This is the latest generation of this device. I now am having them machined from a single piece of aluminum..This is a new version of a product I have offered previously . These are made to order rack mount splitters . The version pictured is specifically designed for splitting and distributing powered intercom ( PL) circuits as in , clear com or rts , etc. These feature LEDs to indicate presence of dc voltage . I can also make these without LEDs if you wanted a straight splitter panel or I can add transformers or other options . The only limitation is the physical size of the chasis .Please NOTE: These are typically made to order, although I sometimes will make a few extra stock style units when building a batch , I don’t typically keep completed stock units , because of the amount of custom versions that people request ... on occasion , I can ship immediately or nearly so, but often there can be a week or two turnaround time as I’m either waiting on the machine shop or whatever style connector you might order. It gets expensive to keep every possible connector on hand . Please check out my other items listings for my newest related device: Its an thereon based interface for 4 wire intercom use, or, it can be a dual 4 channel thereon based audio snake...!!! NEW !! Note the pictures showing options in terms of color and labeling .. my standard color is red . As of this update. I have two black units and two of the red ones with the “ C. D “ labeling in stock plus a bunch of the normal red a/b style . Other colors are possible , but require a larger quantity and to allow for time .. if I happen to be running a fresh batch I can easily accommodate that , otherwise to make a single “ blue” panel. Is not cost effective ( shop minimums, etc)
