Water-resistant Omnidirectional Condenser Boundary Microphone with XLR Output

ES945O/XLR

Overview

ES945O/XLR

With its low-profile design that mounts unobtrusively in tabletops, ceilings or panels for minimum visibility, the ES945O/XLR omnidirectional condenser boundary microphone provides clear, highly intelligible audio that is perfect for conferencing, recording, monitoring and other demanding sound pickup applications.

Protected by a rugged all-metal case with a two-layer perforated grille, the microphone’s omnidirectional polar pattern affords a 360° pickup angle, while its UniGuard® RFI-shielding technology provides outstanding rejection of radio frequency interference (RFI). The microphone also offers IPX4 water resistance to protect it from splashes of water.

The ES945O/XLR is equipped with a self-contained power module with an XLRM-type output connector, eliminating the need for an external power module. The microphone is available in black (ES945O/XLR) and white (ES945WO/XLR), and comes with a pair of rubber isolators for optional mechanical isolation from the mounting surface.
