Control host introduction ODS-8500M:

     This system is the wireless conference system adopted infrared ray by transfer’s medium of sound. It has many spoken mode. Set attendance, voting, elections, evaluation, auto-tracking camera functions into one; install convenient and operate easily, with full function and high keeping secrecy. It is the advanced product in the field of conference system at present.

Function and specialty:

1. With safety and high secrecy, it prevents wiretapping and defends electromagnetism from mobile phone.

2. Adopt the mode of frequency modulation to come true transfer of sound signal with wireless. It is with high fidelity, high SNR (S/N ratio) and so on. Using the MIC head with restraining howl and high sensitivity, it makes the sound be more perfect.

3. It has seven spoken mode, including FIFO mode (1/2/3), limit mode (1/2/3), C. mode choosing and so on. Set attendance, voting, elections, evaluation, auto-tracking camera functions into one, it is Up to 128 to meet the various requirements of the conference place.

4. install convenient and operate easily; you can move them free in the covering with range of signal.

5. Adopt the power supply with Large-capacity lithium batteries; the Standby time is up to 25 hours; it has two ways of charging up with direct charging and charging case; with an intelligent charge management circuitry, it can protect the battery effectively to extend battery life and ensure safety

6. Using a large-screen LCD design, steady and generous; the units are with plastic material; the appearance is novelty and delicacy, feeling best.
