Denon 1920 LPCM

[Alex2507]

There is an ON/OFF setting for LPCM and 3 years later I'm still not sure what it does. I noticed where member Lordoftherings mentioned that that didn't go out over HDMI. Can somebody give me a rundown on what it is and how it gets used and what it's good for?

I like the player a lot but I need 3 foreigners with 7 degrees to translate that manual from English to American.

I honestly don't think that my English is that good. I'll give this a try, though.

Your LPCM setting ("ON" or "OFF") seems like one of the options on my Panasonic DVD player. I can select the PCM sampling frequency for a digital audio output, but I have more options - "Up to 48 kHz", "Up to 96 kHz", and "Up to 192 kHz". I believe that yours offers you the ability to set the frequency limit at 48 kHz (set it to "ON") or let it output at higher (set it to "OFF"). I'm not sure what that higher value is, as the option is only available for sources that are over 96 kHz - which makes no sense to me, because I'd think that it would be available for sources that are over 48 kHz as that seems to be the limit that it sets with that option.

Anyway, I believe that it's because most receiver before some date (I forget...around 2000) couldn't handle sampling frequencies above 48 kHz, then they improved to 96 kHz, then they improved more to 192 kHz. So, if you have an older receiver that can't handle above 48 kHz, and you send it 96 kHz, I'm assuming that you'll just enjoy the beautiful sounds of silence (but I don't know for sure).

Where's MDS? He'd know this.

Geese, Alex. I was late to work because I researched that for you, and not even a response. I'm hurt. Deeply.

Okay, not really. I'm just bored and decided to give you a hard time.

LPCM Select= OFF

Hi Alex,
In the 1920 manual, at page 26 "Audio Setting", LPCM SELECT should be normaly set to "OFF", which means the digital output (coax. or opt.) will be output at 96khz (or 88.2khz); if your receiver is fairly new enough (8-9 years or younger), which I'm sure it is.
Also, this function is not effective for the HDMI output, nothing to do with it.
If you have a newer receiver with HDMI version 1.1 or later, you can play multichannel Dvd-Audio (if not copy-protected) from your Denon DVD-1920 HDMI output, but not SACD, even 2-channel. For SACD, you'll have to use the 5.1 analog output of your 1920.
Hopefully that helps, happy listening.

I set it to back to off based on what I just read but didn't fully understand.
I'll get it figured out later like lots of other stuff.
Thank you and welcome to AH. Check your User CP.

Take your time to read the very short section of your manual

If you set it to "on", you will down-rez to 48khz, which is a lower resolution. So, by setting to "off", you have access to a higher and better resolution. Again, check your manual, take the time to understand what they are saying, and it will eventually come to you. Anyway, it's not that much important, because it's only for few discs, mainly Dvd-Audio or the older format encoded at 24-bit/96khz, very few.
By the way, which receiver or pre/pro are you using? Thanks for welcoming me. And sorry, but what is my User CP?

Toward the top of this or any other page is a blue task bar or menu bar type of thing. On the far left is a button for User Control Panel (C P). When you click on it one of the things that shows up is 'Latest Reputation Received'. The ordinary thanked posts are worth 3 points and when I clicked on the 'scales' on the top right corner of your post it left a ton of points and allowed me to leave a comment. You can do searches for 'reputation', scales, points, chicklet to see how it all works.

I use an Harman Kardon AVR 430 but am trying to get into the Yammy 663.

Gotta love Denon manuals.

Set to ON when outputting 48 kHz (or 44.1 kHz).
The way that is worded implies that you should set it to ON when playing a disc recorded at 48 kHz (DVD) or 44.1 kHz (CD) but there is no reason to do that unless you are sending the audio to a receiver that only has 48 kHz DACS.

They really should have just said to set it to ON if your receiver only supports 48 kHz or lower sampling frequencies. If this were set to ON and you were playing something recorded at 96 kHz, it would be downsampled to 48 kHz so the receiver could recognize it.

This function is available only available on digital outputting of a disc recorded in over 96 kHz (or 88.2 kHz).
This 'function' is simply passing that audio that has a sampling frequency of 96 kHz or greater with the caveat mentioned in the next bullet point.

Sounds of the DVD-Audio which exceed 96 kHz (or 88.2 kHz) will be output as 96 kHz (or 88.2 kHz) even if LPCM SELECT is set to off.
This is the crux of it all. The player can read 96 kHz or greater discs but if the sampling frequency is greater than 96 kHz, it will be downsampled to 96 kHz (which kind of defeats the purpose of hi-res audio formats, no?)

In other words, this player is the same as any other DVD/Universal player:

- If you set it ON, it will downsample anything over 48 kHz to 48 kHz. If it is already lower than 48 kHz, which presumably is why they say '(or 44.1 kHz)', it will remain 44.1 kHz.

- If you set it to OFF, it will pass anything up to and including 96 kHz but anything greater than 96 kHz will be downsampled to 96 kHz.

My brain hurts after trying to deciper that manual. I'm going back to something less taxing...like the code I need to finish today.

Ya,I know, this is part of Denon's jargon language, perhaps translated word for word from the Japanese language.
Anyway, you seems that you were able to decipher. That, deserves some congratulations.

The take away message is to leave it set to the off position. I will make an effort to understand the 'why' more fully but later.

This player while being the very nicest 'present' my g/f ever got for me has been a source of befuddlement from day one. Denon's explanation of the 1920's up-scaling and de-interlacing over HDMI and component features and how the features are affected by a display's HDCP compatibility took me years (2) to unravel. Granted, I knew nothing when I got the player but for the love of Pete, they could have done a better job ... but I love the player.

The cruel reality is that now that I am just getting the hang of it, it's time for Blu ray. It's kind of like finally getting analog audio and video interconnects all figured out and The Basteria go right to the various HDMI versions.

It's a sin.
