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 encoder.
The amount of level change in dB per step
(“click”) will depend on how quickly the
control is turned. When changed 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 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 fl ash 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 func-
tion 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 channels 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 fl exibility. The channel
mute/solo mode button allows the operator
to select between the mute and solo func-
tions. 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 legiti-
mate 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 fl ash on
and off, while the LEDs on the non-soloed
channels are not lit.
If the system has been selected for the
normal solo mode the solo LED associ-
ated with the mute/solo mode button will
light steadily. If the system has been se-
lected for the channel pop solo mode the
LED will fl ash. At any time the system can
be changed between normal solo mode
and channel pop solo mode. Simply press
