What is LPCM? (1 Viewer)

I searched the forums back two years to try and find a thread specifically about this. I just started hearing about it in this thread. If it doesn't belong here please move it.

I was almost ready to buy a Denon 3806 until I heard that it doesn't do 7.1 in LPCM. I am not clear at all what LPCM is or does.

The 3806 is rated for 7.1. It has higher watts per channel than the 2807 and also it has 4 power supplies and better DACs as I understand.

So before I plunk down 800-1000 bucks on something that cannot produce 7.1, could some please explain what LPCM is and does.

I would appreciate it.

Linear Pulse Code Modulation. Basically, it's uncompressed digital data, not encoded in any way. CD's are LPCM at 16/44. HD DVD players decode the various formats into LPCM and send them as such over HDMI to receivers. A google search was fruitful, and these links have some good info:
