K-2800 Multifunctional Wired and Wireless Conference System

In stock


FM frequency modulation is used to realize sound signal transmission, with high fidelity, high signal-to-noise ratio and no sound delay. Using a unique new anti-howling single-point high-sensitivity condenser microphone core, making the meeting sound almost perfect.

Both the audio channel and the control channel are transmitted wirelessly, without laying cables, and the signal coverage area can be moved arbitrarily, making the layout of the venue convenient and flexible.

Independently developed data communication algorithm for conference applications, so that within the signal range, the system response speed is not affected by the number of attending units. Users can flexibly increase or decrease attendance units. The factory default system attending unit capacity is ≦255 (including 1 chairperson).

With alternate 1-2-3-4, restricted 1-2-3-4, and a variety of conference speech modes exclusive to the chairman, the main control machine can be connected to the video host to realize the video tracking function of the conference room attending unit.

Ultra-low power consumption, the attending unit has more than 8 hours of continuous speaking time and more than 20 hours of standby time; both ordinary batteries or the original lithium batteries of the manufacturer can be used. The matching charging box has an intelligent charging management circuit, which can effectively protect the battery, prolong the battery life and ensure safety.

Large-screen LCD display. The hierarchical menu design makes the operation simple and convenient. And there are many functions such as power display and undervoltage warning, frequency channel and signal indication.

The main controller adopts an all-metal structure design, which is solemn and elegant; the attending unit adopts engineering plastic material with a novel appearance design, built-in antenna, and beautiful and decent.
