Audio-Technica ES945O/TB3 Miniature Omnidirectional Condenser Boundary Microphone with TB3-to-XLR Output

The Audio-Technica ES945O/TB3 is a miniature omnidirectional condenser boundary microphone designed for high-quality sound pickup in space-constrained environments. This low-profile microphone provides a clean and inconspicuous look for conferencing, recording, and monitoring applications. It mounts directly into tabletops, ceilings, or panels to deliver clear and intelligible audio while maintaining a minimal footprint.

Superior Audio Performance and Coverage

The ES945O/TB3 uses a low-profile element to provide a uniform omnidirectional polar pattern. This 360° acceptance angle ensures comprehensive sound capture from all directions, making it ideal for group conferencing and environmental monitoring. The microphone delivers high intelligibility for demanding sound pickup tasks while occupying significantly less surface area than standard boundary microphones.

Durable Construction and RFI Shielding

Built to withstand professional use, the microphone features a rugged all-metal case. A two-layer steel mesh grille protects the internal condenser element from damage. To ensure signal integrity, the ES945O/TB3 incorporates UniGuard RFI-shielding technology. This feature provides outstanding rejection of radio frequency interference (RFI), protecting the audio feed from external electronic noise.

Installation and Connectivity

The ES945O/TB3 simplifies integration with its self-contained power module and TB3M (mini-XLR) output connector. This design eliminates the need for an external power module. The microphone requires 11V to 52V DC phantom power for operation. For compatibility with standard professional audio equipment, the system includes a TA3F-to-XLR cable to facilitate connection to standard XLR inputs.
