Wohler AMP2-V2DA 4 Channel AES & Analog Summing Audio Monitor - AMP2-V2DA
AMP2-V2DA
4-channel AES audio summing, metering and monitoring unit that selects between 2 AES input pairs or 4 analog inputs.
The AMP2-V2DA is a complete exceptionally high quality stereo audio monitoring system in a compact two rackspace cabinet, for listening to 2 and monitoring up to 4 channels simultaneously from Analog and AES/EBU Digital sources.
This unit contains three audiophile-quality drivers and three power amplifiers; two 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.
The AMP2-V2DA features four 53 segment high-resolution tri-color LED level meters showing simultaneous VU and PPM for superior level-metering, allowing you to monitor up to 4 channels simultaneously.
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.
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 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, usage automatically mutes the speakers.
The AMP2-V2DA is ideally suited for use in VTR bays, mobile production vehicles, teleconferencing installations, multimedia systems, satellite link and cable TV facilities, and on-air radio studios.
Built and rigorously tested in the USA, the AMP2-V2DA is backed by a strong warranty and a “Satisfaction Guaranteed” return policy.
