ProMix
Above is a two-piece, custom built, 3-way splitter built for ProMix of Las Vegas, Nevada.
There are two switches next to each XLR input that lift the ground of each individual isolated output.
This panel is connected by three hard-wired umbilicals to three W4 MASS connectors. These W4s are mounted on hinged angle adapters that allow the connecting cables to hang down at a 60-degree angle but fold up and lock out of the way for storage and transport.
