We use this low-profile omnidirectional condenser boundary microphone in many of our induction loop installations in meeting rooms. It requires phantom power from 11V to 52V which is available on many Room Induction Loop Systems. Audio Technica's design is for clear, highly intelligible sound reinforcement, professional recording and teleconferencing in table, ceiling, or panel mount applications. The microphone has a 3 pin XLRM output connector. Audio Technica’s UniGuard® offers great immunity from radio frequency interference. It is protected by a rugged all metal case with two-layer steel mesh grille, and is available in two colours: black (ES945) and white (ES945W).
