yes PLII is built into the receiver and it will give you full 5.1 channel sound, thats the nice thing about PLII, Xbox games are encoded in PLII, but even regular 2ch stuff like music etc. can be turned into full blown realistic surround sound using it. that's why i always recommend using surround receivers even for music, they have HP/LP for subs, and they have things like PLII/x/z ever since ever listened to music in PLII ive never gone back, regular two channel stereo is so boring and flat, and PLII brings out "hidden" musical details that seem to collapse in the front channels, like i never noticed Coldplays song Clocks had a synth playing in the background before. or on Slechtvalks album there is actually a female choir in the background "chanting"
