Product Description

Digital IR Language Distribution System Digital Infrared Transmitter with Four Configuration Buttons

Features
 

1. Compliant to IEC 61603-7 and IEC 60914 and the latest national standard GB 50524-2010
2. Compatible with any other IR simultaneous interpretation system compliant to IEC 61603-7
3. DQPSK digital modulation/demodulation technology
4. Transmitting in 2~8 MHz frequency band eliminates disturbance from high frequency lighting systems
5. Capable of distributing of 4,8 or 16 audio channels
6. Auxiliary mode for distribution of music to all channels during a break
7. Slave mode for distribution of signals from another transmitter allows multiple rooms to be used
8. Radiator and system status indication via display and indicators
9. Each transmitter can be assigned a unique name by the installer for easy identification in a multi-transmitter system
10. Automatic distribution of emergency messages to all channels
11. Automatic synchronization to the number of channels in use by the CLEACON system
12. Each audio channel can be assigned a language name for easy identification
13. The sensitivity of each input is adjustable, the audio level can be fine-tuned, and the audio input level indication is supported
14. Flexible configuration of channels and channel quality modes: Mono, standard quality, maximum 16 channels Mono, perfect quality, maximum 8 channels Stereo, standard quality, maximum 8 channels Stereo, perfect quality, maximum 4 channel
15. With 16 interpretation output channels for recording
16. Universal power facility allows worldwide use
17. Conference hall privacy; the congress venue itself acts as a barrier to infrared signals escaping and being overheard, as infrared is unable to pass through opaque objects such as walls
18. Suitable for various kinds (small/medium/large international) of conference halls and outdoor venues
19. Can directly connect with interpreter desk VIS-INT64
20. With 16 channel analogue audio input and 16 channels analogue audio output.
21. 2 transmitters can work as master and slaver mode for 32 channel language distribution
22. Connecting to Dante network by optional Dante port

 

Control and Indicators

1. Graphic LCD with back-lighting displays status and menu of the system configuration, supporting multi language menu
2. Four buttons for configuration
3. Channel active indicators

Interconnections

1. 2 female XLR connectors for external audio inputs to connect auxiliary balanced audio signals such as music, floor language or emergency audio signal
2. 16 audio signal output connectors (phoenix sockets) for output multi-channel audio
3. 16 audio signal input connectors (phoenix sockets) to connect external unbalanced audio input signals
4. 6 BNC connectors for output HF signal to radiator. To each connector, up to 30 radiators can be connected
5. 1 BNC connector for receiving HF signal from another transmitter
6. Audio-Link Port for connecting to Interpreter Unit or VIS-DCP2000 or VIS-DCP1000 conference controller
7. DANTE port for connecting to Dante network for the digital audio(Optional VIS-DANTE module)
8. Ethernet and RS232 ports for connection to computer
9. Emergency signal interface: when the public emergency system is active, alarm signal can be fed to all channels automatically
10. Power supply socket
