Operating voltage range :8.5-14v, output power: 10W*2 (8 ohms) or 15W*2 (4 ohms).

The unit uses 12V DC power supply, current over 3A.

 

1.6mm thick sheet using double-sided PCB, 2.0 oz copper thickness, HASL whole process to ensure the size of the current through the good performance.

 
Component selection: new and original TA2024, chip resistors, chip capacitors, the main filter capacitors are brand ELNA, is mostly non-polar capacitor top WIMA, including the use of coupling capacitors WIMA capacitors 1.8UF. 
  Resistance selection Rings metal resistance, the main circuit of the use of accuracy +-1% metal film resistors rings, ensure the machine a good signal to noise ratio.

 

The amplifier increases C1237 delay protection circuit can be eliminated to open, shut down the impact of sound, a fully enclosed double relay, the relay contacts to effectively prevent oxidation caused by poor contact.

Increase the output zero circuit can adjust the output to 0V DC bias to reduce distortion and protect speakers.
