Input Mute/Solo
The input mute/solo function allows chan-
nels associated with the surround input
channels to be muted, or be selected for
individual “solo” monitoring. It’s very impor-
tant to understand that the input mute/solo
function directly impacts the input channels,
but not necessarily only the directly associ-
ated output channels. The reason is bass
management. The bass management func-
tion will redirect low-frequency energy to
the monitor output’s subwoofer channel. So
for example, a full-range signal coming into
the system on the left channel of surround
A will have content coming out of both the
left and subwoofer monitor output channels.
Using the input mute/solo function to mute
the left channel will cause the content in
both the left and subwoofer monitor output
channels to mute.
Associated with the input mute/solo function
are nine buttons and ten LED indicators.
They work together to provide excellent op-
erating flexibility. The mute/solo mode but-
ton allows the operator to select between
the mute and solo modes. Going from mute
mode to solo mode, or vice-versa, clears all
active mutes or solos. Pressing the mode
switch twice is a legitimate means of quickly
clearing all muted or soloed channels.
In the mute mode, multiple input channels
can be muted simultaneously. A channel
that is muted has its associated LED lit.
The solo mode can operate in one of two
ways: additive or exclusive. How solo oper-
ates depends on the configuration as set in
the Model 79 Control Console. In additive
solo mode, multiple input channels can be
soloed simultaneously. A channel that is
soloed has its associated LED indicator
flash on and off, while the LEDs on the
non-soloed channels are not lit.
As expected, in the exclusive solo mode
pressing a channel button will cause that
channel to be soloed. But, in addition, any
other channel or channels being soloed
will go back to their normal, non-solo con-
dition. Thus the exclusive solo mode al-
lows rapid “soloing” of individual channels.
Should more than one channel need to be
simultaneously soloed, simply push and
hold a channel button, then add the extra
channels by momentarily pressing their
buttons.
Output Mute
The two buttons associated with the output
mute function provide a means of directly
muting the monitor output channels. These
serve as an aid in observing the perfor-
mance of the loudspeaker system. The
output mute function organizes the moni-
tor output channels into two groups: mains
and sub. The mains group consists of the
seven main output channels, L, R, C, SL,
SR, BL, and BR. The sub group consists
of only the subwoofer output channel. Two
buttons and associated LED indicators are
used to control the output mute function.
Both buttons function in a push on/push
off manner.
It may be confusing at first to imagine why
the output mute buttons are important. The
reason, like the input mute/solo function,
is bass management. The input mute/solo
function allows observation of the chan-
nels associated with the surround inputs.
But soloing a single channel, such as the
left input of surround A, may result in audio
content coming out of the system and be-
ing reproduced by the left and subwoofer
loudspeakers. By maintaining the left chan-
nel in the input solo mode, an operator can
use the output mute function to indepen-
dently mute the left and subwoofer output
channels as desired.
