The AVer VC520 PRO Expansion Speakerphone is designed to increase the microphone pickup range and audio coverage of the VC520 PRO Video Conferencing System. This conference system features a strong speaker and a mic that takes up voice inside 360° at up to 15', allowing you configuration versatility in conference rooms and classrooms independent of room design or seating arrangements.
You may daisy-chain this Expansion Speakerphone to the speakerphone that comes with the VC520 PRO video conferencing system to achieve a 30' voice-pickup radius and avoid crowding around one speakerphone. You may daisy link a second Expansion Speakerphone for a total of three speakerphones and a 45' voice-pickup radius in larger venues.
All units in the chain have full speakerphone control, including mute/unmute, volume up/down, call answer, and call hang-up. There's a 33-foot Cat 6 speakerphone cable included.
