Re: [motm] Output Mixers and other ideas & questions
2002-09-02 by J. Larry Hendry
Well, certainly for me, basic op amp mixer circuits are as easy as it gets. I like the idea of an output mixer as well. But, I have a question for P.S., J.H. or those easily more qualified than me. Is there a functional limit to the number of input connections for an op-amp in a standard summing inverting mode? We see 3 and 4 all the time. But, what about 8 or 10. Does that work just as well? Or, does one reach a point where two the number of inputs justifies dividing them between a couple of summing circuits and then summing the output of those? Larry (just a Stooge, not an engineer)

I've tried using a Samson 16 x 2 mixer in a 2 rackspace unit with a headphone out. Unfortunately the Samson mixers are the only units I have found which refuse to coexist with the balanced line AC in my studio. They hum like crazy. For recording I go straight from the alst module into my Apogee converter. I'd like to see an output module with a headphone amp and balanced line outs. Two outputs would be enough for most people but perhaps more would be nice to have for those MOTMers who like to perform live with multiple speakers. An input module would be nice as well. I'd like to see a mic input preferably with phantom power available as well as a couple of line level inputs. Maybe it could include a follower. A third idea would be to possibly adapt one of those low cost tuners like the Korg into a tuner module, possibly with an A440 reference as well. Idea number 4 would be a universal buffer module which could adapt ins and outs from rack mount units like delays and effects into MOTM level signals. Sort of like Stooge Moe's buffer for the expressionist. Just throwing ideas out there. So many ideas and so little time. Paul Haneberg Your use of Yahoo!
