Features:

1.Output short circuit protection.
2.Output DC bias protection speaker protection.
3.Over temperature protection: the output will turned off when the temperature of the heat sink FET is higher than 100 °C.

4.This is a pure power amplifier board, whose sensitivity of the input signal of 1.5V rms, if your input signal voltage can't reach this value, recommend add preamp.

5.Mono channel,for 2.0 channel need bid two.
