UEM81S

The UEM81S is a pre-polarized condenser microphone used for stage, studio, video and broadcast applications. The UEM81S is conveniently powered by one AA battery; therefore it is not dependent on phantom power for operation. Known for its exceptional sound quality, accurate response and ability to pick up from a distance, the UEM81S is designed to be aimed directly at the sound source and can help capture those “hard to get to” places in a theatre, on a stage, in a sporting event or in the outdoors. Characterized with a uniformly controlled supercardioid polar pattern, the UEM81S is designed to capture the acoustics of a vocal or instrument while at the same time isolating it from the rest of the ambient noise on stage or in a video shoot. With a wide frequency range of 20 Hz – 20 kHz, the UEM81S is equipped with an on-off switch as well as with a bass roll-off switch. The UEM81S is very easy to position, durable and manufactured to high standards and tight tolerances. Roadworthy construction includes a machined aluminum body and capsule housing, black e-coat finish, interchangeable threaded capsule and snap to fit composite clip.
