Polycom Vortex EF2210 User manual

Industry-leading acoustic echo and noise cancellation make
the Vortex EF2210 a natural for installed conferencing systems.
Whether you need to add echo and noise cancellation to an existing installation, or want more robust audio
performance, the EF2210 provides clear, natural sound that will enhance the productivity of your conferences.
Audio and video conferences depend on high-quality audio. Polycom's Vortex EF2210, a standalone system
for individual sites, is typically installed in meeting rooms along with one or more microphones and an
automatic microphone mixer. Because the EF2210 delivers robust acoustic echo and noise cancellation
performance, it is often used instead of the video conferencing codec's microphone and acoustic echo
canceller. It provides a single microphone or line level input, plus two auxiliary inputs (for external devices
such as a VCR). If additional microphone or line inputs are required, the Polycom Vortex EF2241 or
Vortex EF2280 models are recommended.
The EF2210 features industry-leading, acoustic echo cancellation technology, which 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, without affecting speech quality. User-adjustable, neural
network Automatic Gain Control (ACG) reacts only to valid speech patterns, bringing voices within desired
levels. The EF2210 may be programmed directly or though Polycom's Conference Composer software
(included). The unit may also be controlled via external RS-232 devices.
