Line mixer (active)

[Freq Band]

I am trying to find dave's schemo, linked on the first page of this thread.

Dudes and dudettes....GroupDIY is the most confusing file site I've ever encountered. Chalk me up as another mystified diy'er trying to find something on that site. It is well-intentioned, but in need of updating.
Sorry if this strayed off topic. I am gearing up to build this mixer.

FWIW, I recently signed up for this, looks like a good possible alternative. (files can be made private/invite only, too.)

SO. Can anyone tell me how to find dave's Op Amp Mixer schemo's ??

Please?

Any news on the master section from this project?

 

[capnspoony]

I just used what dave had posted from the start

If you lost it I could post it here

I think I've all scmeme's posted here but thanks anyway.

I thought Dave was going to redraw the master section ..

after reading through the whole thread and spending some time staring at the schem...it seems pretty perfect for what i would like for mixing from my daw. 16 line channels (no eqs) some auxes, a stereo bus and its a simple design!

im curious about adding more auxes (6 or even 8 if possible). I know it was mentioned early in the thread that this is dependent on what the buffer opamp can drive.

will I have a problem driving 4 auxes post? should i buffer them with another ic first?

You'll be pushing it for a tl07x (4 10K pots in parallel make 2k5, getting into the territory where the tl0's feel over burdened), but the 5534 will be fine.

if im following the math correctly thats 10k/4 = 2k5 and there for 8 auxes would be 10k/8 = 1k25

it was also mentioned earlier that a 990 is rated down to 75ohms. my questions is, can this 8 bus setup work if designed with a 990?

This was never meant to be a "project", just an idea that I never had time to go back and fine-tune.

I would have to dig out the schematic and look just to remember what the hell I drew :roll:

yeah i can totally understand. i read through the whole thread and realized it wasnt totally fleshed out. but it's a great idea!! seemed simple enough even for me.

Any updates on this? I lost the original PDF and I wanted to start building.

 

[therecordingart]

bump...

I'm interested in this and the pdf is nowhere to be found.

Bump! Would anyone mind reposting NYD's shema?  Improved or no, I'd like to look at it for educational purposes.

Thanks!
