Pre-polarized shotgun condenser, battery powered.
This UEM81S is a pre-polarized condenser microphone used for stage, studio, video and broadcast applications. This mic is conveniently powered by one AA battery; it is not dependent on phantom power for operation. Exceptional sound quality, accurate response and ability to pick up from a distance, the UEM81S is designed to be aimed at the sound source to capture those "hard-to-get-to" places: theatre, stage, sporting events and outdoors.
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 ambient noise.
