Microphone Mixer
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.For a complete listing of commands
