Audio Technica ES961 Cardioid Condenser Boundary Microphone

Wikispecs.org - The Largest Product Database,the biggest product specifications database in the world

The new Engineered Sound. Contractor-exclusive innovations for every acoustical challenge. And safe haven from RFI.

Featuring breakthrough audio and mechanical design innovations, the phantom-powered ES961 offers outstanding speech intelligibility and transparent sound quality for surface-mount applications. The microphone is equipped with a PivotPoint® rotating output connector, UniSteep® filter and UniGuard® RFI-shielding technology. It accepts interchangeable condenser elements—available for boundary microphones in cardioid, hypercardioid and omnidirectional polar patterns. With a heavy die-cast case and silicon foam bottom pads to minimize coupling of surface vibration to the microphone, the ES961 is equipped with self-contained electronics, eliminating the need for an external power module. Designed for surface-mount applications such as high-quality sound reinforcement, professional recording and teleconferencing

PivotPoint® rotating output connector allows cable to exit from either the rear or the bottom of the microphone

Superior off-axis rejection for maximum gain before feedback

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

Self-contained electronics eliminate need for external power module

Small-diameter UniPoint® capsule near boundary eliminates phase distortion and delivers clear, high-output performance

Heavy die-cast case and non-slip silicon foam bottom pads minimize coupling of surface vibration to the microphone

Requires 11V to 52V DC phantom power

Low-profile design with low-reflectance finish for minimum visibility

Available in two colors: black (ES961) and white (ES961W)

RoHS compliant—free from all substances specified in the EU directive on hazardous substances
