Description
Description
Stereo TDA20x0 based amplifier with sub. Power output will depend on which chip is used from 20W to 50 per channel. Will also depend on voltage applied to the board. Will require minimal of 24V or ideally 36V center tapped with minimal 18V positive and negative rails. The board was meant to be stacked on top of the 4ch mixer board but it can also be used as stand alone amplifier. All voltage rectification is on board and has connectors for interconnecting into the mixer board.
