Product overview
The SONODYNE SYNC 3001 is the chairman base unit of the SYNC IP based digital conference system, with a 2.23 inch OLED display, illuminated touch buttons, a priority button and approval of delegate speech requests.
The SYNC 3001 is the base of the chairman conference unit: the SYNC 2001 (500 mm) or SYNC 2002 (420 mm) gooseneck microphone screws onto it to form the complete unit. It is powered by the SYNC 1001 controller over a T-type 8 core cable shielded by full-line aluminium foil, and its hand in hand connection supports hot plugging. The chairman unit is not limited by the number of speakers, can be connected anywhere in the loop, and the system supports several chairman units at the same time.
