Wohler Technologies – AMP2-VSDA

The AMP2-VSDA is a complete, exceptionally high quality stereo audio monitoring systems in compact, two rackspace cabinets. It contains three audiophile-quality drivers and three power amplifiers; two amplifiers (and two speakers) that reproduce midrange and high frequency information in stereo, and a third amp/driver combination (and speaker) that handles summed Low Frequency (LF) information below the 500 Hz crossover point. The AMP2 series unique audio design has two important advantages. First, it provides optimally focused sound in an Ultra Near Field tm (1 to 3 feet) environment. This allows higher SPL for the operator while reducing overall ambient sound and adjacent bay crosstalk. Second, electronic rather than acoustic cancellation of bass frequencies provides positive audible detection of reversed polarity (“out of phase”) audio feeds. A unique LED display also visually shows “phase” (polarity) relationships of the signals selected for monitoring.

The AMP2-VSDA models are both audio monitors capable of monitoring any of four selected source channels through the stereo speaker system while simultaneously visually monitoring all four channels of the selected source via four high- resolution 53-segment tri-color LED bargraph level meters. A toggle switch on the front panel allows selection between SDI or AES input sources. Pushbutton switches on the front panel are used to independently assign any of the selected four channels to the left and right speakers. AES signal status is indicated by two bi-color (red/green) LEDs while SDI signal status is
indicated by one bi-color (red/green) LED. The rear panel for the AMP2-VSDA feature an SDI input and loop-through on BNC connectors, two AES inputs on unbalanced BNC connectors, two alternate AES inputs on balanced XLR connectors, two AES outputs (converted from the SDI input) on BNC connectors, four analog outputs (of the selected digital source) on balanced Phoenix connectors, and a stereo analog output of the two channels assigned to the left and right speakers on two balanced XLR connectors. The AMP2-VSDA model features an additional four analog inputs on XLR connectors with a switch on the front panel for selecting between the selected digital (AES or SDI) and analog inputs.

Wohler Technologies proprietary three-LED stereo phase indication feature allows visual monitoring of phase relationships of the sources selected for monitoring through the speakers.
