Wireless Conference Video Tracking System Base Unit [M6800]

Product Overview: Base Unit Functions

This system is a wireless conference system operating in the UHF band, featuring full digital control, multiple speaking modes, and connectivity to video hosts for camera tracking functionality.

Delegate units are powered by built-in, high-capacity rechargeable lithium batteries, offering extended standby time for convenience and eco-friendliness. The system is easy to operate, requires no complex installation, and is cost-effective, making it an ideal choice for conference applications.

Key Features:

• Utilizes FM modulation for audio signal transmission, ensuring high-fidelity sound, excellent signal-to-noise ratio, and zero audio delay.

• Equipped with a new anti-feedback, uni-directional, high-sensitivity condenser microphone capsule for superior conference audio quality.

• Both audio and control signals are transmitted wirelessly, eliminating the need for cabling. Units can be freely moved within the signal coverage area, allowing for flexible and convenient venue layout.

• Independently developed data communication protocol for conference applications ensures system response speed is unaffected by the number of delegate units within range. Users can flexibly add or remove delegate units (default system capacity: ≤255 units, including 1 chairperson unit).

• Supports multiple speaking modes: First-in-Last-out (1-2-3-4), Limited (1-2-3-4), and Chairman Priority. The base unit can connect to an external video matrix for delegate unit camera tracking.

• Ultra-low power consumption: Delegate units offer >8 hours of continuous speaking time and >20 hours of standby time. Compatible with standard AA batteries or the supplied original lithium battery.

• The matching charging case features intelligent charging management circuitry to effectively protect batteries, extend their lifespan, and ensure safety.

• Large LCD screen with a hierarchical menu design for simple and convenient operation. Includes functions such as battery level display, low-voltage warning, frequency/channel, and signal indicators.

• The base unit boasts a full-metal structural design for a dignified appearance. Delegate units use engineering plastic with a novel design, featuring a built-in antenna for a sleek and appropriate aesthetic.
