ETS SM1-SDU Surface mount, Covert Smoke Detector Style, Uni-directional Microphone

ETS SM1-SDU High performance, Unidirectional pre-amplified microphone for use where side noise must be reduced. Covert housing designed to appear exactly like a modern smoke detector. Simply mount the SM1-SDU 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. Ivory ABS enclosure Mounts on any flat surface. Connects directly to our switcher / mixer / amplifiers or use one of our many interface products to make fast and clean connections to DVRs or remote monitoring.

Features

• Unidirectional Pickup Pattern: 25′ pickup pattern with reduced (-6db) sensitivity on all sides ensures clear audio capture from the desired direction while minimizing unwanted noise.
