as a talkback system, to reliably dim the
monitor outputs.
Rotary Level Control
The rotary level control is used to manu-
ally adjust the monitor output level. It is
active any time the reference level function
is not active. When the rotary level control
is set to give the same output level as the
preset reference level, the reference LED
will flash. Note that when the level control
is set to its fully counterclockwise position,
maximum attenuation is achieved, but not
a full mute. The mute all function should
be used to fully mute the monitor outputs.
The rotary level control and, if configured,
the remote level control work together in
an interesting fashion. The control which
was turned last sets the monitor output
level. This makes it very simple to move
from using one control to the other, with no
remote enable/disable buttons or switches
to activate.
As a visual aid, if the monitor output level
is changed using the remote level control,
the remote activity LED on the Model 591
will flash. This LED will continue to flash
until a monitor-output-level-related param-
eter on the Model 591 changes. Level-
related parameters include turning the
rotary level control, or enabling the refer-
ence level, mute all, or dim functions. The
remote activity LED flashes in this manner
as a warning, preventing an operator from
wondering why the level has “mysteri-
ously” changed. A change in monitor level
can have serious consequences to an
audio mix, so this LED serves as an alert
that a change has occurred. Remember,
if you are worried about the monitor level
being changed remotely during an impor-
tant mix, use the reference level function
to “lock out” the local and remote level
controls.
Mute/Solo
The mute/solo mode button and the two
monitor output channel buttons, along with
associated LEDs, work together to provide
excellent flexibility. The mute/solo mode
button allows the operator to select be-
tween industry-standard mute and solo
functions. The mute and solo functions
use the mute relays in the Model 58 to
enable or disable output channels. 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 a muted
or soloed channel.
In the mute mode, a channel that is muted
has its associated LED turned on. In the
solo mode a channel that is soloed has its
associated LED flash on and off, while the
LED of the non-soloed channel is not lit.
Bypass Function
To enter the bypass mode, press and hold
the mute all button for 2 seconds. All LEDs
will stop lighting, except those associated
with mute all and A/B output select. The
mute all LED will activate with a “double
flash” pattern to indicate that bypass is
active. Depending on how the system was
configured, the A/B output button may, or
may not, function during bypass mode.
Note if the bypass function has been
disabled, pressing and holding the mute
all button will have no effect.
To exit the bypass mode, press and hold
the mute all button for 2 seconds. Normal
operation will then resume.
