You might wonder why you have to press
and hold the reference button for 5 sec-
onds before the selected value is stored.
This is provided specifically so that some
turkey won’t accidentally change the
reference level while they are playing
around in the configuration mode! Only
if you know the “secret” will you be able
to store a new value.
Remote Input Select
The remote input select function requires
configuring two parameters: mode and
input to be selected. The mode can be
selected from three choices: disabled,
exclusive, and nonexclusive. As expected,
when configured for disabled, the function
can not be activated. When configured for
exclusive, whenever the function is acti-
vated only the specified input will be ac-
tive. When configured for nonexclusive,
whenever the function is activated the
specified input will be added (summed)
with any other input or inputs that are
already active.
Remote Mute All
Two configuration choices are associated
with the remote mute all function: disabled
and enabled. To utilize the function simply
configure it for enabled.
Remote Dim
Two configuration choices are associated
with the remote dim function: disabled and
enabled. To utilize the function simply
configure it for enabled.
Spare Remote Input
This remote control input is reserved for
future use. Enabling or disabling this input
will not impact system performance.
Dim Level
The dim function is used to reduce the
monitor output level by a preset amount.
The reduction is in dB relative to the moni-
tor output’s current level. There are four
dim level values available: 10, 15, 20, and
25dB.
Mono Mode
The mono operating mode can be se-
lected from two choices: mono-to-left-and-
right or mono-to-center. For music mixing
it’s common to have a mono function
combine (sum) the signals from the left
and right channels and route the result to
both the left and right output channels. For
broadcast and cinema use, it may be more
appropriate to combine the left and right
signals and route the result to the sur-
round output’s center channel. By default
mono is set to the mono-to-center mode.
Mono Attenuation
To meet the needs of the operator and
specific program content, an attenuation
level when mono is active can be config-
ured. The choices are 0, 3, 4, and 6dB.
Selecting 0dB is equivalent to the attenua-
tion function being disabled, resulting in no
attenuation when mono is selected. This
is provided for those special cases when
the mono mode is set to mono-to-center
and no phase coherent signals are ex-
pected to be part of the left and right
channels. Not generally appropriate for
music mixing, it may find use in broadcast
and cinema applications. 3dB and 4dB are
good choices for the mono-to-center mode
when monitoring mixes that have signifi-
cant phase coherence, such as music
sources. 6dB is provided for compatibility
with the mono function found on many
audio consoles. As the factory default, an
attenuation value of 3dB was selected.
