Wohler AMP1A-LP10S 2CH Active Rackmount Ultra-Nearfield Stereo Speaker Monitor with 10 Stereo Inputs and 10-Segment LED Meters, Single

The AMP1A Series monitors provide self-powered, full fidelity stereo audio monitoring of 2 analog channels (1 stereo pair) in the smallest rack space possible. These units contain four high performance transducers driven by three power amplifiers: one amplifier/driver combination handles midrange and high frequency information in stereo, while the second handles summed low frequency information below the 500 Hz crossover point.

The unique design provides optimally focused sound for operators in an ultra near field (1 to 3 ft.) 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 higher 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; usage automatically mutes the speakers.
