The VitBest AM-AM140-HZ is a 40 Watt power amplifier (Class-D) with output alternatively at 70V or 100V. It has 2 stereo inputs (1x3.5mm jack for line in, 2xRCA for L&R), 1 digital input & 1 balanced MIC. The AM-AM140-HZ is integrated with powerful functions, including ducking function, EQ control, MIC mixer etc., and MIC input supports 3 levels with condenser MIC, dynamic MIC & line audio input. As for power amplifier we have normally voltages at 70V and 100V for different countries, but the amplifier is designed to integrate with both voltages to meet different requirements.
