I just purchased a new pioneer vsx515 receiver. There is a Dynamic Range Control option. I can either have it OFF, MID or MAX. Now what I would like to know is what does dynamic range control do?

Also my DVD player has a Dynamic Compression option. Should I have this option selected to ON (selects dynamic compression) or OFF (selects standard range). It's hooked up to the receiver via digital coax and I have it selected to bitsteam.

One more thing, while I was watching Blackhawk Down in DTS the receiver overloaded twice during loud scenes. I had the volume at -45dB. When I switched to Dolby 5.1 for the rest of the movie it didn't overload at all. Also while watching Aeon Flux in Dolby 5.1 it didn't overload either, same volume. Any idea as to why? Oh, I'm running Athena Micra 6's.

Thank you.

This control is so that you can play the system at nite at lower volumes and still get the full dynamic range.. Normal position should be OFF..

Receiver should not shut down at such low volumes..
Suggest that you check your speaker wires make sure no little strand is shorted at either end...

I own a VSX 515 as well and I leave it set at off. I also so set the DVD player to off. I don't beleive that it is right to force so much into the receiver and the intention of this feature was for a straight connection to the television to enhance the "littlte" viewing experience.

By the way how did you get your recever to work in Bitstream ? When I set mine to bistream all the processing just seems not to be indicated any more so I just leave it in PCM. Lend me your info. please ?

Thanks for the info guys.

Wildcard26, I''m not sure what you mean. I have my DVD player set to bitstream and the receiver reads it as digital. Am I missing something?

It reads it as a digital input but doesn't use the Dolby digital mode that it would lock into in Standard mode processing.

Bitstream "on" or "enabled" in your DVD player is the proper setting to enable your receiver to decode DTS or DD.

DTS, is 3dB louder than Dolby perhaps this is why the volume level changed dramatically. See www.dtsonline.com to confirm this.

Actually just the opposite. Dynamic Range Control is to reduce the encoded Dynamic range so you can still hear the dialog fine, but the loud surround sounds and LFEs will be quieter. This would usually be used at night when you did not want to disturb others or some similar situation. I believe it is only available for DD encoded material.

Yeah, I did that and it just seems to not display Dolby Digital in the display.

Now, I haven't got the sub in here yet but could someone with this receiver, or knowledge about this help me understand the settings here. Does the LFEATT 10 help protect my sub from being fried at low frequencies ?. Here is the quote from the Ownwer's Manual for VSX 515.

LFE Attenuator Setup

• Default setting: ATT 0 dB

Some Dolby Digital and DTS audio sources include ultra-low bass tones. Set the LFE attenuator as necessary to prevent the ultralow bass tones from distorting the sound from the speakers.

1 Select LFE ATT from the OTHER setup menu.
2 Use (cursor up/down) to choose the setting that you want.

• LFEAT 0 – No limiting (recommended setting)
• LFEAT 10 – 10dB of limiting
• LFEAT ** – No sound from LFE channel
