CALREC Putting Sound in the Picture 73
DYNAMICS 1
Every channel / group / main
path has two dedicated dynamics
processing units that are always
available to them. Dynamics 1 shown
right provides a Compressor / Limiter
and Expander or Gate.
Dynamics 1 controls
The Dynamics 1 controls and
related displays are all located in the
PROCESSING-DYNAMICS 1 panel
mode, as shown in Fig 1.
Dynamics controls and displays
are all colour-coded purple. The
controls are arranged in 3 blocks:-
Compressor /Limiter controls for ON,
Threshold, Ratio, Attack, Recovery and
Gain Make-up. Expander or Gate controls
for ON, Threshold, Ratio, Attack, Recovery
and Depth and 2 bands of Dynamics
sidechain EQ controls for Gain, Frequency
and Q / Response types.
The TFT screen displays a graph of
input level versus output level along with
switchable gain reduction meters, the
position of the Dynamics 1 processing in
the signal path and switches for control
and gain reduction independence of legs
for stereo and 5.1 path legs.
With SCEQ selected on the TFT screen,
it also displays the EQ curve for the
dynamics 1 side-chain. Also shown are
the 8 Dyn Links selector which this path
can be linked to or can be left as No Link
for independent operation .
Both dynamics 1 & 2 can be used
as limiters simply by switching the
compressor in and setting the ratio to
the maximum of 50:1. At this setting, the
input has to increase by a massive 50dB
above the threshold in order for the output
to increase by a negligible 1dB - the signal
is effectively being limited.
