1. Cadac MegaCOMMS data – 4 x BNC connectors carrying all audio and
control data between the control surface and the stage rack(s). See
“Connecting the hardware” on page 28 for full details.
2. WORD CLOCK OUT – a 96 kHz clock signal is always available at this
connector, at TTL level (0 to +5 V).
3. INPUTS 1 to 8 – eight balanced “local” analogue audio inputs to the CDC
seven, on XLR sockets. These may be the sources for any input channel
in the same way as the remote stagebox inputs They may be used for
connection of FOH sound sources, FX processing, talkback mic, etc.
Characteristics are identical to the inputs on the stageboxes.
4. 48V – eight red LEDs; illuminate when 48 V phantom power is enabled at
the associated input connector.
5. OUTPUTS 1 to 8 – eight balanced “local” analogue audio outputs from the
CDC seven, on XLR male connectors. Any output channel may be routed
to these, to enable the connection of FX processors, recorders, etc. The
talkback/comms output from the CDC seven may also be available here;
this is configured in software via the Control Screen. Characteristics are
identical to the outputs on the stageboxes.
6. MUTE - each analogue output connector has an adjacent red LED. This
illuminates when the physical output is ‘hard’ muted by the internal relay,
either during power-up, when the MUTE ALL button is pressed, or if a
‘hard’ mute is applied to an output from a channel ON button. See [8]
at “

buttons” on page 16 and [5] at “
MUTE ALL
” on page 20 for
more details.
