The Audio-Technica ES945O/XLR is a water-resistant omnidirectional condenser boundary microphone with an XLR output designed for clear audio pickup in conferencing and recording applications.
The Audio-Technica ES945O/XLR is a water-resistant omnidirectional condenser boundary microphone designed for surface-mount applications. This low-profile microphone provides clear, highly intelligible audio for conferencing, recording, monitoring, and other demanding sound pickup scenarios. Its unobtrusive design allows for mounting in tabletops, ceilings, or panels to maintain minimum visibility.
The ES945O/XLR features an omnidirectional polar pattern that delivers a uniform 360° acceptance angle. This wide pickup range ensures consistent audio capture from all directions around the microphone. The condenser element is engineered to provide high intelligibility, making it an effective solution for professional communication environments.
Built for longevity, the microphone is housed in a rugged all-metal case with a two-layer perforated grille. The ES945O/XLR carries an IPX4 water-resistance rating, which protects the internal components from splashes of water. This durable construction allows the microphone to perform reliably in various installation settings.
To ensure clean signal transmission, Audio-Technica incorporates UniGuard RFI-shielding technology. This feature provides outstanding rejection of radio frequency interference (RFI) from external devices. Additionally, the microphone comes with a pair of rubber isolators. These components provide mechanical dampening to reduce the pickup of mounting-surface vibrations.
The ES945O/XLR utilizes a self-contained power module with an integrated XLRM-type output connector. This design eliminates the requirement for an external power module, simplifying the installation process. The microphone operates on 11V to 52V DC phantom power. The unit is RoHS compliant and is available in both black (ES945O/XLR) and white (ES945WO/XLR) finishes to match different architectural aesthetics.
