for Surround
The amount of level change in dB per
step (“click”) will depend on how quickly
the control is turned. When rotated slowly,
each step represents a 0.5-dB change in
level. In this case, to traverse the entire
level range would require rotating the con-
trol more than five full turns. But the Model
77B’s software detects when the control
is rotated more quickly and increases the
amount of level change in dB per step. A
little experimentation will allow the user to
acquire a good “feel” for how best to use
the control.
The reference level LED will flash when
the rotary level control sets the output
level to be the same as the stored refer-
ence level. Whenever the rotary level con-
trol attempts to set the output level for less
than –70.0 dB, the post-fader surround
digital and analog monitor output chan-
nels will automatically mute. As previously
discussed, the 4-digit display indicates the
mute condition by showing four dashes
(– – – –).
If the mute all function is active the rotary
level control won’t have an impact on the
post-fader surround digital and analog
monitor output levels. It’s also not active
whenever the reference level function is
active, except if the auto reference level
off function has been enabled.
Channel Solo
The channel solo function allows specific
channels to be selected for individual or
group “solo” monitoring. The function im-
pacts the post-fader surround digital and
analog monitor outputs, taking place elec-
trically “after” the source selection, input
delay, downmix, and level control functions.
Two solo modes are available, normal and
channel pop. In the normal solo mode
the level of a channel selected for soloing
actually doesn’t change; the solo function
causes the non-soloed post-fader surround
monitor output channels to mute. In the
channel pop solo mode the level of the
soloed channel will increase, while the level
of the non-soloed channels will decrease.
In this way the soloed channel will “pop
out” from an audio mix so as to be more
easily observed. The actual level changes
that occur in pop solo are dependent on
how the system has been configured.
Six buttons and associated LEDs, along
with the auxiliary stereo monitor output
enable button, are associated with the
channel solo function. To solo a channel
simply requires pressing one of the solo
buttons. The buttons function in a press-
to-enable/press-to-disable “latching” mode.
The LED associated with a soloed channel
is used to indicate that solo is active.
The auxiliary stereo digital and analog
monitor output enable button is used to
select the solo mode. Using this button
the solo mode can be changed any time
between normal and channel pop. Simply
press and hold the auxiliary stereo digital
and analog monitor output enable button
for a few seconds until the channel solo
LEDs light in the desired manner; steady
to indicate normal solo mode and flashing
for channel pop solo mode. Once the state
of the LEDs change (steady-to-flashing or
vice-versa) the desired solo mode becomes
active and the button can be released. The
selected solo mode will be maintained even
after the system is powered down and sub-
sequently powered up. In the normal solo
mode a soloed channel will have its associ-
ated LED light steadily. In the channel pop
solo mode a soloed channel will have its
associated LED flash.
