Omnidirectional Condenser Boundary Microphone

ES945O/TB3

Designed for surface-mount applications such as conferencing, recording, monitoring, and other demanding sound pickup applications

Low-profile element provides uniform omnidirectional polar pattern with 360° acceptance angle

Miniature, space-saving design enables highly inconspicuous tabletop, ceiling, and wall mounting

Self-contained power module with TB3M (mini-XLR) output connector

Includes a TA3F-to-XLR cable for use with standard XLR inputs

Rugged all-metal case with a two-layer perforated grille

Rubber Isolators provide mechanical dampening of mounting-surface vibration

Requires 11V to 52V DC phantom power

UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)

With its low-profile design that mounts unobtrusively in tabletops, ceilings or panels for minimum visibility, the ES945O/TB3 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 steel mesh 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 integral power module can be powered from any external 11V to 52V DC phantom power supply.

The ES945O/TB3 is equipped with a self-contained power module with a TB3M (mini-XLR) output connector, eliminating the need for an external power module. The power module can be powered from any external 11V to 52V DC phantom power supply. It also comes with a TA3F-to-XLR cable, allowing for installation with standard XLR inputs. The microphone is black colour, and comes with a pair of rubber isolators for optional mechanical isolation from the mounting surface.
