The AMP1A-SUM6-RD audio monitor provides self-powered, full-fidelity stereo monitoring of analog audio in the smallest rack space possible (1U) with a mounted depth of just 6.5", six audio input channels on a DB25 connector, and six individual volume controls.

Channels 1/2/3 are summed to the left speaker and channels 4/5/6 are summed to the right speaker.

Each of the six channels may be individually adjusted for volume to allow mixing of the overall output.

The audio amplifier section features five high performance transducers driven by three power amplifiers: two amplifier/driver combinations handle midrange and high frequency information in stereo (left and right speakers), while the third center channel reproduces information below the 500 Hz crossover point (woofer speaker).

Output limiter circuits are incorporated to protect the speakers, and extensive magnetic shielding allows placement immediately adjacent to magnetically sensitive equipment, such as video monitors.

The unit features six input channel volume controls, power indication LED, and headphone output.
