Master of Meeting Infrared system
Digital Infrared wireless conference system integrates the advantages of digitalization, wireless and Infrared transmission technology, perfect sound quality, easy to install and move, easy to use and maintenance, not affected by buildings, is an excellent solution for wireless conference system.

• Infrared transmission technology, high security and confidentiality, anti-eavesdropping, anti-mobile phone electromagnetic interference; Ensure the confidentiality of meetings

• World advanced digital Infrared audio transmission and control technology, not limited by radio frequency use

• Using 4-8 MHz transmission frequency, without interference from high frequency driving light source, in line with international standards

• Using full-duplex Infrared to achieve sound signal transmission, high sound fidelity, high SNR, no sound delay;

• New anti-noise single point high sensitivity pick up head, sound more perfect;

• Both the voice signal channel and the control signal channel adopt wireless mode, without tedious laying of cables, simple connection can be used by turning on the power supply, and can be moved at will within the signal coverage range;

• Alternate 1-2-3, limit 1-2-3, 7 speech modes dedicated to the chairman, and can be equipped with external video tracking function, applicable to the meeting room in 127 non-attendance units;

• The battery uses super large capacity lithium battery power supply, can speak for 8 hours and 25 hours standby time there are two charging modes: direct charging and using the charging box;

• Large-screen LCD display, hierarchical menu design, with power display, underpower alarm, online number of people, signal indication, etc.

• Any number of digital Infrared wireless conference systems can be installed in one building
