P-3548D Digital Power Amplifier

P-3548D Digital Power Amplifier

P-3548D

The P-3548D Power Amplifier delivers 480 W power output. It is so designed that it's power ON/OFF can be remotely controlled when used in conjunction with A-3500/A-3500 Series mixer amplifier (option). The P-3548D can also be used as a stand-alone amplifier. It employs a PFC circuit.
