The ACBMIC is a directional electret boundary layer microphone. It is designed to be connected to unbalanced microphone inputs with bias powering such as those found on the Ampetronic ILD100 and CLD1 induction loop amplifiers. The unit is directional when properly mounted, so it can reduce unwanted sound pickup from sources that are not in front of the microphone.
