At normal listening volumes, the noise is audible from a few feet away. At first I thought it might be the speakers themselves, since they're kind of old, but we switched out a speaker and the noise is still there. Then I thought it might be the wiring, since the ends of the speaker wire are rather rigid and barely pliable. But then I hooked up his cable box to the xr55 via toslink, and everything sounded fine on that input. Switch back to the mac mini's input though, and the buzzing/humming comes back. I only got to spend about a half hour with it, but I think the buzz was only there when music was actually playing.

So, am I correct in assuming the problem lies with either his mac mini, or the analog cables used to connect the mac to the xr55? His old receiver was connected to the mac in the exact same way, but there was never a problem...might anyone be able to offer me a clue here?

I seem to recall that the mac mini's analog port also doubles as an optical out. All digital receivers such as the panny much prefer digital signals coming in. So, I suggest connecting the mac mini digitally to see if that fixes the problem. You should be able to get the correct chord pretty cheaply.

ah lord help me im so frustrated

I have read this manual 10 times but I cant get programs to play any sounds through the rear 2 channels

I have a 7 speaker setup and subwoofer and when i run TEST they all work fine. I have made sure in the settings that all speakers are selected and rear speaker are set to 2

I just cant get that little SB logo on the front display for surround back to go on EVER, my sources are HDDVD over optical and directv over coax digital.... i push DTS etc etc during movies my surround backs dont work at all

please tell me what i am doing wrong.... grrrr, I am so lost on this one
post #3454 of 3606
Most movies are 5.1, they do not have 7 channels. Do you have Dolby Pro Logic turned on?
post #3455 of 3606
I agree with castaban... you will note on the bottom of your remote there are 4 buttons. The PL IIx and the NEO:6 are designed to expand 5.1 tracks into 6.1 or 7.1 systems ASSUMING you have the correct type of signal on the media. You will need to read page 15, 17, and 18 of your manual carefully several times to start to get the hang of it. I've had mine since they came out and I still am learning how it works.
post #3456 of 3606
I've searched like crazy through this thread but i can't get the answer i'm looking for. It was covered a few times in the thread but is still a little confusing to me.

I have a 5.1 athena setup with the xr55. Now i have the xr55 set to 5.1 with no surround backs. Anytime i'm running my 360 into it via digital audio cable. The only thing on the screen of the xr55 is DD Digital, nothing about dd pro logicII. From what i read you should be able to get Dolby Digital PLII with a 5.1 set up. In the manual it says to push the DDPLIIx button on the remote to get Dolby digital PLII. When i do that of course it says no surround back speakers found and doesn't allow it. What am i missing here? is it already playin in dolby digital pro logic II or there something i need to change? Thanks for any help

I did a little more messing around with my reciever and found it let me push the DDPLIIx button when i'm on a tv channel with only left and right speakers working. Is this really what DDPLII is? doesn't have anything to do with a 5.1 source like the xbox 360?

When that light comes on, it means it is being sent a DD signal, which is usually 5.1 channels. You can double-check by looking at the speaker display on the receiver. If five speakers are shown (LRC/SR/SL) then it's putting out five channels. You shouldn't need to use PLII with a DD5.1 signal because it's already a 5.1 signal. Wikipedia is useful:

My apologies in advance for resurrecting an issue that has been touched on in previous posts, but I just got a new 52" Vizio LCD and I am trying to decide the simplest, easiest, and least complicated way to hook it up to my XR-55, DVD player and HD cable box.

I see that some people here advocate running their video components to the XR-55 first, then out to the TV.

Others run their cable boxes and DVDs to the TV first, then just run an audio signal out from the TV to the XR-55.

I have always done the former. But I am slowly coming to the conclusion that running video components through the XR-55 is a lot of work for not much payoff. It seems to me that the best video signals are achieved via the shortest and fewest connection from the source, i.e., DVD-to-TV, antenna-to-TV, STB-to-TV. It also seems that a direct set up would significantly cut down on cable clutter and make operating the system much easier. The receiver would be left on a single input - "TV/STB" - and all input switching would be done via the TV remote.

Am I missing something? Can someone please explain exactly what the disadvantages are, if any, of running video components directly to the TV and taking an audio signal out from the TV to the XR-55?

Thanks.

Your logic is good - the only thing you need to be careful of is if you use HDMI to the TV and the digital out of the TV to the receiver - AND IF THE 5.1 ENCODING SURVIVES. Many TVs cut the digital out down to two channels.

I would have attempted this route, but my LCD is wall mounted and it would have meant pulling more cables through my wall.

There is another option. I hook all video directly to TV. But all audio comes to XR55. I am an advocate of most direct route. Using TV's Audio out will create another node in the signal path. Works beautifully if you have a good universal remote. Also I am not 100% sure about the quality of video switching of XR55.
One reason people might use video switching in the receiver is when then run out inputs on TV. Also depending where the physical location that might reduce the cable clutter, not increase it.

Yeah, my setup is a hybrid of this.

XBOX360 component -> XR55
XBOX component -> XR55
Cable box HDMI -> TV
XR55 component out -> TV

All audio is from device to XR55 digital in. Disadvantage of this is, of course, I have to use remote control macros. If you have a remote that can do it though, it isn't a big deal.

post #3463 of 3606
With Harmony, you can do it very easily, without Macros (Well Harmony sets macros for you and you use it without knowing it)
post #3464 of 3606
Excellent thanks.

Taking video to the TV and audio directly to the XR55 makes a lot of sense, except that it complicates switching instead of simplifies it. It means every time you change the source, you have to change inputs on both the receiver andthe TV. I am trying to simplify things.

castaban: If the Harmony works as you say, problem solved. Does it have any problem switching inputs on your XR55? The programmable remotes that came with my TV and cable box can turn the XR55 on and off, but for some reason can't switch inputs.

xnappo: I have written to Vizio and asked them if 5.1 coding passes through the set or is reduced to two channnels in the audio out signal. That really seems to be the key question.

Yes, that is the key question. I know that neither of my Panasonic plasmas pass 5.1 via its audio out.

I need help! My Panny XRR55 is not responding to my remote (new batteries). It will sometimes turn it off if I stand next to it. Is it the receiver or the remote. I don't feel like digging my receiver out to take it to CC on warranty.
post #3467 of 3606
Just introducing myself... I just ordered this unit from Beach Audio. It will be taking the place of a Denon 1803 my friend will be using. I'll be back to post my thoughts when I can...

cheers,

Hello how are you guys doing tonight. I've just read all 116 pages.

I am just going into separates stereo system right now, before I always use computer speaker system although I like to read stereophile and absolute sound, I just don't have budget to buy expensive equipment.

I recently bought a 20 year old Vandys 2C still in good condition. I wonder whether it will work nicely with XR55. Vandys got 10" passive radiator, 8" woofer and midrange and tweeter. Previous owner drive it with 36W / channel tube amp and it sounds quite nice. Planning to use it in stereo mode only, with biamping/biwiring.

I also planned to listen to DVD-A. My DVD player (Panasonic DVD-S52) doesn't have 6 channel analog output. Can this receiver decode stereo DVD-A through coaxial input/output?

I appreciate any thoughts you would give. Thanks in advance.

i've spent a few hours searching this thread, but i haven't found an answer to a question i have that's similar to the one above. i have a samsung DLP (HL-S5087W), and i just got an XR55 to replace a fried onkyo. i run all my components to the tv (some via an HDMI switcher), then digital optical out from tv to one of the xr55's optical inputs. i also run digital optical from my directv HD-DVR to the xr55's other optical input. i can get surround from my directv DVR no problem, but the input from the tv only comes in in stereo. i know the issue was raised that many tvs cut digital out down to 2 channels, but i had this same setup on my onkyo and had no trouble. would that be because the onkyo was analog and this is digital? i would rather not run audio from each component to the receiver, but i will if i have to. thanks for any help.

I have never seen a situation where having a display in between your audio source and your audio input on an AVR works correctly if even at all.


You think you got DD like this before? Usually only from the internal HDTV Tuner.

That means nothing. Your room, interrations with other components, cabling, power quality, how much beer you guys were drinking, source material, system setup, etc. could easily mask the differences. Of course it will sound different. I would be surprised if two manufacturers could assemble components using completely different parts and get them to sound identical if they wanted to...any more than 2 automobile makers could assemble 2 cars that drive exactly the same. You should get out a little more and realize that there are other views out there...and many of the people with the other views (outside the avsforum party-line) have systems that will put yours to shame.

My Panasonic plasma passes 5.1 thru to my XR57 via optical cable.
post #3473 of 3606
From HDMI input you get DD 5.1 out the optical?

I am skeptical, I have never ever seen this work.

I did the comparison, not you. Please don't tell me to get out more, I have been buying audio equipment for well over 40 years which is most likely longer than you have been alive.

If you are so smart why don't you simply go out take any two amps that you wish go make an appointment and take the Richard Clark $10,000.00 challenge. No one has won the $10,000.00 to date and many have tried.
post #3475 of 3606
Sorry, I didn't mean for you to take this personally and I realize after reading it the next day how easily that could happen. I meant my comments more for the GROUP, and I used the phrase "get out more" to encourage the group to explore alternative views (such as Stereophile, The Absolute Sound, other high end publications) which are completely opposite the "all amplifiers sound the same camp". There are many factors in amplifier performance such as output impedance, distortion spectrum, ability to handle low impedance loads, etc. that produce real differences that can be measured as well as heard, BUT... not everyone can hear the differences, especially when there are many factors in an unscientific group listening test that will MASK the differences. There is nothing wrong with that...we are all different and some people hear better, others see better, others talk better, etc. etc.
post #3476 of 3606
expanding upon noway1's good post, unless you have a properly treated room I think most source equipment ends up being largely indistinguishable from most other source equipment if you make a reasonable attempt to objectively find differences between them. They all get "sludged up" by the room flaws, so to speak.

If you are unwilling to treat your listening space, I wouldn't bother breaking the bank in hopes of getting significant improvements in sound performance. Concentrate more on things like component size (to best fit your available space), looks, budget and feature set, as you probably won't find a whole heck of a lot of difference in sound between them.

I've owned four different receivers, an HK 330, a Cambridge 540, an Onkyo 502 and this Panny 55 (sorry, I'm not providing the complete model numbers on these, but you all probably have a good idea of which ones I am talking about). Each time, I thought I heard SOME difference between them, but to be perfectly frank, I have no idea if that was expectation effect, confirmation bias, unmatched levels during comparisons, etc. Even when I heard differences, and I did a bit, my room is untreated and echoes and room nodes up a storm with bouncy bass waves varying like crazy depending upon the listening position. I don't trust my own opinions.

For now, the Panny 55 is good enough. It's compact and cheap.. the main reasons I've kept it over the other models I've had. I'd like to say that I think this receiver sounds much better than it's price would indicate, but I can't really.. I just take a measure of comfort from living off of the "reputational glow" which many others have bestowed upon the Panasonic family of digital receivers, in addition to my primary pragmatic requirements.

Now.. once I finally get going on incorporating room treatments, the experience of others seems to suggest that things like amps and cd/sacd players, etc., will begin to reveal their quality differences. Or, I still might not hear much of any difference at all. time will tell.

If you are referring to my post, my source is RF cable from the wall to the plasma. I said nothing about HDMI. If you are not referring to my post, never mind.
post #3479 of 3606
Hi guys, quick question for you... I've been considering the KEF 2005.2 speaker system. CNET says not to match these speakers with less than the best-sounding receivers, and I've read the same tip from other reviews. Any thoughts on how these speakers would match up with the XR55? I want a great receiver, but I don't want to have to dig too deep into the wallet (Amazon has the XR55 for $160). Thank you!
post #3480 of 3606
In that price range? There probably is nothing better no matter what speakers your driving.

A word of caution, I do run out of power with this model frequently listening to music.
