product description:
Fully digital design, greatly improved sound quality and anti-interference ability
Comply with international standards IEC 61603-7 and IEC 60914
Comply with national standard GB 50524-2010
Compatible with other infrared simultaneous interpretation systems that comply with IEC 61603-7 standards (can be used cross-wise)
Support 4, 8, 12, and 16 audio channels
Adopt 2~8MHz carrier frequency band, complying with the frequency band specified by international standards
The widening design is adopted in both vertical and horizontal directions, and the signal radiation angle is wider.
Adopting a filter design, it effectively resists stray light interference and can work normally in complex environments such as sunlight and neon lights.
The hand-in-hand signal radiation enhancement coverage mode can easily expand the signal coverage and can also be configured into a multi-room mode.
It has cable transmission delay compensation function to ensure correct superimposed transmission of signals.
Infrared rays cannot penetrate walls or ceilings, ensuring the privacy of the meeting
Humanized human-machine interface design, simple and easy to use, no need for in-depth training.
Exquisite appearance design, showing elegance
