    Hey Guys I was wondering how many people use DRC. I've been experimenting with it lately and would like to get some other opinions. I feel that it works pretty well when you have the volume at a low level or if you just want to keep the effects and dialogue at the same level.
    I know that DRC is not suppose to alter the track but I can't help but to think I'm missing out on something. Anyway enough talk any ideas on the subject would be helpful.

    Todd,
    I assume you meant Dialogue Normalization, but what is it?

    Thanks for the response. Todd I'm not confusing the two I'm talking about DRC. I also use DRC mostly at night when my son or wife are sleeping. I just wanted to get other peoples experiences and opinions of DRC. There is a good article at hometheaterhifi.com about DRC and Dialogue Normalization if your interested.

    Are DRC and "midnight mode" one and the same?

    The idea behind Dialogue Normalization is to keep the volume level similar, as you switch between different DD sources (LD, DVD, DD broadcasts from various channels of HDTV, etc.). That way, when channel surfing, you don't get blasted by Channel 2, and can barely hear Channel 6.
    It does not affect dynamic range, simply overall volume level of all channels.

    I have the DRC turned on in my DVD player since I don't have it hooked up to a digital receiver with that feature available. From what I can tell, I don't really notice any difference with it on or off (which is a same because DRC was a feature I was really looking to use since I live in an apartment).
    I can barely watch "The MAtrix" and "The World is Not Enough"...those two movies have the dialogue recorded so low and the dynamic range so wide. I figure the dialogue "problem" I'm experience is due to two things:
    1. the fact that I have to select the 5.1 track and have it downmixed since no dedicated 2.0 track is available
    2. the DRC does work on these two titles but its effect is somewhat lost when the 5.1 track is downmixed to two.
    Can anyone vouch that they can hear compression when they have their DRC turned on in their receiver when watching either "The Matrix" or "The World is Not Enough"?
    I would really appreciate it, if other people say it works, that might get me to upgrade to a digital receiver since the DRC in-player doesn't seem to have an effect.
    Thanks
    Andy

    Hopefully someone can correct me, but I think you need to turn on DRC in the device doing the decoding. Therefore, if you're passing the digital signal from the DVD to your receiver, turning DRC on in the DVD isn't going to do anything.
    Are you sure your receiver doesn't have DRC? What model do you own? Some brands label DRC as "Midnight Mode".

    Hi Steve,
    If that's the case, then maybe that might explain why I don't hear a difference when the DRC is ON or OFF...but then why would the DVD player have such a feature then? Hmmm...well, the DVD does have a decoder to downmix the info to 2 channels.
    Currently, I'm using a DPL receiver so that's why it doesn't have "midnight mode" or compression.
