Clear-Com

Figure 3.7 Clear-Com®based training intercom system.

It just happens that the Clear-Com®system is the simplest for this application, since the Master Station, MS-812A has the three pin XLR connectors for 12 channels on the rear panel. The MS-812 has several configurations, and will have to be specified for this application (No IFB, 12 Clear-Com standard PL channels).

Power Supply: PS-464.

Instructor’s Station: MS812A.

Students’ Stations: Single Channel Belt Packs RS-501.

Instructor’s Headset: Single Muff CC-95.

Students Headsets: CC-250.

Cables: Standard Microphone Cables with XLR-3 connectors. One cable per channel.
