Wohler VAMP AC-3 Video & Audio Monitor with Internal Dolby Digital AC-3 Decoder
The VAMP AC3 is a color video and stereo audio monitor designed specifically for simultaneous monitoring of composite analog video and the six digital audio channels associated with ATSC/DVB (AC-3/Dolby Digital) programming in a 2U rack-size.
The unit features a built-in color 4" LCD screen with front panel controls for brightness, chroma, tint (NTSC only), and contrast.
NTSC or PAL signals are automatically detected, displayed, and indicated.
The VAMP-AC3 accepts AC-3 (Dolby Digitalr) and/or AES/EBU (PCM) audio input signals.
Indicator LEDs are provided on the front panel to identify the selected source as being AC-3 or AES.
A toggle switch and LED are also provided to indicate and allow selection between two AC-3 Pro-16 signals, if they are present.
High-resolution, wide-range LED bargraph level meters are provided for all six channels.
The 53 bi-color segments, spanning a range of 65 or 90 dB, simultaneously display signal levels according to both the PPM and VU standards.
Bargraph brightness is adjustable via a trim pot.
Both Left/Right and Front/Surround "Phase"/Polarity LED indicators are provided to alert of possible phase cancellation from mix-down in any likely playback situation.
To isolate possible faults, rotary switches let the operator route any one or pair of inputs to left and right speaker channels for acoustic monitoring.
A toggle switch is provided, which mixes all six channels down to two for listening to all channels at once and LEDs are provided to indicate this selection.
The rear panel features an analog video input and loop-through output on BNC connectors.
The first audio input section features an input and loop-through output on balanced XLR connectors or unbalanced BNC connectors.
The second audio input features an input either on a BNC or an XLR connector.
Two XLR connectors output the selected audio source as analog audio. Power is indicated by a front panel LED.
