 In video applications, digital audio sample clocks must be locked
to a video reference. The VRG-1 provides a means to do so, easily
and cost effectively. This module produces word clock and silent
AES outputs that are locked to an NTSC or PAL reference input.
Use the VRG-1 in conjunction with the SoundPals ADC-24, DMIC-
24, DTG-1 or ADAT-3 modules, or with any other digital audio
equipment that requires an AES or word clock reference signal that
is locked to video.
Like all of the SoundPals line, the VRG-1 is housed in a compact,
rugged aluminum enclosure.
Features include:
- Looping video input accepts NTSC or PAL video, color black, or sync
- Outputs for word clock, silent AES, and silent AES3id
- Internal crystal oscillator provides stable 48kHz reference in the absence of an input signal
- Dipswitch selection of mute outputs or revert to internal reference upon loss of input signal
- Alarm output to warn of loss of input signal
