main input channels, combining it with the
LFE content before routing the sum to the
digital and analog subwoofer outputs.
The post-fader surround and stereo digital
and analog monitor output levels can be
controlled by way of a large, easy-to-use
rotary control. The control, actually a digital
encoder, allows level selection in precise
0.5-dB steps. The auto mute all function
causes the post-fader surround and stereo
monitor output channels to automatically
mute whenever the output level control
reaches maximum attenuation. Using the
reference level function, the post-fader sur-
round and stereo monitor output levels can
be set to a pre-configured value. This is pro-
vided for audio-with-picture applications that
require a specific monitor output level. The
reference level is easily configured by tak-
ing an electronic “snapshot” of the desired
monitor output level. For user confirmation a
4-digit LED readout can display the level of
the post-fader surround and stereo monitor
output channels. To match the needs of a
facility, it can be configured to display either
the attenuation level or the sound pressure
level (SPL).
The dim function allows the post-fader sur-
round and stereo digital and analog monitor
output levels to be reduced by a fixed dB
amount. The dim level is configured from
among four available values. A mute all
function allows the post-fader surround and
stereo monitor output channels to be simul-
taneously muted. The channel mute/solo
section provides post-fader surround and
stereo channel monitoring control, allowing
a single channel to be muted or monitored.
Multiple channels can also be simultane-
ously selected for muting or “soloing.”
A special solo mode is also provided, called
channel pop solo, which offers a unique
aid when monitoring audio material. Chan-
nel pop solo allows the level of a single
post-fader digital and analog monitor out-
put channel to be raised while the level of
the other channels is reduced. This helps
to emphasize the content on one channel
without fully muting the others. Broadcast
applications can benefit from the channel
pop solo mode by allowing, for example, the
center channel to be highlighted while still
maintaining some level on the other chan-
nels. The amount of level increase—the
“pop”—as well as the amount of attenua-
tion can be configured to meet the needs of
specific applications or users.
Two functions allow the input sources to be
checked for level or phase inconsistencies.
The surround to stereo downmix function is
used to create a stereo signal from the se-
lected surround (5.1) source. Key operating
parameters in the surround to stereo down-
mix function can be configured to meet the
requirements of an application. This can be
especially useful when support for specific
international broadcast standards is re-
quired. The stereo to mono downmix func-
tion allows audio on the left and right input
channels to be added (summed) and moni-
tored on the center output channel. The two
downmix functions can be simultaneously
enabled, allowing a surround source to be
checked for mono compatibility. The down-
mix functions always impact the post-fader
surround and stereo monitor outputs. A
configuration setting allows the pre-fader
surround monitor output to be selected for
pre- or post-downmix operation.
For flexibility, the StudioComm for Surround
system is designed to easily integrate with
equipment such as production intercom
systems, on-air or recording tally signals,
