GLOSSARY-III
Revision R2005-2 R-Type
channel Input or output signal that forms a part of the
final mix.
CHANNEL PRIORITY Mode in which an input PFL overrides an output
Listen.
channel VCA Voltage controlled amplifier for controlling the
input channel or output group signal. The
degree of amplification is determined by the
VCA drive voltage, derived from a fader or
potentiometer.
CHECK Feature that allows the operator to use an input
channel MUTE button as a ‘solo-in-place’ but-
ton.
CLEAR CLEAR buttons are used to cancel a selection
or to clear the CCM of one or more memories.
CMRR Common mode rejection ratio is the ratio of
response for a normal mode signal to the
response for a common mode signal of the
same amplitude. CMMR is usually specified in
decibels.
cold Refers to pin 3 on an XLR-connector. The signal
on pin 3 is opposite in polarity to pin 2 and
hence is referred to as cold.
Common mode Where all currents (signal and interference) flow
in the same direction in each conductor. Nor-
mally, interference currents are an unintended
by-product of the cable connection and the main
cause of cable interference problems.
comms functions Functions that allow an operator to communi-
cate with remote locations.
Comms MIC Microphone used for communicating with
remote locations.
Comms MIC input Microphone input located on the Osc & Comms
module used for various talkback and communi-
cations functions.
communication functions Refers to the Osc & Comms module, which in
addition to its oscillator functions also has com-
munication functions as described under
Comms MIC and Comms MIC input above.
configuration The arrangement of features to produce a cer-
tain outcome.
Configuring See configuration above.
console mapping Information stored in the CCM as to how the
console is configured.
console modularity Frame design concept allowing any module to
be put in any position in the frame.
console snapshot Scene memory with no dynamic contents.
COPY MEM Message displayed on the CCM when CPY is
pressed. The message prompts an input from
the user as to which memory number to copy.
Current Scene Point of reference when using the functions Pre-
vious and Next on the Central Control Module.
