2CH PASS A5 Audiophile FET PASS Aleph-5 Pure Class A Power Amplifier PCB 60W+60W

Description: Introduction: A5 is an improved circuit design of PASS A3. The HI-END material is well received by Audiophile. Refer to the PASS A5 circuit of the famous U.S Audiophile machine. The sound style is similar to that of A3, but the power of A5 is larger. It has a 8 ohm speaker load. The output power can be up to 60W at a time, and the output can reach up to 90W at a 4 ohm speaker load. The sound field is wide, the low frequency is strong, and the driving force is better than A3. It is one of the excellent circuit choices for DIY single-ended pure A power amplifier. Adopt HI-END double-sided immersion copper PCB, with large area copper traces on the top, bottom and bottom, and can push tin, which is very stable when large current passes. Two-channel mirroring design, the circuit is fine to every solder The board, every line is carefully designed, and it is all the patience of the designer! Parameter: ● Input voltage: DC: +/-35V (Transformer power is not less than 400W/Per channel) ● Output power: 60W /8ohm, 90W /4 ohm ● Channel:2 channel ● THD: 1KHz 1%, 0.003% /5W 8 ohm ● Input impedance: 18k ohm RCA, 10k ohm XLR ● Output noise: <300uV Unweighted 20--20kHz ● Dynamic range: 140dB ● Gain: 20dB ● Support signal input: RCA single-ended input or XLR balanced input ● PCB size: 294mm * 85mm NOTE 1: PASS A5 is a pure Class A power amplifier, it is very hot, so the heat sink requirements are particularly high, please do not turn on the power without the heat sink installed, otherwise the FET tube will be burned immediately after the power is turned on. The weight of the heat sink is not less than 5KG per channel. NOTE 2: This is bare PCB, all parts need to be matched and installed by yourself.
