The latest from Sonifex Redbox line of broadcast problem solvers is the RB-AEC, an acoustic echo canceller designed for snuffing out annoying echoes in earpieces.

Sonifex explains, �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.�

According to the company, the 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. Although acoustic echo cancellation is more commonly implemented in telephony systems, the Sonifex RB-AEC is designed to produce broadcast quality cancellation.�

The RB-AEC�s onboard digital signal processing can adapt to shifting situations, such as personnel moving around, to keep the echo tamped down.
