The Pro Intercom RSM300 is a sub-master station powered by the system's master station (MS301) and is connected to one or more of the MS301's communications circuits. It is designed for use in a wide variety of ways available. The Pro Intercom RSM300's most common use is for providing the manager of a sub-group of the technical staff with an RSM300, providing the connection to the Master Station, and have the rest of the sub-group connected to the RSM300. In this way, the members' communication of the subgroup are selective to themselves and don't add to the cumulative clutter on one of the main circuits.  Because the Pro Intercom RSM300 has 3 circuits and uses only one for the communication with the Master Station, it can have two separate sub-groups of its own. For example, a Lighting Director may want to have his automated lighting staff on one circuit, and the follow-spot operators on another.

The other application of the Pro Intercom RSM300 is providing one or more sub-masters which include all of the circuits and functions of the MS301 Master Station, lacking only the ability to control the distribution of Program Audio. This is done by simply connecting each of the circuits of the RSM300 to one of the circuits of the MS301 where each will share communications with the stations connected to that circuit. The operators would be sharing the activities of the main director. This could be useful in a very large system where the Main Director has assistants who have physically different positions and views. This could be true in a competition, or any event where judging is taking place.
