Introduction
What This User Guide Covers
This User Guide is designed to assist you
when installing and using the Model 76D
Central Controller and one or more associat-
ed Model 77 or Model 71 Control Consoles.
Overview
As creating and distributing multi-channel
surround (5.1) and stereo audio material
has become a day-to-day reality, the abil-
ity to simply and effectively monitor these
sources is imperative for recording, post-
production, and broadcast facilities. And
with audio-with-picture applications becom-
ing so prevalent, additional monitoring chal-
lenges have arisen. Studio Technologies
has addressed these needs with the Studio-
Comm for Surround Model 76D Central
Controller and the Model 77 and Model 71
Control Consoles. With digital audio inputs,
digital monitor outputs, support for multiple
user control surfaces, and an extensive set
of operating resources it’s a simple task to
integrate a monitoring system into virtually
any facility. The carefully selected group
of features, including surround and stereo
inputs, configurable input-signal time delay,
multiple pre- and post-fader outputs, configu-
rable downmix and mute/solo functions, and
bass management, along with a multi-format
sync input, make the system powerful yet
simple to operate. And by using the best of
contemporary technology, as well as follow-
ing rigorous design practices, the system’s
audio quality is excellent.
A StudioComm for Surround system starts
with the Model 77 Control Console. It’s the
system’s “command center” and is designed
to reside at an operator’s location, allowing
fingertip selection of all monitoring functions.
Numerous LED indicators provide com-
plete status information. A 4-digit numeric
display indicates the post-fader monitor
output level in real time. A major strength
of the Model 77 is its ability to configure,
under software control, many important
operating parameters. Intended for sec-
ondary monitoring locations, the Model 71
Control Console is a compact user control
surface. It provides three of the most basic
functions: a rotary level control, dim on/off
button, and reference level on/off button.
While many installations will use only one
Model 77 Control Console, up to three
additional Model 77 or Model 71 Control
Consoles can also be connected. This pro-
vides multiple users with full control over
a facility’s monitor system. And to make
installation simple, the Model 76D provides
power for all connected Model 77 or Model
71 units.
The core of this StudioComm for Surround
system is the Model 76D Central Con-
troller. The one-rack-space unit contains
circuitry that supports digital audio inputs,
digital monitor outputs, processing, and
the user interface. The Model 76D provides
two surround (5.1) and three stereo digi-
tal audio inputs. These unbalanced digital
inputs are AES3/SMPTE 276M-compliant;
sources of this type are ubiquitous in most
post-production and broadcast environ-
ments. The inputs allow a sample rate of
up to 192 kHz and a bit depth of up to 24
to be directly supported. Circuitry associ-
ated with one of the stereo inputs provides
sample rate conversion (SRC) capabil-
ity, allowing a wide range of digital audio
sources to be monitored. Up to 340 mil-
liseconds of input delay can be selected
to compensate for processing delays in an
associated video path. For flexibility, two
delay values can be configured, allowing
