Description: Assembled Mono 60W PASS A5 Pure Class A Power Amplifier Board Base On Pass Labs Aleph 5 Amp This amp board adopts the famous Pass Labs Aleph 5 single-ended class A power amp circuit, the original machine more than 20,000 US dollars! The circuit board wiring is reasonable! use Hiend the Resistors. the sound is transparent and clear, the sound bottom is clean and neat, the level is good, the low frequency dives well, and the high frequency has penetrating power. The power Transistor adopts the new IRFP250 high-power field effect Transistor of the American IRF company, 6pcs per channel, and the static current of each channel reaches 2A! Each channel is powered by an independent power supply circuit, which is composed of 12pcs Nover Audio grade Gold letter 10000U/50V electrolytics and imported non-inductive resistors for CRC filtering. This amplifier with perfect speaker protection circuit. it can protect your expensive speaker from the impact sound when power on /off. Works votage: AC28V-0-AC28V (25V-28V are all ok) Transformer power: recommend about 300W or more PCB Size: 305mm *152mm *45mm (L*W*H) with the Rectifier bridge. the width about 178mm Output power: 60W /8ohm, 90W /4 ohm ● Cain 20dB ● Freq Response -0.5dB at 2 Hz,-2 dB at 100KHz ● Distortion(1KHz) 1% @ 60 watts,8 ohms 3% @ 90 watts,4 ohms ● Input lmpedance 10 Kohm unbalanced 25 Kohm balanced differential ● Damping factor : 50 nominal ● Output Noise: 600uV unweighted ● DC offset: < 100 mv ● Support signal input: RCA single-ended input or XLR balanced input Note: this list price is for 1pcs Mono amplifier board. and not include the heatsink!!! to built a stereo amplifier will need buy 2 of this board. If you want buy the amp board with the heatsink. please contact us!!! The temperature of single-ended class A is very high (2A static current per channel!) Please do not test it without installing a radiator or a small radiator!
