Clear-Com RM400 4 Channel Communication Remote Station

The RM-400 is a four-channel remote speaker station with a versatile channel-monitoring system, featuring excellent speech intelligibility and consistent high performance. The RM-400 contains a mic preamp and a four-watt power amp, so it can drive two dynamic headsets and the built-in speaker or an external speaker. The Station drives a standard Clear-Com headset to levels greater than 110 dB SPL. The built-in speaker outputs crisp sound pressure levels, high enough to be heard in the noisiest surroundings.
