About the
EF2211/EF2210
The EF2211/EF2210 features industry-leading acoustic echo cancellation technology,
which keeps received audio from being re-transmitted to its original location, and pat-
ented noise cancellation algorithms which dramatically reduce ambient noise in the
audio sent to other sites without affecting speech quality.
Also included in the microphone input is a neural network Automatic Gain Control
that reacts only to valid speech patterns to bring voices within desired levels. AGC
controls are user-adjustable, as are settings for the 5-band parametric EQ offered on
all input and output channels in the EF2211/EF2210.
The EF2211 includes a telephone interface with ambient noise cancellation, which
can dramatically improve the receive audio quality on phone calls.
The EF2211/EF2210 may be programmed directly from the front panel, or through
our Conference Composer software (included), which programs the unit via RS-232.
The unit may additinally be controlled via external RS-232 devices.
