Audix UEM81s Battery Powered Shotgun Condenser Microphone
The Audix UEM-81s is a shotgun microphone capsule with a super-cardioid polar pattern. The microphone is designed for accurate signal reproduction at long distances or noisy environments. The super-cardioid pattern offers the highest rejection of off-axis signal, resulting in exceptional signal-to-noise ratio and reproduction of the desired source.
The UEM81s features a low-frequency roll-off filter. The microphone is powered with a single AA battery, and is flexible enough to capture audio in video shoots, recording applications and sound reinforcement applications.
