These are mostly made for audiophiles, but I've also done bespoke work for professional deejays, audio and video editing houses, film production crews, custom home and business installations, and movie productions. Feel free to contact with whatever you need, if the pin-outs are not on hand I'll do the research, or feel free to provide schematics, drawings, or bar napkin scribbles. I tend to enjoy custom projects and often document them on diyaudioblog.com, so don't hesitate to contact me.
