The good stereo set makes you place oneself music hall to put a recording with sturdy low frequency, like big drum, the bass ＢＡＳＳ , the bass flexible number, bass list Huang tube, diagram Ba Hao, French horn etc., add the volume to enough and greatly, then gradually decrease, under the circumstance of any volume, can hear clean, deep and low, loose permit appropriate low frequency is high-quality tone color.In addition, the good stereo set has the voice field of panorama type to reappear ability, while listenning ability music at you front of a big slice of district reappear, not from list the loudspeaker unit sent out and let people had the felling to place oneself music hall.Superior quality of tone color\\ s still including in the whole car compartment can hear the voice of balance reality, for example broadcasting one can obviously classify an or so track recording, superior quality of the sound quality is to try to listen to an or so track can hear respectively two tracks send out of all voices, and can hear the car stereo set of balanced consistent music original package facilities not necessarily good on the different seat.Refitting car stereo set system is the vogue that the modern plays car one clan.However, in the aspects of refitting a car stereo set, many people exist many understanding mistake area.According to understand, the regardless importing or domestic sedan is also regardless medium file or upscale car, the stereo set system of its original package how much all have some to make people disappoint.Because the car is after all a car, not multi-media computer or home appliances, cool love stereo set of friend\\ s only passing to refit just can satisfy a his/her own sense of hearing high standard request.The many people thinks the stereo set facilities on original package of car must be good stereo set facilities, this is one of the mistake areas.This personage says that usually car host and trumpet of original package compare a wanting of stereo set fancier imagination to differ a great deal, is that the even if upscale car is no exception.Especially a lot of car stereo sets are in installing bass the existence lack and and is hard to attain high fidelity request.Moreover, car owner at refit a stereo set of, usually feeling should adopt host, trumpet and other accessorieses all a series fix menu in restaurant that company produces, this is again a mistake area.Because truely produce the company of professional car stereo set device among nations, isn\\ t the profession been known for because of the series fix menu in restaurant of its production, but exactly been it very strong some one device but drive industry approbation.For example:Japan produces of host, manipulating of its electronics figures science and technology and sensitive convenience function takes up the running a nation, but the trumpet of Euro-American production, it superior quality of the fine foundry technique of material and pure quality and traditional handicraft again that day originally produce a company to compare.So before the car stereo set refits, want to choose a good adoption first which companies the professional device of production, all materials choosing isn\\ t a good choice from a product of company.

The current level of program source device and the power amplifier has been done is very high, the sound system consisting of a high-quality audio, high
-quality amplifier and speaker system, the playback quality depends primarily on the speaker of the Speakers also known as speaker systems, it is
extremely important aspect of the sound system. Great sound playback quality of the entire sound system.
Speaker classification, common in the professional audio, classified as follows:
1 by the use of the occasion: divided into two major classes of professional speakers and home speakers. Home speakers are generally used for home
playback, which is characterized by delicate playback sound quality and more refined appearance `beautiful, the playback sound pressure level is not too
high to withstand the power is relatively small. Professional speaker in general for the dance hall `karaoke hall` theaters `halls and sports stadiums
and other entertainment venues. The high sensitivity of professional speakers in general, the playback sound pressure, intensity, and to withstand the
power compared with home speakers, the sound quality rigid, the outlook is not very sophisticated. Professional speaker in the monitor speakers, its
performance home speakers closer to the appearance is generally more sophisticated `small, such monitors are often used in home Hi-Fi sound system.
2 Press the playback frequency: can be divided into full-band speakers bass speakers and subwoofer. The so-called full-band sound is able to cover
the low-frequency `IF and high frequency range playback of audio. Full-band sound of lower frequency is usually 30Hz-60Hz, maximum frequency of 15KHz-
20KHz. Only in the small and medium sound system with a pair or two pairs of full-band sound to fully take on the task of playback. The bass speakers and
subwoofer are generally used to supplement the full-band sound of low frequency and ultra-low frequency sound for speakers. The type of speaker is
generally used in the `medium-sized sound system, to strengthen the sense of the intensity of low frequency sound and shock. Use, mostly through an
electronic crossover (crossover) frequency division, the low-frequency signal into a dedicated bass amplifier, and then push the bass or subwoofer.
(3) by end-use: generally divided into the main playback speaker. Monitors and back to listen to speakers. The main release the audio speakers are
generally used as the main speaker sound system, bear the main playback tasks. The main level audio speaker performance to a great impact on the quality
of the playback of the entire sound system, can also choose the full-band speakers plus subwoofer combination playback.
Monitors for the control room, recording studio for program monitoring use, it has a small distortion, wide and flat frequency response, very little
modification to the signal characteristics, most of faithfully reproducing the original appearance of the program. Back to listen to the speakers, also
known as stage monitors, and general use for the actors or members of the band on stage or in dance halls to listen sing or play sound. This is because
they are located behind the main playback speaker on the stage, can not listen carefully to their own sound or the band playing acoustic, it can not be
well with or find the exact feeling, seriously affecting the performance effects. Generally return to listening to the bevel-shaped speakers made, on the
ground, which can be placed on the stage will not affect the overall shape of the stage, but also on the stage to listen carefully to playback, not
caused by audible feedback to the microphone howling.
The press box structure: can be divided into a sealed speaker, vented speakers, labyrinth speakers, acoustic tube speaker and multi-cavity resonator
speaker and so on. Which professional speakers used the most is inverted relative to the speakers, which is characterized by wide frequency response,
high efficiency, sound pressure, in line with the type of professional sound system speakers, but because of its low efficiency, it is less professional
speaker applications, mainly for home speakers, only a few monitor speakers with closed box structure. Sealed speaker has the advantages of simple design
debugging, wide frequency response and good low-frequency transient characteristic, but the higher the requirements of the dial sound unit. In a variety
of speakers vented speaker and sealed speaker occupied the majority of the proportion of many structures in other types of speakers, but the proportion.

Line array speaker\\ s use of technology: First, what is the goal of high-quality sound system? Provide clearly defined, from seat to seat as consistent as possible frequency coverage. However, traditional methods of speaker group, the interference due to the interaction between the speakers, to achieve this goal, there are inherent limitations.
Provide better sound quality (less comb filtering), better coverage, more efficient use of amplifier power system.

amplifier is the heart of the sound system, the size of the power amplifier, the quality is
good or bad music player plays a vital role. Ordinary car amplifier design in the host, the
general power of 10W ~ 45W, but this does not listen to multi-level high-power digital
music, in order to make the sound to achieve the best results, we must add a separate power
amplifier in the system, the rose to power supply 12 volts to 35 volts to 45 volts to
promote high-voltage high-power speaker, so dynamic range increases, the music can be more
perfect play.

The AV cable is short for home stereo audio cable (Audio Cable), and video lines (Vidio Cable). Audio cable video cable, can effectively eliminate external electromagnetic interference, and the original Khan flavor to transmit signals, we say this is a high quality line. A classification of home audio and main functions: home stereo is usually divided into pure audio and home theater audio two categories. Pure sound, also known as HI-FI audio, by the pure power amplifier (only two-channel output), speaker and disc players, generally used to listen to music and songs. Home theater sound, also known as the AV component systems, two-channel playback of music and songs, can also play a six-channel home theater disc. \"Fans\" in the general play of pure sound, but mainly to listen to Western classical music. 2, the relationship between fiber-optic lines, coaxial and decoder and amplifier: the disc player itself can be \"reading\" and \"decoding\", but in order to reduce costs, its decoding functions are generally primary. In order to enhance the \"decoding\" series, so that the sound becomes more beautiful, between the invention of the independent decoder and amplifier with a decoding function, and thus have a connection disc players and decoders, CD and decoding amplifier a \"bridge\" – fiber-optic lines and coax them to disc players \"read\" the digital audio signal transmission to the independent decoder or amplifier with a decoding function decode an audio signal. This transmission is often used in high-end audio. 3, audio cable, video cable, coaxial cable can not mix: appearance, video cable, audio cable and coaxial line of the body and two terminals constitute, and are relying on the inside of the metal wire core transmission signal. Therefore, it was for the sake of expediency, or less demanding arbitrary three mix. This can also lead to communication number, but the sound and picture quality is certainly damaged. Silver Leaf Wang AV cable used in the production of the three characteristics and uses of different structures and materials to ensure a true to the music and images, two functions the same AV cable is good or bad should have conditions: ① both prices and grades must be near; (2) must be used with a stereo, with a piece of music, the same volume, same listening environment; ③ The use audio and yindie of high-grade, too low to itself, will be issued by the noise so difficult to compare. How to give a reasonable sound optional AV cable? AV cable in the audio transmission signal from the \"bridge\" role. According to the AV cable for audio grade matching the same grade, so in order to make the audio sound effects to get better play. In general, high-end audio portfolio, the AV line of the investment ratio of 20% is more reasonable. Generally sound, we can not use too much low-end AV cable, which will not only attenuate the signal and the transmission signal is vulnerable to external electromagnetic interference, and ultimately lead to sound distortion. That are willing to spend money on sound rather than willing to spend money to buy the practice of the AV cable, in fact, with the Mercedes car to the petrol station and 90 # gasoline is no different on the surface, saving money, but eventually lead to bad results. Should be noted that the AV cable in use: the different functions of the line can not be free to mix, for example, use coaxial audio cable replacement, etc.; 2: AV cable when in use so as not to bend, and preferably away from power;: AV cable enough premise should be as short as possible, the extra length will only increase the signal loss; 4: The size of the speaker wire should be selected depending on the size of the sound power. Too small, the signal transmission by stagnation, the speaker unable to pay a good voice; too large, the signal loss increases, the increased burden of the power amplifier, speakers also unable to pay a good voice. 5: AV cable with external connection must be tightened. Poor contact (such as collapse, etc.) that will cause audio noise is severe will cause the components to burn out. : The AV line after a certain number of years, the core has metal terminals and wires may appear oxidation (\"aging\"), which would affect the sound effects, and should be replaced according to the actual situation. Silver Leaf Wang AV cable with 24K gold-plated terminals, effectively put an end to alleviate the \"aging\" of the generation.
How to choose the best rectangular box length width height
The day before yesterday I was asked – after VB know how to choose the best rectangular box length, width, high?
In car audio conversion in double bass in the trunk after modification or audition with the majority of the rectangular box more and more widespread use of audio enthusiasts, we know whether it is open or closed container boxes designed to get VB (box volume) After the selection box dimensions (length, width, height) usually use design software is all one way. Software design of the box there will be minimal strong normal-frequency, but not necessarily beautiful and decent appearance. And unconditional, or the majority of audio speaker manufacturers design modification enthusiasts, and not the technology described in the article refer to the so-called “golden section” Design of the box more practical, affordable … ….
But through the car stereo conversion constant practice, it has long found a “golden” ratio or “Golden” split rate to determine the proportion or ratio box with the ideal ratio of 0.618 for size, integer size in the application of the case, for example, 6 unit length (depth), 10 units of width and height of 16 units, the depth and width ratio of 6:10 = 0.6, while the width and height ratio is 10:16 = 0.625 These final size and aspect ratio the ideal value of 0.618 is quite close, because the ratio of the approximate size can not be selected to enhance the sharp resonance of the public inside the normal-frequency, so this ratio is, the speaker box to confirm that the manufacturer can produce the best sound quality Speaker size ratio … …. there is a better explanation we continued to talk about!
is recommended to install treble Mazda CX-7 sound system evaluation
Sometimes, a small number does not mean shabby, but can exchange for a natural beauty;
In today s 200,000 yuan level cars are generally configured dvd host, 6 or 8 speaker of the era, the price of 288,000 yuan, but only
cd cx-7 host plus four speakers, this is the concept? I believe that many consumers are too Depot selling cars is not sincere, but when
you actually heard the sounds of this system, you will find audio of the speaker should in fact not much, but as long as the proper
equipment selection and configuration, 4 will be able to play back the sound of nature!
Mazda cx-7 is a “sport utility” property clear of the car, the exterior and interior have revealed blood throughout the design, except
the sound was like a simple configuration of cold water, putting water in their attraction on this car , which may be depot that
consumers purchase cx-7, the focus will be on the Dodo and personality, not sound right! cx-7 audio configuration more simple?
1 set with 3.5mm headphone-style external signal input terminal 6 disc cd, wav, mp3 host, four 5 × 7 英寸 split single basin, described
by experts as sound: “to be removed to install this stuff in 10 million level of domestic car ride pretty lining! “The proposed depot sold
in Taiwan may wish to draw the cx-7, to configure it a bose audio system!
In with the eye cx-7 s sound configuration, the experts conclusions seem backward “too simple” side, but when we actually listen to
it with ears the sound performance of the experts but gave it a good rating, that the depot in sound configuration or a motive, but
did not choose to use accumulated amount of equipment to Zhongxinggongyue, why? Natural sound quality, stability is the answer,
and achievements of this reversal of the conditions of disadvantage, first, that cx-7 on the door, there is even a large one-piece
speaker mount the plastic film, can completely seal the door of the holes to form a similar closed speakers, good sound favorable
display space, but unlike most car just close the door hole with plastic waterproof test. Followed by the cx-7 with a similar monomer to
play full-range sound, unlike the general speaker package with more than two full-range single reconstruction, but more frequency,
phase, single impact sound positioning and other variables. The sound is also fortunate to senior professionals, the Hong Kong Science
and Technology International, Managing Director of WLS Mr. Li Zhihao cx-7 with the appreciation of sound, this sound system is the
following dialogue.
Pan permanent: and Mr. Li (Li Zhihao) you have done a lot of the original car audio systems tasting, happy is that we in the process of
tasting sound good to develop a certain understanding. After listening to this Mazda, can you give me this kind of tasting experience
it?
Li Zhihao: fortunate enough to participate in this part I actually gain a lot of activities to learn more about some of the first wife of the
different levels of car audio, as this Mazda, audio configuration is unique, so I Qijing: listen to the song 2009 Hong Kong Advanced
audio-visual Exhibition “Sounds Selected SACD” audition Tiandie the first seven of the Shenandoah, replay Chu in this sound system to
smooth the effect of people feel very strong sense of timbre pure, original car stereo to listen to the kind of uncomfortable feeling in
the This does not, tone, I think I will this Mazda spoke highly of.
Pan permanent: listening, many enthusiasts often say Naiting degree does the car sound system in the performance of Chu
excellence, more rare is this car Mazda s original sound system in the power amplifier output Chu is also just right, when the sound
system high-power high-volume, the control of the speaker is still Chu color. Looking at these systems before the sound field only
install a pair of full range speaker unit, Li Sheng sound field performance of this design to your ideas on to the next.
Li Zhihao: Many of the sound field before the first wife of vehicles using two-way speaker crossover single design, the characteristics of
the sound field so high, a good high-frequency bandwidth, dynamic range greater. This is the original Mazda car with full-band
approach is to reduce the speaker crossover benefits arising from the physical deficiencies, but the full-range speakers in the car s
performance Chu of the sound field is low, but also by the lack of flu after the fact.
Pan permanent: the sound field is low, and on the list. Ho brother is right, I set the host to adjust the front and rear sound field, the
attempt to sound field forward, but unfortunately the sound field becomes front, but unfortunately the overall sound quality and thin,
and Lee students, I am in this for the sound quality pursuit of the owners of certain higher your friends to demand improvements to
the recipe.
Li Zhihao: the original car s dashboard is actually reserved for the first sound field two-way design speaker position, want a friend
suggested a simple modification of the original car s speakers, based on the installation of alt of the speaker unit, so that the original
car s high-frequency less have a better upgrade. Before the proposal conditionally, of course, dress sets of 8-inch acoustic frequency
speaker packages, the installation of the amplifier with a push, with 8 of the suit the style of the original car, the other advantage is
saved plus the subwoofer to be part of.
Car Speakers Detailed performance and characteristics
Some people think that the speakers and audio-speaker-24/”>car audio speakers exactly the same appliance, this view is not correct, the frequency
response, power, impedance, sensitivity, etc. basically the same, but in the making process, the use of materials, structures, etc. with
special the design. By understanding the performance of car audio speaker, after the structure and characteristics, can know what is
different between them.
Used in different environments
1, temperature: the speaker in the room using appliances small temperature difference, in a car outside of work, change the
temperature difference between hot and cold climate with a large, so the structure can not be anti-aging temperature deformation.
2, anti-moisture: car in the rain, taking the water section, should be wet when the car wash, so cars with loudspeakers to moisture,
many now use synthetic material cone.
3, anti-dust: the speaker in the room using appliances less dust, and dust inside the car more than required to prevent the voice coil
dust cover friction noise.
4, vibration: car speaker car at any time by the movement of the shock and vibration, is designed to be strong can not loose.
5 Noise: Consider noise and reflection of the car, use of different materials, using a variety of different design approach to offset the
noise.
6, car speaker installation location is limited to listening to the sound field positioning, pitch angle designs.
7, the impedance will be small: car power supply voltage is low, in order to get big power, the speaker s impedance are small, there is
more use of 3.2Ω and 4Ω or 2Ω 1Ω, using a dual voice coil, parallel way up to 2Ω or less This method is rarely used home stereo.
From the CD player you want to appreciate the effect of clear, wide range of natural music, which ultimately, high-quality speakers.
Speaker s frequency response is from low to high range of accurate sound renewable, high-quality speakers can handle special power
level. In addition to continuous power handling capabilities, but also regeneration of music without distortion of the transient peak,
this CD, like the digital audio is especially important. Car speaker manufacturing process there is a very important point, that is,
environmental and traffic on the road, the quality of the speaker test, design right the best speaker system to confirm the installation
of speakers in a variety of specific performance under the conditions and audio distribution. The following describes the structure and
characteristics of the car speakers.
Automotive original tape, most speakers use cone or double cone speakers (in the middle of a single basin seeks to add a small cone),
speaker frequency response of this narrow, long time cone is easy to embrittlement, now little used. CD, why not dress the original
car speakers, car speakers because the original power of small, high sensitivity, high output power facelift CD player, so prone to
distortion. Treble is poor, the original car stereo is a tape machine, it can not match the high treble speaker, treble good tape if the
background noise will be shown. Facelift CD audio, be sure to change out the original car speaker, speaker facelift treble and strong
performance, this way to reflect the characteristics of the CD.
Limited to the car speaker installation issues, high, medium, hard and home audio subwoofer is installed in the same plane, the usual
method is to use hybrid, the high, middle, bass fixed in a cone frame, the majority of the use of Coaxial, there is also bridged
structure. According to automotive internal structure, better positioning of the sound field, using the modular separation of the treble
and bass, with a passive crossover connected. In order to obtain good power and whole-tone-type dynamic characteristics, does not
have to use large-size speakers, using box-type speakers, half-way box tetrameter tetrameter and passive radiant way. Because the
small size of the car, but also access to a wide frequency, the speaker is designed oval as: 6 × 9-inch, 5 × 7-inch, 4 × 6 inch.
Tweeter: use more titanium dome tweeter NdFeB, NdFeB silk dome tweeter, neodymium iron boron magnets and magnetic small
powerful film with pure silk soft sound vibration mode, this tweeter sound natural and full , treble, clear and legible, there is also pure
carbon dome tweeter, dome-type styrene rubber coated polyester tweeter, etc., more than treble in the car dashboard installed on
both sides and both sides of the door at the top, especially bearing free rotation Select the response direction. Tweeter used more
often and the size of 1 inch 2 inch. Installation forms a surface-type and mosaic.
Bass speaker: multi-purpose polypropylene cone material, which is made of high strength poly-propylene thermoplastic polypropylene
resin has excellent moisture resistance, oil resistance and heat resistance of anti-soluble and very remarkable, it is very tough, that is
bear power burst, but also stand by the large volume, but also has high sensitivity, can by the appropriate damping effect, show clear
and fine vocal music charm, more use of carbon-iron pots blending polypropylene film. Use heat-resistant voice coil sub-bromide is a
good polyamide voice coil bobbin for high power loudspeaker management material. Basin side of the skin side with natural rubber to
prevent deformities and fatigue. Application of more mid-range speaker size is 4 inch, 5 inch, 6 inch, 6.5 inch, with coaxial and split.
Subwoofer: car driving in the car interior noise, and road conditions often make the bass structure has been weakened, install the
appropriate high-performance subwoofer can be the ideal solution to this problem, so as to maintain the natural tonal balance and
sound rich depth, breadth , and the clear pure, subwoofer and refined using high-strength aluminum frames, gold-plated speaker
terminals to enhance overall performance, with ultra-superior conductivity and prevent oxidation corrosion, special bulletproof tympanic
membrane strengthening, epoxy coated pressure the cone, dual damper ventilation and longer pole, extending yoke and large
strontium magnet alloys. Subwoofer applications more size 8-inch, 10 inch, 12 inch, 15 inch, 18 inch.
Use the subwoofer design, useful box, drum, also use the trunk as an enclosed vehicle, designed to reproduce the rich bass and large
sound pressure level (SPL). However, not everyone has a car speaker or placed where there is enough money to custom speakers,
the United States KICKER freeair enthusiast uniquely designed subwoofer, the speakers do not need to be able to produce a strong
bass sound effects, easy to install cost less, if you also use a KICKER amplifier, coupled with an active crossover module can produce a
sound feeling. Now KICKER has produced square SOLO-BARICL7 type subwoofer, the subwoofer features the largest full use of
cabinet space, so that the sound pressure increase.
If you choose to listen to the sound quality of the sound system, on the choice of KICKER SOLO-BARIC subwoofer, sound real and
lingers. If you choose to listen to the sound pressure “bomb” on the choice of the United States RORK FORD subwoofer, the sound
powerful.
Select the speaker, first consider your choice of sound system is one of those types (sound or “bomb”), followed by the speaker to
consider matching (power, frequency response, impedance, etc.), have an overall co-ordination, so that equipment to maximize the
advantage.
Basic package: with the host s own power amplifier (per channel 50W), the speaker can generally choose maximum power 120-150W.
car audio conversion to give you a million reasons
The following passage quoted from Liao Jianhua brilliant teacher comments: Hefei market can support 10 professional car audio shop
conversion, why can not you there?
“The only reasonable answer is Hefei Hefei local car audio store continuously modified pie bigger and bigger, and only a big cake to
feed more stores, all stores in order to live more moisture.”
This comment I have mixed feelings, as the car audio industry in Hefei part, deeply long way to go. Shops and more fear, but more
and more felt, car audio conversion marketing obstacle is the owner of the concept (especially for the early development of the
store), so the germination of “car audio conversion, to give you a million reasons,” this proposition.
The world is guided by the subject and object, I dominate my senses, and their vision for the future dream car might as well have
today …… by audio conversion (upgrade) and enhanced with the fun of it, not because the audio conversion vehicle level determines
the meaning of its existence.
Xiao Wu initiate tribal Tianyin, please express their views, padded audio conversion a million reasons, in fact, even if there is enough
to power 100, the more welcome that it will not change the sound of reason, as long as the idea is true, are worth considering .
Hovering in the change and make more do not change, change to what extent the confused riders, more rational to face this audio
conversion.
More than once heard the owner say: but not a good car, commuting to open to open, change what sound, what the speaker
upgrade, what noise, not that necessary … if you buy a Department of luxury cars, it should be a good change it … owners pass
information: that is clearly a good horse with a good saddle. Even own sound pretty interested, he would think so, of course, here is
the majority owner. Players may discuss the scope of the (often with modified equipment worth more than the prices of things
happen oh).
Careful analysis, this passive concept generation, is the inertia of thinking at play: that since it is not a good car, noise, and also
opened a few years, why should I waste money. In fact, they often overlook an important factor: stereo upgrade is used to enhance
the owners converted the fun of driving and enjoy a good car audio, can alleviate the pressure of work, the mood relaxed. Than the
fitness and the park, do not specifically take time to experience, but take the time and space to treat yourself like fuel line or a red
light, waiting for the wife lounged intermittent painting makeup, traffic jams suck points seconds, minutes and seconds, high speed
easy to fall asleep, and so on. These make you uncomfortable living fragments, so long as to music, to enjoy the wonderful sound you
will become one of joy. If the normal driving time count, the happy unknowingly have a multiplier effect.
Above should be established on the basis of a good car audio, (if the speaker is very general, the doors do not any noise, feeling
slightly turbid, slightly smaller can not hear the details, and then mixed with the noise resonance point of the door, then the real fun
can not even talk, this time to shut up sound, or listen to radio traffic, a more realistic understanding of where the traffic jams)
car audio wire tips The first is a good safety wire requirements
Wire for the emergency vehicle is very sound, and sophisticated requirements of the first wire is safe, followed by a good anti-
interference, attenuation. audio cables and signal lines and power lines, including two major categories.
Signal lines: requirement of a good anti-interference, can reduce the signal attenuation, Bingge delicate, the joints to prevent
oxidation. Some of the top signal line often using special alloy materials, card-ring plug and plug gold plated to prevent oxidation. For
example, the United States monster (monster) brand wire in the audio enthusiasts is Tai Fu Ding Ding.
Power cord: current and voltage requirements of stability, impedance, current attenuation. Selection and power supply cable for
power is often a large current is also large, need to select the thick wire. High purity materials commonly used pure metal wire, a
senior major and enthusiasts will use sterling silver wire. Wrap the power cord insulation material in addition to insulation, but also to
high temperature.
