Polycom's Vortex EF2211 improves the overall audio quality of existing conferencing installations, and can also be used as a standalone system for individual sites. The unit is typically utilized in meeting rooms, along with one or more microphones and an automatic microphone mixer. A telephone interface with ambient noise cancellation can dramatically improve the receive audio quality on phone calls, and the 10-watt power amplifier drives small loudspeakers in the room.
Because the EF2211 delivers robust acoustic echo and noise cancellation performance, it is often used instead of the video conferencing codec's microphone and acoustic echo canceller. Industry-leading acoustic echo cancellation technology prevents received audio from being retransmitted to its original location. Patented noise cancellation algorithms dramatically reduce ambient noise in the audio sent to other sites. User-adjustable, neural network Automatic Gain Control (AGC) reacts only to valid speech patterns, bringing voices within desired levels.
