Easily add phone calls and improved acoustic echo
cancellation to your rollabout or installed conferencing
applications.
Existing conferencing installations will benefit from improved audio clarity and reduced noise, resulting in more
effective communication between sites.
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 (ACG) reacts only to valid speech patterns, bringing
voices within desired levels. The EF2211 may be programmed directly or though Polycom's Conference
Composer software (included). The unit may also be controlled via external RS-232 devices.
