This is TT or Bantam style patchbay often used for a recording studio or tv studio. It has some cables with ends soldered on and some cables are just cut off. It was in a studio setting. I bought it hoping Id have my own studio someday, but I need my equipment to work for live music too so this patchbay doesnt make sense for my application.
Great way to save wear and tear on gear and do all the plugging and unplugging on this instead.
