Audio-Technica has taken its low profile ES947C cardioid boundary microphone and given it an even smaller footprint, making it a great choice for installations with limited space or where a very clean, inconspicuous look is desired. The miniature ES947C/TB3 still gives you the same clear, highly intelligible audio of its larger sibling, mounting unobtrusively in tabletops, ceilings or panels for conferencing, recording, monitoring and other demanding sound pickup applications
Designed for surface mount applications such as conferencing, recording, monitoring and other demanding sound pickup applications
Low profile element provides uniform cardioid polar pattern with 120° acceptance angle
Miniature, space saving design enables highly inconspicuous tabletop, ceiling and wall mounting
Self contained power module with TB3M (mini XLR) output connector
