Wohler AMP2-VSDA 4 Channel SDI Summing Audio Monitor - AMP2-VSDA
AMP2-VSDA
4-channel SDI audio summing, metering and monitoring unit that selects between 1 SDI audio group, 2 AES input pairs or 4 analog inputs.
The AMP2-VSDA audio monitor provides self-powered, full-fidelity stereo monitoring in a compact, two rack space (2U) cabinet.
The unit features an SDI input and reclocked output on BNC connectors, two AES inputs on BNC connectors, four analog inputs on XLR connectors, two AES outputs (de-embedded from the SDI source) on BNC connectors, four analog outputs (deembedded from the selected digital source) on four Phoenix connectors, AES/SDI source select switch, A/D select switch, and four high-resolution 53-segment tri-color LED bargraph level meters.
Two banks of four buttons on the front panel are used to independently assign from one to four (summed) channels to each of the two (left and right) speaker channels.
A pair of balanced XLR connectors output the selected audio source for connection to downstream equipment.
The level meters may be adjusted for a number of parameters, including Display Mode, Peak Hold, PPM Ballistics, Alternate Scales, and Phase Correlation via rear panel and internal DIP switches. An Auto Line Level Calibrate feature is also available.
The audio amplifier section features five high performance transducers driven by three power amplifiers: two 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).
Output limiter circuits are incorporated to protect the speakers, and extensive magnetic shielding allows placement immediately adjacent to magnetically sensitive equipment, such as video monitors.
The unit front panel also features two AES status LEDs, an SDI status LED, Wohler's' proprietary three-LED stereo phase indication feature, volume control, balance pot, power indication LED, and stereo headphone output.
