The AMP-1 Digital series of audio monitors provides self-powered, full-fidelity stereo monitoring in the smallest rack space possible. All models in the AMP1 Digital series contain four high performance transducers driven by three power amplifiers: two amplifier/driver combinations handle midrange and high frequency information in stereo, while the third center channel reproduces information below the 500 Hz crossover point.

All AMP1 Digital models come equipped with a ganged stereo volume control and balance pot, power indication LED, and headphone output. Output limiter circuits are incorporated to protect the speakers, and extensive magnetic shielding allows placement immediately adjacent to video monitors with no color impurities.

The AMP1-SDA model features an SDI input and loop-through on BNC connectors, an AES input on an unbalanced BNC connector,an AES output (converted from the SDI input) on a BNC connector, analog inputs on two balanced XLR connectors, and a stereo analog output of the selected source on two XLR connectors. Toggle switches on the front panel allow selection of subgroup 1or 2(Channel 1/2 or 3/4) of the SDI input, SDI or AES input sources, and a choice of the selected digital source or the analog source inputs. Two red LEDs indicate the presence and error status of the selected AES and/or SDI signals entering the unit.

Two high-resolution 26-segment tri-color LED bargraph level meters display the audio levels for the left and right selected sources.Wohlers proprietary three-LED stereo phase indication feature allows monitoring of phase relationships of the selected stereo inputs.
