What do you guys set this to?????
Well thats what I thought but the manuals mention 'Standard', it's the way the sound engineer designed it!!!!!!
Always had mine set to standard but thats why I ask, sometimes it all sounds a little restrained!!!!!
Best set to "whatever your equipment manufacturer calls 'not at all' or 'off' or 'none' or etc....."
I've had it on, off, min, max and medium. It's way too simplistic to say you shouldn't use DRC because if you do you alter the sound in a way not intended by the director/sound engineer. You need to bare in mind this, they also intended you to listen to the sound track at REFERENCE volumes. So if you don't play at this high volume using DRC is not as such a bad idea because if the Director intended you to hear a bird tweet to your left at least you would stand some chance of hearing it.
I'd say that the volume control is a much better way of doing that,rather than something which limits dynamic range and flattens the sound.....DRC or similar is just a peak limiter.
How can you do this with volume control? Or are you saying that you should continously change the volume throughout the film? Up a bit, down a bit, its enough to drive you mad.
I see what you're getting at Jeff,but my point about the DRC is that it just flattens the dynamics.....it's job I suppose.
'Off' Sounds good to me. If I change the DRC to Off, will I have to reset up with the spl??????
Lets try again...
Without DRC the soundtracks volume is linear, so if you decrease the volume from reference levels by say 20% you are cutting off 20% off the quiet end of the sound track, much of the ambient sound will be lost. With DRC engaged you will be able the hear the enitre sound track. The choice is yours, compressed dynamic range (not compressed sound) or missing ambient sound.
I would think most film soundtrack engineers would be sensible enough to realise that most home viewers aren't going to watch movies at reference levels. They generally re-mix the original theatrical soundtrack for DVD release, and I suspect most audio engineers compensate for the lower volumes home viewers tend to use. I doubt you're missing much leaving DRC off.
(BTW, on my proc, you don't switch Dynamic Range Control to 'Off', you switch Dynamic Range to 'Max'. Somewhat confusing - don't get caught out...)
Not sure why they would do that since DRC is in the Dolby spec and if they did it would cause another problem, at reference volume ambient sound would be overblown.
drc is usefull for late-night watching.
it works by compressing the range - not cutting it off.
imagine a range (any range) from 1 to 100. With drd you can cut that range down to say 1-70. All of the information will still be there, but the range is smaller.
To put that into audio terms, it makes the loud bits not so loud. This allows you to turn the volume up which will invrease the low level sounds without affecting anything else - very usefull for dialogue for example.
#this is purly my understanding of it - feel free to correct me.
Off in the daytime, on post-11pm
DRC effects the linearity of the sound track volume. As well dampeing the really loud stuff it makes the really quiet suff louder. So if you normally listen at say -20db, with DRC you could up the volume to say -10db and by doing so the really quiet stuff will be at near reference levels and the really loud stuff won't burst you ear drums. If you want no compromise sound you should be listening at or near reference anyway.
Well, unless you dislike the idea of permanent hearing loss......
Well I watched Das boot below reference- say -15dB (MC-1 TT at 85dB) and I could make out speech, and little things like drips etc.
I guess it depends on the quality of the centre speaker, processing and poweramps. If you have any rubbish item, it's much harder to hear things. I changed from the Q75 and B&W CC6 to the 200. Much better.
Oh the MC-1 fan kicked in during the whole film (played back the dts german track) a little bit annoying, but I got used to it.
