Introduction
What This User Guide Covers
This User Guide is designed to assist you
when installing and using the Model 760-02
Central Controller and one or more associ-
ated 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 ability to
simply and effectively monitor these sources
is imperative for recording, post-production,
and broadcast facilities. And with audio-with-
picture applications becoming so prevalent,
additional monitoring challenges have arisen.
Studio Technologies has addressed these
needs with the StudioComm for Surround
Model 760-02 Central Controller and the
Model 77 and Model 71 Control Consoles.
With digital audio inputs, analog monitor
outputs, support for multiple user control
surfaces, and an extensive set of operat-
ing resources it’s a simple task to integrate
a monitoring system into virtually any facil-
ity. The carefully selected group of features,
which includes surround and stereo inputs
and output, configurable input-signal time
delay, configurable 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 following 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 a user’s location, allowing fin-
gertip selection of all monitoring functions.
Numerous LED indicators provide complete
status information. A 4-digit numeric dis-
play indicates the monitor output level in
real time. A major strength of the Model 77
is its ability to configure, under software
control, many important operating param-
eters. Intended for secondary 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 refer-
ence level on/off button.
Most installations will use only one Model
77 Control Console. However, up to three
additional Model 77 or Model 71 Control
Consoles can also be connected. This
provides multiple users with full control
over a facility’s monitor system. And to
make installation simple, the Model 760-02
provides power for all connected Model 77
or Model 71 units.
The core of this StudioComm for Surround
system is the Model 760-02 Central Con-
troller. The one-rack-space unit contains
circuitry that supports balanced digital
audio inputs, balanced analog monitor
outputs, digital processing of audio and
control signals, and interfacing for the user
control surface(s). The Model 760-02 pro-
vides two surround (5.1) and three stereo
digital audio inputs. These balanced digital
inputs are AES3-compliant; sources of this
type are ubiquitous in many post-produc-
tion and audio facility environments. The
inputs allow a sample rate of up to 192
kHz and a bit depth of up to 24 to be di-
rectly supported. Circuitry associated with
one of the stereo inputs provides sample
rate conversion (SRC) capability, allowing
a wide range of digital audio sources to be
monitored. Up to 340 milliseconds of input
delay can be selected to compensate for
processing delays in an associated video
path. For flexibility, two delay values can be
