SKU: ETS-SM1TR-Microphone Flush Mount Tamper-Resistant Microphone SM1-TR

ETS Stainless Steel, Flush Mount, Tamper Resistant Omni-directional Microphone SM1-TR

High performance, omni-directional pre-amplified microphone for use in applications where vandalism is of concern. Electret element is mounted in a special housing which is out of reach to objects inserted into the sound holes. Built in limiter circuit automatically lowers the output level during loud sound intervals. Selectable lo-cut and hi-cut filters significantly reduce background noise. Stainless steel plate mounts flush or on a single gang electrical box.
