Sonifex S2-ODPF - S2 Digital PGM Output Channel with Master Fader

This channel is common to every mixer and provides a digital and analogue output from the PGM 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 PGM output and mono output is on a 15 way D-type connector. This also carries the two sets of latching relay contacts for the control room mutes.


The main power input from the S2-PSU is on this channel. Button switches at the top of the channel select the mono output source from either PGM or AUD. The Mono compatible output could be used to feed a mono transmitter or any station output monitoring system that requires a mono signal, such as a background music system.

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 sync signal. The channel automatically locks to a valid sync clock, flashing if sync is lost. Synchronisation can be jumper disabled.
