through connector on that talent amp send-
ing the signal on to the next talent amp.
For convenience, you may want to wire
your facility to allow easy access to the
talent amplifier signal at all locations where
talent amplifiers might be used. The tal-
ent amplifiers connect to the Model 50 in
parallel, so the connectors on the distribu-
tion panels or mult boxes must be wired in
parallel.
Warning:
Do not connect the Model 50’s
talent amplifier output to anything but
Studio Technologies’ talent amplifiers.
Some audio equipment may be dam-
aged by the +23Vdc contained on pin 2
of the talent amplifier output connector.
Several mounting options are available for
the Model 35 and 38 Talent Amplifiers. For
details refer to the Mounting Options sec-
tions in the Advanced Installation Topics
section of this user guide.
In special cases you may need to obtain
a stereo, balanced line level output signal
from the Model 50 talent amplifier output.
The Model 70 Interface is available for this
purpose. For details refer to the Advanced
Installation Topics section later in this guide.
Locating the Model 51 Control Console
The Model 51 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 50 to the Model 51
A standard 5-conductor MIDI-style cable
is used to connect the Model 50 to the
Model 51; a cable is included with your
system. Just connect the cable between

(Switchcraft No. 297, Neutrik NP3C, or equivalent)
a nominal level of +4dBu, and is capable
of driving loads of 2k ohms and greater. A
¼-inch 3-conductor plug should be wired
with tip for the left output, ring for the right
output, and sleeve for common.
Mic Module Input
A ¼
-inch 3-conductor phone jack, labeled
Mic Module, is located on the back panel.
In most cases the Mic Module input will
not be used, and no plug should be insert-
ed. For details on using the Mic Module
input, refer to the Advanced Installation
Topics section later in this guide.
Talent Amplifier Output
Up to four Model 35 or Model 38 Talent
Amplifiers can be connected in any com-
bination to the Model 50’s talent amplifier
output. The output connector is a 3-pin
male XLR-type. For best performance, use
low-capacitance shielded microphone-
type cable to distribute the talent amplifier
signal. If you have a choice, select cables
with the heaviest wire gauge commonly
available. This will reduce voltage drop
when using long cable runs. Refer to the
Technical Notes section for additional
information.
The simplest installation would use a
microphone cable to connect the Model
50 to the first talent amplifier; the loop
