System Installation & Connection

3-1 General Description
IT-12 Interpreter System has a compact dimension and is easy for installation. IT-12D interpreter consoles are connected in daisy chain and the first IT-12D is connected to the main unit IT-12M.
A detailed description of IT-12 Interpreter System installation and connection will be given by diagrams and examples in this chapter.

3-2 System Connection // Connection Cables
All consoles are connected via D-Sub 25-pin cable. A 25-pin 3 meter cable (with a plug and a socket) is included in each IT-12D Interpreter Console to connect the interpreter unit to Main Unit IT-12M or to each other. On the rear panel of IT-12D there are two D-Sub connecters, the “INPUT” is a plug and the “OUTPUT” a socket. Connect the plug from the 25-pin cable to the Main unit IT- 12M then the socket from the 25-pin cable to the plug “INPUT” on the first Interpreter Console. And then connect the plug of the second 25-pin cable to the socket “OUTPUT” of the first Interpreter Console and the socket is connected to the plug “INPUT” of the next Interpreter Console. Then all the interpreter units are connected in daisy chain. As many as 11 interpreter units can be connected for 12 languages (including floor channel) interpretation. Extension cables can be used between Interpreter Consoles and Main Unit IT-12M (IT-12-C3/C6/C12/ C18).
It is strongly recommended to use JTS tailor-made cables to ensure the best performance.

3-3 Connection of Audio Cables
Cable connection plays an important role in the long distance audio transmission.
Improper connection will result in interference. For example:
(1)Connection for Unbalanced to Balanced transmission cable:
Practical example: after the audios from signal source of mono RCA output, they go through to the IT-12M balanced input “LINE IN” (φ6.3mm jack) via unbalanced output.

35. GND(SHIELD) shielded net
36. BAL. + OR UNBAL.HI.
37. BAL. – OR UNBAL.LO

• Note: This connection is not applicable to Balanced to Unbalanced transmission.
  Otherwise, the signal source of balanced output may be damaged.
  (2)Connection for Balanced to Balanced transmission cable:
  Practical example: After the audios from wired and/or wireless microphones are mixed via the mixer, they go through to the IT-12M balanced input “LINE IN” (φ6.3mm jack) via balanced output.

(3)Connection for Unbalanced to Balanced XLR transmission cable:
Practical example: the recording output of IT-12M “REC. OUT” (unbalanced output) to PA system or media recording input XLR interface (balanced input).

• Note: This connection is not applicable to Balanced to Unbalanced transmission.
  Otherwise, the signal source of balanced output may be damaged.

   Select the Console with one of the Channel Output key ‘1, 2… 11”; for example: If you want this unit to be NO. 1; just press “1”. Then the indicator on the key will light
   on in green while the channel is not occupied. If the indicator on the key flashes in red that means the channel is occupied by other units. When the MIC. ON/OFF of the activated channel is at OFF state, the activate channel could be released when other interpreter console selects the same channel number.

2. LOCK Mode: Interpreter Console Output Channel Select (IT-12D)
   Interpreter Console must be assigned with one unique output channel before being used. The procedure is as:
   a. Make sure the connection is correct, and then turn on the IT-12M.
   b. Turn the “SET” setting switch from “OFF” on the rear panel of the Interpreter Console to “ON”, the indicators of “ENTER” on the unit starts flashing. The indicators of available channels will turn RED. Pay attention only one channel can be activated.
   c. Assign the Console with one of the Channel Output key “1,2….11”, for example: If you want this unit to be NO 1, just press “1”. Then the indicator on the key will change to Green light, press “ ENTER ” key to store, the indicator of “ ENTER ” will keep light on;
   d. Turn the “SET” setting switch to “OFF”, the “ENTER” indicator will turn off, that means the output channel selecting procedure is completed;
   e. If cross interpretation is needed OPEN mode should be selected.
   f. Repeat the same procedure (Steps b~d) to assign all the Interpreter Consoles.

3. To Cancel Selected Output Channel (only for LOCK mode)
   a. Turn the “SET” from “OFF” to “ON”.
   b. Push the “ENTER” for 3 seconds. Then all Channel Output Indicators will turn off.
   c. Turn the “SET” from “ON” to “OFF”. The Console will be of factory setting now.

4. The Operation of IT-12D Interpreter Console:
   The Interpreter Console is designed with digital technologies and used in conjunction with interpreter headset. Each Console allows two interpreters to work on it. The operation procedures are as follows:
   a. At LOCK mode, when the output channel is selected an interpreter only need push the MIC ON/OFF key to activate the microphone or deactivate it.
   b. At OPEN mode, an interpreter can press any Output Channel key to deliver the correspondent language. The available channel will show a green indicator. A flashing red indicator means the channel is occupied.
   c. Put on the headset, adjust the microphone to an appropriate position and control the volume (Floor language is “ORIGINAL” as defaulted). Press “MIC. A/B ON/ OFF” to start the interpretation.
   d. In case the interpreter doesn’t understand the floor language. He/she can select a language familiar with from other interpreter for relay interpretation. First press “RELAY” key, the indicator will be on, and then switch the MONITOR to choose a familiar language for interpretation.
   e. In case the Interpreter wants to cough, keep pressing “COUGH CUT” key to cut off the language output, release it to continue the interpretation.
   f. When the speaker speaks too fast for the interpreter to follow, the interpreter can press “SLOW” key to remind the speaker to slow down. A pulse signal will come out as remind from the IT-12M to the speaker desk.
   g. Each Interpreter Console accommodates A/B two interpreters to work, the operation A/B interpreter is the same.
