Data Sheet

The dim function allows the post-fader monitor output level 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 monitor output channels to be simultaneously
muted. The input mute/solo section allows an input channel to be muted or monitored as desired. Multiple channels can also
be simultaneously selected for muting or “soloing.”
Two output mute functions are also provided. One button allows the seven main channels of the post-fader monitor output to
be muted. A second button allows the subwoofer (SUB) channel of the post-fader monitor output to be muted. The output mute
functions, along with the input mute/solo function, allow a user complete flexibility when checking an input source and its path
to the loudspeaker system. These mute and solo resources are crucial in a multichannel environment, especially when signals
are passing through the bass management function.
Three downmix functions allow the selected input source to be checked for compatibility with common audio channel formats.
This can help ensure that surround and stereo mixes correctly “fold down” into formats that utilize less channels than the original.
Errors can be quickly identified and then corrected. The downmix functions, To 5.1 and To Stereo, apply only to the two surround
(7.1) sources. The To Mono downmix function applies to the surround and stereo inputs. Several of the downmix parameters can
be configured to best meet the needs of an application. The downmix functions always impact the post-fader monitor output. A
configuration setting allows the pre-fader 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 monitor outputs.
