dircect outs on an auditronics 110 console
« on: December 08, 2007, 05:13:16 AM »
I would like to fit my auditronics console with transformer-balanced direct outs. I would like to have them switchable between pre-fader(and e.q.) and post-fader(and e.q.) if possible. I would like it to not affect my normal mix bussing. Here are the schematics for the input modules and the output amplifiers - I dont know if i will have to have an amplifier stage to drive the direct outputs?

Any help or suggestions would be appreciated - im very new at this. thanks, ben

take a look at the solo audio points, the pre and post fader signal is available right there. To feed a transformer out, you will need a driver circuit (like another console output card), or feed it into a balanced output chip like a 1642.....
did you get it fired up yet?

oh, if your modules have the a/b input , you could use one of those switches for the d/o....& switch inputs at the patchbay!

hey nielsk - yeah, i saw those solo points. I may just mount the switches on the back panel, as i shouldn't need to get to them too often. would you recomend just copying the output card circuit? and if I pull a signal from those solo points it won't disturb any of the other output signals?

thanks, ben

that should work fine, the op amp in of the ouput driver should buffer the signal. Is your console 4 buss?

thanks Niels - yeah, mine is the 4 buss original grandson console. I might have access to some original output cards, so maybe i will just use those to drive the direct outs. I just have to find a place to mount them. there is some space next to the other output cards, but not enough to mount 16 more. hmmm........

hey Niels or anyone - what do you think about ic's to replace the lm709 and 301's? There is the standard ne5534 that auditronics used later, and i've also heard of people using opa134's and LME49710's - any thoughts?
thanks, ben

get the cheap 5534's from Mouser.... you can try the B/B's or others, but the difference will be much smaller and maybe not better "sounding" but the change to the 5534's will be substantial
the next step up is the DOA's, that will do alot, & cost alot!

thanks Niels - by the way, I got the power supply and got it turned on. I fried a couple of resistors, still trying to sort that out. so it goes...

Realizing this post is quite old, but wondered if @plumsolly ever got the 110 console modded with direct outs.  Just picked up a 110 myself and curious to know whether it is worth it.
