Fantastic high-quality speaker phone that bridges analog PBX and USB-based video conferencing.Mark C.Amazon Reviewer
Audio quality is excellent even when the speaker was 10-12 feet from the base unit. Sound quality in the room has been excellent as well over both analog calls in Zoom video meetings.Mark D. CarlsonAmazon Reviewer
The ability to connect multiple units together to work as a single system. This enables larger coverage and scalability.
Power Daisy Chaining
The ability to connect multiple units together to work as a single system with one power source. This enables larger coverage and scalability.
Offering multiple interfaces in a single product. This feature allows the use of one product in a room that requires multiple connectivity options (audio and video conferencing).
The ability to connect two calls from different interfaces simultaneously, making your video conferencing participants able to speak with your audio conferencing participants as well as yourself through your device.
The ability to recognize the direction of the person speaking in the room.
The ability to steer the directionality of the device’s microphones. Beamforming improves noise and echo cancelling as well as the overall quality of the device’s pickup. This feature works in conjunction with direction finding.
LEDs indicate the voice pickup and direction as well as muting.
