Conference main controller technical features:

1. Work with 20M super category extension cable, maximum 60 microphone units can be worked with one main controller .
2. Maximum 128 microphone units can be worked together by extension power supply.
3. Maximum 1200 microphone units can be worked together by additional extension main controller.
4. Adopt4 line RJ45 port / super 6 category cable to connect with microphone unit

5  Hand in hands connection, support hot-swap, easy to installation and maintenance.

6  Adopt LOOP power supply connection, works more stable and reliable.

7.  Design with 5 inch capacitive touch screen, easy to read or adjusting the system

data.

8.  With audio input port, to input background music or any others audio signal.

9.  With2 line primitive output, to connect with amplifier or record equipment.

10. With 2 line XLR audio out put, to connect with amplifier directly for small conference.

The conference controller is equivalent to a central controller and a audio processor.

1. Speaker number limited function: to set maximum speaker number in same time ( from1 to 6), the chairman unit is unlimited.
2. Support FIFO(First  In First Out), NORMAL, FRQQ(Free QQ), APPLY, VOICE multiple speaking mode.
3. Adopt high-performance DSP processor,to process 32-segment audio equalization, noise reduction,to make the sound clear and thorough .and effectively suppress screaming.
4. Support check-in, voting, and date management.
5. Support automatic camera tracking.
6.  WithUSB recordingfunction, connect with USB to record the conference audio signal.
7. .to haveteleconference with telephone coupler.
8.  2U metal frame case, easy to install into 19 inch rack case.

Microphone unit technical features:

 1. Adopt 6 category cable , hand-in-hand connection, design with 2 RJ45 portsand a jacket to prevent loosening.

1. New design big dimension condenser, with Cardioid Directional Directivity,the Sound is clear and nature.
2. Design with anti-interference gooseneck tube,plug-in function. Easy to transport and maintenance.
3. Design with 128 * 64 OLED screen, easy and clearly to display all operations such as voting mode, unit parameters& speech level, etc.
