Wohler AMP2-16V 4-Channel Audio Monitor- USED

The AMP2 4-Channel Audio Monitor from Wohler Technologies provides self-powered, full fidelity stereo audio monitoring. This unit features 4 LED level meters showing simultaneous VU and PPM for accurate level-metering of all 4 input sources from the selected input group. The audio monitor contains high performance transducers driven by 3 power amplifiers: 1 amplifier/driver combination handles midrange and high frequency information, 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 of 1 to 3′ (0.6 to 0.9m) working environment and offers performance comparable to that of many separate monitor pairs. 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, and its usage automatically mutes the speakers. The front panel features an innovative LED display of phase/polarity relationships. Output limiter circuits are incorporated to protect the speakers, and extensive magnetic shielding allows placement immediately adjacent to video monitors with no color impurities. This monitor is suitable for VTR bays, mobile production vehicles, teleconferencing installations, multimedia systems, satellite link and cable TV facilities, and on-air radio studios.
