Data Sheet

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 monitor
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 simultaneously 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. Chan
-
nel pop solo allows the level of a single 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 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 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 func
-
tion is used to create a stereo signal from the selected surround (5.1) source. Key operating parameters in the surround to stereo
downmix 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 monitored on the center output channel. The two downmix functions can be simul-
taneously 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 functions, talkback or slate activity from an audio console or other communications
system can control the level of the post-fader surround and stereo monitor outputs.
