9. SOLO buttons – perform either a PFL (pre-fade listen), AFL (after-fade
listen) or SIP (solo-in-place) function, depending on settings made through
the Solo Control page on the Control screen. The default modes for input
channels are: mono channels are PFL, stereo channels are AFL; output
channels are AFL only. AFL is post the channel panpot (if in circuit), so
correctly reflects the stereo imaging of the channel being solo’d; if the
panpot is not in circuit, AFL is mono. SIP mode is also available, selected
from the Solo Control page. As well as the master modes, the CDC seven
also features ‘momentary’ and ‘latching’ solo operation:
‘Momentary’ solo – press and hold the SOLO button; solo is active
while the button is pressed and cancels when the button is released.
‘Latching’ solo – a short press on a SOLO button activates solo
mode and the button may be released. Press again to cancel.
‘Block latching’ – press and hold one SOLO button and press
another SOLO button while still pressing the first. This will solo the
block of channels between the two buttons. Note that this mode is
not available if “Auto Cancel” is selected on the Solo Control page.
In use, the SOLO button illuminates in a colour that is mode-dependent.
See the Software Manual for more details of the Solo system.
10. Metering – a 20-segment LED dual bargraph meter is fitted adjacent to
each of the 16 faders in the fader bay. The meters are single when the
selected channel (input or output) is mono, and dual if stereo. The lowest
segment acts as a ‘signal present’ LED, and illuminates at -70 dBFS.
The LEDs are colour coded: the signal present segment is green, the
five highest segments are red, with the top one corresponding to 0 dBFS.
The remaining segments are yellow. A Meter Options page on the
Control screen allows the user to select various meter source options,
including fixed metering of selected layers or “follow” modes, switchable
pre or post-fader. Full details are provided in the Software Manual. There
is additionally an green OPEN LED at the bottom of the meter which
illuminates as soon as the fader is moved from its “closed” position.
11. OLED alphanumeric displays – one per fader. These display the name of
the channel (input or output); this will either be the user-assigned name,
or if the channel has not been renamed, the default name – e.g., Ch. 23.
They are also colour-coded, to match the channel type – stereo or mono,
output buss assignment, etc. The colours are consistent with the usage
elsewhere in the software.
12. INPUT LAYERS and OUTPUT LAYERS buttons – a set of ten buttons
controlling which channels are displayed on-screen. The faders, OLED
displays and the ON, SOLO and SEL buttons below always follow the
on-screen channel strips above. The VCA button displays the VCA
assignment page, and the faders become VCA masters.
13. GEQ button – press this when an output bus is selected (with the SEL
button illuminated) to allow the CDC seven’s graphic equaliser function
for that bus. A 32-band graphic equaliser may be inserted in any or all
output channels, in addition to the channel’s standard parametric EQ.
When GEQ is in use, the OLEDs [11] display the centre frequencies of
each band.
