Description
The SM1-LE2 from ETS is a Low cost, High performance, Omni-directional, pre-amplified microphone for fixed location security applications. 25’ pickup pattern in all directions. Built in limiter circuit automatically lowers the output level during loud sound intervals. Selectable Hi cut and low cut filters significantly reduce background noise. ABS enclosure mounts on any 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 equipment.
