Self Monitoring System

I needed a headphone monitoring system at the studio and didn't have the funds to buy a complete system. Necessity is of course the mother of invention. After a couple revisions, I now have the SMS-1B.
The SMS-1B is a remote passive headphone volume controller. The input is balanced XLR and the output is a standard headphone jack. Back in the control room are a couple headphone amps cranked all the way and wired through our patch bay to the live room. The outputs on the live room wall are XLR male so we can use them for a variety of scenarios (like re-amping). The remote box allows us to run super long distances with high quality mic cables, vs those crappy headphone extension cables. Also the box allows the musician to have control over their monitoring volume.
