attenuetters
« on: July 24, 2004, 06:06:51 PM »
I am really a beginner being that I've only had my rig with 4 recordings.  I have a set of attneutters on the line into the mixpre and can't seem to find out precisely what they are used for.  Any tips?

you're running schoeps and you have no idea what you're doing?  why does that not surprise me ;)

i might be wrong here, but as i understand it, line attenuators ramp down the dB's coming from the mics so your recording isn't overmodulated.  i think they're only used in cases where a pre-amp is not in use.  since you're using a pre-amp, i don't think you need to use the attenuators.  like i said, though, i might be wrong.  can anyone else elaborate?

As jef-o posted, attenuators reduce the signal passed through them.  Sometimes you do need them between the mic and the preamp.  If your preamp has a high minimum gain (like 20db) and the mics send a really hot signal, you can get clipping at the output of the preamp.

This happened to me with the KM184->MV100 at really loud shows (like 9:30 club Mule shows) so I used a 10db inline attenuator between the mics and preamp to drop the input signal and prevent the MV100 outputs from being over driven.

I'm curious - did you ever try running without a pre in those situations (using a phantom supply)?

No.  The MV100 was my phantom source.  I didn't have any other.

I don't think this is the problem though.  The mixPre has variable gain starting at 0 dB.

I just wanted to point out that attenuators are sometimes useful between the mic and pre.

Unless the show is painfully loud, I'd expect the MixPre to handle the CMC6 output without attenuators engaged.

And they should not be used unless needed.........
