case, pressing an insert button would
result in no action.
Monitor Output General Functions
Four buttons and one rotary control are
associated with the monitor output func-
tion. The buttons are A/B output select,
reference level, mute all, and dim. The
rotary level control is used to set the
monitor output level.
A/B Output Select
The A/B button is used to select the set
of monitor outputs to be connected to the
Model 58’s output circuitry. Two LEDs are
associated with the button, displaying the
active output. Pressing the button
“toggles” between the A and B outputs.
There is a special configuration that allows
this button to be disabled. This would be
appropriate if connections were made only
to output A. If this configuration has been
selected, pressing the A/B will result in no
action occurring.
Reference Level
The reference level button, labeled REF,
sets the monitor output to a preset level.
This level is normally set by a technician,
using a sound-pressure-level (SPL) meter,
at the time of installation. The LED associ-
ated with the reference level function lights
steadily whenever the function is active.
When reference level mode is active the
rotary level control is disabled, as is the
remote level control if it is connected.
The reference LED also serves as a cali-
bration aid. If the reference level mode is
not active, and the rotary level control is
set at precisely the same level as that
stored for the reference value, the LED
will flash. This also holds true for the
remote level control, if configured.
Mute All
The mute all function is highly complicated
to operate—not! Pressing the mute all
button causes the active outputs (A or B)
to mute using the output relays. The LED
associated with the mute all button will
flash whenever mute all is active. This
would also hold true if mute all is enabled
via the remote mute all function. In this
case the mute all LED would flash, along
with the remote activity LED.
Turning on the mute all function causes
the current operating status to be saved
in the Model 59’s memory. Upon turning
off mute all, the operating status is re-
turned to its previous state. This applies
specifically to the mute/solo, monitor level,
and dim functions.
Dim
The dim function is quite self-explanatory.
Press the dim button to enable the dim
mode, which will reduce the monitor output
level by a preset amount. The dim button
is always set to “latch” the function on and
off. Dim activity applies no matter whether
the level is being set by the rotary control,
the reference button, or, if configured, the
remote level control. The dim level can be
configured for 10, 15, or 20dB, so one of
those values will apply when dim is active.
The LED associated with the dim button
will flash whenever dim is active. This
would also hold true if dim is enabled via
the remote dim function. In this case the
dim LED would flash, along with the re-
mote activity LED.
What’s not so self-explanatory is the auto-
dim-off function. Whenever dim is on and
reference mode is not active, changing the
rotary level control or, if configured, the
remote level control, will automatically turn
