Full-duplex speaker Up to 3 SIP identities with simultaneous call management. Bluetooth and DECT technology allow compatible devices as well as smartphones to be connected. Snom HD Voice Up to 70 hours of standby time 3yr Warranty The Snom C520 is a modern and cost-effective conferencing solution for enterprises of any scale. 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. Connectivity is now one of the most important factors for effective collaboration. This is why the C520 features a versatile Bluetooth interface allowing smartphones or DECT phones to be easily paired and used. To extend the C520 conference system across even larger areas, simply couple wireless C52 loudspeaker units to the base unit and the range of the loudspeakers and microphones will be increased greatly. With its modern and sleek design, the C520 fits seamlessly into your working day. Two detachable DECT microphones can be positioned freely or carried in the room as required to ensure the best sound and voice quality. Built-in charging stations with magnetic bays directly on the base station mean both microphones are always charged and ready for use in the next meeting. The conference phone also features automatic volume control and digital noise reduction so that all call participants can be understood with the sound quality. The Snom C520 grows to meet your demands: Even the largest conference rooms can be connected to the base station with the addition of up to three C52 wireless speaker units for a significant increase in range.
