A-channel The odd numbered mix group on a group mod-
ule. When working in stereo, the left channel is
reproduced by channel A and the right channel
by channel B.
ADDITIVE function An additive function is provided in that every
new PFL or Listen signal is mixed with the previ-
ous one.
assign The process of, for example, allocating a Master
fader to control a number of input channels. The
input channels can then be said to be assigned
to that specific Master fader.
assignable LED meter LED-meter that measure the signal level of more
than one source.
assigned See assign above.
assignment See assign above.
Assignment buttons Buttons that need to be pressed to assign input
channel faders to a DC Master fader or a Mute
group. The assignments buttons include the
numerical buttons (1 - 8), located on the channel
modules.
aux group A mixing group for signals that are not part of
the main audio outputs on a console.
aux output Level controlled output of the resulting mixed
signals of the auxiliary mixing group.
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 cer-
tain frequency (-range).
boot-up Start-up procedure.
bus cable Cable that inter-connects the frames in a con-
sole system.
