In special cases you may need to obtain
a stereo, balanced line level output signal
from the Model 55 talent amplifier 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 5
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 (15.3m).
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 configured to
operate from either 100, 120, or 220/240V,
50/60Hz. In most cases, 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 55
to mains power, check that it is configured
to match the local mains voltage. Look on
the back panel, adjacent to the power
entry connector, for the configured
voltage(s). Note than an incorrect configu-
ration could seriously damage the unit.
Should it be necessary to change the
unit’s operating voltage it must be per-
formed only at the factory or by an autho-
rized service technician.
The Model 55 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 55 does not
contain an AC mains disconnect switch.
As such the mains cord plug serves as
the disconnection device. Safety consid-
eration requires that the plug and associ-
ated outlet be easily accessible to allow
rapid disconnection of mains power
should it prove necessary.
