STAND-ALONE OPERATION WITH ONE INTERPRETED LANGUAGE
The following instructions describe the first setup steps for using the Interpreter Control
Unit PL ICU 22in the most basic scenario – interpretation from one language (most
often English) into one foreign language. Additional options are described in the
following pages.
1. Plug the cord from the external power supply into the power connector (labeled
12 VDC) on the rear panel of the Interpreter Control Unit and plug the AC cord
into an AC power outlet. A surge protector is recommended for protection of the
equipment. The unit is now turned on, and the indicator lights on the top should
illuminate at this time.
2. Plug one or both interpreter microphone(s) into the MIC IN jack(s) on the rear
panel. The connector is a 3.5mm jack (aka a “mini jack”). Use an adapter if your
microphone does not fit. The unit works best with condenser microphones, but
can handle all types of microphones.
3. Make sure the headphone volume knob(s) are turned all the way down, and then
plug in one or both interpreter headphone(s) into the HEADPHONE OUTPUT
jack(s) on the rear panel. The connector is a 3.5 mm jack (aka a “mini jack”). Use
an adapter if your headphone does not fit.
TIP: HEADHPONE/MICROPHONE COMBINATION HEADSETS (SOLD
SEPARATELY) WORK BEST AND ARE PREFERRED BY MOST INTERPRETERS.
4. Connect your original audio source, i.e. the floor feed, into the OR IN input on the
rear panel. The connector is XLR female. Use an adapter if your sound system or
mixer does not use XLR-style connectors. It is now possible to adjust the
incoming volume using the OR IN selector on the rear panel. Ideally, listen on the
headphone, with the headphone volume control knob in a medium position and
then adjust the OR IN selector so that the volume is loud enough, but not too
loud, which could cause distortion. That way, each interpreter has plenty of room
to increase the individual volume controls based on personal preference.
5. Connect a transmitter or other language distribution device (sold separately) to
output A. The connector is XLR male. Use an adapter if your transmitter does not
use XLR-style connectors. Select the FOREIGN switch on the front and turn on
a microphone. It is now possible to adjust the outgoing microphone volume
using the MIC GAIN selector on the rear panel. Ideally, listen on a receiver (sold
separately), with the transmitter tuned to the proper frequency, with the receiver
volume in a medium position. Then adjust the MIC GAIN selector so that the
volume is loud enough, but not too loud, which could cause distortion. That way,
each attendee with a receiver has plenty of room to increase his or her individual
volume based on personal preference.
