Re: Mid Side M-S Matrix Construction Information

Sure enough. The right input wasnt making full contact. Reseated the cable and its crystal clear! :? Great job on this btw! Is there any benefit to rigging the jumpers to switches? From what i understand this would bypass the various stages (or would it just mute them?) Thanks much for the reply. Th...

Re: Mid Side M-S Matrix Construction Information

I just about finished the build... gotta tie up some loose ends. I tested it out last night after getting the jacks wired up. Is there any kind of dummy test I can do to make sure everything is working properly. I think i may have a phase issue somewhere (possibly a reversed set of wires). I took a ...

Re: Mid Side M-S Matrix Construction Information

http://www.meirecords.com/images/schem1.jpg This is the schematic for the most part for the VU circuit. EDIT: Disregard the bottom half circuit design its ALL sorts of wrong What sucks is i just realized that the KA chip only handles up to 16V... doh. I guess i could put a voltage resistor in there...

Re: Mid Side M-S Matrix Construction Information

thanks for the link. :) I planned on doing a small pre and post VU meter (LED) probably only 5 segments each (so like 20 LEDS) I dont know if that counts as a lot of lights. Im also still not decided on if i should integrate this with a analog sum box im designing. Im leaning toward keeping this a s...

Re: Mid Side M-S Matrix Construction Information

Are the values i put in the top of this schem for the PS ok. L1 is an LED not what is listed and the resistor R7 after that can be from 1K to 10K. http://www.meirecords.com/BJ/01-PSU_Schematic.jpg also, what transformer should go with this (running at the recommended 18v) should i go higher than som...
