SM5-TR Kit


High performance, Omni-directional, pre-amplified microphone for fixed location security 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. 25’ pickup pattern in all directions. Built in limiter circuit
automatically lowers the output level during loud sound intervals. Hi cut and
low cut filters significantly reduce background noise. Stainless steel plate
mounts flush or on a single gang electrical box.
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.
