This is an MC6, a 6-channel DMX light controller for stage lighting. It is being sold as junk because its functionality hasn't been confirmed in its current state. It was working about a year ago, but I didn't quite understand how to control it, so I've been storing it. I have confirmed that it powers on and that the on/off buttons light up. There are many scratches and signs of use. [Specifications] • Number of channels: 6ch • Sound sensor equipped (sensitivity adjustable) • DMX output terminal: XLR type [Included items] • Only the main unit and adapter
