The AMP1A-SUM6/RD 6-Channel Analog Audio Mixing Monitor from Wohler Technologies provides self-powered, full-fidelity stereo monitoring of analog audio in a small rack space (1U) with a mounted depth of just 6.5" (16.5cm), 6 audio input channels on a DB25 connector, and 6 individual volume controls. Channels 1, 2, and 3 are summed to the left speaker and channels 4, 5, and 6 are summed to the right speaker.

Each of the 6 channels may be individually adjusted for volume to allow mixing of the overall output. The audio amplifier section features 5 high-performance transducers driven by 3 power amplifiers: 2 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). This design provides optimally focused sound for operators in an ultra near field of 1 to 3' (0.3 to 0.9m) working environment and offers performance comparable to that of many separate monitor pairs, yet does so without the installation hassles, awkward speaker placements, and added-on look. This provides for a high SPL for the operator while reducing overall ambient sound and adjacent bay crosstalk.

Extended HF response reveals potential problems with audio whine or hiss. Electronic rather than acoustic cancellation of bass frequencies provides positive audible detection of out-of-phase (reversed polarity) audio feeds. A headphone jack is provided on the front panel that automatically mutes the speakers. Output limiter circuits are incorporated to protect the speakers, and extensive magnetic shielding allows placement immediately adjacent to magnetically sensitive equipment with no color impurities, such as video monitors. The unit features 6 input channel volume controls, a power indication LED, and a headphone output.
