Are the two rear speakers in a 7.1 system/speaker setup being fed a mono rear channel when a movie soundtrack is 7.1?
Thanks, I was starting to wonder. With something like 45 views with no answers made it seem to me that not too many people knew the answer. What you said makes perfect sense and I figured that might have been the case anyway. I forgot about 6.1 with the single speaker in the back. And yes I agree that there are probably some 7.1 mixes where the backs are mono, but hopefully not too many of those.No. That would be if you were listening to a 6.1 mix.
That being said, there may be some movies that are mixed in 7.1 but have duplicate audio in both rear channels. Is there a specific reason why you asked?
would that be the equivalent of like going to see the Doctor and telling him you want a cure for your sickness but refuse to tell him any symptoms you're having/ experiencing?
That's exactly right. It's the same problem I had with my kids while in the Neo-Natal Intensive Care Unit. Doctors have a hard time finding out what's wrong with your baby since, unlike an adult, they can't respond with verbal language.would that be the equivalent of like going to see the Doctor and telling him you want a cure for your sickness but refuse to tell him any symptoms you're having/ experiencing?
Your right about that. Though I did take that into consideration as to when someone might respond, I also figured (though I might be wrong about this) that this forum "Audio Theory, Setup, and Chat" probably does not have the kind of traffic like other threads that talk about the latest projectors, flat panel displays, and/or new speakers. Funny, I was starting to think all back content on 7.1 mixes was mono, but I totally forgot about 6.1.Number of “topic views” without an answer doesn’t mean people don’t know the answer. It means those folks who viewed don’t understand the problem, or don’t want to answer. I wouldn’t draw conclusions, particularly if your post is < a day or two old.
I don't know what you mean by newer, but my Yamaha RX-A3060 which came out around 2016 is what I would think as newer...it does support 6.1 or a single rear speaker setup. When it's setup with the setting that there's only one back speaker, 5.1 will play as 5.1 and 6.1 will play as 6.1. In other words, 5.1 sources does not get up-mixed to 6.1.It annoys me that the newer Yamaha AVRs (maybe all AVRs?) no longer support a 6.1 or single surround rear speaker setup.
Instead of going into the Yamaha's menu, which can be annoying if done often, you could use the back-channel preamp outputs and connect them to an inexpensive power amp, integrated amp, or receiver (or one sitting in a closet, if available). If I correctly understand the Yamaha's 5.1 and 7.1 modes, then you need only power on and off the outboard unit as needed and keep the Yamaha permanently on 7.1 for music. Much less costly than buying another top-end AVR.
Edit: It occurred to me that you could use simply an outboard speaker switchbox to turn on/off the back channels.
We seem to be miscommunicating. If the Yamaha is set to 7.1 (i.e., back speakers are turned on) it will provide normal info to the surrounds and matrixed sound to the back speakers. If you turned off the back speakers with an outboard switchbox (the AVR remains set for 7.1), you will still hear normal info from the surrounds because the Yamaha does not know the back speakers are shut off.
The suggestion by Yamaha to program a Scene button is an excellent and easy solution. Pressing one button on the front panel or on the remote is far simpler than scrolling through the menu time and again. Kudos to Yamaha.
That is ridiculous and there is no way I would live with that limitation. I listen to a lot of multi-channel music as well and that would annoy the p*ss out of me. Although, I do use an upmixer (PLIIz, Neo:X) with MultCh music a lot of the time and never noticed any horrible anomalies.As far as the rest of the story, I recently found out through Yamaha Support that my receiver the Yamaha RX-A3060 works as designed. Here's the response I just received...
"Thank you for contacting Yamaha Support. Unfortunately this receiver, when surround back is set to small x2, will always up mix the signal coming in to fit the number of speakers enabled. The work around, as you've found out, are to either set it to small x1 or set the surround back to none in configuration."
That's it guys. My receiver does not automatically play just 5.1 when the back speakers are set at small x2, but it does when it's set on small x1, but I don't listen to 6.1 audio sources. So my solution will be to set the back speakers to none when I want to listen to 5.1 audio, (or even quad) and then set the back speakers to small x2 when I want to listen to 7.1 audio.
Crazy isn't it guys?
See underlined type. No, I never said or implied that at all. I am stating that you could simply leave the Yamaha in 7.1 permanently and shut off the back speakers with a switchbox for 5.1 music listening. The result is apparently identical, based on your posts, to telling the Yamaha to turn off the back speakers via the menu (i.e., a 5.1 speaker configuration).I may be misunderstanding what's sent to the back speakers while playing 5.1 audio sources. In stereo where a there is an identical vocal on the left and right speaker to create a phantom center channel (illusion,) and then when that same signal is matrixed through a decoder, that vocal gets sent to the center channel. At that point if I was to disconnect the wires from the center channel, then theoretically there would not be any vocal signal. There may be a hint of it, but it would be mostly gone.
What I'm understanding what Yamaha is saying about the back speakers when they type "the receiver is generating it's own audio signal from the source that it thinks should be routed to those (back) speakers." I'm assuming it's taking information from the two surrounds and sending some of those signals to the backs. If I turn off the back speakers, some of the audio originally in the surround mix gets will totally disappear.
If your saying it's taking some of the information from the front speakers and sending it to the back speakers, then there's still a problem since what ever signals are sent to the back speaker (and then turning off the back speakers) would also result in lost audio signals.
At least that's the way I'm reading into it.
At the same time however I totally agree that what Yamaha is suggesting to do might be the way to to about it. I'm just worried to do it because to me there's more than just setting up a "scene" button for 7.1 back speakers and using another "scene" button for 5.1 surround. There's the equalization (I had the system professionally calibrated) distance, audio levels etc that I'm not sure would carry over to those "scene" buttons. If so I could give it a try. If not, I think going into the menu to temporarily turn on the back speakers now and then for 7.1 audio would be fine with me.
Of course I would like it better if I didn't have to do any of that. In that case I really wouldn't mind getting a updated receiver to avoid all this button pushing as I feel it should happen automatically. It currently works that way when the system is set up for 6.1 audio, but not when it's set up for 7.1 audio. And of course I have a 7.1 setup.
Are you absolutely certain that if you select the STRAIGHT surround mode and do NOT select an upmixer, it will still play 5.1 as 7.1?? If this does not work, I agree that that is crazy.
Just FYI, Denon/Marantz don't do it this way.

But the Scene option is the best idea yet. It is easy to press Scene 1 for video and Scene 2 for music. It saves well over $1k and having to disconnect everything and re-connect it all again if you purchase a new AVR, plus having to re-enter all the menu settings.
PS: I suggest you write down all the calibration info should anything be lost due to a catastrophic power surge or other event.
