The mini stereo plug I bought for the mixed output of the MB6582 is crap. I might replace it with a better one, maybe 1/4", and try using the mixed output. I remember reading that a few people highly recommended against that. Why?
I still need to build the case, but I have bought a four channel multicore insert cable - it has four stereo plugs going to eight mono plugs which will be connected to a patchbay.
I don’t think the mixed output on the MB6582 is crap at all. It’s just passively mixed so it’s a bit more quiet compared to the direct outs. That plus you can’t control the volumes of each output or anything. But for what it is, works great! I don’t think I would use it for recording but apart from that it’s a good every-day output and is certainly convenient if you don’t have 4 stereo inputs on your audio device to dedicate to all 4 SID pairs.
Well out of the view of a audiotechnican it should be a XLR for each Channel any time. So the tech. can take care of different Speaker setups. (witch men, that your Headphone or Monitor may have a different sound than a PA)
But i understand that thats not a small connector and by making sound at home Jack is more common. Because cheap mixers have separated Line Inputs on Jack and just the Mic Pre is a XLR.
Thes actualy have 3 Contacts so it is possible to make a Stereo Plug out of one but it is not mentioned as that. They are thought to wire symmetrical… Balanced Audio on Wikipedia
