Yes, per channel. Actually, it is per logical channel (front, center, surround, back) for 7-band and then they have a 5-band for sub.
The adjustments I made were minimal. I took the curve supplied and adjusted where the dip was at least 2db for a significant portion of the band.
Settings I have used are:
Numbers are presented: Band (M80, VP150)
63 (0,0)
160 (+1,0)
400 (-1,0)
1000 (0,0)
2500 (0,+1)
6300 (-1,-1)
16000 (0,-2)
Results are: VP150 completely smooth now (a little harhness was there even for TV shows). M80 "seems" also a little bit more transparent, but the most important is that it does not sound worse!
