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.
