ETS SM1-SS-MS Omni-directional Pre-amplified Microphone with Mute Switch

The SM1-SS-MS from ETS is a high-performance, omni-directional, pre-amplified microphone designed for fixed location security applications. With a 25-foot pickup pattern in all directions, it excels in capturing audio in any environment. Its built-in limiter circuit ensures clear sound by automatically lowering the output level during loud intervals, while hi-cut and low-cut filters effectively reduce background noise. The integrated mute switch allows for easy control of audio output, complemented by a two-color LED indicator for status. It also mounts flush or on a single gang electrical box, making installation straightforward and versatile.
