Description

Using the HDAM-SA module topology, the input is a very nice Diamond Buffer circuit, also called "diamond (diamond) expansion circuit", and the I/V mirror circuit is used between the voltage levels, and the matching characteristics before and after are excellent. The feedback form is current negative feedback, which has excellent load control ability. In addition, a midpoint servo circuit and a more complete speaker protection circuit are added. The intermediate voltage is very stable and is basically a few millivolts. Power supply range: main voltage dual DC 35~55V (dual DC 45V is recommended); speaker protection power supply single AC 12~17V (single AC 12V is recommended). PCB size: 167*83MM Tips: We also have finished boards and complete kits for sale, if you need them, please contact us. Thanks! ! ! Package list: 1 pair × Bare PCB
