2X100 Watt Class-D Audio Amplifier Board

Powered by any DC voltage from 10V to 32V, this high efficiency amplifier board is capable of outputting up to 100W per channel. Volume control can also be done via on-board DIP switches. Besides, this board can be used to drive 4Ω or 8Ω passive speakers.In addition, auto fan control function is utilized so that the cooling fun will self-adjust its rotating speed when the temperature of chips is too high, ensuring the normal working of the chips, and will automatically shutdown when the temperature of chips keeps low, ensuring the fun’s own long service life.
