Description
The SM5-LE2 from ETS is a 1 SM1-LE2 microphone, SM2 interface. The SM1-LE2 is 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.
The SM2 is a single channel interface for use with all SM1 series microphones. It provides a convenient way of supplying
power to the SM1, installer friendly termination of the cable runs and a standard RCA or 3.5mm audio output connector. The SM2 easily connects to recording equipment such as DVRs, I/P cameras and audio recorders. Note the audio output signal of the SM2 is “line level” (0dbm).
