S2-ODAF : Digital AUD Output Channel
This channel is also common to every mixer and provides a digital and analogue output from the AUD mix bus. The digital output is available as a balanced AES/EBU signal via a standard XLR or as S/PDIF on phono sockets. The balanced analogue AUD outputs are available on a 15 way D type connector which also carries the two sets of latching relay contacts for the studio mutes.
Button switches at the top of the channel select the monitoring source to the meterbridge. Meters in the meterbridge which are connected to the "Monitor Meter" position will display the selected signal from the electronically interlocking PGM, AUD, or CR MON buttons. The CR MON signal source is whatever is being monitored on the presenter's headphone on the control room monitor channel, pre talkback and level control. This signal could be PGM, AUD, EXT 1, EXT 2, or PFL, as selected by the presenter.
The digital output status bits (consumer or professional), output sample size (16, 20 or 24 bits) and sample rate (automatically or by internal jumpers from 32 kHz to 96 kHz) can be set. The digital output can be synchronised from an external input, or from an on-board master clock. There are 4 different sync modes : Master, Auto, Auto Lock and Slave.
The illuminated LOCK LED shows that the digital output is locked to the onboard master clock, incoming Word clock or AES/EBU or S/PDIF compatible sync signal. The channel automatically searches for a sync signal on the Word Clock, or the selected digital input, and automatically locks to a valid sync clock.
If sync is lost then the indicator will flash. Synchronisation can be jumper disabled.
