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 communi-
cations system can control the level of the
post-fader surround and stereo monitor
outputs.
Installation
In this section you will be installing the
Model 760-03 Central Controller in an
equipment rack. Connections to the digital
audio inputs, digital monitor outputs, and
analog monitor outputs will be made. A
dedicated digital audio timing reference
signal can be connected to the sync input.
If desired, external equipment will be inter-
faced to the remote control inputs. A loca-
tion will be selected for the first Model 77
Control Console and it will be connected
to the Model 760-03. AC mains power will
be connected to the Model 760-03. For
advanced applications up to three addi-
tional Model 77 or Model 71 Control
Console units can be connected to the
Model 760-03.
System Components
The main shipping carton contains one
each of the following: Model 760-03 Cen-
tral Controller, Model 77 Control Console,
9-pin D-sub interconnecting cable, and
user guide. Also included in the ship-
ping carton is a North-American-standard
AC mains cord. Your dealer or distributor
should provide an AC mains cord appro-
priate for destinations outside of North
America. Any additional Model 77 or Model
71 Control Consoles will be shipped in
separate cartons.
Mounting the Model 760-03
The Model 760-03 Central Controller re-
quires one space (1U) in a standard 19-inch
(48.3 cm) equipment rack. Secure the Model
760-03 into the equipment rack using two
mounting screws per side. Select a location
that is convenient for making connections to
the audio signals as well as interfacing with
the first (or only) Model 77 Control Console.
A cable is supplied to connect the Model
760-03 to the Model 77. If the needs of a
specific installation dictate, an alternate-
length interconnecting cable can be fabri-
cated and used.
Audio Connections
Audio connections are made by way of three
25-pin female D-subminiature connectors
and one 3-pin female XLR connector. All
the connectors are located on the Model
760-03’s back panel. Refer to Figure 2 for
a detailed view of these connectors.
Audio Inputs
Two surround (5.1) and three stereo digi-
tal audio sources can be connected. All
sources can be monitored using the pre-
and post-fader surround and post-fader
stereo monitor output channels. A one-to-
one relationship is maintained between the
input and output channels, i.e., left input to
left monitor output, right input to right moni-
tor output, center input to center monitor
output, etc. (Of course this won’t be true in
the case where the user has enabled one or
both of the downmix functions.) Stereo input
C is also routed to the stereo input C direct
monitor output.
The audio inputs support digital audio sig-
nals with a sampling rate of up to 192 kHz
and a word length (depth) of up to 24 bits.
