel to
wipe dry. Also, car interior cleaning, the best window for some time, so most of the water evaporates and then shut down the car
window, you know, electronic products, the biggest killer of all parts of the controller is damp.
Second, the fear of dust
Dust on the car stereo s injury is very common, for example, advance and retreat disc problems, its reading is not difficult or even its
reading, and radio interference effects, are likely to be caused by dust violations. So when your car when driving in the dirt road, try
not to open the window, to avoid the large influx of dust from the vehicle interior, and, it is best to adjust the air circulation within
the outer loop, to avoid dust on the sound against.
Third, the fear of severe shock
Although the general process of moving, car audio jitter will not cause severe vibration host (unless out of the car accident), but
sometimes for some reason, people need to be removed to sound, this time we should pay attention, do not hard shaking or tapping
sound. Suffered severe shock because, after some internal parts may sound loose or damaged, causing serious problems. In general,
even for the maintenance of sound waiting for the host, should take a light-light approach.
Fourth, the fear of mutation amplitude
To avoid the use of sound which suddenly put maximum volume, so easy to make a bad speaker coil, the amplifier will be affected, will
increase the amplitude of a sudden burning power amplifier.
Maintenance of “rhythmic”: audio also needs routine maintenance.
Car audio and other components as needed routine maintenance, do not go unchallenged, car audio routine maintenance include the
following.
Often with a small swab moist:
Sound pressure in the cassette machine pulley and CD player heads are easy to accumulate dust and dirt. CD player is the most
important parts of the laser head, because the laser is more expensive wearing parts and should focus on conservation. Although
some car audio in the design process are considered a dust problem, but protective measures are necessary, you can often use a small
swab moist cassette, cassette and CD player and sound system disc slot panel. The correct approach is to use a damp cloth to gently
suck the dust down. As for the buttons and knobs to clean up, you can again use a cotton swab.
With the clean-up tools clean the tape and CD:
In addition to maintaining the cleanliness of the host audio, tape and CD but also to ensure cleanliness. Dirt on the tape and CD player
will not only affect the sound, will sound even cause damage. CD player laser head at high speeds, if you encounter dust, will deviate
from the original laser laser track, resulting in sound distortion, and laser damage. It is understood that the cleaning tape and CD audio
-visual tools in most stores you can buy.
Toyota Previa ultimate audio conversion fever evaluation
Test vehicle: Toyota Previa
Sound System: Alpine + DLS + poetry Finney
Toyota Previa single configuration:
audio: ALPINE 9990
Additional display: proud of who-resistant ceiling display
Before the sound field speaker: Sinfoni 45.2X push DLS No1 treble, push the DLS No 6.2 50.4 bass
Center speaker: 50.4 to push DLS UP1 + UP2.5
Surround speakers: DLS A3 push DLS UP6
Bass System: DLS A6 15-inch bass to push oxygen
Other: Power processor poetry Finney POWERBLOCK
Audio industry often sound AV system with stereo sound in the end the kind of fever, better sound quality debate, SACD and DVD-
AUDIO from there since the top multi-channel music, and more people slowly recognizing the multi-voice Road in the atmosphere,
contrast, audio and video and immersive surround combined with a sense of feel the charm of a multi-channel. In car audio conversion
in the AV, AV in order to achieve both good results, but also have a fever of sound, which requires matching from the equipment,
system debugging, and channel configuration should have a wealth of experience and excellent skills.
System 4.5
ALPINE s 9990DVD player equipped with a system of H990 decoder ALPINE, and ALPINE it can be said that the 701 processor in the
industry reputation, not only a variety of AV, such as DTS and Dolby Digital decoding, but also the sound of each channels in accurate
delay calibration and EQ balance. Before the sound field, the center channel speaker DLS using SINFONI match the way, and the use
of active electronic crossover; channel surround sound using two six-inch speaker drivers DLS A3 DLS UP6. Bass system uses oxygen
15-inch loudspeakers, with DLS A6 drivers.
In order to ensure a good sound, some poetry Finney power supply processor, and added two large capacitors to ensure stability of
the bass impact and power supply.
4.5 modified car ride
Host installed in the dashboard, re-mold and spray into the dashboard color processing with the same texture, do not remind not see
signs of modification. Treble mold in the A column, in order to avoid the reflections also opened a small tank. The center speaker
installed in the dashboard just above, and point to the radiation angle. The main channel of the bass is original way, directly mounted
on the door, knocking door to feel the door after the effective acoustic treatment inside. DLS speakers in the door handle it properly
after the very good results, such as sealed, and have sufficient rigidity. Surround sound installed in the body of the rear wall, near the
windows installed in the vicinity of the treble, so that the whole surround sound high enough.
The center channel can be the main channel (front left and right channels) using the same amplifier and speaker unit, the sound
quality, sound consistent. Modified car in the surround channel is one of the difficulties, in order not to damage the car interior,
compromise is to try to pretend to be a higher speaker in the interest of car theater surround sound standards.
Trunk modified 5
Trunk can be modified to reflect the modified very intuitive process technician level. 15-inch subwoofer system, four power amplifiers,
equipment and more, but this car did not show very crowded, but very simple. Whether it is low-speakers inverting amplifier tubes of
metal mesh or a shelf, all have very sophisticated. Because of the low speaker using the spare space on the abolition of the spare tire.
Sound 4
The 9990 ALPINE car stereo DVD player is a top player, DLS pay attention to the voice of the true frequency of natural fullness and
restore. Although the DVD playback system, but as long as the match is good, pure CD sound quality than the system worse.
In the play “Hotel California” DVD live version, DLS is very obvious characteristic mellow tenor, treble up high, but not fat thorn, 15-
inch bass is not the phenomenon of partial fat. With Dolby Pro Logic II to listen to a CD, surround sound field, and each other before.
Image effects 4.5
9990 7-inch screen resolution is very high as the table, but the King is the best video effects, 15-inch display ceiling civil. In DVD
playback, the image of the gray level of clarity, and because the big screen, image perspective it does not matter. At the same time
when rapid change in the picture, there is no more than mark, trailing phenomenon. The screen hue, color temperature debug
properly, so a variety of gray shades are an excellent way to get the performance, colors are somewhat neutral.
Voice dialogue 4.5
The performance of vocal dialogue is this car s strengths. Whether it is music or large, etc., from the definition, as well as audio-visual
combination to restore the degree of accuracy, the re-molding of the center channel, DLS UP sound performance can be said that
the best interpretation of the human voice. In the audio-visual integration, since the former location of the sound field of the treble,
the treble position in the center channel is basically a horizontal line, located in the center vocal, and the position of left and right
channels can be really good combination of audio and video.
Reproduction 4.5
AV sound effects and the effect of fever are different, AV is the effect of impact, a sense of atmosphere, while the fever is the
realistic sound effects and appeal. “Crouching Tiger” in the background music will be slightly oppressive atmosphere of contrast cello as
if the ground, fight scenes and exciting restaurants, demonstrated by the impact is also very exciting.
But surround sound with a little low, AV theater requires the reduction effect of a certain height, but due to the installation location,
it will affect the actual response.
News 4
The use of large diameter and low enough to ensure sufficient power amplifier is dynamic. Previa is equipped with the various channel
is ideal, but the center channel as a 2.5-inch mid-range, large volume bass can only be converted to the left and right front channels.
Vented 15-inch speakers in the hatchback car fully meet the requirements of various types of discs, such as listening, such as “Air
Force One” in the tanker explosion, “Lion King” in the drum group performances are not distorted phenomenon, the dynamic has no
deficiencies.
4.5 overall comments
Good technology, good quality guarantee. Especially those who can not see the crafts, such as the door s handle, bass cabinet
configuration. King of the process whether it is a large representation of the appearance of the treatment, as well as some details of
the process or wiring practices are very much in place, due to advanced AV processor, rich experience, AV sound effects and the
effect of fever here are perfect with.
experts to explain the importance of the car stereo capacitor
Capacitor car audio how important? Readers may only know the kind of sound system installation in the power side, above a large capacitor with a voltage meter, but in fact the basic components of the electrical capacitance, including the host, the former class, amplifiers, speakers and even a passive crossover , a variety of specifications and construction of the capacitor are ubiquitous, and its importance can be seen! However, due to electrical theory is too difficult, the author of this capacitor in the power supply end only for the principle of operation, and small hands and feet through the capacitor to improve dynamic performance of the two stereo sound to be profile, hope to make readers more clearly the use of capacitance understanding.
Capacitance – fast discharge current of the lake used in car audio system power side of the capacitor (Capacitor), by definition, if you can hold a current thing. Plain that analogy, if the car alternator and battery as the source of the river, the river current as to the operation of the amplifier as the use of river water tankers, like that between the source and the capacitance between the lake water tankers.
When the water tankers inefficient work, the flow of the river can cope with normal driving water tankers, water tankers required when running heavy loads quickly from the river source water, often in short supply, even with a fixed water tankers. Then, if we build a waterwheel between the lake and the source, the source of the water when the water too late to drive car, on the use of stored water in lakes and quickly added, will be able to maintain the operational efficiency of water tankers, this is the role of capacitance !
In addition, the capacitor has a fast charge and discharge characteristics. When the amplifier high-load operation, a large amount of current moment, at the same time, automobile generator and battery power supply may not be timely, resulting in decreased efficiency of the power amplifier, the sound quality associated impairment. However, if coupled with fast charge and discharge the capacitor, the amplifier need to momentary high power, that will power the generator and the battery time to the moment, for the power amplifier to maintain a stable electricity supply, and then quickly filled with electricity from the generator side, for the next “impulse” (high-power amplifier output) to prepare.
How to choose the capacitor?
Market, the type of capacitor considerable modification, consumers will purchase access to the identity, the first is how much Farah (Farad), or how many μF, it represents what does that mean? F (Farad) is the capacitance of the unit, usually written on the capacitance μF, on behalf of a millionth of Farah, many capacitors marked 1,000,000 or 2,000,000 μF, in fact, 1 farad 2 farad (perhaps more than the number of 0, will sell the better right?) Importantly, the maximum output power to 500W, 600W single power amplifier and the like, at least 0.5F ~ 1F capacitors to ensure the ideal power supply efficiency, and consumers like to change 2F, 3F, or 5F above capacity of the capacitor depends on personal preference. But the greater the capacitance of capacitor, the higher the price it!
Second, the capacitance also includes resistance, voltage, temperature, capacitance error value, the loss angle, leakage current, ESR / ESL … … and other data, they often are not marked on the product, and these more difficult information, consumers purchase capacitor, in fact, do not require in-depth understanding.
Capacitance tricks
In the end of the installation of car audio system power capacitors, power amplifier can be sure that there is ample supply of electricity, the transient response for voice, bass saturation, speed, a considerable improvement in results. However, many people blindly modified when a larger capacitor, you thought, the greater the capacity of the capacitor, the larger the area of ??the lake as the same, regardless of water, drainage, need more time? Therefore, the larger capacity capacitor, but charge and discharge more slowly.
This problem is not no solution, consumers can go to the electronics store, buy some capacity 33000,22000,10000 μF, 20V DC voltage over the DC capacitors have polarity, and then follow the positive and negative electrodes of, they are parallel in the original large-capacity capacitor side, so that if the construction of the Great Lakes next to a small lake, with the capacitance, charge-discharge rate is fast enough, the sound of compaction performance better! In addition, the price of a small capacitor is not high, as long as readers spend a little money to buy, you can exchange for better sound, why not?
Furthermore, many people like to watch the voltage on the capacitor table, or a colorful flashing light, in fact, these things, for the power system, are considered a part of the load, of course, the less the better myself.
Sloppy sound piecemeal
Many stores or manufacturers of capacitors hands and feet, often moving in to steal by capacitance, reducing the manufacturing costs of fronts, and this, consumers are very difficult to be discerned from the appearance of the capacitor, pony Huge said:
1 have another lighting capacitor voltage meter, installed in the car was beautiful!
Indeed, with the light and the capacitance voltage meter, texture looks relatively high, and the voltmeter can also help users understand the operation of the state electrical board. However, light and voltage meter on the circuit for both the system load, the more and more as a power grab power amplifier, so the stereo sound performance, there is a negative impact!
(2) the capacitance of the brand, to ensure adequate electrical capacity and high efficiency:
Really, the market capacity has too many brands and styles, it is difficult to say which one capacitor shoddy version, the occurrence of electric capacity and misbranded phenomenon. Therefore, the capacitance in the naked eye can not tell, you can hand-shake or product to see if there is no unequal distribution of weight, or have something to shake them, and if so, this capacitor is often filled by gluing weight, capacitance sure enough! As for the professional audio shop that should come up with a capacitance meter, the measured capacitance to convince consumers.
car audio installation completely Raiders – Purchase articles
Drivers friends probably encountered traffic jams, here anxious as ants on a hot pan, but the traffic there motionless. At this time, why
do not you listen to music? So that the long wait for a casual good time. So what? Quickly to install car audio now! However, before
you decide to install a car stereo, it is best to first understand some of the relevant knowledge, which you certainly are useful.
Purchase of articles
Friends of the driver,
Buy a high quality car audio there is very difficult. Currently, the car audio market, attractive profits, many roadside shops are mostly
without professional installation technician training, installation of car audio often a variety of failures, to traffic safety hidden trouble.
So, how to choose rest assured that the installation of car audio and scientifically, effectively maintain it? Recently, the reporter visited
a number of car audio shop and the industry, they remind you start from the three chapters, you will easily have a Heart of car audio.
Face of the market an array of various brands of sound, very easy to know what to do, how to choose sound there are some basic
rules to follow.
1 according to their taste and affordability may be
This is a clear understanding of their specific expenditure is the cost, because a good sound natural to have a good price. In the high
-end luxury cars generally have more advanced professional audio, in which European and American products better, the sound quality,
sound more professional than the Japanese products. But now some well-known Japanese brand car audio brands have also
introduced some of the fever to compete with Europe and America. Although performance is good, but the price is really amazing,
definitely the real materials, to achieve its target value listed on the nameplate and long-term sustainable use. Mid-range audio
equipment such as the selection is none other than non-Japanese product, its brand in the professional car audio equipment
accounted for 2 / 3. The ratio of price and performance value for money, and from the functional completeness of the shape and
appearance, decor and sophisticated technology, etc., but also in Europe and America can not compete with the products.
(2) to recognize whether it is really the brand
Now on the market for vehicle audio equipment businesses particularly, in order to avoid buy a fake and shoddy products, the best
depends on whether the business owns the brands of audio equipment factory authorized designated agent license, whether the
service capacity and quality three bags of commitment measures. Another excellent product, we can not guarantee that the
operation will not be a problem. To address the conservation and car audio troubleshooting problems in the purchase of sound mind
when the selected audio brand in the local service professional certified repair stations. Only with perfect audio brand of service in
order to ensure the car s sound in the event of failure to be professional, convenient service.
3 to consider the ability of the host amplifier
Try to use the power of the amplifier is greater than the speaker instructions. In the long-term use because of the small high-power
amplifier output, easy to burn, can lead to poor sound quality, distortion and other failures. For example: the sum of all the speakers
indicated power of 100 watts, the amplifier power to 100-l50 watts, in order to have a good match.
4 To understand the speaker s performance
High-grade will not be much difference between the performance of the host, speaker of the difference is amazing. A speaker at
every turn marked with a few hundred watts of power, many insiders are confused, many speakers you just use it to mark the 1 / 10
the power to try a few minutes, I am afraid will be exposed to a white smoke.
5 To listen to sound, sound effects
Listen, it is best to find several dishes representative of the songs, music, percussion and other discs, the pure sound of various
degree of identification, and then determine whether to buy.
6 keep good products, invoices, proof of maintenance
In order to avoid unnecessary disputes, and protect their interests, Take good care of your product invoice, proof of maintenance.
