B-channel See A-channel above.
Balanced line A balanced line consists of two identical conduc-
tors that carry the same signal but have oppo-
site polarity with respect to ground. Balanced
lines are very useful in reducing or eliminating
unwanted interference. Interference induced in
each conductor signals have the same polarity
in both lines and the noise currents flow in the
same direction. At the load end of the line, noise
currents are found to be opposite in polarity, but
equal in amplitude, so in theory, they cancel
completely. In practice, interference signals do
not cancel completely due to small differences
in the inductance of each conductor.
bargraph meter Meter that indicates the signal level by means of
LEDs.
Boost To increase the level of amplification of a certain
frequency (-range).
boot-up Start-up procedure.
bus cable Cable that inter-connects the frames in a con-
sole system.
BUS CONFIG Option in the CCM menu system. Send busses
1 - 8 can be configured for either mono or
stereo.
bussed together Console frames that are inter-connected by
means of a bus cable are said to be bussed
together.
By-pass By-passing something is the same as skipping
it, for example, stopping the channel VCA from
being controlled by the DC Master fader
requires the DC Master fader to be by-passed.
Call Remote Feature of the Osc&Comms module that acti-
vates a call light at a remote location.
CC Continuous Controller (MIDI-function).
CCM Abbreviation of Central Control Module.
CCM memory Memory space in the Central Control Module (at
present the CCM has 128 memory locations).
CEN Abbreviation of Centre channel
Central Control Module See CCM above
Centre channel The middle channel in a Left - Centre - Right
(LCR) system.
Centre level Located on all Input Channel modules, the Cen-
tre level control is used to set the post-fade sig-
nal level to the centre output of the LCR module
if the Centre-switch is activated. This can be
used to mix or balance signal levels when the
centre output is used as a separate mono bus in
conjunction with the standard L-R bus. If the
LCR switch is activated this control is inactive
Centre switch Switch on all Input channel modules used to
route the output directly to the Centre bus.
