Meeting Master Infrared OBT-2288R

Meeting Master  Infrared system of OBT-2288R
 
I. System description
The system is a set of wireless conference system working in UHF frequency band, fully digital control, with a variety of speech modes, and can be connected to the video host to realize the video tracking function. The power supply of the unit in attendance can be ordinary battery or rechargeable lithium battery, which is convenient and environmental friendly. The system is simple to operate, no engineering installation, economic and practical, is the first choice for conference engineering.

II.Functions and Features
Using FM frequency modulation to achieve sound signal transmission, high fidelity, high signal to noise ratio, no sound delay. The use of a unique new anti-noise single point high sensitivity capacitor microphone, so that the sound of the meeting is almost perfect.

The audio channel and the control channel are transmitted in wireless way, without laying cable, and the signal can be moved freely in the park, so that the venue layout is convenient and flexible.

Independently developed data communication algorithm for conference applications, so that the response speed of the system is not affected by the number of present units within the signal range. Users can flexibly add or subtract participant units. By default, the number of attendance units in the system is ≦255 (including one chairman).

With 1-2-3-4, 1-2-3-4, limited 1-2-3-4, the chairman's proprietary conference speech mode, the main control machine can be connected to the external video host, to achieve the conference participant unit's video tracking function.

Ultra-low power consumption, more than 8 hours of continuous speaking time and more than 20 hours of standby time; No. 5 ordinary battery or original lithium battery can be used. Supporting charging box with intelligent charging management circuit, effectively protect the battery, prolong the battery life and ensure safety.

Large LCD display. Hierarchical menu design makes operation simple and convenient. And there are many such as power display and undervoltage warning, frequency channel and signal indication and other functions.

The main control work adopts all metal structure design, solemn and generous; The seating unit is made of engineering plastic material and novel appearance design, built-in antenna, beautiful and decent.
