Simultaneous Interpretation Equipment Conference System Digital Infrared Receivers Multi Languages Translation
- Compliant with IEC 61603-7 and IEC 60914
- Compatible with any other IR simultaneous interpretation system compliant with IEC 61603-7
- Digital infrared processor with DQPSK digital modulation/demodulation technology
- Transmitting in a 2~8 MHz frequency band eliminates disturbance from high-frequency lighting systems
- Channel selection via up/down button, at most 4,8,16 or 32 channels available
- LCD with channel number, language name, battery, and signal status indication
- The number of available channels is always the same as the number of channels in use by the system, eliminating the need to scroll through unused channels
- Adjustable volume
- Unique 270º super wide reception angle, ensuring perfect sound quality even when casually placed
- The audio signal is automatically muted when the signal is too low, ensuring that the user receives only high-quality audio.
- Ergonomically compact and elegant design
- Lightweight and handy receiver in conjunction with single earphones or headphones for easy and comfortable use
