Digital Conference System DC-710M

Product Description

*Full digital circuit development & design, intelligent identification of representative and chairman from the mainframe without IP address allocation. Mic unit can be optionally added. 

*Circuit design of anti-jamming circuit can eliminate interference from all mobile phone signals;

*Clear sound, Hi-Fi, little noise jamming, high security and easy installation

*Electronic volume inside the system unit can control every single regulatory function of output and input.

*Dual safety device are provided, including internal alternating current and direct current channel, automatically powering off when overflowing. 

*The mainframe can be connected to 500 units in four ways with the inclusion of 1000 units when extending.

*The control of conference function can be realized through functional key on display screen measuring 2.8 cun.

*With regarding to the numbers of chairman, 12 units is at the utmost, and the numbers of spokesman can be set up arbitrarily ranging from 1 to 12.

*Multiple conference patterns: Modes of open discussion, quantitative limitation, FIFO, LIFO, exclusive use for the chairman, satisfy the requirements of various conferences. 

*Two types of time limitations include speaking time and conference time. When the speaking time of the unit reach to the preset time, it will automatically close; as for the latter, when the whole conference time reach to the preset time, all units will be closed down by the mainframe to better comply with the requirement of the debate.

*Provided with recording access of conference and multichannel audio inlet and outlet 

*Connect to the center control mainframe through 232 port and access all functions of the center control mainframe
