8-channel (2 groups) 3G/HD/SD-SDI audio processor with alternate AES and analog inputs. Mix, monitor, meter and convert to AES and analog.

The AMP1-S8-MDA monitor is an exceptionally high-qualityaudio monitor system offering premium quality 8-channel analog, AES/EBU, 3G/HD/SD-SDI multi-channel audio monitoring and conversion as well as professional level metering. These units contain 3 audiophile-quality drivers and three power amplifiers; 3 speakers and amplifiers reproduce midrange and high frequency information in stereo, while the third amp/driver combination handles summed LF information below the 500 Hz crossover point.

These units feature eight 26-segment highresolution, tri-color LED level meters showing simultaneous VU and PPM for superior levelmetering. The front panel features an innovative LCD 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.

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, 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 and 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.

These units are ideally suited for use in space-critical environments such as TV facilities, studios, VTR bays, mobile production vehicles, satellite links and indeed, any rack mount environment where multi-channel audio monitoring is required.
