Champ Audio Amplifier Kit with Pre Amplifier (01/13)

Assembly Required

The Champion Audio Amplifier Kit with Pre-Amplifier Refer: Silicon Chip Magazine January 2013 An amplifier and pre-amplifier combination for all those general-purpose audio projects. It uses the AN7511 audio IC to deliver 2W music power into 8 ohms from a 9 to 12V supply. Features low distortion, two inputs (mixed 1:1), over-temperature protection (auto-limiting), Mute and standby control. Pre-amplifier is also suitable for microphones and electric guitars, and can be separated from the amplifier for individual use. Kit supplied with silk-screened PCB, heatsink and PCB mount components.
