I have a Sony HT-SS370 system and was wondering what the Audio DRC is for. I have it setup at Std, and the other options are "off" or "max". The manual recommends "max" but it is not very clear why.

Can anyone help as to what the best setting is? What are the differences?

Thanks.

Hard to know unless Sony tells us.
Dynamic Range Compression/Compensation?
Digital Room Correction?
Dolby something something?

Dynamic Range Compression.

It should be "off" for best results.

Even though the manual recommends using compression, I wouldn't recommend it.

Essentially, DRC keeps volume levels "stable". It's effective for those that don't want to be startled with loud "booms and bangs".

Page 61 provides info:

Therefore, we recommend
using the “DRC MAX” setting. This greatly
compresses the dynamic range and lets you view
movies late at night at low volumes.

Movies can have a very wide range of volume of sound. It can go from a whisper to big explosions and crashes. Imagine all this on a certain scale from 0-100, where 1 is the softest sound and 100 the loudest sound. On a system that doesn't use some form of DRC, when you set the volume so you can hear the softest sounds, the loudest sound can be really really loud. Great if you want the full impact of the audio portion of the presentation. But not so great if you're trying to be considerate to other dwellers in or adjacent to your residence. But if you dial it back so that the loud stuff isn't too loud for your situation, you'll no longer be able to hear the soft stuff. So that's where DRC comes in: It compresses that range so that the loud stuff isn't that loud. And that way you can leave the volume up so you can still hear the soft stuff, but now the loud stuff plays at a much lower level so that you don't wake up your neighbors. Obviously for the "best" experience, you should leave DRC set to "off", but for practical reasons (like late night viewing) you may want to turn it on.

DRC only works with Dolby sources. Also, it is applied by the decoder. So, if you are bitstreaming to your AVR for decoding, then the setting in the player doesn't matter. The one in the receiver would be used instead. Or, if you are decoding in the player, then the DRC setting in the receiver doesn't matter.

This is really helpful since I am streaming LPCM from the PS3 and have not really experience a big difference from the DRC setting, which sucks cause I really would like some compression. I am going crazy trying to keep the volume tolerable at night. I wish the PS3 had the option to compress.

I'm sure it does.

Yep, you are right... it does... Just turned the DRC on the PS3 and fixed my problems. As long as the track is Dolby TruHD, or Dolby in general. Thanks!
