Pro Logic rear left and right channels are in MONO and the frequency responce is limited to only 8kHz. While Pro Logic II the rear channels are in stereo (for lack of a better word) and are also full range (to 20kHz). Sounds better to me.
What is Pro Logic 2?
Can someone explain what Pro Logic 2 is for an HT newbie? Why is it desirable to have? Is it better than Dolby Digital 5.1? You probably can tell that I am an HT newbie. I have an old Denon 5.1 receiver. I am thinking about upgrade to a new processor or receiver with the new Pro Loggic II (since that what friends are tellling me), but Idont know what it is or if it is good to get? Thanks
