As soon as mains power is applied, the
power-present LED on each of the Model
58s will light. The Model 59 will go through
its power-up sequence lighting each LED
in a rapid sequence.
Note that any time a Model 58 configura-
tion DIP switch is changed, mains power
on all Model 58 units must be discon-
nected and reconnected. This ensures
that the logic circuitry is fully reset to
match the new operating parameters.
(This is not a bug in software—we de-
signed it this way to ensure that perfor-
mance would always be correct!) Refer to
the Configuration section of this guide for
details on setting the DIP switches.
Configuration
After the physical installation has been
completed, several configuration issues
must be addressed. On the Model 58
Central Controllers, the unit ID and operat-
ing mode must be set. In addition, the
main input, insert return, and monitor
output signal levels must be calibrated
using trim potentiometers. As a final step,
the operating parameters of the system
will be set using the Model 59 Control
Console’s configuration mode.
Note that any time a Model 58 DIP switch
is changed, the data LED (located to the
right of the switches) will flash. This is
normal, being provided for factory confir-
mation of switch operation.
Model 58 Unit Identification
Numbers
A unique unit identification (ID) number
must be assigned to each Model 58. This
allows commands from the Model 59
matter which Model 58 is selected, it is
often best for clarity to use the Model 58
that is going to be configured with unit ID 1.
AC Mains Power
The Model 58 is internally configured to
operate from either 100, 120, or 220/240V,
50/60Hz. Units shipped to North America
are factory selected for 120V operation.
Units bound for Japan are selected for
100V, while our friends “down under” and
in Europe receive units set for 220/240V.
Before connecting the Model 58 to mains
power, check that it is configured to match
the local mains voltage. Look on the back
panel (adjacent to the power entry connec-
tor) for the configured voltage(s). Note than
an incorrect configuration could seriously
damage the unit. Should it be necessary to
change the unit’s operating voltage it must
be performed only at the factory or by an
authorized service technician.
The Model 58 uses an IEC standard con-
nector to mate with the AC mains cord.
The wire colors in the AC mains cord
should conform to the internationally
recognized CEE color code and must
be wired accordingly:
Connection Wire Color
Neutral (N) Light Blue
Line (L) Brown
Protective Earth (E) Green/Yellow
Safety Warning: The Model 58 does
not contain an AC mains disconnect
switch. As such, the mains cord plug
serves as the disconnection device.
Safety consideration requires that the
plug and associated outlet be easily ac-
cessible to allow rapid disconnection of
mains power should it prove necessary.
