MC880 wireless digital conferencing system host
The MC880 wireless digital conferencing system is a set of digital wireless conferencing system operating at UHF high frequency band.
The system is operated under full digital mode and various speaking modes, and can be connected to MC880B video host to achieve video tracking function.
The FM is used to transmit sound signal, Hi-Fi, high SNR and without sound delay.
The unique new condenser microphone core with characteristics of whistling-free, unidirectional performance and high-sensitivity makes sound of the conference almost perfect.
The audio channel and control signal are transmitted wirelessly without wiring and the units are randomly located within signal coverage, so layout of the conference site is flexible.
The data communication algorithm independently developed for conferencing enables system response rate not subject to number of delegate units within signal coverage. Users add or remove delegate units flexibly.
System delegate unit capacity≦1255 pcs (including 1 chairman unit)
Various conferencing speaking modes of alternative 1-2-3-4, limit 1-2-3-4 and exclusive chairman are optional and the main controller is externally connected with K880B video host to deliver video tracking function for delegate units at conference site.
Ultra-low power consumption provides the delegate units with more than 8 hours’ continuous speaking and more than 20 hours’ standby.
The USB charger provided by the manufacturer carries smart charging management circuit to protect battery effectively, extend battery life and ensure safety.
Large-screen LCD display
The hierarchical menu design enables operation simple and convenient, such as electric capacity display and under-voltage alert, frequency channel and signal display.
The master control unit is of full-metallic structure design, grand and decent.
The delegate unit is treated with engineering brand-new flocking process, novel shape design, built-in antenna, nice-looking and appropriate.
Each unit is powered by chargeable lithium battery and completed with mini USB charger, convenient and environmental protection.
The system is operated simply, installed without engineering cabling, economical and practical, and is a preferred choice for large and small-sized conference projects.
