13 Output Channels
There are six dierent output channels, available for installation in the mixer as well as a
blank channel and script space. The channels are each covered in the following chapters,
but a summary follows:
S2-ODP Digital PGM Output Channel &
S2-ODPF Digital PGM Output Channel With Master Fader
This channel is common to every mixer and provides a digital and analogue stereo output
from the PGM mix bus and a mono analogue output. The digital output is available as a
balanced AES/EBU signal via standard XLRs or as S/PDIF on phono sockets. The sample rate
can be set automatically or by internal jumpers from 32 kHz to 96 kHz . The output sample
size can be set to 16, 18 or 24 bits on Version 1 modules, but is always 24 bits on Version 2
modules.The balanced analogue PGM output and mono output is available on a 15 way
D type connector.
Button switches at the top of the channel select the mono output source. The S2-ODPF
version has output faders for production use.
S2-ODA Digital AUD Output Channel &
S2-ODAF Digital AUD Output Channel With Master Fader
This channel is 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 standard
XLRs or as S/PDIF on phono sockets. The sample rate can be set automatically or by internal
jumpers from 32 kHz to 96 kHz. The output sample size can be set to 16, 18 or 24 bits on
Version 1 modules, but is always 24 bits on Version 2 modules. The balanced analogue AUD
outputs are available on a 15 way D type connector.
Button switches at the top of the channel select the monitoring source to the meterbridge.
The S2-ODAF version has output faders for production use.
S2-OMC Control Room Monitor Channel
The Control Room Monitor channel is used for the monitoring of various sources on the
control room loudspeakers and (presenters) headphones. A suitable power amplier
connected to the channel monitor output must be used to drive the loudspeakers. A front
panel control is used to vary the monitor level. Headphones can be driven directly from the
channel headphone connector on the front or rear panel via the level control.
A 4 way electronically interlocking switch bank selects the source routed to the speakers
and headphones from either of two external inputs, the PGM, or AUD output. “Auto PFL”
buttons adjacent to each level control allow the monitoring of PFL when an input channel
has been selected to CUE/PFL. In addition, Split PFL can be selected to the headphones,
which will place the selected source in mono in one ear and PFL in mono in the other.
This channel controls the signal conditioning for the talkback input and output and routes
these signals to and from the talkback bus. Internal jumpers can be congured to allow
talkback to replace or dim the selected source. A Global Talkback system can be congured
