for Surround
Channel pop solo allows the level of a
single channel to be raised while the level
of the other channel 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, 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 inconsisten-
cies. The 5.1 to stereo downmix function
is used to create a stereo signal from the
selected surround (5.1) source. 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 simultaneously enabled, allowing a
surround source to be checked for mono
compatibility.
In addition to the surround (5.1) monitor
output, a stereo (2-channel) auxiliary moni-
tor output is also provided. A stereo signal,
connected to stereo input C on the Model
76B Central Controller, can be routed to
the auxiliary monitor output. A pushbutton
on the Model 77B Control Console allows
on/off control of the signal; no level control
or signal modification takes place. The aux-
iliary monitor output feature can be useful
in special applications, e.g., in a broadcast
control room setting where an audio signal,
such as site-event cue signals, needs to be
monitored by way of an independent set of
loudspeakers.
For flexibility, the StudioComm for
Surround system is designed to easily
integrate with equipment such as produc-
tion intercom systems, on-air or recording
tally signals, audio consoles, and film
motion-control electronics. Three remote-
control input functions are provided: mute
all, dim, and auxiliary monitor output on/off.
By providing access to these functions,
talkback or slate activity from an audio
console or other communications system
can control the level of the surround moni-
tor output or enable to the auxiliary monitor
output.
Installation
In this section you will be installing the
Model 76B Central Controller in an equip-
ment rack. Connections to the digital audio
inputs and analog monitor outputs will
be made. If desired, a source of Dolby E
metadata will be connected and external
equipment will be interfaced to the remote
control inputs. A location will be selected
for the first Model 77B Control Console
and it will be connected to the Model 76B.
AC mains power will be connected to the
Model 76B.
For advanced applications up to three
additional Model 77B Control Console
units can be connected to the Model 76B.
Please refer to the Advanced Installation
section of this guide for details.
