BI-DIRECTIONAL OPERATION WITH TWO INTERPRETED LANGUAGES
At this time, you are operating the Interpreter Control Unit
PL ICU 2

in the most basic
way – interpretation from one source language into one foreign language.
Using only one Interpreter Control Unit, you can add an additional transmitter (sold
separately) and thus provide bi-directional interpretation on two channels. For example,
interpretation not only from English into a foreign language, but also from the foreign
language back into English is possible.
Simply connect a second transmitter to the output OUT B via XLR-style connectors.
OUT B corresponds to the ENGLISH selector on the front. The interpreters can now
decide into which language they interpret at any given time. For example, if English is
spoken on the floor, interpreters interpret from English to the foreign language and
select FOREIGN. Their interpretation goes out on output OUT A, which is transmitted
on the first selected frequency. Foreign-language listeners tune into that frequency on
their receivers.
If the floor language changes to the foreign language, then the interpreters now interpret
from the foreign language into English. Therefore, they select ENGLISH. Their
interpretation now goes out on output OUT B, which is transmitted on the second
selected frequency. English listeners tune into that frequency on their receivers.
MULTIPLE LANGUAGES FROM ONE SOURCE LANGUAGE WITHOUT RELAY
If interpretation back into the source language is not required, but interpretation into
multiple foreign languages is required, the combination of multiple Interpreter Control
Units

is ideal.
Using additional Interpreter Control Units and additional transmitters, it is possible to
provide interpretation from one floor language (e.g. English) into an unlimited number of
foreign languages by “daisy-chaining” multiple Interpreter Control Units.
Simply use an XLR PL ICUble (sold separately) to provide a sound feed from the first
Interpreter Control Unit to the next one by connecting the XLR PL ICUble to output OUT
B of the first unit and then into the input OR IN of the second unit. Basically, the first unit
functions as the audio feed for the second one. Connect transmitters to each
subsequent unit, as described above for stand-alone operation.
Ensure that all interpreters have their listening selectors set to OR. Also ensure that all
the pass-through selectors are ON (otherwise, no sound can be transferred from one
unit to the next). Use the OR GAIN selectors on each unit to fine-tune the incoming
sound levels of each Interpreter Control Unit.
You can continue this chain indefinitely.
