Speaking of... my TENS has an audio input. Without prior investigation I was unprepared to use that feature at the club. Can you tell me what sort of connection I would need to get an audio feed from a typical DJ booth setup, assuming the DJ and/or host are willing, that is. I could connect to any sort of headphone or monitor output, if there is such, with the appropriate adapters. As I understand it, what the DJ hears in their own headphones is often not what is being played over the sound system, so simply splitting that would not work.
