CDC seven
Principles of Operation
Switching the CDC seven on
The PWR button ([1] at page 20) is a “soft” button for starting and powering-
down the surface. When the surface is not operative but connected to its PSU
4800 power supply (supplies) with the PSU(s) powered on, the button illuminates
red. A short press initiates the console boot sequence, the internal computer runs
standard BIOS and diagnostics routines and power is applied to the internal audio
DSP section. The PWR button then illuminates green. At the end of the power-on
sequence, a dialogue box appears on the Main Screen as shown below:
Touching YES in answer to the question will reload the snapshot saved during the
last power-down and reinstate the console to the last-known settings. Touching
CANCEL will result in the console operating in its ‘default’ state, without a scene
loaded – i.e., no channel names, routing or processing will be active.
A ‘long’ press on the CUE LIST button at any point after initial boot-up will
re-invoke the power-on snapshot window: this is useful if the CANCEL button has
been pressed inadvertently.
For safety reasons, the CDC seven boots up with the MUTE ALL function active:
all console outputs from both the stagebox(es) and the local analogue I/O are
‘hard’-muted. Press the MUTE ALL button ([5] at “Master Section and Master
Fader Bay:” on page 19) to cancel this mode and activate the outputs.
Switching the CDC seven off
To shut the surface down, ‘short-press’ the PWR button again, and a dialogue
box will be displayed asking if the console should be powered down (Shut
Down), or restarted (Restart) while continuing to process audio. Selecting Shut
Down initiates a power-down sequence, ensuring that the computer is shut
down correctly. When the surface shuts down, a snapshot is taken of the current
console status: this includes all input and output channel settings.
Alternatively, the surface can be powered down via the Control Screen using the
Shutdown button in the Settings menu, which opens the same dialogue box.
The internal computer may be ‘forced’ to reboot by pressing the PWR button for
approx. 1 – 3 secs. This function may be useful in the unlikely event of a major
computer crash; audio continues during the reboot.
If the PWR button is held pressed for at least 5 secs., a complete shutdown of all
console functions is forced.
