Revision 1 2012-13CDC FOUR

Layers

On an analogue mixer, the necessity for every channel (input or output) to have

its own set of controls and electronic hardware inevitably means that the physical

size of the mixer becomes proportional to the number of channels. An analogue

mixer with many inputs and outputs has a very large “footprint”.

This relationship may be dispensed with in a digital mixer, which allows a small

control surface to control large mixer congurations.

On the CDC FOUR, in 19” of control surface width, sixteen faders can control

up to 48 mic/line and 8 stereo inputs, plus eight Aux sends, eight VCA masters,

two internal FX returns and four output groups. This is achieved by arranging all

these various fader-controlled channels into ve* layers. Only one layer at a time

is active; the faders, with their associated MUTE, SOLO and SEL buttons control

the sixteen channels in that layer.

NOTE: The red MASTER fader always controls the main stereo output – it is not

part of any layer.

The active layer is selected by the ve LAYER SELECT buttons ([7] on “Top view

- control surface” on page 13).

The rst three layers make mic/line inputs 1-16, 17-32 and 33-48 respectively

available to the fader set. The layers corresponding to mic/line inputs 17 and

above will only be operative if the CDC RACK stagebox is connected to the mixer.

The fader assignments for the mic/line input layers are printed on the fader panel

above the faders.

The remaining two layers assign a combination of stereo inputs, VCA masters,

group outputs, Aux sends and FX masters to the fader set. The fader assignments

for these layers are printed on the fader panel below the faders.

* The faders may also be assigned to control the 1/3-octave graphic equaliser available to the main

stereo output; this effectively consitutes two additional layers.
