High performance, Unidirectional pre-amplified microphone for use where side noise must be reduced. Simply mount the SM1-ULE in the direction of interest. Built in limiter circuit automatically lowers the output level during loud sound intervals. Selectable lo-cut and hi-cut filters significantly reduce background noise. ABS enclosure Mounts on any flat surface.
