The VMMDA-1 audio monitor permits stereo monitoring with excellent fidelity exceeding that of ordinary monitors in a 1U rack-size.
The unit can monitor analog, AES, standard SDI, or HD-SDI audio sources.
A 3-position toggle switch on the front panel selects between the three input sources (analog, AES, or SDI).
When SDI is selected as the source, an 8-position rotary SDI Group Select switch selects which of the eight SDI channel pairs will be monitored.
An LED above the SDI Group Select switch indicates the "lock" status of the SDI source.
Both models feature dual 10-segment LED bargraph meters that provide visual indication of input levels.
Other front panel features include volume and balance controls, power indication LED, headphone output, and phase indicationLEDs.
Wohler Technologies proprietary three-LED stereo phase indication feature allows monitoring of phase relationships of the selected stereo inputs.
Volume and balance controls are standard, but can be reconfigured as A volume/B volume via an internal jumper.
Two front-firing midrange tweeter speakers and a compact high-performance woofer are arranged in Wohler Technologies' popular bi-amp design.
The summed bass feature is important for audible detection of out-of-phase conditions.
Speaker amp limiters prevent accidental damage to speakers from high input levels.
The rear panel features an SDI input and output on BNC connectors, an AES input on a BNC and Phoenix connector, two analog inputs on Phoenix connectors, and an analog stereo output of the selected source on Phoenix connectors.
The VM Series, from our line of "confidence plus" audio monitors are very compact and light, digital and analog audio monitors at very cost effective prices. The single-rack space monitors offer excellent full-range fidelity far exceeding that of competitive units. Two front-firing midrange tweeter speakers and a compact high-performance woofer are arranged in Wohler Technologies' popular bi-amp design. All Wohler speaker systems are protected against blowout by limiters.The summed bass feature is important for audible detection of "out of phase" conditions.
Electronic rather than acoustic cancellation of bass frequencies provides positive audible detection of out-of-phase (reversed polarity) audio feeds. The units feature 2 ten-segment VU LED bar graph level meters. Fast and averaging "phase" LEDs give visual alert of "out of phase" conditions. A three-way toggle switch selects between the analog or digital inputs. Muting may also be activated from a switch remote from the rear panel (optional extra). An auxiliary analog output of the selected analog or digital source is provided on the rear panel.
The VM Series monitors are completely magnetically shielded to allow interference-free operation immediately adjacent to all CRT video monitors.The light weight and shallow depth chassis compared to similar type units, make them ideal for use in portable and mobile vehicle applications.
