For convenience, you may want to wire
your facility to allow easy access to the
talent amplifi er signal at all locations
where talent amplifi ers might be used.
The talent amplifi ers connect to the Model
55 in parallel, so the connectors on the
distribution panels or mult boxes must
be wired in parallel.
Warning: Do not connect the Model
55’s talent amplifi er output to anything
but Studio Technologies’ talent ampli-
fi ers. Some audio equipment may be
damaged by the +23 Vdc contained on
pin 2 of the talent amplifi er output
connector.
Several mounting options are available for
the Model 35 Talent Amplifi er. For details
refer to Mounting Options in this section.
In special cases you may need to obtain
a stereo, balanced line level output signal
from the Model 55 talent amplifi er output.
The Model 70 Interface is available for this
purpose. For details refer to the end of this
section.
Locating the Model 56 Control Console
The Model 56 was designed for desktop
use, however provision has also been
made for microphone-stand mounting.
For details refer to Mounting Options in
this section.
Connecting the Model 55 to the
Model 56
A standard 5-conductor MIDI-style cable
is used to connect the Model 55 to the
Model 56; a cable is included with your
system. Just connect the cable between
the female 5-pin DIN-type connectors
on the back of the Model 55 and 56, and
you’re done.
Note: If you require a longer cable, be
certain to buy a MIDI cable that has all fi ve
pins wired. If they aren’t all connected, the
Model 56 will not operate. This is because
the Model 55 powers the Model 56 with the
pins that aren’t used for MIDI data.
For best performance, the cable that
connects the Model 55 with the Model
56 should be limited to 50 feet (15.3 m).
Should you need to exceed this length,
refer to the Technical Notes section of
this guide for details on the cable
requirements.
For more information on MIDI, and using
controllers other than the Model 56, please
refer to Appendix A.
AC Mains Power
The Model 55 is internally confi gured
to operate from either 100, 120, or
220/240 V, 50/60 Hz. In most cases,
units shipped to North America are factory
selected for 120 V operation. Units bound
for Japan are selected for 100 V, while
our friends “down under” and in Europe
receive units set for 220/240 V. Before
connecting the Model 55 to mains power,
check that it is confi gured to match the
local mains voltage. Look on the back
panel, adjacent to the power entry connec-
tor, for the confi gured voltage(s). Note than
an incorrect confi guration 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 55 uses an IEC standard
connector 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:
