R.C. Precision Stereo amplifier 2x20W RMS class D (ABI-MM4001S40)

The 2x20W RMS stereo Class D audio power amplifier provides Class AB amplifier performance with Class D efficiency. This device works from a single 14VDC or battery supply, has click-and-pop suppression as well as short-circuit and thermal protection.
The amplifier has a direct line level audio input on a 3,5mm stereo jack on the connector side of the module, and an override stereo jack input on the other side of the module. Loudspeaker outputs are on industrial grade pluggable connectors.
The gain and mute of the amplifier can be controlled either by an external volume control potentiometer (ABI-MM1005Sxx or ABI-MM1045Sxx) or by a 0-10V automation control signal from any of the popular brands / standards.

Required power supply:  ABI-PS4014S45 (desktop version) or ABI-PS3514S45 (DIN rail version
