LFE content before routing the sum to the
subwoofer output.
The post-fader surround and stereo moni-
tor 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 surround and
stereo monitor output levels can be set to
a pre-configured value. This is provided for
audio-with-picture applications that require
a specific monitor output level. The refer-
ence level is easily configured by taking an
electronic “snapshot” of the desired moni-
tor output level. For operator 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
surround and stereo 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 moni-
tor output channels to be simultaneously
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 in monitoring audio material.
Channel pop solo allows the level of a sin-
gle post-fader monitor output channel to be
raised while the level of the other channels
is reduced. This helps to emphasize the
content on one channel without fully mut-
ing 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 channels. The amount of
level increase—the “pop”—as well as the
amount of attenuation 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 required. The stereo to mono downmix
function allows audio on the left and right
channels to be added (summed) and moni-
tored on the center output channel. The
two downmix functions can be simultane-
ously enabled, allowing a surround source
to be checked for mono compatibility. The
downmix 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,
and audio consoles. Two remote-control
inputs provide access to the mute all and
dim functions. By providing access to these
