monitoring environment. The LED associ-
ated 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 refer-
ence output level. Note that the system’s
default reference level is full mute so “out
of the box” the Model 77B will display four
horizontal lines 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 fl ash. The monitor output level can
reach this exact level through the use of
the rotary level control by itself or through
the setting of the rotary level control in
conjunction with the dialnorm data and dim
function. Whatever path the output level
takes to reach the reference level value, it
will cause the reference level LED to fl ash!
Mute All
Pressing the mute all button causes the
six channels associated with the surround
monitor output 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 ac-
tive. Note that if mute all is enabled via the
remote mute all function, the mute all LED
will fl ash. Also, the mute all function does
not impact the auxiliary monitor output.
Dim
The dim function is provided for user
convenience, allowing the surround moni-
tor output level to be reduced by a fi xed
amount. The Model 77B’s confi guration
mode allows the dim level to be selected
from among four choices: –10.0, –15.0,
–20.0, or –25.0 dB. Pressing the dim but-
ton will enable the function. The dim button
is always set to “latch” the function on and
off. The 4-digit display, when selected for
output level mode, will indicate the re-
vised monitor output level. If the requested
“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
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 fl ash.
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
attempt 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.
