Wohler HRS-1S

1U half-rack Analog 2-chan audio monitor.

The HRS-1S audio monitor provides self-powered, fidelity monitoring in the very smallest rack space possible.

The unit features two high performance transducers driven by two separate power amplifiers.

One amplifier/driver combination handles midrange and high frequency information, while the other channel reproduces information below the 500 Hz crossover point.

Stereo signals are summed to the midrange/woofer combo for reproduction through the monaural speaker system, while the full dual channel signal is sent to a headphone output for full stereo (left and right channel) monitoring.


The HRS-1S comes equipped with a ganged stereo volume control, power indication LED, stereo/mono toggle switch, 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 HRS-1S features one pair of balanced XLR inputs and one pair of XLR loop-through connectors for connecting to downstream equipment.

Power is provided from an external power supply connected through a jack on the rear panel.
