When listening to a DVD that is less than 5.1, why does the volume decrease even when put ino DDPLII?
...why does the volume decrease even when put into DDPLII?
Actually, it's DPLII, or Dolby ProLogic II, a new sound processing scheme designed the enhance two-channel sources in a surround system, like VCR tapes, tv audio. There is no particular reason one would activate DPLII when playing a DVD if one has the full surround speakers set up.
What else is going on here? What makes this seem like a "problem?"
A belated welcome to HTF, and at your leisure, please scan through the "Primer" mini-tutorials located in the HTF Basic board.

The DVD FAQ gets the details right later, but this quote is misleading. Anyone who needs to downmix their DD 5.1 soundtracks into 2.0 channels is undoubtedly using the DD decoder in their player. It's not the downmix process that compresses the dynamic range, but a non-related feature of DD on your DVD player. Most players default to "Normal" dynamic range compression, which is usually a middle-of-the-road level. This is so that you don't exceed the limited capabilities of your TV's built-in speakers. Many players have a setting that can be changed so that the decoder will apply less or no compression. Dynamic range compression can also be used on full 5.1 soundtracks, so like I said, it has nothing to do with the downmix process itself. Most DD 5.1-capable receivers that I've seen default to no compression at all.Marc Rochkind said:Quote:

We all are, which is why more information is needed. Some of us just provided a bunch of potential causes and general information, to hopefully help Doug be more specific in telling us what he's experiencing.
