Overview of the Interpretation Unit (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

Audio Group 2
Japanese
Audio Group 3
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. W hen the system is started, the interpretation pattern is “Japanese
English (Outgoing language A)”.

- 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.

Wired System Connections and Configuration
Connecting devices
NOTICE · Do not plug in the supplied AC power cord until all other 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 29,
33) regarding the number of IUs to connect.
Entire system connection diagram (1) Refer also to the entire system
connection diagram (2) ( page
38)
When securing a 50DU/INT to a desk or table, use the screw holes (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 · Use straight cables. (Shielded cables with conductor size of 24AWG or
higher in diameter are recommended.)
· Using flat-type cables or unshielded cables may cause noise and affect other
devices.
· Be sure to establish a ground connection.

e
- 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.
2 Connecting the 50DU/INTs together
To ATUC-50CU
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.
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.

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.

- 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 29, 33) regarding
the number of IUs that can be connected.

The values in the tables above are calculated based on the following
assumptions. · The number of 50DUs that can be connected is based on the
assumption that the ATUC-M is used. · The number of IUs that can be connected
is based on the assumption that ATUC-M, TALK LED, FLOOR LED, 8- speaker units,
32-
impedance headphones, and GPO terminals with LED x 4 (7 mA each) are being
used. · Given that Cat5e or higher cables are used. (Shielded cables with
conductor size of 24AWG or higher in diameter are recommended.) · 1-port
daisy-chain connection/1 ring connection: Given that one of the DU CHAIN A/B
terminals is connected in a 50DU/IU daisy chain
or that the A-B terminal is connected in a ring. · 2-port daisy-chain
connection: Given that the same number of 50DUs/IUs are daisy-chained to the
DU CHAIN A/B terminals. · 4-port daisy-chain connection: Given that the same
number of 50DUs/IUs are daisy-chained to both the DU CHAIN A/B terminals and
the same number of DUs/IUs are daisy-chained to the DU CHAIN C/D terminals. ·
2-ring connections: Given that one ring connection is used for the DU CHAIN
A-B terminals and for the DU CHAIN C-D terminals.

NOTICE · When connecting 50DUs/IUs, never exceed the number of connectable
50DUs/IUs and the connectable length. 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.

CU Link connection: Up to 3 50CUs can be cascaded (cascade 50CUs using the CU
LINK A/B terminals as shown below). Set one of the 50CUs as the primary unit.
Since up to 100 50DU/INTs can be connected to each 50CU, if you use 3 CUs, up
to 300 50DU/INTs can be connected in total.
Follow the procedure below to cascade CUs. Connect the CU LINK A terminal on
the 1st extension 50CU to the CU LINK B terminal on the primary 50CU. When
cascading 2 extension 50CUs, connect the CU LINK A terminal on the 2nd
extension 50CU to the CU LINK B terminal on the 1st extension 50CU. Primary
50CU
Terminal A is not used.
- You can either daisy-chain ( page 27) or ring ( page
- 50DU/INTs to each 50CU.
NOTICE · When using only one 50CU without a CU Link connection, be sure to set [CU Link Settings] to [Primary]. If [CU Link Setting] is set to [Extension Pass Through] or [Extension Last Unit], we cannot assure operations.
· Up to 6 INTs can be connected to the primary 50CU. They cannot be connected to extension 50CUs.
3 Attach the bottom cover to the 50DU/INT.
After connecting the Ethernet cables to the 50DUs/INTs, attach the bottom cover to each 50DU/INT. · The Ethernet cable is fixed securely between the 50DU/INT
and the bottom cover. This helps reduce the weight of the 50DU/INT which bears on the Ethernet cables. · To lead the cable out to the rear side, use the through hole . To lead the cable out to the bottom side, use the through holes .

ATUC-50DU/INT NOTICE · Insert the ATUC-M connector in until you hear a
clicking sound. · Do not attempt to lift up the 50DU/INT by grabbing
onto the ATUC-M. Be sure to hold the main body of the 50DU/INT when lifting it
up. · Slowly bend or extend the flexible part of the ATUC-M. Do not apply
excessive force to the ATUC-M when bending it. · W hen disconnecting the
ATUC-M from the 50DU/INT, securely hold the connector while pressing down the
microphone release lever 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, malfunction may occur.
NOTICE · When connecting external devices to IN/OUT terminals, do so after
cutting the phantom power supply of the external devices. If you leave the
phantom power supply on, it may cause unexpected malfunctions.
· When connecting external devices, refer also to the instruction manuals
supplied with them.
5 Turning on the 50CU and testing 50DU operations
After checking that all the connections from steps 1 to 4 have been done
properly, follow the procedure below to turn on the power of the 50CU.
1 Check that all the PA devices such as an amplifier
and mixer are off.
2 Connect the supplied AC power cord to the 50CU.
NOTICE · Be sure to use the supplied AC power cord. Using an AC power cord
other than the supplied one may cause problems such as damage to the 50CU,
which can be very dangerous.
· Be sure to connect the AC power cord into a properly grounded wall outlet.
Improper grounding can cause electrical shock.
· Be sure that the 50CU is securely grounded to a single ground point.

4 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.
57
e
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 “4 Connecting an amplifier” (page 37) in
” Wired System Connections and Configuration”.

About CU link connections: IRCU/IRCUDAN as primary and up to 2 50CUs as
extension can be cascaded (use the CU LINK A/B terminals for connections as
shown below). Since up to 100 50DU/INTs can be connected to each CU, if you
use 3 CUs, up to 300 50DU/INTs can be connected in total.
Follow the procedure below to cascade CUs. Connect the CU LINK A terminal on
the 1st extension CU to the CU LINK B terminal on the primary CU. When
cascading 2 extension CUs, connect the CU LINK A terminal on the 2nd extension
CU to the CU LINK B terminal on the 1st extension CU.
