Wohler AMP1A-LP Analog Audio Monitor Panel
This stereo audio monitor provides self-powered, full-fidelity stereo monitoring of analog audio in the smallest rack space possible (1U) with two inputs on balanced XLR inputs and unbalanced RCA inputs with two 10-segment tri-color LED bargraph level meters.
A pair of balanced XLR connectors output the selected audio source for connection to downstream equipment.
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 front panel also features Wohler's' proprietary three-LED stereo phase indication feature, volume control, balance pot, power indication LED, and stereo headphone output.
