Reference PASS Circuit A3 30W * 2 Pure Class A Amplifier

Reference PASS Circuit A3 30W * 2 Pure Class A Amplifier 

*PASS A3 is suitable for modern household HIFI, 30W@4 Ohm's Gold Class A power provides excellent vocal performance in listening to music (within 20 square meters), pushing bookshelves and floor speakers of 88DB or above,

*PA3 is a complete machine oriented design solution with a good power foundation, which will make the background of the sound quiet and the details can be expressed.

*PA3 achieves low noise through the use of customized high-power ring transformers paired with capacitor arrays and CRC format filtering. PASS A3 does not have a midpoint adjustable function, and the entire system relies on precise matching of input and power tubes to avoid overheating. The entire system is surprisingly quiet. (PS: Some machines only have a midpoint voltage of 0.3MV, which is very rare), with protection function.

*The biggest highlight is no low noise, very quiet, very mellow. The mid frequency is neither thick nor thin, and the high frequency is not noisy, not dark, and low frequency. Generally, the low frequency of the PASS series has a faint sadness, and it can also dive, which surprised me a bit.

*Size: 430 * 310 * 120MM high (excluding protruding parts)

*The application of filter capacitor array, ultra-low power supply internal resistance, and 16 ELNA-RJD electrolytic capacitors with low impedance, long lifespan, and high temperature (105 degrees) can achieve a filtering capacity of 89600 uF per channel, and the effect is amazing.

*High sensitivity (0.3V) protection circuit ensures that your beloved unit will not be harmed.

*The NIGECON KZ capacitor and Weishi Sifeni output resistor, ordered specifically for the needs of school sound, have a noble and smooth sound like silk.
