Simple Balanced Audio Circuits Possible with MB-6582?
Posted 04 September 2011 - 04:31
It looks like the circuit should be easy to modify to have balanced outs after the op-amp but is there a way to do balanced connectors for the direct SID outputs without having to use an op-amp? If it was rather simple, I was thinking about using balanced connectors for those as well.
I know it's not necessary for short runs but my next audio I/O solution will likely have balanced XLR connectors so I figured it can't hurt and I'll have plenty of room on the back of my chassis anyway.

That could end up being pretty awesome!

Only good can come out of two minds instead of one right? :-D
Midibox Case Design Competition - time to get it going huh?

I want to go with a modular solution which I could use both for my MBSID and MBFM projects, as well as pretty much anything in the future, although I've gone back and forth on that. I like the modular idea because I can decide how I want to orient the plugs on the back and such and you never know when that might come in handy.
The idea I had was to have direct outs which have a 1/4" jack and resistors to a mix out header. I tap the output of that header into a wire that runs the length of all the direct outs into a final mix out board which has an op-amp or line-driver.
I've included my stereo version of the line-driver mix out but I rather like the idea of making the boards single channel which gives me some interesting options down the line. For my MB-SID, I would just have one row for left and one for right. Not the cheapest option, but I think it might prove to be useful in the future.
Anyways I'm happy to share everything I have. I was going to throw this up on my MB-SID synth wiki page. If you want them before them, just let me know and I can post them here or PM them to you.
I keep tweaking the designs (like going from stereo to mono out) so it's a work in progress )
