IQDAA00
Four-channel Digital to Analog Audio Converter
The IQDAA00 converts two AES/EBU digital audio streams into two analog stereo pairs, or four analog mono channels. The AES streams are converted to analog with 24-bit resolution, and the IQDAA00 also provides proc amp control, channel routing and mixing, up to 0.5s of tracking audio delay and additional fixed delay of up to 3s adjustable in 1 ms steps.
FEATURES
- Converts two AES/EBU digital audio streams into four analog audio channels
- Channel-level (sub-frame) routing
- 4 off 4 channel assignable audio mixers
- Flexible audio delay including per pair fixed delay, common fixed delay and tracking delay
- Variable audio delay of up to 0.5s which seamlessly tracks an external video delay via RollTrack/GPI input
- Audio proc amp (gain, mute, polarity)
- GV Orbit control and monitoring compatible
