Which brand of capacitor is best to use on the power amplifier

There is no best, only the most desirable. The price is not necessarily good, but it feels good. Don't get tangled.

1. China XICON

Relatively inexpensive capacitors, made of polypropylene treated using modern metal deposition processes. The sound is bright and the dynamics are fairly neutral. Its bright timbre due to excessive high frequencies is known as "fast" in Asia (in order not to cause confusion, it should be made clear that "fast" in Europe and the United States usually means good dynamics).

2. Weimar wima

WM WIMA capacitors are characterized by fast speed, low loss, natural balance of sound quality, and cold timbre, which are suitable for a variety of listening requirements. When using Weimar WIMA condenser, the timbre is clearer, the high frequency is crystal clear, the middle and high frequency details are more, and the level is also clear, which can be described as brilliant and brilliant in the middle and high frequency. Many enthusiasts generally like to use WM Wima capacitors in the coupling circuit, which will have a greater impact on the timbre orientation, especially highlighting the details of the mid and high frequencies.

3. The characteristics of Eroero are similar to those of WM Wima, the feedback end in the power amplifier circuit is a direct capacitance to the ground, it has a large insulation resistance, small dielectric loss, and neutral timbre. The sound of ROE is very similar to that of ROE, a well-known brand of electrolytic capacitors, the difference is that ROE is more accurate, but ERO reflects a faint emotional factor.

4. Siemens

This brand of electrolytic capacitors and film capacitors are happy to be used by the German Hi End famous manufacturer MBL, and the sound performance is extremely good, especially the middle frequency is very loose and wide and full, ** sense is excellent, but the speed is slow, the high and low bass are not good, especially the treble is not very good, but the strength should not be underestimated.

5. Philips

Philips Philips film capacitors are not as good as its electrolytic capacitors, and Philips Philips electrolytic capacitors are quite attractive when used as filter capacitors, such as their elasticity and strength are superior. However, the advantages of film capacitors are obviously not so obvious. Philips Philips' film capacitors are generally neutral, the capacitors are fast and powerful, the sound is refreshing, the timbre is delicate, transparent, atmospheric, and has the luxury of European capacitors, and the low-frequency dive and density are very good.

I'm still a little confused, can you be more detailed?

Hello, I am glad to serve you and give you the following answer: Nichicon is a Japanese capacitor manufacturer, its capacitors have good voltage resistance, can provide higher voltage and current, and thus improve the efficiency of power amplifiers. :p Anasonic is a Japanese capacitor manufacturer, its capacitors have good withstand voltage performance, which can provide higher voltage and current, thereby improving the efficiency of power amplifiers.

In addition, it has good anti-vibration performance, which can effectively reduce noise. : RubyCon is a Japanese manufacturer of capacitors, its capacitors have good withstand voltage performance, can provide higher voltage and current, round to improve the efficiency of power amplifiers. In addition, it has good vibration resistance, which can effectively reduce noise, and has good heat resistance, which can improve the reliability of the power amplifier.

Steps to solve the problem of amplifier filter capacitance:1First, determine the power requirements of the amplifier, as well as the voltage and capacity requirements of the filter capacitors.

2.Then, depending on the power requirements of the amplifier, select the appropriate cavity trap filter capacitor, such as Nichicon, Panasonic or RubyCon. 3.

Finally, install the filter capacitor and make sure that the capacitor is wired correctly to ensure the proper operation of the amplifier. Personal tip: When selecting a filter capacitor, it is necessary to select the appropriate filter capacitor according to the power requirements of the amplifier, as well as the voltage and capacity requirements of the capacitor, to ensure the normal operation of the amplifier.

Role 1After the AC transformer rectification, the voltage changes in height and low, and the ups and downs are 50 times or 100 times a second, and the horn buzzes after the direct power amplifier, which is the AC sound, which should be suppressed and overcome. After connecting the capacitor, the power supply voltage is high to charge the capacitor, and when the voltage is low, the capacitor discharges outward to increase the voltage, which makes the power supply voltage stable, and the larger the capacitor, the more stable the voltage.

Role 2Provides instantaneous high current, improves low-frequency response, and appears powerful at low frequencies. This is especially noticeable when the power supply is small. If it is used in battery-powered speakers, the only use is this. Battery power can be reduced or eliminated.

In the figure, which four capacitors also have midpoint capacitors, which are equivalent to power supplies.

First-line manufacturers: Japan's Sanyo Sanyo (top first-line manufacturers with excellent quality), Nippon Chemical Nippon Chemi-Con is also called Jiameigong Jiameigong (first-line factories with excellent quality**slightly lower).

Second-tier manufacturers: Nichicon is also called sapphire (second-tier manufacturers have medium and low quality), Fujitsu Fujitsu has been acquired by Nikon (the early product production is small and the performance is good, and the later products are consistent with Nikon), ruby Ruby Rubycon (the brilliance of liquid is no longer there, and it is a rare brand of solid-state capacitors).

Third-tier manufacturers: Skywell (mainly using daily chemical technology organic semiconductor capacitors), Taiwan Lelon OCR (blue top uses daily chemical technology to produce semiconductors and polymers at the same time), Taiwan Wanyu Samxon (red top uses Fujitsu technology), APAQ Yubang (purple top logo is a dot in the middle of a circle), Kingsoft Electronics ELITE (dark blue top C inside an S), Taiwan Feicheng FCE (powder top uses Japanese pine high molecular technology), South Korea SAMHWA (green top).

Fourth-tier manufacturers: some nameless mainland Taiwan manufacturers, the quality is uneven, and the quality is low.

Tweeters generally need to divide the frequency, and the simplest is to string in a stepless capacitor for frequency division.

The commonly used crossover capacitor is microfar, and when this capacitor is added, the treble sound will become smaller. If you feel that the treble is still high, try to change the crossover capacitor capacity (try to change to a smaller one, or you can string in another one, the capacitor series capacity is reduced, and do not add resistance). But this method, the pre-fight is the easiest frequency division, and the effect is not too good.

If you want to have a better effect, you can buy a finished two-way crossover with an inductance coil (it used to be very good in the electronic market, but now I don't know the draft silver lead), and if you have hands-on ability, you can also find some information for reference and make your own two-way divider.

What resistance or capacitor does the midrange speaker need to add?

The midrange horn needs to add a small resistor and a large capacitor. This can not only filter the wave, but also not produce impedance and capacitive reactance of the IF signal. Of course, it can also be left unconnected, and it will not have a bad effect on the power amplifier.

The midrange speaker, the tweeter and the woofer form the horn of the car audio. The frequency response range of the midrange speaker is between 256 and 2048 Hz. Among them, 256-512Hz is powerful when listening; 512-1024Hz listening feeling is bright; 1024-2048Hz listening feeling is translucent.

The vocals are realistic, the timbre is clean, powerful, and rhythmic. The woofer is generally not used alone, but with the tweeter and the midrange speaker to form a sound system, the sound is vibrating, the frequency is low, so that the human ear resonates and shocks, and the key is good to be used in KTV, bars, stages and other wide places. <>
