ensures that the calibrated monitor level
won’t accidentally be changed by some
maroon. This, along with a remote activity
LED indicator on the Model 59, keeps the
remote level control from doing more harm
than good.
Installation
In this section you will be installing the one
or more Model 58 Central Controllers in an
equipment rack. Multiple Model 58 units
will be interconnected using the bus as-
sembly. 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 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 the Model 58 units to the Model
59. You can supply your own interconnect-
ing 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-sub plugs,
spaced 2 inches apart, allowing up to four
Model 58s to be interconnected. Refer to
Figure 4 for a diagram depicting the inter-
connection of four Model 58 units. Each
Model 58 contains a 9-pin D-sub connec-
tor labeled LOOP THRU. Use the bus
assembly to link these connectors to-
gether. Locking hardware for the plugs
is not included as it is unnecessary for
