Description:

Thanks to advanced DECT and Bluetooth technology, the C520 is the perfect device for team conferencing and offers three cutting-edge microphones. The first of these is built into the high-performance full-duplex speaker in the main base station with two further wireless DECT microphones that can be freely placed or carried in the room as required.
The C520 microphones use dynamic noise reduction and adaptive feedback control to provide crystal clear HD audio transmission, even in crowded or spacious rooms. The microphones synchronize with the base station in real-time according to their location. This technology allows the user freedom of movement without even having to raise their voice – regardless of meeting room size.
