Seismic Audio Rack Mount Stage Snake SARMSS-16x1530 with 13' and 28' trunks. I converted channels 9 thru 16 of the13' trunk to 1/4" TRS male connectors (see detail photo) so I could use my JamHub (NOT INCLUDED) as a recording monitor. Channels 1 thru 8 of the13' trunk outputs and all channels of 28' trunk are the original male XLS connectors. Maybe this configuration will work for you? All 16 inputs allow for either XLR or 1/4" TRS input for flexibility not found in older stage boxes.

Used in studio only, and very briefly. After my band got our demo tracks cut it has sit around collecting dust, so it's time to let it go. Goes for $249 new at Seismic Audio (although they tout 15' and 30' trunks on theirs. Maybe I should have pulled harder when I was measuring? :D), so this is a steal at $99.
I want you to be happy with your purchase, so I offer a full refund if returned in as-sold condition within 48 hours so you can be sure it is compatible with your gear.
