 The flexible and mobile extension speaker


For those who regularly hold telephone conferences in large rooms or with many people, the Snom C52 SP is the perfect solution as an extension of the Snom C520 WiMi. The Snom C52 SP can be placed in rooms up to 50m away with the wireless DECT radio technology. Thanks to the two integrated microphones and the powerful loudspeaker, the device acts as a high-quality speakerphone with crystal-clear sound.

A total of up to 3 C52-SP can be wirelessly paired with one Snom C520 WiMi. Due to the fully automatic voice synchronisation of all microphones, every participant is clearly understood. In addition, the device has an extremely powerful battery that can easily provide up to 12 hours of talk time.

By the way, it can also be connected wirelessly with the Snom A230 DECT USB dongle to any Snom desk phone that has a USB interface, providing a cost-effective and flexible conference solution.
