The C520 is the perfect companion for collaborative teamwork, thanks to its modern DECT and Bluetooth technology. This state-of-the-art conference phone features three advanced microphones. One microphone is integrated with the powerful full-duplex speaker in the base unit, while two additional cordless DECT microphones can be freely placed or carried around the room.

The microphones of the C520 are equipped with dynamic noise reduction and adaptive feedback control for crystal-clear HD voice transmission, even with 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 needing 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 for easy pairing and use with mobile or DECT phones.

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