Feature

●It adopts TPA6120A2, front stage reinforcement OP275 operational amplifier
●Be careful? The voltage on the board has been debug before delivery? There is no need to adjust the adjustable resistance of the two positive and negative power supplies? When you really need to adjust? Need to unplug the two op amp chips and the two jumper caps first? In order not to damage the operational amplifier due to asymmetric voltage during regulation? ?
●Operating voltage: 12V-16V
●Board size: 100mm x 100mm
