This is not a stereo expander trick. It's demodulated left / right audio level. So in mono, it would sum together, and still be loud.
It's like driving a composite clipper harder. The same thing would happen...only in the case of Omnia.9, the audio doesn't collapse into the horriffic distortion of a typical composite clipper because of the psycho-acoustic masking applied in Leif's unique clipper. The Omnia.9 also lacks the extreme amounts of cross-channel hash typical in driving composite clippers this hard due to the same distortion management scheme.

amfmsw said:Not to throw a wet blanket on this party, but in the REAL world, not laboratories and dummy loads, how does the process perform? I mean the world of multipath, hd-analog mixing, and ESPECIALLY high frequency blending and mono mixing in weaker signal areas. If the station is loud as dickens in stereo, but drops when blending, it would sound terrible. Not all listeners live and drive in the 54 dbu contour. You've got antennas as moving targets at 65 mph. If the stereo is louder than the mono mix, it would seem pretty useless.
Now, don't get me wrong, I'm a BIG fan of the Foti products. One of the early adapters. Well engineered and bulletproof. But this has me puzzled. Looks like it's being fed through an old Fisher Space-Xpander!
