Trasmisor IR
  • Trasmisor IR

Digital Infrared Transmitter

The transmitter is the central element in the language distribution system. It accepts analogue or digital input, modulates these signals onto carrier waves and transmits these carrier waves to radiators located in the room. Compliant to IEC 61603-7 and IEC 60914. Compatible with any other IR simultaneous interpretation system compliant to IEC 61603-7. DQPSK digital modulation/demodulation technology. Transmitting in 2~8 MHz frequency band eliminates disturbance from high frequency lighting systems. Capable of distributing a maximum of 16 audio channels. Auxiliary mode for distribution of music to all channels during a break. Slave mode for distribution of signals from another transmitter allows multiple rooms to be used.

Controls and Indicators

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



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