In Reply to: PCM vs DD - why DD is louder in a 2 channel system ? posted by Kenny on June 11, 2008 at 06:10:19:
Given the choice of PCM vs DD, why would you choose DD? I actually prefer 2.0 PCM from laserdisc enhanced with Pro-Logic vs DD 5.1 for movies. With the usually higher bit depth offered by Blu-ray, the choice is even clearer. For DD to sound better than PCM, there's definitely something set up incorrectly.
Check to see that the Dynamic Range Control (sometimes labeled DRC or Night Mode) is not engaged. The PCM offers a wider dynamic range compared to DD with DRC engaged and may appear to be weaker because softer passages are raised in volume when DRC is set for DD. DRC will make the average volume appear to be higher for DD because of the "squishing" that it's doing.
If you told the Blu-ray player that you only have a 2.0 system, it should down-mix all multi-channel sources to stereo: you'll obviously lose the surround experience, but still retain all of the multi-channel signal.
