I've been noticing that I have to drop the volume on my system when ever I change to HDN or HDNM from another channel on my Mits SR-HD5 box. I have to drop it as much as 12 dB when I switch to HDN(M). Any one else see this problem? Or is it just my bad hearing playing tricks on me?

I notice it too with my Sony box - on HDNET much more than HDNM. Quite annoying, especially with a 1 month old in the house. I have to be careful not to wake her when I switch to HDNET.

Mine is much louder too. Of course its supposed to be. HDNet, and HDNet Movies are usually outputted in dolby digital 5.1, and I have a dolby digital audio setup. Sound outputted via DD 5.1 is always going to be louder than non DD 5.1 (read all other stations). You'll have to ask some of the audiophiles why, cause i'm not sure why, but that is the reality of it.


Those 2 stations are the only ones i'm getting true dd 5.1 on. I'm not subscribed to HBO or Showtime, but i understand some of their movies are DD 5.1. BTW, does anyone think those HBO or Showtime HD channels are worth the money?

Bad guess. The volume on HBO and SHO HD channels when airing 5.1 material is NOT louder than the other stations on DirecTV. In fact, they are somewhat quieter and I find myself having to crank up the volume.


There goes that theory.

This isn't a new thing...HDNet audio levels have always been all over the place...lot's of variation between sources.

Crediting me with that is generous, but I cannot claim to have come up with that. I actually read that on an official FAQ regarding the Motorola DCT5100 STB, the STB used by Comcast HDTV subscribers. The question was something to the effect of, why are my DD 5.1 stations louder than my regular cable stations. The answer was something to the effect of the digital sound and analog sound are not transmitted with the same intensity, or some other related audio jargon. I'm too busy at work today to try to find that for you again.


Since you seem to accept that HDNet is possibly transmitting sound too loud, I have to assume by default you are equally willing to accept HBO and SHO are transmitting sound too quiet, explaining your phenemon. Perhaps they "overcorrected" to account for the DD 5.1 issue.

OK, going on memory seems i got it backwards. The phenemon is that sometimes DD 5.1 stations are softer than non DD 5.1. The question regarding this was posted at : http://www.cjhengineering.com/5100faq.htm


under audio heading.


The answer is here: http://mywebpages.comcast.net/miatasm/HT/dolby.htm


The thing i came away from that is, with the supposed preamp kick-in to compensate, and differences between analog and digital sound volume..... is that they are simply going to be different, depending on your settings. So if you go to HBO/SHO HD and its quieter... or HDNet and its louder, then maybe ^^^ has something to do with it. I'm not a big believer in concidences, especially with 200 some-odd channels have the same volume, and the only DD 5.1 ones are louder (or softer).

The reason for the sound being louder on HDNET and HDNET Movies is because they have the dialog normalization set on +4. When I first switch to HDNET OR HDNET Movies, my A/V receiver shows Dialog Normalization +4 Dolby Digital. The other HD channels just show Dolby Digital so I'm assuming the other HD channels such as ESPN-HD and Discovery HD have their Dialog Normalization set at 0.

ESPN-HD, and HD Discovery are not outputted in DD 5.1, HDNet is. But that normalization adjustment is interesting though. My receiver isnt fancy like that.

Welcome to the new Loudness War which replicates that which has evolved within the audio field over the past several years.


The theory is that if something is louder, it is more likely to hold your attention.


This race to loudness has ruined many new CD's including the most recent John Mayer and Rush releases. They are remarkably loud, but are plagued by distortion resulting from digital clipping.


The signal is digitally compressed so that all sounds have nearly the same volume, (typically a massively loud 0dbfs) and it appears that TV stations are following this trend created by audio mastering engineers.

Having just started getting HDN and HDNM on E* yesterday, I agree that the volume on these two channels is CONSIDERABLY higher than other channels - which is quite annoying.


Since Mark Cuban and a few other HDN people are on this forum, perhaps they can "turn it down" or explain why it has to be so much higher than other channels?

ESPN-HD is the LOUD channel here (Comcast).
