About This Conference System
Features
Features of ATUC‑50/ATUC‑IR system
• Audio processing by the feedback processor and the like enables
clear-sounding conversations
• Up to 6 interpretation units (ATUC-50INT) can be connected.
• The maximum number of discussion units (ATUC-50DU),
integration units (ATUC-50IU), and interpretation units (ATUC-
50INT) that can be connected on the IRCU is a total of 500 units
(IRCU x 1 + 2 CU link units, 200 IRDU units, and 300 50DU
units) and on the 50CU is a total of 300 units (for 3 CU link
units).
• Either daisy-chain or ring connection can be made with Cat5e or
higher cables (shielded cables with conductor size of 24AWG or
higher in diameter are recommended).
• 3 selectable conference modes: Free Talk Mode, Request Talk
Mode, and Full Remote Mode
• 2-language interpretation, 3-language interpretation, and
3-language relay interpretation are supported (ATUC-50INT)
• The recording function enables you to record audio onto a USB
device (mass storage device)
• Controllable using Web Remote and an external control device
• Design with future expansion considered
• Layout of hybrid infrared conference system can be easily changed
and operations are flexible.
About Audio‑Technica LINK
The system uses Audio-Technica’s proprietary LINK format for
power supply and signal transmission between the control units and
discussion units, etc.
Audio-Technica LINK is compatible with the Ethernet standards
and allows a simple installation using universal Cat5e or higher
cable connections. (A shielded cable with conductor size of 24AWG
or higher in diameter is recommended.) Transmission of high-speed
signals with low-latency allows stable control and uncompressed
audio signal transmission.
Features of ATUC‑50CU
• Power supply and control is possible for a maximum of 100
discussion units (ATUC-50DU) (depending on the cable lengths
ATLK-EXT165 may be required)
• Up to 300 discussion units (ATUC-50DU) can be connected by
cascade-connection
• 4 configurable balanced matrix output plus 1 unbalanced output
that outputs the same audio as Output 1
• 2 Mic/Line inputs, 2 monaural AUX inputs, and 2 return inputs
• 2 return channels are available for both bilingual simultaneous
interpretation and the language of the floor holder
• Conference mode: Free Talk, Request Talk, and Full Remote
• Priority mode: First-press priority and later-press (FIFO, LIFO)
priority
• Talk mode: Manual mode, Voice activation mode
• Web Remote enables you to easily change settings and control
attendees' right to talk during conference
• Up to 4 channels (WAV: up to 4 channels, MP3: up to 2 channels)
can be recorded on a USB device (mass storage device)
• Audio processing by the feedback suppressor and the like enables
the control unit to deliver high-quality sound
• Design with future expansion and renewal considered
Features of ATUC‑50DU/INT
• An LED ring enables power supply via 3-pin balanced connector
while offering both high sound quality and user flexibility
• Standard 3-pin microphones can be connected
• A microphone pre-amplifier using discrete transistors reduces
noise; moreover individual gain is adjustable
• A high-quality and high-resolution speaker
• Designed for the high sound qualities of 24 bit/48 kHz
• Equipped with multiple independent indicators (microphone ring
LED, (talk) button, multicolored LEDs on rear side of
discussion unit (ATUC-50DU))
• High-visibility indicators associated with the headphone volume
adjustment buttons and monitor channel selection buttons
• Optional removable bottom weight for improved stability
• 2 RJ-45 terminals for connecting discussion units (ATUC-50DU);
1 expansion RJ-11 terminal for future expansions
• 1 headphone output jack with a monitoring channel switch
function
Features of the ATUC‑IRCU/IRCUDAN
• Updated model has expanded FPGA, and the basic functions are
the same as the 50CU
• Supports operation on wired conference systems, infrared
conference systems, and hybrid conference systems
• One system can control up to 300 discussion units (100 50DU
units and 200 IRDU units, plus ATLK-EXT165 may be required
depending on the number of connected units, cable lengths, and
number of antennas)
• Up to 500 conference microphones can be connected in cascade
connections (300 50DU units and 200 IRDU units)
• Dante equipped models are also available
