Grass Valley Four-Channel Audio A-to-D Converter With Delay (Brand new)
- Brand: Grass Valley
- Model Number: 8921ADT
- Product Code: BS17397
- Availability: In Stock
The 8921ADT provides conversion of four channels of analog audio to two digital audio streams. In addition to conversion, it offers two forms of delay. These delays are summed—a fixed delay of up to 1.5 seconds and a variable delay based on a signal from video decoders fitted with frame synchronizers or directly from a frame sync card, enabling adjustment for large, fixed lip sync errors while continually adjusting audio delay to match video delay created by the frame synchronizer. Operational modes allow modification to the outgoing signal, such as levels, channel swapping, channel summing, and phase inversion plus channel pairing for the digital audio streams. Many adjustments to this card can be performed directly on the module card-edge controls, while a few of the more complex adjustments require the Web-based interface or the Newton control panel.
