Product Description

VOSS AUDIO ONLINE CONFERENCE MIC SYSTEM

Online Conference Host MK-800A
■Adopt digital-analog to realize sound signal transmission, high fidelity, high signal-to-noise ratio, and no sound delay. Using a unique new anti-whistling unidirectional high-sensitivity condenser microphone core, the conference sound is almost perfect
■ The independently developed data communication algorithm is applied to the conference, so that within the signal range, the system response speed is not affected by the number of non-voting units. Users can flexibly increase or decrease the attendance unit.
■ It has the functions of rotating 1-2-3-4, limiting 1-2-3-4-, and the chairman's exclusive conference speech mode.
■ Ultra-low power consumption, the unit has a continuous speaking time of more than 10 hours and a standby time of more than 20 hours; AA batteries or the original nickel-metal hydride batteries can be used. The matching smart charger can effectively protect the battery, prolong the battery life and ensure safety.
■ Large-screen 2.4-inch TFT color 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 panel has a 2.4-inch TFT color display to display the conference mode, and the working menu.
■Built-in recording function, the host shuts down for 5 minutes, and the unit shuts down automatically to avoid wasting battery power and causing unnecessary trouble.
■It can be operated independently or with an external computer combined with software and other external devices synchronously and linked to achieve computer management functions (mode or operation: free speech, first-in first-out, etc.

Online Conference Mic MK-800C/MK800D
