Fully Digital Wireless Transmission Digital IR Transmitter unit
SP-IRS700 Digital IR Transmitter unit Describtion:
The digital IR language distribution system is a system for wireless distribution of audio signals via infrared radiation. It can be used in a simultaneous interpretation system for international conferences where multiple languages are used. To enable all participants to understand the discussion, interpreters simultaneously translate the speaker's language as required. These interpretations are distributed throughout the conference venue, and delegates select the language of their choice and listen to it through headphones. The system can also be used for music distribution.
SP-IRS700 Digital IR Transmitter unit Features:
1. Fully digital wireless transmission technology. System conforms to LEC61603,part 7.
2. 2-8MHz frequency band eliminates disturbance from all types of lighting systems.
3. The system provides multi-channel 4/8/12/16 for option.
4. Powerful compression techniques enable efficient, low-loss transmission.
5. High security, prevent external interference.
6. Elegant configuration in accordance to ergonomics.
