Hey guys- in doing some testing with my Onkyo, I came across an anomoly in EX decoding and wondered if I could find a couple other folks who could try an experiment on their system. Using a phase test for surround speakers (such a test signal is available on Avia, VE and even on any disc which has THX optimode). Play the phase test for surround speakers with EX processing on (make sure the processing is on!). When it goes "in phase" the sound should come out of the rear center-- but when it goes out of phase- what happens? Do you get sound from each of the rear side speakers, or do you get silence? If you could post your results and the model receiver or processor you use- that would be very helpful.
