H-6700M Digital IR Wireless Simultaneous Interpretation System Transmitter Unit
This digital IR language distribution system is designed for wireless distribution of audio signals using infrared radiation. It can be used in a simultaneous interpretation system for international conferences where multiple languages will be spoken. In order to enable all participants to be able to understand the discussion, interpreters simultaneously translate the speaker’s language as required. These interpretations are distributed trough the conference venue, and delegates select the language of their choice, and listen to it using headphones. The system can also be used for music distribution.
◆ Full digital wireless transmission technology, system conforms to IEC61603, part 7
◆ 2-8MHz frequency band eliminates disturbance from all types of lighgting system
◆ The system main transmitter provides multi-channel (4/8/12/16) for option (3/7/11/15 foreign language + 1 original/floor language)
◆ Infrared radiator, reciver and interpretor console support 4/8/12/16/32 channels transmission
◆ Powerful compression techniques enable efficient, low-loss transmission
◆ High security, prebent external interference
◆ Elegant configuration in accordance to ergonomics
