Cue (Talk to Phones)
The Model 61 Control Console contains
an internal microphone and enable button
that is used to send voices “cues” to the
talent by means of the headphone outputs.
To improve voice clarity and prevent
acoustic feedback the control room output
level automatically attenuates (dims) upon
activation of the cue microphone. A control
on the Model 60A’s front panel allows
adjustment of the voice level. Also on the
Model 60A’s front panel is a switch that
selects whether the voice cue will replace
(interrupt) or add (sum) with the normal
headphone program source(s).
Auxiliary Switcher
The auxiliary switcher section allows a
wide variety of installer-implemented
functions to be created. Compatible with
stereo, balanced line-level audio signals,
the switcher is entirely passive with no
active electronics. Possible applications
include a 1-input/3-output speaker selector
or a 3-input/1-output source selector.
Installation
In this section you will be installing the
Model 60A Central Controller in an equip-
ment rack. Input and output connections
will be made using the Model 60A’s multi-
tude of jacks. A location will be selected
for the Model 61 Control Console, and it
will be connected to the Model 60A. AC
mains power will be connected to the
Model 60A.
System Components
The StudioComm shipping carton contains
a Model 60A Central Controller, Model 61
Control Console, 5-conductor MIDI-style
cable, User Guide, and warranty card.
Units destined for North America and
Japan are shipped with an AC mains cord.
Your dealer or distributor will provide an
AC mains cord for non-North American
destinations.
Mounting the Model 60A
The Model 60A requires one space in
a standard 19-inch (48.3cm) equipment
rack. Select a location near where the
Model 61 Control Console will be located.
A 10-foot (3.1m) cable is provided to
connect the Model 60A to the Model 61.
You can supply a longer cable, however
50 feet (15.4m) is the recommended
maximum length. It is desirable to locate
the Model 60A to allow easy access to
both the front and the back panels. The
back panel contains the input connections,
most of the output connections, and the
input sensitivity switches. The front panel
contains many switches, controls, and
indicator lights. In addition, the front panel
also contains one of the headphone output
connectors. The Model 60A is secured to
the equipment rack using two mounting
screws per side.
Audio Inputs and Outputs
The Model 60A’s line-level audio input and
output connections are made using ¼-inch
phone jacks. For reliable audio intercon-
nection, the plugs you use must comply
with industry standard RS-453. Switchcraft
No. 297, Neutrik NP3C, or equivalent will
work correctly.
Stereo Line Inputs
The Model 60A provides four stereo line-
level inputs. Each input is electronically
balanced and can be individually config-
ured for compatibility with +4dBu or
–10dBV signal levels. Switches on the
