(ATUC-50INT) Up to 6 interpretation units can be connected. The maximum number of 50DU/IU/INT connections is 300

(when three CUs are linked). INTs can only be connected to the primary 50CU. They cannot be connected to extension 50CUs. Digital Conference System ATUC-50 with the additional Interpretation Unit ATUC-50INT enables the following three types,

(1) to (3), of interpretation. This section explains a brief overview of operations assuming that you have set the interpretation languages as in the following table. Audio Group 1 Language Name Audio Group 2 Audio Group 3 English Japanese French

(1) Interpretation using two languages (2 Languages) While in the 2 Languages interpretation mode, you can select from three interpretation patterns (see table below). For instance, when the interpretation pattern English Japanese is set, F appears as the character on the left in the display , and 2 appears as the digit on the right. At this time, the speech from the floor channel is heard through the monitor channel. Additionally, interpreted speech that is input from the microphone of the INT is output to Audio Group 2 (the Japanese group). When the bi-directional interpretation pattern is selected, the interpretation system is established with just this INT1. Pressing the interpretation languages selection button switches the interpretation patterns between Japanese English (Outgoing language A) and English Japanese (Outgoing language B), simultaneously switch the interpreted speech being output. Whichever interpretation pattern you selected, Japanese English

(Outgoing language A) or English Japanese (Outgoing language B), it is not saved. When the system is started, the interpretation pattern is Japanese English (Outgoing language A).

* Interpreters can do a switch operation to monitor the audio of language group 1 (key language) 25 Out of the three languages, the language of Audio Group 1 is used as the key language (in this case it is English), and relay interpretation is possible. (diagram below) When interpreting from French to Japanese, for example, Interpreter C first interprets French English. Interpreter B switches the monitor channel to the key language 1, listens to the English interpretation from interpreter C, and then interprets English Japanese. Other than that, the basic operations are the same as those for 2 languages. Audio Group 1 English

(3 holes) on the bottom side of the 50DU/INT (screw: M3, P=0.5, within 6 mm from the bottom side to the tip of the screw). NOTICE Do not plug in the supplied AC power cord until all other 95 30 connections have been completed. Insert the plugs all the way in. Loose connections may cause malfunctions or noise. Check the plug orientations. Refer also to the instruction manuals supplied with the external devices. Although connecting the 50CUs, 50DUs, and INTs are described here, because basic IU connections are the same as those for 50DUs, refer to how to connect the DUs when connecting IUs. However, refer to the table Relationship of the LAN cable length, number of units connected and number of EXTs required (page 30, 34) regarding the number of IUs to connect. 7 8

Connecting 50DU/INT to 50CU 1 Place the 50CUs and 50DU/INTs. NOTICE Install the units on a flat surface. Dropping a unit may cause damage to the unit and/or personal injury. When installing the 50CU in a rack, read the precautions in advance (page 5). 2 Connect the 50DU/INTs to the DU CHAIN A/B terminals. 1 1 5 4 Speaker Amplifier NOTICE Use straight cables. (Shielded cables with conductor size of 24AWG or higher in diameter) Using flat-type cables or unshielded cables may cause noise and affect other devices. Be sure to establish a ground connection. 27 Ethernet cable Remove the 50DU/INT bottom cover to connect the Ethernet cables. To remove the bottom cover, pinch together the latches on both sides. On the 50DU/INT, the 50DU/50CU connection terminals are not differentiated, so you can connect to either the left or right terminal. Ring connection:

Connect the 50DU/INTs to each of the DU CHAIN A/B terminals and then connect together the last 50DU/INTs together to form a ring. Even if a connection failure occurs somewhere in the ring, since the connection is recognized as 2 daisy chains using the DU CHAIN A/B terminals, the influence of the failure can be minimized and you can continue operating.

Connecting the 50DU/INTs together To ATUC-50CU One more ring connection can be made by configuring these terminals as the DU CHAIN C/D terminals. Ethernet cable Ethernet cable 1 Connect the 50DU/INTs according to the installation environment and operation method. Daisy-chain connection:

Connect the 50DU/INTs in a series to the DU CHAIN A/B (C/

D) terminals. Compared to a ring connection, a daisy-chain connection enables the 50DU/INTs to be placed even farther from the 50CU. Even if a connection failure occurs, since the connection is recognized as 2 daisy chains using the DU CHAIN A/B terminals, you can carry on conference control. Combining different connection types is also possible, such as a ring connection using the DU CHAIN A/B terminals and daisy-chain connections using the DU CHAIN C/D terminals. If a connection failure occurs here, all the connections to the last DU/INT are disabled. Final 50DU/INT Final 50DU/INT Daisy-chain connection Ring connection 2 Expand the system with EXT. By adding EXT to the system, you can increase the number of 50DU/INT connections and extend the distance of the total extension length of the connecting cable (LAN cable). For instance, you can connect a total of 100 50DUs/INTs, 50 units on either terminal, by connecting an EXT near the B terminal when using a daisy-chain connection on both the DU CHAIN A and B terminals. 28 Maximum number of connections for each terminal/each 50CU in Standalone mode Maximum number of terminal connections in a DU CHAIN A 50 B 50 C 50 D 50 50 50 Total 100*

* The maximum number of units that can be connected is up to 100 units to each terminal on the DU CHAIN by using the EXT.

* IUs consume more power than 50DUs, so the number of units shown in the table cannot be connected. If you connect that many, it may damage the 50CUs or the EXTs. Refer to the table Relationship of the LAN cable length, number of units connected and number of EXTs required (page 30, 34) regarding the number of IUs that can be connected.

It may damage the 50CU or the EXTs. Depending on the CU settings, you can also connect the DUs/IUs to the CU LINK terminals by configuring them as DU CHAIN C/D terminals. However, if the number of the DUs connected to the DU CHAIN A/B terminals has not reached the maximum, be sure to connect them to the DU CHAIN A/B terminals. The above table and notes are the same for the INT and 50DU. However, a maximum number of 6 INTs can be connected to one system. The combinations shown above are representative examples. For other combinations, please inquire with our sales representative. The position in which to connect the EXTs should have the same number of 50DUs (A, B, and C in the following diagram) between EXT-EXT as there are between 50CU-EXT connected to the 50CU 1 port. For example, do the connections as follows for an L1 = 10 m, L2 = 1.5 m, and L3 = 10 m, with 50 units connected to a 1 port daisy-chain connection.

Loose connections may cause malfunctions or noise. Check the plug orientations. Refer also to the instruction manuals supplied with the external devices. 1 Install the IRCU and IRA. NOTICE Install the IRCU on a flat surface. Dropping a unit may cause damage to the unit and/or personal injury. When installing the IRCU in a rack, read the precautions in advance ( page 5). Refer to the Instruction Manual - Installation Edition to install the IRA. Entire system connection diagram 2 Use BNC cable to connect the IRCU and IRA. 1 2 4

Connecting the microphone ATUC-M to the IRDU 1 Connect the ATUC-M to the microphone jack on the IRDU. 57 When removing the rechargeable batteries:

While pressing the rechargeable battery/rechargeable battery cover release button, slide the rechargeable battery in the direction of the arrow. Press to remove rechargeable batteries NOTICE Insert it until you hear a click. Do not lift the IRDU by holding the ATUC-M. Be sure to hold the main body of the IRDU when holding it. Slowly bend or extend the flexible part of the ATUC-M. Do not apply excessive force to the ATUC-M when bending it. When disconnecting the ATUC-M from the IRDU, securely hold the connector while pressing down the microphone release button and then remove the ATUC-M. Before connecting/disconnecting the ATUC-M, be sure to turn off the power. If you do not turn off the power, a malfunction may occur.

Starting the IRDU 1 Insert the rechargeable batteries into the IRDU. Insert the rechargeable batteries into the bottom of the IRDU. Then, just slide the rechargeable batteries in the direction of the arrow to secure them. There is a click sound so you can confirm that the batteries are securely mounted. NOTICE You can install two rechargeable batteries, but one is enough to operate. If you install both rechargeable batteries, power is consumed from the first one. The IRDUs do not have a recharging function. To recharge them, use Audio Technica's specialized charger

(ATCS-B60).

Setting Device ID for IRDU You need to set individual IDs for each IRDU before you can use them. They cannot be used correctly if you do not set the ID numbers. There are two setting methods. Auto Setting automatically assigns an ID in the order the IRDUs are connected to the IRCU. With Manual Setting, you set the ID on the IRDU itself. This setting is done only one time and the ID numbers are recorded in memory. You can use 200 ID numbers, from 001 to 200, but no other numbers can be set. (All the numbers are set to 001 at the factory.) Auto setting:

While pressing the BACK button, turn on the IRCU to enter the device ID setting mode. When audio-technica ATUC-IR appears in the OLED, release the BACK button. Wait until the OLED display changes to ATUC-IRDU Device ID Auto Assign Mode..., then, while pressing the

</> monitor channel selection buttons, turn on each IRDU one at a time in order. The IDs are automatically assigned in the order in which you turn the IRDUs on. After you have confirmed the ID, press the right multifunction button to set the ID. You can also set any ID you want by doing the same operation as Manual Setting. After setting all the IDs, restart the IRCU. If you are using an AC adapter (sold separately):

Attach the rechargeable battery covers to the IRDU. NOTICE Extend the cord of the AC adapter through the hole for the cord. Do not pinch the cord when you attach the rechargeable battery covers. Doing so may cause the cord to break. 58 NOTICE For any DUs that were not assigned an ID, such as due to poor infrared transmissions, turn off their power, and then, while pressing on the "<"/">" monitor channel selection buttons, turn on the power and perform "Auto Setting" or "Manual Setting" to specify the ID. Manual settings:

While pressing the </> monitor channel selection buttons, press the power switch. Look at the display to input the ID number you want.

<Example: To set ID number 152>

1 While pressing the </> monitor channel selection buttons, press the power switch. 2 Press the </> buttons so the 2 appears as the first digit. 3 Press the left multifunction button to set the second digit. 4 Press the </> buttons so the 5 appears as the second digit. 5 Press the left multifunction button to set the third digit. 6 Press the </> buttons so the 1 appears as the third digit. 7 Press the right multifunction button to apply the setting.

(After step 7, you can use the system in regular modes.) Additional procedures closely follow the procedures for the ATUC-

50 system. Refer to Connecting an amplifier (page 38) in Wired System Connections and Configuration. 59 ATUC-50/IR Hybrid System The ATUC-50 wired conference system and the ATUC-IR infrared conference systems can be combined, and operated as a hybrid conference system.
