The C520 is the perfect companion for collaborative teamwork, thanks to its modern DECT and Bluetooth technology. This advanced conference phone features three highly developed microphones. One microphone is built into the base unit along with a powerful full-duplex speaker. Two additional cordless DECT microphones can be placed freely in the room or carried around.

The microphones of the C520 are equipped with dynamic noise reduction and adaptive feedback control for crystal-clear HD voice transmission, even in the presence of many people or in large spaces. To ensure optimal coverage, the microphones synchronize in real-time based on their position in the room. This technology allows users to move freely within the space without having to raise their voices, regardless of the size of the meeting room.

Connectivity is one of the most important factors for effective collaboration today. Therefore, the C520 features a versatile Bluetooth interface that allows mobile or DECT phones to be easily paired and used.

The C520 conference system can be expanded as needed to cover larger spaces. Additional C52 speaker units can be wirelessly paired with the base unit, significantly increasing the range of the speakers and microphones.
