I just made a few Mono SBD patch cables for the stone church, a local venue here in New Hampshire. They are real cool about letting us get SBD feeds but the problem is that it's a mone source, which is fine for mixing with audience mics though. The 3 & 4 Channel cables allow for a bunch of us to get a SBD feed with out any fears of Dead Batteries, Level Adjustments, etc that might occur in a daisy chain of recorders. The 1/8'" mini gets a mono feed from the board but records to a "stereo" file.
Mono XLR > Stereo 1/8"
3 Channel Mono SBD Patach Cable: Mono XLR > Mono Chopped R\A XLR & Mono Chopped 1/4" & Stereo 1/8"
4 Channel Mono SBD Patch Cable: Mono XLR > 2 Mono XLRs & Mono 1/4" & Mono RCA
