Revision 1 2012-13 CDC FOUR
Compressor:
THR - adjusts the threshold of the channel’s compressor in the range -48 dB to 0
dB. Default setting is -12 dB.
RAT - adjusts the compression ratio between 1:1 to 20:1. Default setting is 1:1
(i.e., no compression).
LVL – adds gain to compensate for compressor action. Range is -12 dB to +12
dB. Default setting is 0 dB.
IN – switches the compressor into the signal chain. Default is Out.
AUT – in Auto mode, the compressor’s Attack and Release time constants are
not fixed, but programme-dependent, and set by an algorithm which makes the
compressor’s action unobtrusive. In Manual mode, the time constants may be
adjusted from the Dynamics Detail page (see NOTE below).
VIN – enables an alternative compressor algorithm which makes the compressor
act like a leveller, modelling the sound of certain vintage compressors.
NOTE: Additional Compressor parameters are available from the Dynamics
Details screen page – see page 54.
Limiter:
THR - adjusts the threshold of the master output’s separate limiter section in the
range -40 dB to 0 dB. Default setting is 0 dB.
IN - switches the limiter into the signal chain. Default is Out.
Dynamics Global:
BYP - switches the complete dynamics section (compressor and limiter) in and
out of the signal chain. Default is Out.
PST – the dynamics section can be pre- or post-EQ. Pressing PST inserts it after
the equaliser. Default is Off (i.e., dynamics are pre-EQ).
EQ Section:
The CDC FOUR’s stereo master channel is equipped with a 4-band parametric
equaliser, with bell-shelf switching on the highest and lowest bands. The channel’s
frequency response (EQ curve) can be seen on the EQ detail page (see page
54).
IN – switches the HF section of the equaliser into circuit. Default is Out.
FREQ – adjusts the frequency of the HF section of the equaliser. This will be the
centre frequency of a bell filter if the Shelf switch is set to Bell, and the turnover
frequency if it is set to Shelf. Range is 1.5 kHz to 15 kHz. Default setting is 1.5
kHz.
GAIN – allows 18 dB of cut or boost in the selected frequency band. Default
setting is 0 dB (flat response).
Q – adjusts the bandwidth of a bell filter; Q range is 1.0 (wide) to 3.0 (narrow).
Default setting is 1.0. If the Shelf switch is On, the control is inoperative and is
removed from the screen display.
