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 patented 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.
