I saw this mentioned in another thread briefly and I can't remember where now. I would like to give my theater the opportunity to have wireless music control from a phone. I would like to be able to give the controller (mostly myself) the ability to plug into a Shure beltpack so I can walk around the space while maintaining control. I looked at purchasing a cord for this but all of the reviews seem to say they didn't work. Can this be wired directly? I don't mind soldering something up. I can't find a good pinout example for this. Am I missing something? Does it need to be pre-amped? Thanks in advance.
