The transmitter is the central device 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 and the latest national standard GB 50524-2010
  • 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 4, 8 or 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
