1.System Introduction
•The Enersound CU-12 Control Unit works as a main unit to provide power, input and output interface,
and control for up to 11 dual interpreter consoles. It allows up to 22 interpreters to perform simultaneous
interpretation for a maximum of 11 target languages plus one floor (original) language.
•The Enersound IC-12 is a 12-channel dual interpreter console with relay capabilities. It allows two
interpreters to work together. Interpreters can choose either floor channel to listen to the speaker and
perform direct interpretation or choose the relay mode when the interpreter does not understand the floor
language and listen to the interpretation from a different booth in a language that this interpreter can
understand.
•The IC-12 also allows interpreters to select the outgoing channel depending on the language they are
interpreting into (two-way interpretation), switch on/ off and mute their microphone, and control the
headphone volume.
•The system features a security lock that prevents two interpreters to select the same outgoing channel at
the same time.
•The product is a professional, easy plug and play, stand-alone system that can be integrated with most
infrared (IR) or radio frequency (RF) language discussion systems.

Open Mode it should be in OFF position.
28. MODE Switch (OPEN / LOCK): The MODE switch needs to be selected before powering on
the system. In OPEN mode an interpreter can activate any channel at any time as long as it is not
occupied. In LOCK mode the outgoing channel is pre-set .Only one outgoing channel will be
programmed per console (setting procedure: refer to System Installation and System Operation
sections for more details).
29. XLR Microphone Input: Each interpreter unit includes 2 balanced XLR microphone input
sockets with +48V Phantom power. Note: Since this input provides +48V Phantom
power, make sure that the microphone you intend to connect can support this voltage. Do not
connect any other equipment or adapter since damage may occur. Never use unbalanced XLR
connectors (Pins 1 and 3 connected).

3. System Installation
All consoles are connected via a D-Sub 25-pin cable in a daisy chain. On the rear panel of each IC-
12 interpreter console, there are two 25-pin D-Sub connectors, “INPUT” (Male) and “OUTPUT”
(Female).
1. Connect the plug (male end) from the 25-pin cable to the Control Unit CU-12. Then connect the
socket (female end) from the 25-pin cable to the “INPUT” on the first Interpreter Console. After
that, connect the plug of the second 25-pin cable to the “OUTPUT” of the first Interpreter Console
and the socket to the “INPUT” of the next Interpreter Console.
2. Follow the same procedure until all interpreter consoles are connected. A maximum of 11
interpreter units can be connected, allowing up to 22 interpreters to perform simultaneous
interpretation for a maximum of 11 target languages plus one floor (original) language. Each
Interpreter Console accommodates two interpreters to work in pairs for the same language
combination in the same booth.
Note: Extension cables can be used between Interpreter Consoles and/or Control Unit. Always
use 25-pin high quality cables provided or approved by the manufacturer.

3. Connect the interpreter’s microphones and stereo headsets in their corresponding jacks.
Then turn the headphone volume control all the way down on each interpreter console.
4. Plug a line level audio signal from the floor language source into the Floor Input ¼’’ Jack
on the rear panel of the Control Unit (Also called ORIGINAL INPUT). Make sure there is
audio coming from this source for testing purposes.
5. Assign a language to each output channel. Example: CH1 is English, CH2 is Spanish, CH3
is French. For each console, we recommend attaching self adhesive or magnetic labels
above the corresponding outgoing channel switch with the names of the two languages
used in that specific console for easy visualization.
6. Connect any RF (FM) or IR wireless transmitter for language 1 to the CH1 output jack on
the control unit. Do the same for all the other channels to be used. Set up the transmitters
according to its instructions. If using Enersound T-500 FM transmitters, connect each
channel output on the IC-12 control unit to the INPUT 1 or INPUT 2 of the corresponding
T-500 Transmitter using either an RCA male to ¼” plug cable (Input 1 on transmitter ) or
RCA to RCA cable (Input 2 on transmitter). Important: INPUT 1 switch on T-500
transmitter must be set to “LINE”. Use one FM T-500 transmitter per language.
7. Plug the control unit’s line cord into an AC power outlet (100 to 240 V, 50-60Hz) and turn
on the control unit.
8. In Open Mode, (make sure the Mode switch is in open position and the Set switch is in the
off position) select the desired outgoing channel on each interpreter console. In Lock
Mode, the outgoing channel is preset. (See 4. System Operation below).
9. On each interpreter console, select the FLOOR channel key so the interpreter can listen to
the floor audio for normal interpretation or the RELAY key for relay interpretation when
the interpreter does not understand the language spoken on the floor.
10. Have the interpreters who will be using the consoles to listen to the headphones and slowly
turn up the volume until the Floor audio is at the lowest comfortable level.
11. Turn the interpreter microphone on by pushing its Mic On/Off button.
12. Have the interpreter speak into the microphone at a natural level. A microphone headset is
recommended to maintain a constant distance between the interpreter’s mouth and the
microphone.
13. Ensure the audio indicator for that specific channel on the control unit is flashing and you
are able to hear the signal with a receiver. Adjust the transmitter input level control if
necessary. 4
Place the microphone at the corner of the
mouth so that it rests at about 1 inch away
from the face. This will avoid noises
generated from the interpreter’s breathing
and air blown while speaking.
Do not place it in front of the mouth!

4. System Operation
4-1 Open Mode
This is the most widely used mode and will suit the majority of your interpretation needs.
For the system to operate in Open Mode, the Mode switch must be in the OPEN position and
the Set switch must be in the OFF position.
When the interpreter selects the desired outgoing channel, the light indicator will turn green
while the channel is not occupied. If the key indicator flashes red when pressing the outgoing
channel key, it means that the channel is occupied by another unit and the interpreter has to wait
until the other interpreter occupying the channel either releases the channel or turns off their
microphone. Note: If the microphone is OFF, the active channel will be released if an interpreter
from another booth selects the same channel.
If there is a need to deselect the active outgoing channel, press the Enter/ Clear key.
When the output channel is selected, the interpreter must push the MIC ON/OFF key to
activate or deactivate the microphone. To momentarily mute the microphone, the interpreter
can press and hold the “MUTE” key.
If the SPEAK SLOWLY function is correctly installed with additional external equipment, when the
speaker speaks toofast for the interpreter to follow,the interpreter can press the “SLOW” key to
remind the speaker to slow down. A 1 second 12V Pulse will come out from the control unit CU-
12 to activate the external notification system.
The example below will help to explain how to operate the system in a conference setting
using interpreter consoles in open mode with “direct” and “relay” interpretation.
Note: It is always necessary to utilize a PA System (Sound System) in conjunction with the
interpretation system so that any speech to be interpreted can be sent to the interpretation
consoles via the FLOOR input.
•Event type: Trilingual conference in the U.S.A with direct and relay interpretation
•Main language: English
•Other languages: Spanish and French
•Number of interpretation booths: 2 (one interpreter console IC-12 per booth)
•Booth #1: “Spanish” Booth from “English into Spanish” and from “Spanish into English”
•Booth #2: “French” Booth from “English into French” and from “French into English”
•Assigned channels: English=CH1 Spanish=CH2 French=CH3
Scenario 1- The speaker talks in English or the audience asks a question in English:
The Spanish interpreter will perform direct interpretation into Spanish. Her outgoing channel
selector should be in CH2 (Spanish) so that her voice is routed to the Spanish channel.
She will listen to the original floor audio; therefore, her “FLOOR” Channel Key should be
selected.
The French interpreter will perform direct interpretation into French. Her outgoing channel
selector should be in CH3 (French) so that her voice is routed to the French channel.
She will listen to the original floor audio; therefore, her “FLOOR” Channel Key should be
selected.
Scenario 2- The speaker talks in Spanish or the audience asks a question in Spanish:
The Spanish interpreter will perform direct interpretation into English. Her outgoing channel
selector should be in CH1 (English) so that her voice is routed to the English channel. She
will listen to the original floor audio; therefore, her “FLOOR” Channel Key should be
selected.

8

The French interpreter will perform relay interpretation into French. Her outgoing channel
selector should be in CH3 (French) so that her voice is routed to the French channel. Since
she does not understand Spanish, she will listen to the relay audio (English) from the other
interpreter booth. Her “RELAY”Channel Key should be selected and the rotary relay
channel selector should be in CH1 (English). Note: If the French interpreter understands
Spanish, she can perform direct interpretation into French listening directly from the “Floor”.
Scenario 3- The speaker talks in French or the audience asks a question in French:
The Spanish interpreter will perform relay interpretation into Spanish. Her outgoing channel
selector should be in CH2 (Spanish) so that her voice is routed to the Spanish channel. Since
she does not understand French, she will listen to the relay audio (English) from the other
interpreter booth. Her “RELAY” Channel Key should be selected and the rotary relay
channel selector should be in CH1 (English). Note: If the Spanish interpreter understands
French, she can perform direct interpretation into Spanish listening directly from the “Floor”.
The French interpreter will perform direct interpretation into English. Her outgoing channel
selector should be in CH1 (English) so that her voice is routed to the English channel.
She will listen to the original floor audio; therefore, her “FLOOR” Channel Key should be
selected.
4-2 Lock Mode
This mode is used in special cases when there is one-way interpretation (i.e. the interpreter
will always interpret into one foreign language).
Each Interpreter Console IC-12 must be preset with a unique outgoing channel before being
used. The procedure is as follows:
a. Slide the Mode switch on all the interpreter consoles to the Lock position.
b. Make sure all connections are correct, and power on the control unit CU-12.
c. Slide the “SET” switch on the rear panel of the Interpreter Console to the “ON” position.
The “ENTER” light indicator on thatunit will start flashing. The available channels indica-
tors will turn RED. Only one unassigned channel can be activated per console.
d. Press one of the available outgoing channel keys and then press “ENTER” to save the
selection. For example: if you want this unit to be assigned to CH1, press the outgoing key
“1”. Then the indicator on the key will change to green. Press the “ENTER” key to save
your selection.
e. Turn the “SET” switch to the “OFF” position. The “ENTER” indicator will turn off and the
output channel selecting procedure will be completed.
f. Repeat the same procedure (Steps c~e) to assign all the Interpreter Consoles.
To Cancel Selected Output Channel (only for LOCK mode)
a. Turn the “SET” switch to the “ON” position.
b. Push the “ENTER” key for 3 seconds. Then all Outgoing Channel Indicators will turn off.
c. Turn the “SET” switch to the “OFF” position. The Console will be reset to factory default
