Unfortunately we have BS-412 Multiplex Power regulations here in Sweden and this hasn't been a problem until now when suddenly the authority is measuring stations all over the country and ordering stations to comply with current regulations :-[
At the moment we're using the old BBP and as a quick fix I've turned down the overall MPX-level with about 6-7 dB and turned up pilot + rds to compensate. This doesn't give exact MPX-power control so we have to stay a bit below 0 dBr to allow headroom for "loud" tracks.
I've set up a new machine and running the new BreakawayOne with the BS-412 presets, but the volume goes up and down quite a bit which is really annoying, especially during dance/EMD-music.
Can anyone recommend any settings for BS-412 MPX regulations? I've tried to tweak the peak limiter drive and power limiter drive but it doesn't give me what I want :-\
Getting BS.412 consistent is a combination of a few things.
The first is getting a consistency to the power, and often that means needing to have a consistent bass sound at the right loudness. If the bass is too loud, that'll tend to make the power vary mostly depending on the bandwidth and deepness of the bass even if it sounds consistent overall, vs songs with not much bass/deepness. If you want a decently louder than "flat" bass sound on air, you'll just have to settle for being more quiet elsewhere.
The second is to not lean heavily on the BS.412 limiting. If you do, you'll find out why judging loudness from the dBr measurement is not accurate at all, and why I remind people about it fairly often when I see people equating dBr and loudness. Getting a more consistent power measurement, while not compromising your loudness consistency, will allow you to be close to the peak dBr more of the time, and be louder on air, and not run into the dBr limiting effecting your loudness consistency.
What market/s is your station in?
Thank you for taking time and giving me some more insight in the complexity of BS.412.
I’m in a small market with 4 public service stations (3 kW), 2 commercial stations (3 kW) and 2 community stations (300 W). I'm managing one of the stations broadcasting with a community license.
I can only compare our sound to the public service stations since the others are still at 7-8 dBr.
I used a pretty standard “Plutonium” preset (with some Bass-EFX, Clunk and Slam) on BPP and we were really happy with it. I can’t get the same punch and clarity using the same preset on BreakawayOne with 412 enabled. At the moment I’m trying the “Reference Hot 412”, it’s a little bit to light processed, but it has a similar bass punch and clarity as our public service stations. And with this preset I’m able to at least compete with public service in loudness, but with the power limiting problem as I mentioned before. And if I turn down the peak/power limiter drive our loudness is lower than public service :'(
After some more late night testing I found out that "LEIFF 412" gives a pretty consistent loudness level with less audible level adjustments due to power control.
I can really recommend the Omnia.9 manual for anyone else reading this and using BreakawayOne. Many of BAO functions is present there and have good explanations for what the do. It's available at The Telos Alliance web page.
