How well does Dolby Pro Logic work with newer surround formats?

Your Dolby Pro Logic receiver cannot process any of the newer formats, either Pro Logic II or Dolby Digital . Basically because your format is analog technology and both of the newer formats are digital formats. You are not missing much as far as sound goes though, you don't get the real deep bass sound effects, and your rear or surround speakers are playing in mono not stereo. You also don't get the good separation in the rear speakers. If you can afford it and do watch a lot of DVDs , I would suggest that you upgrade to the newer formats.

The reciever will work with the new formats but it wont allow you to take full advantage of the quality of the new formats.Pro Logic just means all the sounds will be sent out at the same time where in a newer reciever you would hear the seperation of the sounds. For example a plane flying acroos the screen-it may start at the rt front then the center then front left to back speakers-much like the movie theater.So to truly emjoy what the new movies offer a newer reciever would be wise but not required.

The short answer is no, your old Pro Logic receiver is not compatible with any of the new found formats. Your receiver is capable of receiving basically two types of sound formats, Pro Logic and Stereo. If you are interested in taking advantage of new formats you will need to upgrade your receiver. Considering how affordable home theater equipment has become over the last several years now is a great time to buy. Go to Best Buy or whatever electronics retailer you prefer and find a receiver in your price range. $500 goes a long ways these days to getting a real nice receiver with many of the extras.

It will work fine with sources marked "Pro Logic II" which is technically the same system. It won't decode "Dolby Digital" signals at all, BUT any Digital source (such as a DVD player) will also include stereo outputs which deliver a Dolby Surround-compatible signal that will, again, work fine with your Dolby Surround receiver. Dolby Digital (and other full-digital sources such as DTS) do have some advantages over Dolby Surround -- in particular the left and right rear speaker sounds can be different (they are the same in Dolby Surround) and can have full-range audio bandwidth (this is limited in Dolby Surround). But all these technologies are downward-compatible with Dolby Surround as outlined above, and will provide sound at least as good as what you get with your Dolby Surround sources. So if you are happy with your Dolby setup, no worries, just use the stereo outputs from any device you choose. If you want more dramatic, gee-whiz surround, you can upgrade anytime. Good luck.
