Polycom's Vortex EF2210,
a stand-alone 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.
