Help Surround decoding formats.

I'm in the mkt for a low end 7.1 channel receiver and
I want to make sure it has all the decoding formats
that are important to me. First of all, can I assume that
all of the receivers will matrix 5.1 ( which most titles
are ) to 7.1? Also, what is 5.1 24-96, and circle 6.1.
It seems I know more than most of the sales people
helping me. Any help would be much appreciated.
Circle in my opinion means all channels driven for 2 channel stereo signals, 24/96, and others like "discreet" and "Matrix" are DTS signals and are mostly automatic and disc dependent. As far as I know any 6.1 and 7.1 will indeed matrix 5.1 audio. I would look into a reciever with equall power output and be careful of those that try to claim that...some can be mis-leading. make sure it has all the features you need, and not too many you dont..focus on what is important (cross-over adjustability and such)
Dolby Pro Logic IIx is the latest/greatest thing. Sometimes its just called Dolby IIx, but it will take any 2 channel or 5.1 and and create a 7.1 sound field.

HTH, Dave

I'm no expert on all of the different surround formats (many of which are just marketing gimmicks!), but I do have a recommendation for a great inexpensive HT receiver.

The Pioneer VSX-1014TK or VSX-1015TK are truely excellent considering their street price of about $350 or less. I own the 1014TK and I really like it. It is THX Select certified if that is important to you. The build quality is excellent (it is supposedly nearly identical to one of the ELITE models) and it sounds great for the price.

I've owned about 10 different HT receivers over the last 5 years, ranging in price from about $250 to $2800. The Pioneer VSX-1014TK is not the absolute best that I've owned, but I do feel that it is easily the best value.

The 1015TK adds THX-Select-2 (supposedly the World's first receiver to offer this new THX cert) and it has DPL-IIx. Like the 1014TK, it also has an automatic surround setup feature called MCACC which uses a microphone to calibrate the receiver/speakers for correct setup, in your room!

These 2 Pioneers are seriously good receivers and probably meet all of the needs of 99+% of the HT buying public. That last one percent can go out and spend hundred (or thousands) of dollars more to get the last little bit of extra performance.


Whatever you choose, I highly recommend DPLIIx and/or Logic7 to be able to enjoy 7.1 listening. Most new receivers seem to now offer DPLIIx, and I believe the newer HK receivers offer full functionality Logic7 (can be applied to all sources. Older HKs could only apply Logic7 to 2.0 sources).

From my own listening, once you experience a properly set up 7.1 system, you won't be satisfied with 5.1.

I don't recommend DPLII as it only supports 5.1, not 7.1. And I don't recommend a 6.1 speaker system. If you are going to expand beyond 5.1, go to 7.1.
