    i have a sony str de-995 do any of you out there have this receiver and what do you think of it. I had an Onkyo 801 $300 more than sony but its circuitry kept protecting and turning off. I like the sony it sounds great. 6.1 sound hard to get, i guess not too many movies coded for it. What drives me crazy is my display always reads dolby digital 3/2.1 does that mean my receiver is reading 5.1 or not! it is driving me crazy. It sounds like my surrouds are on why does it not say 5.1 :nono2:

    Hmmmm

    Just a guess but I bet it is giving you a detailed breakdown on which speakers are currently active with this sound source. 3 fronts, 2 rears, 1 subwoofer.

    Sounds like 5.1 to me.

    I think ibglowin is right, it's just the way Sony is telling you 5.1. To check it out, you could try playing a DVD and setting the sound in the DVD menu to two channel stereo, it'll probably read 2/0 on the receiver display.

    And remember with Sony receivers, always look for the "Blue Light" special. That for sure means your getting true 5.1 DD from the source.

    Hi all,

    3/2.1 is Sony's way of saying 5.1. From a post from Agoraquest.com (a great resource for all things Sony):

    "1. First, some nomenclature. There are several types of digital signals:
    - PCM usually refers to a 2-channel signal that is used on CD. It is also the signal that is output from a DVD player IF you haven't told it to output DD or DTS.
    - DD & DTS can be up to 6.1 channels (Sony and Panasonic display them as "3/3.1" - more on this). But they can be fewer than that. They can be 2/0.0, 3/2.0, 3/2.1, etc. For example, most DVD has at least two tracks. A DD 5.1 (3/2.1) and a DD 2.0 (2/0.0)
    - The first number is "3/2.1" refers to the number of front channels. Second is surround, or rear channels. The ".1" referes to the subwoofer. "3/2.1" is the same as "5.1", and "2/0.0" is the same as "2.0"."

    The entire post with a lot more information can be seen here (it's about the 10th post down in the forum by "rkkwan"):
