Behringer ADA8000 modifications..
- Thread starter gyraf
- Start date
Help Support GroupDIY Audio Forum:
I listen to my stock ada8000 up against my lavry, my avocet and itself backto back, itself through the avocet's analog in. And today again tests with a peq1a and the ssl hooked up through it.
It's just as hard to tell it apart from the avocet as is the lavry.
(Now, I of course don't clock it internally, ever, I could tell that, but it was still not that far off, so I don't know
if that's making the big diff, all the time, but I'm not sure fudging with the highend
or the opamp is going to gain you something you're not taking away
in the bottom.)
And the top vs bottom, is the biggest difference always between cranesong stuff and anything else. I seem to noice that also kind of seems like ne5532 vs opa2134 as well. But, for instance, I put in dual ad797 (think it's 797,) in my ssl because I could most certainly tell of
a width issue in stereo field.
But, Unless my adam's and my ears are fooling me, and I just swtiched rooms again and the story is the same. That like ada8000, doesn't suck so bad I thought it would, so i kept it.. I still continue to look for a reason
to mod as you guys are doing, but alas, it's just doesn't sound that far
off with program material anyway to warrant it, I couldn't imagine
where you'd gain something.

I was wondering about that... I have an EMU 1212 card and I was wondering if it would be better to slave the Behringer to the ADAT input, but I was reading that lightpipe is not so good so good for jitter? Or are you saying the Behringer clock is that bad that ?
Jakob - I downloaded the trial version only, but it crashes randomly... not just when I run out of time. I'm a little scared to purchase a license if it doesn't work...
I'm gonna give that rightmark analyzer a shot, and let you guys know my results.

Well, adat is the worst for jitter, it's clock is better, but
the lynx card I have has a summing algorthim and the lavry is a palatible clock as well.
I can't do a test on the lavry till next week but I compared the ada800 and my da7. very interesting results. the da7 is -.5 db from 10k smile down and the ada800 +.5 from 10k smile up. ada8000 was notably noisier. but so far below sick it's sick.
that tool is hand indeed.

Ok, I did these compares.
out to in, lavry da 4496 to it's ad. Of course it won, da7 in the middle,
no suprise ada8k on the "bottom".
But, again, I don't know, the numbers all still kick rear, and the curve
the ada8k has makes up for it's lack in perfection is what my ears tell me.
Again, hearing them is a little different than this test, but I just loved this tool when I saw it.
it makes me which I still had my hd24 sitting around, I always put it right in the middle with the da7. but I never thought it sounded as good.

Thanks Cwatkins,
The only spec that worries me a bit is the "THD + Noise (at -3 dB FS)" - that indicates a bit more distortion than needed. Would be interesting to see how it behaves with MC33079's or similar low-distortion opamps..
Are these specs btw for a modified or a stock channel? How is the A/D gain set?

Wat makes the difference in 'sound' between those convertors? I would say the Lavry could sound a bit duller in the higher range, but can you actually hear the difference between them on THD or ID or ... ?
It's stock, I've been watching the thread, to look for a simple mod.. But I can't hear why you would..
I set the a/d gain as close to -1.0 like it said as possible, in fact they all landed around -1.3, I think the lavry had -1.3, -1.4 which might explain it's stereo weirdness.

hi dug,
would be great if you could run the same rightmark test in both modified and unmodded channels for comparison
cwatkins,
could you make the ada8k test but using the internal clock for comparing vs lavry wordclock slave?
Thanks!

Hmm, external clocking is a pain, it's fixed now (cubase3 had it broke, so I was kind of setup that way on purpose, but my lynx cable is custom and it doesn't have a clock in). Let me see if there is a way to do it with my lucid through aes without skewing the results.
BTW.. I did messup clocking on purpose.. you get horrible results,
but certainly something that might make you THINK you had it hooked up right.

Yup.
So theoretically, I should do all the tests over through the same A/D.
And then, everyonebody just uses their ears and that's where the grey comes in.
The benchmark is mighty fine, tightest low end I've heard in a D/A, ever.
The only reason I did not keep it, is because for 1500$ more, i got all the
features of the avocet.
But another thing that I like to consider about testing units, especially
something like the ada8000, is ok, look, manufacturure, you sure as heck had better have tested your own a/d with your d/a, especially when it's attached in the same box, and if you can't make the idiot thing flat/work well in and out, then what in the heck are you thinking?
That is what I do not understand. especially since I will probably only use the ada8k for stubs or analog processing.
I can see not being flat with somebody else, but with your own d/a and a/d..

I finally got around to testing out my Behringer:
http://www.mikerelay.com/test/7024.htm
http://www.mikerelay.com/test/m33079.htm
http://www.mikerelay.com/test/Comparison.htm
My setup is this: I have a EMU 1212m card. I ran the output of the analyzer out of the card and into the input of the Behringer. I used the ADAT lightpipe output into the EMU and set that as the return to the analyzer. I did this because I swapped out only one of the opamps.
I set the ADA8000 to 44.1 and used it as the master clock.
I'll post some pictures. I made the opamp "swappable." :thumb:

good news mike,
The way you do it is showing the diff only for the AD part for the B, but there is a improvement. Don`t know about the quality for the EMU DA so I`m anxious to see the full B unit comparison
Also looking for your "swappable" feature!
Thanks,
Synthi

yes roosi I forgot that, test in 24bit is the way for testing the specs at full.

This seems a bit strange to me? you couldn't tell them apart, the Lavry, Avocet and ada8000?
I could emagine that changing opamps and maybe tweak the filter a little(or just remove it) would make a would of differnce in the ada8000.
Best Regards
