The 9200 can create that kind of asymmetry of the pos peak control is turned up that high and the transmitter can reproduce it.

Two questions for the group:

I have an Orban 9200 at the studio ahead of a Marti STL-10 mono system. 
The xmtr hits positive peaks of 140% regularly while negative is tight 
at 100% all the time.  Could the STL be messing with the asymetry as I 
don't think the 9200 would create that kind of difference. 
Interestingly, it's not particularly loud over the air.

I'm also wondering if it would make sense to cut the audio bandwidth in 
half from the 9200, say 4.5kHZ instead of 9-ish to stop wasting 
modulation on frequencies that almost no receivers except the modulation 
monitor can pass?

Remember, I'm an FM guy :)
