Description

It has a large heat sink and it never shutdowns from overheating. The line level input connector is a standard 1/8" stereo connector, the power and speaker connections use CMM5-2 PCB screw down terminals. . The screw terminals are typical for these types of bare amps and are a little weak (so don't over tighten, or solder on some wires). This is a amplifier. The board design is quite simple as most of the work is done by the ST Microelectronics 7377 integrated circuit
