This is a digitally controlled stereo electronic audio volume board with gorgeous appearance. It features a mature volume adjustable module and external power and signal output connector. Several wiring methods such as 3.5 mm Socket (Default) facilitate connection. Analog and digital section powers are used independently to minimize the interference. Excellent heat dissipation eliminates the need for an extra heatsink. Over temperature, over current protection and power supply anti-reverse protection are included to extend its longevity of the board.
