[OPEN-BOX] Audio-Technica ES947C/TB3 Mini Condenser Boundary Microphone

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.

Protected by a rugged all-metal case with a two-layer steel mesh grille, the microphone’s cardioid polar pattern affords a 120° pickup angle, while its UniGuard® RFI-shielding technology provides outstanding rejection of radio frequency interference (RFI).

The ES947C/TB3 is equipped with a self-contained power module with a TB3M (mini-XLR) output connector, eliminating the need for an external power module. It also comes with a TA3F-to-XLR cable, allowing for installation with standard XLR inputs.
