Hi,

So I have a Yamaha HTR-6190 receiver and a Sharp HP21 BD player that was set up as 5.1.

Thursday night, my wife brought home a shiny new Sony S470 BD player that she won at a Ladies Night at a local casino (what a great wife, huh?!?!). I swapped out the Sharp for the Sony; love it. The load up speed is a vast improvement and watching Youtube vids on TV is a riot.

Saturday, I picked up a Rocketfish wireless rear speaker transmitter/receiver kit at Best Buy (reg $162, I got it for $80 open box) and hooked it up Sunday to some small speakers I had lying arounf the house. I reprogrammed the 6190 so it knows it now has channels 6 and 7, and then let the YPAO do its thing and re-tune the room and the speakers.

Here's the question. I only have 2 BD movies that state they have 6.1 (Top Gun) or 7.1 (The Final Countdown) soundtracks. All of my other movies say right in the Setup menus that they are 5.1. However, when played, many of them show as being 6.1 or 7.1 on the 6190's front panel display lights, and there is sound coming from the 6 and 7 speakers. For those that show only 5.1 on the 6190, no sound comes from the 6 and 7 speakers, which is correct. The 5.1 movies that play as 6.1 and 7.1 do so in either the 6190's DSP modes, or in Straight Thru mode with no DSP added, so I do not think this is not the 6190 creating channels 6 and 7.

If I go into the 6190's OSD menus and display signal info, it says there are 5.1 channels of audio, but the lights on the front panel say otherwise.

How is this possible? Is this some setting on the S470 that creates a 6th and 7th channel with some signal processing trickery? Or are the channels really on the disk?

Not like I am complaining. The Minefield scene in Behind Enemy Lines goes from great to unbelievable (the display shows 7.1). I felt like I should be wearing a rain suit watching The Perfect Storm (the display shows 6.1).

Any guidance or explaination greatly appreciated.

I assume that the "lights" on the front panel are showing the "output" signal, not the input. For example, if you tune to a DD2.0 channel via a STB or PCM 2 channel signal from a CD, the "input" information would show 2 channels, however, you would still see the 7 lights in the display if you're telling the AVR to output to 7 speakers (plus sub I assume). If you set the AVR to "stereo", then there would probably be 2 lights.

Some AVRs allow you to "modify" DD5.1 signals, while others will only "modify" DD2.0 signals - depends on how you set up your AVR too (whether you invoke the "x" part of decoding for the rear channels or not for certain incoming signals)

Thanks for the reply.

I am pretty sure the lights are input. If I tune to the Galaxie music stations on BellTV, I get 2 lights, a left and right. There are other lights on the other side of the diplay panel that show output. For 5.1 movies where the input lights show 5.1, the output lights show front, center, and surround. For 5.1 movies where the input lights should 6.1 and 6.1, the output lights show front, centre, surround, and back surround.

The 6190 also has a Straight mode that sends the signals direct from the disk to the speakers unmolested. In those modes, the input lights perform as above, and the speakers are outputting sounds that agree with the lights.

Also, I am thinking that if this was some signal processing trickery at work, it would be the same for all movies. The 6190 cannot create channel 6 and 7 audio from a 5.1 track; says so in the manual. It can only do this for 2.0 audio, where it can create 7.1.

Thanks for the clarification - the left side lights are input and the right side are output. Therefore you seem to be receiving "more than" 5.1 on some of your DVDs, BDs that indicate they are 5.1. This could be a fault of the labelling on the DVD/BD, or it could be some processing in the BD player? It could also be an issue with the AVR since the following statement makes no sense - the two should agree:

If I go into the 6190's OSD menus and display signal info, it says there are 5.1 channels of audio, but the lights on the front panel say otherwise.

I think I have my answer. Buried deep in the receiver progaming is an Extended Surround setting, which controls the receiver's ability to matrix a channel 6 and 7 from a 5.1 soundtrack. I have it set to auto, so that's where the sound comes from.

Thanks.

That would explain 8 lights on the output side, but not the input. The input lights should agree with the signal info in the OSD. Also, whenever a new signal is received on many AVRs, the display "scrolls" the new signal across the screen. This only happens as the signal changes - for example from DD2.0 to DD5.1. I believe on Yamahas for DD5.1 it scrolls DD3/2/1 or something similar.

Someone on another forum suggester I set the Extended Surround to Dolbt Pro Logic IIx. It will create a channel 6 and 7 audio, even in Straight mode. Still don't understand the input light thing.

I have the same amp and it is loaded with settings that make my head spin. I set it up a few years back and never play with it....it decides for me the best way to play the sound.
I'm okay with that.

yes, has you have uncovered ...this AVR will also matrix 5 channel to 6-7 ..

try the following in the setup manual, as you seem to have remedied already - yet with additional step.

1. manual setup > option menu > init. config ...

audio select
decoder mode
extd sur. (this one in particular)

set all to auto.

2. manual setup > sound menu > audio set

extd sur. set to auto ..this is the extra step .. i couldn't note you had (may have) done. this will bring the AVR back to 5 channels on your (5.1) movies.


i assume this is what you may be looking for ..regardless, seems you have it conquered already.

Receiver

Does your receiver have an on screen display? In the Input Option menu my Yamaha will display the format, number of channels, sampling, and bitrate.

As far as I have ever known if there were originally X.1 channels encoded not many studios would go through the trouble of removing that encoding from the audio track as nobody pays them to do that.

If you read the 5th paragraph of post 1, you'll see that the OSD doesn't agree with the lights on the panel, so the OP says.
