Title: brickwalling / clipping...
Post by: justink on August 25, 2003, 05:41:01 PM
using a d7 / d8...  does the tape ALWAYS clip when you go "over," or is there some leeway...

like, can you hit 0db sometimes, w/out the tape clipping?

i had a horrible tape do this w/ a sony md once....

thanks!

just because an over (0db) occurs, it doesnt mean it is audible.....depends on pre/ad/mic selection.....i slam my akg 481's >into a graham patten dmic-20, and WANT to hit over, it gives you more bits and frequency response to come as close or on zero as much as possiblee..... 8)

Brickwalling and clipping are two different things...you can brickwall without going over 0db.

Brickwalling is what happens when you're running your levels too low into your deck (mic in) and making the deck's preamp overload; this typically happens below (I think) 4.5 on the knob. That's why you always want to go LINE IN and bypass the internal preamp (and still feed your deck as hot a signal as possible).

And as bean said, *audible* clipping definitely doesn't always occur on an over; on a transient over like a cymbal crash or audience clapping, you won't notice it because it's such a quick spike. When you're constantly riding into the "OVER" lights, that's when it becomes audible.

even when i run the 480/dmic-20 combo as hot as hell(ie. constant overs) its still not audible, at least not in that combo...... 8)

of course, if you can do "magical thingz with microphonez" like bean-o, you need not worry about brickwalling, clipping, eaten tapes, chatty crowds, w00k bowling... ;D

Well, could be stand and equipment, or it could be an angered taper plowing into a crowd of spun w00ks...because once one of 'em goes over, they all go over...

okay... so going over isn't so much a problem unless it's for an extended period of time??  and i want to actually hit 0db or as close as possible?  

okay,  now, new question...  is there any kind of equipment i can use that slows the eratic level movement?  because during some intense jams the levels can go from far left... to waaaaay right (0db).    what i'm asking, is there anything that can keep these jams from moving say 6 or 7 bars down to 4 or 3 bars?

thanks for the info guys, keep it coming!  :)

some sort of compressor, maybe. but you don't really want to do that unless you're recording some real soft shit.

You want this but, not to cream zero.  This eratic movement is showing that your mics are sensitive and can pay attention to detail (good resolution)...if you get creamed then your level are too high and you should turn down SLOWLY to an acceptale level.  Generally if you get your levels set at the beginning, then you should be ok and may need some fine tuning once the soundman gets it to where he wants...NOW if you run hot and they turn it up at certain parts....then you'll get creamed.
So basically keep the dynamic range in there (eratic movement) but set your levels so that they don't slam 0.  sometimes we all have to turn it down during parts of a jam where the soundman is enjoying the show and adds some more volume to it.

hope this helps

just leave a little headroom, with the music you're taping. i show up at ministry, set levels almost pounding 0 by the kick drum, and once that's dialed in i never have to worry about them again...
but the jammy stuff, with real sound men... can't tell ya much but to leave a couple dB of headroom just in case!
