The AMP1-S8MDA 8 Channel HD-SDI, SD-SDI,AES/EBU and Analog Audio Monitor from Wohler is an audio monitoring system that offers (8) channel analog, AES/EBU, SD/HD-SDI digital multi-channel audio monitoring and conversion, as well as professional level metering. This unit is ideally suited for work in TV facilities, studios, VTR bays, mobile production vehicles, satellite links, or any rackmount environment, among many other possible applications and settings.
It contains (3) audiophile-quality drivers and (3) power amplifiers. The unit also has (2) speakers and amplifiers that reproduce midrange and high-frequency information in stereo. A third amplifier-driver combination manages summed LF information below the 500Hz crossover point. Level metering is enhanced by the monitor's (8) 26-segment high-resolution tri-color LED level meters, which display simultaneous VU and PPM. The front panel also features an LCD display with phase-polarity relationships. Output-limit circuits protect the speakers and magnetic shielding allows placement adjacent to video monitors.
These design elements provide ideal sound output for operators in an ultra near field working environment of 1 to 3'. Moreover, the setup rivals the performance of separate monitor pairs without the problems associated with a separate add-on installation. The monitor's design also provides the operator with a higher SPL while reducing overall ambient sound and adjacent bay crosstalk.
The monitor's extended high-frequency response can reveal potential problems with audio whine and hiss. Electronic cancellation of bass frequencies provides positive audible detection of out-of-phase reversed-polarity audio feeds. A headphone jack is included on the front panel and using it automatically mutes the speakers.
