Help! - low level distortion on tracks

Does anybody recognise this sound.
It sounds like a bit reducer
I feel the culprit must be my Motu 828!
eithor that or not great cables.
Signal chain is -
Soundelux U95
Telefunken V672
Motu 828
****ty G4

Recording onto Tracktion 24/44.1


I dont get this all the time but especialy
on really quiet parts I can often hear it
and i'm sure even when I cant it's clouding
things up.

Is it Jitter?

Time for a new AD/DA!

Thanks,
Jacob

You've definitely got a problem. I'm thinking that you're talking about the record-static-like ticking in between the counts, yeah?

It's not a problem endemic to a properly functioning 828 (at least not a mkII, which I have)... or, for that matter, any properly functioning interface. (Well, duh, hunh? heh )

I'm assuming that the MOTU is set to run off its own internal clock and has no other digital audio interfaces chained into it, yeah? Seems to me that I've heard sounds not unlike this when there were unresolved clock issues.

Thanks for replying!
Yeah, I am referring to the static that the sound (Counts) disappears into.
The Motu is the only digital piece (besides the computer).
The clock is set to Motu.
There's static on the Monitor Pot as well. (So I don't use that).
It's not under Warranty anymore.
Maybe this is one for Black Lion?
Then again, i'd really rather just invest in a doesn't Interface!
Any other ideas?

I kept thinking I'd heard that precise type of sound before so I kept racking my brain.

And I finally remembered where... but it ended up being a bit of an open end...

It wasn't a digital device at all.

It was a "pro" Superscope "broadcast quality" battery-powered over the shoulder cassette recorder, circa 1980 - and it would develop a sound just like that, over and over. I took it into the shop 3 or 4 times before I sidelined the thing. (It was a pretty interesting deck -- it was pretty much the only cassette deck I've seen that had separate record and repro heads [in the same itty bitty head shell]... I used to use it for very fast slapback echo [I mentioned they were jammed in tight, yeah?]... the static sound... well... my reverb was the spring verb from my guitar amp. Nuff said, yeah?)

When they fixed it, seems like they used to itemize it as ground strap adjustment... which I assume was the motor ground strap (which, could, after all, account for a quasi-rhythic static/ticking similar to what you have.)

Obviously, there's no motor in your 828.

BUT there are probably motors hooked up to things that are hooked electrically (signal, USB or FW data cable, whatever) to your 828.

But, really, a clock issue could cause a quasi-rhythmic ticking/static, as well.


Bottom line... I'm quasi-stumped. Make that close to completely.

But maybe this post will serve as a bump and someone with an actual clue will see this and jump in to help... heh
