RS232 controllable microphone switcher / mixer for remote monitored audio surveillance systems. The SM8-RC connects to video/audio transmission equipment (with an available RS232 port) that uses telephone, Internet or LAN mediums. The SM8-RC fills a need when the transmission equipment lacks a sufficient number of microphone audio inputs and switching / mixing capabilities. Programming is required by the remote equipment manufacturer to control the SM8-RC via RS232. The SM8-RC

Powers up to eight SM1 pre-amplified microphones and outputs a line level audio signal. The SS8-RC can be expanded to 32 microphone zones by looping connections from an SM8-RC to up to 3 additional SM8-RCs. Simple ASCII commands control the SM8-RCs via RS232.See www.etsnm.com for a complete listing of the commands.
