Introduction
What This User Guide Covers
This User Guide is designed to assist
you when installing and using the Model
780-03 Central Controller and one or more
associated Model 790 or Model 71 Control
Consoles.
Overview
Creating and distributing eight channel
(7.1) surround audio material has become
common for entertainment, cinema, and
allied applications. As such, the ability
to simply and effectively monitor these
sources is imperative during the record-
ing and post-production process. Studio
Technologies has addressed these needs
with the StudioComm for Surround Model
780-03 Central Controller and the Model
790 and Model 71 Control Consoles. With
digital audio inputs, digital and analog
monitor outputs, support for multiple user
control surfaces, and an extensive set of
resources it’s a simple task to integrate a
monitoring system into virtually any facility.
The carefully selected group of features,
including two surround (7.1) and one ste-
reo input, configurable input-source time
delay, LFE low-pass filter, multiple pre- and
post-fader surround outputs, configurable
downmix and mute/solo functions, and
bass management, along with a multi-for-
mat 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 790 Control Console. It’s
the system’s “command center” and is de-
signed to reside at a user’s location,
allowing fingertip selection of all monitoring
functions. Numerous LEDs provide com-
plete status information. A 4-digit numeric
display indicates the level of the post-fader
digital and analog monitor outputs. A major
strength of the Model 790 is its ability to
configure, under software control, many
important operating parameters. Intended
for secondary monitoring locations that
don’t require all of the Model 790’s fea-
tures, 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
790 Control Console. However, up to three
additional Model 790 or Model 71 Control
Consoles can also be connected. This
provides multiple users with control over
a facility’s monitor system. And to make
installation simple, the Model 780-03 pro-
vides power for all connected Model 790 or
Model 71 units.
The core of this StudioComm for Sur-
round system is the Model 780-03 Cen-
tral Controller. The one-rack-space unit
contains circuitry that supports balanced
digital audio inputs, balanced digital and
analog monitor outputs, digital audio and
control processing, and interfacing for the
user control surface(s). The Model 780-03
provides two surround (7.1) and one ste-
reo digital audio inputs. These balanced
digital inputs are AES3-compliant; sources
of this type are ubiquitous in many post-
production and audio facility environments.
The inputs allow a sample rate of 44.1,
48, 88.2 or 96 kHz and a bit depth of up to
24 to be supported. Circuitry associated
with the stereo input provides sample rate
conversion (SRC) capability, allowing a
wide range of digital audio sources to be
