One of my favorite parts of working in SoundTools sales is talking with customers about application ideas and solving common audio problems using SoundTools products. Recently I got a chance to test using CAT Boxes and the SoundTools SuperCAT cable to send COM signal over 750 feet. The end result was impressive!

he application needed to be able to have multiple access points along the route, every 100 feet or so, using the parallel out on the CAT Box, making the COM signal available on input 1 all the way down the line. This would allow operators at various locations to tap into the CAT Box and be able to join the communications channel.

We started with the minimum spec, added several CAT boxes and about 1000 feet of SoundTools SuperCAT cable (purple, my favorite flavor) and 4 COM handsets with packs.
