The Clear-Com MS-222 2-Channel Main Station is a rack-mount, two-channel main station with a speaker, optional goose neck microphone (MS-222GM), regulated power supply and a versatile monitoring system. It features excellent speech intelligibility in all noise-levels.

The MS-222 contains two mic preamps with limiters for each microphone input. Each microphone preamp is optimized for the type of microphone used with it.

The MS-222's four-watt power amp can drive a standard Clear-Com headset to levels greater than 110 dB SPL.

The MS-222 provides DC voltage and the ability to talk and listen on two separate channels. It supports and monitors two intercom lines containing as many as 30 remote head-sets or 6 remote speaker stations.
The MS-222 Clear-Com 2-Channel Rackmount Main Station may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
