● Recommended voltage AC dual 22V

● PCB size: 121×64mm

● Dual channel 100W 4R, can be bridged to 200W 8R mono output. Comes with bridging.

Equipped with filter capacitors imported from Japan. Two 35V4700UF.

25A high current original rectifier bridge.

Equipped with special inductors for original Japanese digital power amplifiers, fully shielded OFC leads.

Original relay protection circuit. It adopts Japan Panasonic M original coupling input capacitor MKP 3.3UF.

Refer to the picture, the radiator is installed, for reference only:

Wiring diagram, reference:

● Wiring diagram, you can click to save as a clear large diagram.

● After installation, please set the jumper to the non-silent mode. The relay will be closed.

● Adjust the adjustable resistance so that the midpoint voltage (DC voltage between OUT and GND) of the two channels is less than 10MV.

● If it is set to bridge mode, the midpoint voltage needs to be re-adjusted.

Performance test chart:

Actual measurement:

Carrier working state, before output filter.

Output after the filter:

Work test:

Half-bridge dual-channel mode Input signal 500MV Output 10V *2

BTL full bridge mode Input signal 500MV Output signal 20V *1

(Warning: The dual trace probes of the oscilloscope share the same ground, so in the test full bridge mode, the oscilloscope cannot measure the input and output signals at the same time)
