Note .Output short circuit .2.Output DC bias speaker .3.Over temperature : 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.Specifications:Power supply: dual DC power supply ± 58-± 70VThe rated output power: 500W (± 65V power supply, 4 ohm load, distortion 10%)Efficiency:> = 90%SNR: 90dBThe total harmonic distortion:380W (± 65 power 4 ohm speaker, distortion <0.1%)280W (± 65 power 8 ohm speaker, distortion <0.1%)
