Create A New AccountThe 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. There are a variety of ways in which it may be used. The most common is to provide the manager of a sub-group of the technical staff with an RSM300, provide a connection to the Master Station, and have the rest of the sub-group connected to the RSM300. In this way communications among the members of the sub-group are selective to themselves and do not add to the cumulative clutter on one of the main circuits. Because the RSM300 has 3 circuits and is using only one to communicate 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.
A second application for the RSM300 is to provide 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.

Our full policy is in our Terms and Conditions page.Please Note: Due to unprecedented raw material and component shortages for finished goods throughout our industry, lead times for items that aren't currently in stock are longer than normal and cannot be guaranteed at present. Equipment needed by a firm date must be noted at time of order. While VLS cannot guarantee delivery by those dates, we will work with our suppliers to do everything possible to meet deadlines. We apologize for the inconvenience and appreciate your patience.
Online orders received by noon Eastern time typically ship the same day. If your delivery due date is critical please note your due date in the order messages at checkout, and then contact us.
Why Noon? Well, while we stock quite a few items in our warehouse, many items we have dropshipped by our vendors. They need time to process the order, so to ensure that we can get the order to the vendor and give them enough time to ship it out the same day, we need to get the order to them as early as possible in the day.
Please also note that the shipping rates for many items we sell are weight and dimension based, as this is the method that FedEx and UPS use to rate the package's cost to ship.
We understand things happen and items occasionally need to be returned. To make things as hassle-free as possible, we have dedicated pages about our Returns Policy (what’s eligible to be returned) and our Return Process (how to go about returning eligible items)
