Limiters used in preparing for UK broadcast

[d.f.]

Hello there.

Very long time user of Pro Tools for music production here, but I have just got a job doing work in the broadcast industry. Kinda want to keep it!

A couple of questions, if I may:

1. When preparing for UK broadcast we have to keep it all peaking below +6 PPM. I was wondering what the preferred limiters are to do this job (on the final mix bus) for the DUC community.

2. Do you ever chain up limiters to do this job? In music production I will use Real Tape saturation into a McDSP ML4000 DL1 into a Sonnox Oxford limiter on the mix bus. All these on light settings.

3. What is the largest difference allowed between lowest peak and highest peak? (does this make sense? ie: quietest bit to loudest bit).

3. When importing the omf file from the online editor I have been finding that stereo tracks come in as two separate mono tracks. Is there a way to make sure that these stereo tracks come in as stereo (is this something that the online guy needs to do?). Is there anything else I should know about importing omf files?

Many thanks in advance..


David.
