can anyone here tell me the best setting on the PS3 to play audio cd's from all 5.1 or 7.1 speakers on the 705, the way i have it set now it only plays from the 2 front left and right speakers. Thanks.

I encourage everybody in the 705 thread who wants to understand Audyssey better to wander over there and read through some of the posts.

Related to that, in the manual it says when running the Audyssey setup if ANY of the speakers are 4 ohms or greater and less than 6 ohms you should run Audyssey with the setup at 4 ohms.

Does this mean I should run Audyssey at 4 ohms and then set the speakers to 6 after the fact? Or, if I'm going to leave the speakers set at 6, I should run Audyssey set at 6?

thanks!

In most cases, the 7.1 modes like PLIIx is audible (in my surround back) at all times but the other 7.1 modes are audible (in my surround back) sometimes during the movie playback.

Is this how the different modes are supposed to behave?

As i understand it, All Channel Stereo sends the same signal to all speakers (so the SL/SBL and SR/SBR would be playing the exact same track as the main L and R speakers. When listening to other surroud modes, you are only getting surround sound like cups clinking in a cafe, background conversations, helicopter flying past type stuff, as appropriate for the movie. If the source has discrete channels for the surround then you hear exactly what was intended... if you are using PLII and PLIIx etc then it attempts to "create" the surround info which means that some parts of the main channels are going to the surrounds, depending on how it calculates what it thinks should go there. The various listening modes that do this "creation" would differ in their alogrithms and how they decide what to play out of the surround speakers

Does this mean it is processed as Dolby 5.1? I am under the impression the Onkyo doesn't auto-detect which type of signal it is processing.

What is the best setting for HD DVD bitstreaming players as far as great sound and matrixing is concerned?

I realize this may be moot since it seems that most HD-DVD / Blu-Ray are using DTS-HD MA and skipping DTS-HD. Just curious though. Thanks.

My front speakers are Polk RT800 tower speakers and the center is a Polk CS350. They are about nine years old and were good speakers when I bought them. I am using Polk RM 101 speakers for the surround sound. The powered sub is a Velodyne. I'm trying to get the best possible sound that I can out of this system. Can you give me any tips or hints on improving on Audyssey on the other speaker settings? I'm not very impressed with Audyssey, or maybe I don't know what I'm doing. Thanks.

There is some great info there and it certainly shows that Jeremy Anderson has been spot on with the advice he has been giving to everyone here in the 705 thread, regarding Audyssey It's interesting to read that it doesnt actually attempt to set the channel trims to reference level (due to too much variance in the shipped microphone) but instead aims to set the relative trims so that all speakers are at the same level. And as Jeremy always points out, people who manually change the sub distance setting dont understand that it isnt a measure of physical distance and due to the subs crossover delays etc, you actually WANT the audyssey calculated distance!

Originally Posted by Jeremy Anderson

Glad kplex linked to this. Even I didn't know it wasn't trying to set channel trims to a set point. At least we know anecdotally that it tends to set things 2-3dB below reference, but it's good to know that this wasn't particularly by design.

As for the subwoofer delay thing, there's a caveat: If you're seeing a detected distance that is wildly off from physical distance, like maybe more than 6 feet, there are steps you can take to mitigate this. For instance, I've found that most people tend to put their subwoofer too close to walls. Even if you're corner-loading your subwoofer, I recommend pulling it out at least 3-5 inches from the walls. Placing a sub too close to a wall can essentially make that wall act like a giant passive woofer, adding its own coloration to the sound. In my own room, moving my subwoofer slightly further from the wall completely changed its phase relation to the speakers. The same goes for speakers, especially if they're rear or downward ported - keep them a bit away from the walls to get the best sound out of them.

As with anything here, Audyssey can only work with the info you give it... so careful setup before running MultEQ XT is very important. There's a pinned Home Theater Setup 101 thread somewhere around here that will give you some education on how to set things up optimally. Audyssey does wonders as far as room correction goes, but it is no substitute for good old fashioned common sense setup and tweaking... and in conjunction with same can produce insanely good results.

I could turn back on the main speakers but if I tried to turn on zone 2 the unit would simply shut off. Since the party was in full swing, I did not fool with it and just had music in the den on the main speakers. Yesterday, I reset the unit and now it seems to be working fine but I have not played it as long as I did the other night. Any ideas as to why this happened or if I have a defective receiver? Thanks.

Hey Jeremy, or anyone else, i realised that I havent actually paid too much attention to my crossover settings since i originally set them months ago... unfortunately i cant seem to find anything about their "-3db point", only their frequeny response. The mains go down to 35Hz, and the centre/surrounds to 45Hz. I currently have the mains on Full Band (and double bass turned ON) and the centre on 80 Hz. Cant remember what ive got the surrounds set to...

The speakers are Accusound Thetas http://accusound.com.au/theta.html

I have the TH100/300 5.1 package, which is the TH100 mains, THC centre, THR surrounds, and the TH300w sub. Id be interested to know what you suggest i set the crossovers to.

First, check the FAQ on the second post of the first page for the proper way to run Audyssey. After you've read that and done it, you'll need to change the crossovers that it detected. For your RT800i, the -3dB point is 42Hz, so I recommend setting them to 60Hz. That's what I'm running with my RTi70 towers, and they aren't incredibly different than the RT800i. For your CS350, the -3dB point is 60Hz. I would first try 80Hz for it, then maybe play with 70Hz. Its overall response goes down to 40Hz, so you might be able to use 70 without any audible dropoff... but 80Hz would be a safe bet.

The RM101s are going to be the weak point for you. Their -3dB point is 130Hz, which is high enough that you'd be sending easily localizable bass to your sub if you actually followed the +20Hz rule. Given the overall response of the RM101s, I recommend running them at 100Hz crossover. You might lose a little audio from 90-130Hz this way, but it will help keep the subwoofer from producing anything significant over 100Hz, which should keep you from localizing the sub. You should still get directional cues and decent surround from them despite this.
