for Surround
monitor output of an audio console. During
surround mode operation, the monitor
outputs associated with the left and right
channels are connected, via electrome-
chanical relays, to the Model 58’s output
circuitry. When the bypass function is
enabled, the left and right monitor outputs
disconnect from the Model 58’s output
circuitry, connecting instead to the bypass
inputs; the other monitor output channels
mute. Activation of the bypass function
can be by means of a button on the Model
59 Control Console, or remotely using a
signal connected to contact input 2.
Installation
In this section you will be installing the
Model 58 Central Controllers in an equip-
ment rack. Model 58 units will be intercon-
nected using a ribbon-cable bus assembly.
Audio input, insert, and output connections
will be made. A location will be selected
for the Model 59 Control Console, and it
will be connected to one of the Model 58
units. If required, external equipment will
be interfaced with the remote control
inputs. AC mains power will be connected
to the Model 58 units.
System Components
The main shipping carton contains the
Model 58/Model 59 base configuration.
This consists of one each of the following:
Model 58 Central Controller, Model 59
Control Console, 20-foot (6.1m) 9-pin
D-subminiature interconnecting cable,
ribbon-cable bus assembly, User Guide,
and warranty card. Units destined for
North America also include an AC mains
cord. Your dealer or distributor will provide
an AC mains cord for non-North American
destination. Each additional Model 58
Central Controller is shipped in a separate
carton. These Model 58 “solo” units in-
clude a warranty card and, where appli-
cable, an AC mains cord.
Mounting the Model 58
Central Controllers
Each Model 58 Central Controller requires
one space in a standard 19-inch (48.3cm)
equipment rack. Select a location that is
convenient to both the analog audio sig-
nals and the Model 59 Control Console.
A 20-foot (6.1m) cable is supplied to
connect one of the Model 58 units to the
Model 59. You can supply your own inter-
connecting cable, however 50 feet (15.3m)
is the recommended maximum length.
Secure each Model 58 in the equipment
rack using two mounting screws per side.
Consider selecting a mounting location
that can accommodate future expansion.
If, for example, you are installing three
Model 58 units to create a 6-channel
system, you may want to leave room in the
rack for one additional Model 58. This will
make upgrading to an 8-channel system
simple; install a fourth Model 58 and
you’re ready to go.
Interconnecting the Model 58
Units
In most applications multiple Model 58
units are going to be used together to
create a multi-channel monitor system.
To assist in this purpose, a ribbon-cable
bus assembly is provided with each
Model 58/Model 59 base configuration.
The bus assembly contains four 9-pin
D-subminiature (D-sub) plugs, spaced
2 inches apart, allowing up to four Model
