Pre-Fader Surround Digital
Monitor Output Mode
The pre-fader surround digital monitor
output can be configured as to its place
in the Model 760-03’s signal flow. The
choices are pre- or post-downmix. In the
pre-downmix mode the digital monitor
output channels will not be impacted by
the state of the downmix functions. This
setting would be appropriate if the pre-
fader surround digital monitor outputs were
being routed to a storage system, routed to
another facility, etc. In this case the action
of a user enabling or disabling the down-
mix functions won’t impact the pre-fader
surround digital monitor output signals. If
the post-downmix mode is selected the
pre-fader surround digital monitor outputs
will reflect the actions of the downmix func-
tions. This choice would be correct if, for
example, level meters were connected to
the pre-fader surround digital monitor out-
puts. In this scenario a user would want to
visually observe the actions that the down-
mix functions impart on the signals.
Channel Pop Solo Mode
Offset Levels
Two parameters can be configured that de-
termine how the channel pop solo function
will impact the output levels of the post-
fader digital and analog monitor outputs.
The up offset level sets the amount of
increase (gain) that a channel will experi-
ence when it is soloed in the channel pop
solo mode. The down offset level sets the
amount of decrease (attenuation) that the
non-soloed channels will experience when
a channel is active in the channel pop solo
mode. Refer to Figure 11 for details.
Post-Fader Digital and Analog
Monitor Output Level Offsets
To provide assistance during room cali-
bration, the relative output levels of the
post-fader surround and stereo digital and
analog monitor output channels can be ad-
justed over a limited range. The eight chan-
nels can be adjusted in 0.5-dB steps over
a ±12-dB range. During configuration the
displayed value represents the dB level dif-
ference as compared to the nominal output
level. In most cases one surround and one
stereo channel should serve as the overall
reference level and not be changed. This
is typically the center channel for surround
and the left channel for stereo. The con-
figured output level offset values apply to
both the digital and analog surround stereo
monitor outputs. It is not possible to config-
ure a specific channel’s digital and analog
monitor output level offsets to independent
values.
This feature is provided primarily for use
when the post-fader monitor output chan-
nels are connected to loudspeaker sys-
tems that don’t offer a means of “trimming”
the input sensitivity of individual channels.
Without this capability, minor adjustments
to the output level of specific loudspeakers
to account for room acoustics wouldn’t be
possible.
It’s also possible to use the StudioComm’s
output level offset capability to adjust the
overall post-fader monitor output levels to
allow matching to the input sensitivity of
loudspeaker systems. In this case all the
channels (six for surround, two for stereo)
would be configured to have the same
output level offset setting. For example, the
six surround channels could all be config-
ured to have a –3.5 dB output level offset.
However, great care must be taken when
