1 System Composition
2 System Function Traits
1) The system has the function of limiting the quantity of delegate unit, can choose the limit address type directly , such as "1", "2", "3", "5"or "free". When choose "1" or "2" or "3" or "5", the delegate unit which opened at the same time can not excess the quantity choose, when reach the chosen quantity, besides the delegate unit is turned off or the chairman unit press the preferential key, or else the new delegate unit can not be opened; when choosing "1", it can answer before others.
2) There is no limitation for the chairman unit, it can open at any time.
3) Press the preferential key to close the whole delegate units which need to re-press the key to speak.
4) Every conference main unit can drive up to 80 units, and can drive over 200 units by adding expansion main unit.
5) Internal feedback restraint circuitry; set up alt/ bourdon digital adjust circuitry, so as to adjust system’s timbre independently; also can adjust the volume;
6) With balance circuitry output interface, also left/right circuitry output interfaces and unbalance output interface, so as to adapt the connection of each kind of equipment.
7) Use the imported Panasonic microphone cartridge. We can talk to the microphone at the distance of 450-500mm without howling.(Matching the same brand equalizer to use)
