D100/M1 brickwalling problem
« on: March 15, 2004, 06:34:09 AM »
I'm under the impression that my recording shouldn't look like this.
Very disappointing...

AT853Rx > mp-2 > m1

not sure what could be going wrong.  Armen got the same thing at Ras Michael with the mp-2, though not as bad, which isolates the mp-2 as the culprit.  Thoughts?

thanx

No clue what could be happening but that is a weird looking wave. :-\

I'm told it is "brickwalling," but why/how is it happening with my mp-2?

I don't understand why it would be brickwalling.   To me it looks like some kind of power issue because the  wave form is cycleing.  

I'm sure someone more qualified will be along shortly to help out! :)

Could be brickwalling because the top of the waveform is squared off (clipping) but the other noise is weird.  I'd look at power/cabling first.

SPL did not exceed the rating of the microphone, did it?  Too loud an input signal would saturate the front end of the mic, and cause brickwalling at that stage (hence attenuators on mics).

Does this happen consistantly, or was this a one time, non-duplicatable, freak occurance Schwilly (and did you wash those SHEETS yet?)

but the other noise is weird

what other noise?

This was during metallica tonight (last night).

Happened consistantly throughout the show.

Mics powered 48V.  Never had a problem in the past. (well, I haven't)

the bass might be overloading the mics, but I don't think that is the problem because this happened last week with different mics at a much more mellow show.

Anyone heard of an mp-2 brickwalling?

I just need some sleep

might be the transformers on the input,dying..and can not handle as much input signal any longer.

I don't know, man - something is certainly fucked.
For Ras Michael, I ran DPA 4061s > modMPS-6010 (no HPF) > MP-2 (HPF @ "80") > M1 and there was definitely some brickwalling action, just like the HPF wasn't working and there was too much low end for the MP-2 to handle. I thought it'd be an isolated incident... but now, I'm starting to think that something might be wrong with the MP-2. But what?
asdfjkjkldfakldfjasldkfjlsdfkj is right.

I had to deal with this shit all the time with my 4061s and AD-20, sometimes even after I padded the inputs... this has to be fixable!

I can't read the pic well enough, but what is the frequency of the largest waveform (the one all the others are riding on)?
