Sonifex RB-AEC Acoustic Echo Canceller (1 RU)

The 1 RU RB-AEC Acoustic Echo Canceller from Sonifex is designed for the benefit of studio personnel for television and radio. When a studio presenter's microphone signal is played out through a monitor speaker in the control room, it can be picked up by the control room microphone(s) and returned to the presenter's earpiece as an undesirable echo. In circumstances where green screen video processing is taking place, the delay can be greater than 200ms and the dimensions, occupancy, and distance between mouth and microphone can further influence the echo. The RB-AEC is used to remove the entire control room monitor speaker output from the presenter's feed by adapting to the environment in which the control room microphones are placed.
