Hall Research AMP-7040 40W Audio Amplifier for 70V or 100V Systems with RS-232 Control

AMP-7040 is a 40 Watt power amplifier (CIass D) with outputs capable of driving 70V or 100V systems (user selectable). It has 2 stereo inputs (3.5mm jack for line in and 2 RCAs for L&R), 1 digital input, and 1 balanced MIC input. The microphone input audio is mixed with one of the inputs (RCA, 3.5mm, or SPDIF). User can select which input the microphone is mixed with using a button on the front panel, using RS-232 command, or using the optional IR remote (sold separately).

The flexible design of the AMP-7040 allows the use of dynamic or condenser microphones with fully adjustable control options including audio ducking function, EQ control, MIC mixer and more, all of which are controllable via RS-232.

The AMP-7040 is a perfect for classrooms, meeting rooms, boardrooms, sports bars, and more.
