button. The LED associated with the dim
button will light whenever dim is active. If
dim mode is enabled via the remote dim
function the dim LED will flash.
It’s worth using a few sentences to discuss
the auto dim off function. Whenever dim
is enabled due to the dim button being
pressed, as well as the rotary level control
being active (reference level mode is not
active), changing the setting of the rotary
level control will automatically turn off dim.
The auto dim off function is a unique at-
tempt at protecting the aural health of
users. No longer will there be a heart-
stopping blast of audio when the dim but-
ton is pressed, supposedly to enable dim,
but actually turning dim off because it was
already enabled. It’s hard to explain unless
you’ve experienced this in person—trust
us, this situation can and does happen!
Note that the auto dim off function is not
active whenever dim is enabled due to
the remote dim function being active. This
allows remote control equipment, such
as a talkback system, to reliably dim the
monitor outputs.
Rotary Level Control
The rotary level control is used to manually
adjust the monitor output level. The level
control provides the ability to adjust the
monitor output level over a 70 dB range.
Technically the rotary level control is a
24-step-per-revolution mechanical encod-
er. The amount of level change in dB per
step (“click”) will depend on how quickly
the control is turned. When changed slow-
ly, 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 four full turns. But the Model
77’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 reference level.
Note that the rotary level control is not active
when the reference level function is on and
auto reference level off is off. Whenever the
rotary level control is used to set the output
level for minimum, the monitor output chan-
nels will automatically mute. Technically, this
has the same effect as when the mute all
function is active.
Channel Mute/Solo
The mute/solo mode button and the six
monitor output channel buttons, along with
associated LEDs, work together to provide
excellent operating flexibility. Depending
on the configuration of the mute/solo func-
tion, mute or solo activity will take place pre
(before) or post (after) the downmix func-
tions. When the mute/solo function has been
configured to post downmix the channel pop
solo mode can also be enabled.
The channel mute/solo mode button allows
the operator to select between the mute
and solo functions. It is also used to select
which solo mode, normal or channel pop,
is active. Going from mute mode to solo
mode, or vice-versa, clears all active mutes
or solos. Pressing the mode button twice is
a legitimate means of quickly clearing muted
or soloed channels.
In the mute mode, multiple channels can
be muted simultaneously. A channel that
is muted has its associated LED turned
on. In solo mode multiple channels can
be soloed simultaneously. A channel that
is soloed has its associated LED flash on
