I will be buying a QSC 1202 which I plan to run mono using a Speakon connector to a cab...I know I need to re-wire the cable for mono. I've looked up the information and, although I've found some info, I have yet to find a detailed, easy to read diagram on how to do this. Is it hard? Does it have to be re-wired from both ends? Also, if I have 2 8 ohm cabs that I want to run in parallel (4 ohm mono), how would I wire it using only one speakon cable? Thanks in advance.
