change will be indicated by the LED, which
will now light steadily whenever the stereo
to mono downmix function is enabled.
Monitor Output General
Functions
Four buttons and one rotary control are
associated with the monitor output func-
tions. The buttons control operation of the
surround and stereo outputs, reference
level, mute all, and dim functions. The
rotary level control is used to manually
set the monitor output level.
Surround and Stereo Outputs
The surround/stereo function allows selec-
tion between two different loudspeaker sys-
tems. When the surround output is selected
the six surround (5.1) output channels are
active. The two channels associated with the
stereo output are muted. When the stereo
output is selected the left and right channels
associated with the stereo output become
active; the six channels of the surround
output mute.
Remember that the Model 77 Control Con-
sole can be configured to disable the sur-
round/stereo button. If the button is pressed
and nothing happens, this must be the case!
Reference Level
The reference level button sets the monitor
output level to a preset value. Technical per-
sonnel, using a sound pressure level (SPL)
meter and precision signal source, should
have set this level to meet the requirements
of the specific monitoring environment. The
LED associated with the reference level
button will light whenever the function is
active. Whenever the reference level mode
is active the rotary level control is disabled.
The 4-digit display will indicate the reference
output level. Note that the system’s default
reference level is –60.0 dB so “out of the
box” the Model 77 will display
–60.0 when
reference level mode is enabled.
The reference level LED also serves as a
calibration aid. If the reference level mode is
not active, whenever the monitor output level
is precisely the same as that stored for the
reference value the reference LED will flash.
Mute All
The mute all function is highly complicated
to operate—not! Pressing the mute all but-
ton causes all monitor output channels to
mute. The 4-digit display indicates the mute
condition by showing four horizontal dashes.
The mute all button is always set to “latch”
the function on and off. The LED associated
with the mute all button will light whenever
mute all is active. Note that if mute all is
enabled via the remote mute all function,
the mute all LED will flash.
Dim
The dim function is provided for user conve-
nience, allowing the monitor output level to
be reduced by a fixed amount. The Model
77’s configuration mode allows the dim level
to be selected from among four choices:
–10.0, –15.0, –20.0, or –25.0 dB. Press-
ing the dim button will enable the function.
The dim button is always set to “latch” the
function on and off. The 4-digit display will
indicate the revised monitor output level.
If the “dimmed” output level is equal to or
less than the minimum attenuated level, the
monitor output will go into full mute and the
display will show four horizontal dashes.
When dim is active the monitor output level
reduction will apply no matter whether the
monitor output level is being set by the
rotary level control or by the reference level
