1.Remove the old amplifier without remote control function, so that it can add multi-channel audio source input selection function and volume remote control function.
2. can achieve multi-function audio source switching + volume control function, this system is equipped with automatic volume return to zero.
3. Used as an external volume controller. For example, some TV or DAC decoder output cannot adjust the volume. Joining this system can easily solve the problem of volume control.
4.Pure power amplifier and other equipment without volume control function added to this set to realize sound control function
