Flush-mount Uni-directional Pre-amplified Microphone

High performance, unidirectional pre-amplified microphone for use where side noise must be reduced. Simply mount the SM1-U in the direction of interest. Built in limiter circuit automatically lowers the output level during loud sound intervals. Selectable low-cut and hi-cut filters further significantly reduce background noise. Flexible plastic plate mounts flush or on a single gang electrical box. Connects directly to ETS switcher/mixer/amplifiers to make fast and clean connections to DVRs or remote monitoring equipment.

note: It is the responsibility of the installation company and end user to install this audio surveillance equipment in compliance with state and federal privacy laws. If you are unfamiliar with these laws, consult a qualified attorney
