Does this technique make sense?
« on: January 19, 2007, 11:48:45 AM »

HI,
I have a client who also masters with a "top" brazilian mastering engineer in Brazil. (When budget is fine...)

He commented that whenever he leaves Pro Tools HD to go into outboard analog gear ( Manley, Crane) he always passes the audio into a plugin (L2 probably) because analog systems do not respond properly to quick peaks.

Am I missing something in this? As far as I know you should only peak limit at the very last stage so as to not lose transparency and in a certain way, avoid  reducing the dynamic range (true full wordlenght) drastically beforehand.

Thanks for any explanations of yours in advance.

In theory, digital has no slew related limitations, but the fact is we work within bandwidth limited systems, and even 192k sample rates do not exceed the slew rate of any decent analog gear.

I don't know exactly what he's trying to do, but what he's telling you is wrong...

Just fancy gear, in fact: Manleys, Manleys, Manleys, Crane, etc.

Uh...except tape.  Ever printed a square wave to tape?  

I don't think you're insulting digital here, but there are plenty of great sounding analog boxes that have absolutely no response above 50, 60, 70k.  100k of bandwith is what every tech I've ever dealt with tries to maintain through the system.  


I had a very interesting interchange with Dick Pierce on the ProAudio list about this a few years ago... we were discussing whether analog had "infinite" resolution.

I'll see if I can find his comments in the archive.



I, too, suspect gain staging as the reason for needing a plug in front of an analog chain... especially when dealing with the levels of a contempoary master.  An analog compressor or eq may or may not like to be hit with an average level of +16 or more depending on the converter.  If you like your VU meters...

Read what I wrote in context with the original post - the guys says that he processes with a digital limiter because the analog gear can't 'keep up' with the digital signal. Not bashing digital, just saying that in this context, analog is superior...

Interesting.. some other MEs ( at other room) ended revealing they may also put the L2 before signal reaches the high end analog gear . Reason? catch up some peaks..

I guarantee he doesn't gain stage his DIGITAL chain properly!


This entire concept is ridiculous if one is operating at proper levels.

I NEVER would put an L2 on output when moving to the analogue chain.

where would you put it? (...some decorum, please, gentlemen)

don bartley strapped it across the mix during the mastering, which got me a little concerned, so i kept an eye at it, but, to be honest, it didn't seem to be doing much (the tubetech multiband seemed to get more use)

Ditto.

I have tried the L2, TC 6000 Brickwall and even the Pendulum PL-2 (analog) for the purpose of trying to tame some out of control peaks before my analog chain but none of them helped without degrading the sound! In the end, working hard on gain staging plus drawing down a few peaks, if necessary, works the best.

Andy, I also agree with you and Brad. Avoiding as much degradation as possible at such early processing with the crusher (L2 or similar).

Right on.

My point was that he might be distorting the crap out of his analog chain (with too hot levels & the peaks), and he thinks smashing the crap out first helps in that - take the peaks out and lower the level and your vari-moo is happy. Or maybe he likes the sound of the chain when it's distorting a little in the RMS area but of course, you're already in the crap land with normally dynamical material.

But only he knows for sure..
