I installed Audyssey Pro in an Integra DTR-70.1 and played with the DSX settings. Although the AVR is a 9.2, I'm not able to use the surround back speakers with "Audyssey DSX". I looked at your examples (http://www.audyssey.com/technology/dsx.html) but I'm not able to get these configurations. I have 2 front, 2 front-wide, 2 front-high, 2 surround, 2 surround-back, center and subwoofer. Valid combinations could be: SB+FW or SB+FH or FW+FH. With PLIIx (and some other sound modi)I do get the SB channels, but with "Audyssey DSX" the SB channels are not used: I only can switch between FW and FH.
Am I missing something here?
