The "official" Yamaha RX-V673 thread. 7.2-Channel Network AVR - Page 32

I've got my sub at -15db, and my receiver (Onkyo HT-R960) set my sub to -1db. If I wan't more base I turn up via the AVR from -1db to +5db's, but so far with what I've got I haven't found the need to increase bass.

Main level. Take it to 0 to start with. That should be pretty noticeable.

The subwoofer trim is a new feature. It looks like a per-input setting (like volume trim). So change the main subwoofer level when you want to change the amount of bass for all sources, and change the subwoofer trim to change it for a particular source (e.g. if bass is too heavy when you watch TV, you can lower it for that input without affecting others).

Edit: it's not what I thought it was. See here.

Nice. My 671 doesn't have that. Fortunately my sub has Movie, Music and Night modes for the same purpose but I have to hit a button on the sub to change it. It changes the crossover, phase, volume and eq mode for each input.

I ran YPAO and it set my rear speakers at 28 feet and they are only a few feet away. Is it measuring diameter?

Diameter of what?

But the speaker distances should be accurate, except often for the subwoofer where the effective distance might be larger than the physical distance due to internal delays. I would set the distance to the real measured distance, and also maybe check that they sound OK to be sure it's not some problem with the speakers that was causing the wrong distance.

Yeah, I reset the sub-trim level back to 0 and will adjust the main only. I plan on rerunning YPAO and before I do, turn down the sub volume on the sub and let the receiver handle the sub volume.

Yeah, gonna turn my sub volume down to about -15 and rerun YPAO. It should place the sub volume on the receiver closer to 0 and then will adjust from there...the main level.

I checked last night, because that would be a pretty cool function to trim the sub level on the receiver for each input, but when I go into the options and volume trim section, the input on the volume trim shows CABLE/SAT input (I renamed it from HDMI1), but the input on the sub trim shows All. I wonder if there is a different setting somewhere that changes that input from All to say CABLE/SAT or HDMI2.

When I ran YPAO initially, it set my sub distance at like 26 feet, when it was only about 14 feet from the mic. When I set my volume on the sub to -9db and reran YPAO, it actually set it to the right distance, give or take a couple of inches.

I'm going to rerun YPAO today and before I do turn down the sub volume to -15db and see what happens.

Looks like "subwoofer trim" is not what I thought it was. From the list of features on the Yamaha web site:


Not exactly sure what it's doing, but it's not a per-input adjustment. It seems to be adjusting only the lower frequencies that the sub alone is playing, rather than adjusting everything the sub is playing (which would include some frequencies that overlap with the mains). At least that's how I interpret the description.

Just got my new Yamaha RX-V673, and I'm struggling with one thing.

My subwoofer (SuperCube 2000) seems picky about automatically powering on. It seems like i need to fiddle with the sub cable (plug/unplug), or crank the music super loud (doesn't consistently work) before the sub kicks on. It just doesn't seem quite right.

My speaker config, is 2 front smalls.

Once its on, its great.

Any suggestions?

What's the subwoofer level in the receiver currently set to?

There's more chance the auto-on feature will work if the sub-level is high in the receiver. So you can turn down the sub's own volume control and recalibrate. You should then have a higher sub-level in the receiver (for the same amount of bass as you had before). If auto-on still doesn't work, repeat until the sub-level is close to the +10dB limit (that's the best you can do).

Adding a y splitter at the sub will also increase the signal. Depending on the sub it really doesn't matter whether you use left/and or right rca's.

Makes sense. You can achieve basically the same thing by setting the receiver crossover 10 or 15 higher than the sub thereby reducing overlap.

Diameter of the room. Just a wild guess cause its so far off. I also have my surround speakers on a wireless setup. Could that affect it?

Shouldn't.

It's measures the delay of the test tone to the mic and then sets the distance. The placement of the sub will have an affect due to the soundwave travel. So if your sub is in the corner and there are obstructions, it could affect the soundwave travel and may increase your "distance" or delay. Maybe try the sub in a different spot and recalibrate.

I ended up increasing the sub volume to -12db and resetting the sub trim on the receiver to 0.0. I reran the YPAO and it set the main level sub on the receiver at -0.5. I increased it to +2.5db and I think I'm liking the bass level now.

It also set the XO to 80hz and I was going to increase to 90hz, but since my fronts can go to 61hz, I'm just going to leave the XO at 80hz.

I did change the C to small because it set it to large and I also increased the rears to 0.0. The YPAO set them to -1.5db, but it was difficult to pick up any sound from my main seat.

Other than that, my LR are both at 0.0 and my center is +1.5db. I think it sounds pretty good.

Does the YPAO mess with the PEQ too? When I changed the rears level, do you think it did anything significant to the PEQ settings for those channels? I read about manually updating the PEQ for all the channels, but it sounds rather complex and I'm not sure if I want to start messing with those settings.

If there's extra delay due to buffering data on the wireless connection then that will make the speakers seem further away. If this is the case you would want to keep the YPAO distance setting.

YPAO does use the PEQ, but if you change the levels manually you don't need to change any PEQ settings (you're only changing the overall level, you're not changing the PEQ filters).

I don't see how it could eq them from just a couple of test tones but it might. I trashed all my YPAO settings other than speaker distances because it seemed close enough when I saw 3 different results 3 times in a row. If it sounds good then I wouldn't be messing with the eq unless you are sure what you are doing. Although if you do get it all messed up in Manual you can always just use Flat, Front or Natural. It took me quite a while to figure out all the capabilities of the eq and get it perfect but its worth it. I didn't do it all at once. I just played with it here and there when I had the time but once you figure it out it doesnt take long to make changes. btw I have the 671 so I'm not sure exactly how much of this is relevant. Doesnt the 673 have multiple location YPAO capabilities? Its been a while since I compared the two.

Cool...good to know...thanks!

Yeah, I didn't think of the different PEQ's by default. It actually set mine to Flat. So I guess I can try Front in a week or two and see what that does, and then Natural....thanks for the heads up Bond!

The 673 doesn't have multiple mic location measurements, just a single. The 673 manual shares with the 773, which does have multiple mic measurement capability.

Not sure why they wouldn't just put multiple measurement capability for every receiver capable of YPAO. I mean is everyone supposed to sit in the same spot?

You're talking about just volume levels right?

Can anyone tell me how to turn off the on screen volume display on my rx-v673?

On screen, setup, function, display set, short message off

Yes, I meant he was only changing speaker levels, which affects volume but not EQ.

Perhaps a silly question but I am confused about something on my Yamaha v673 during movie playback... I know I have used the input selector to set movies to dolby prologic before, but on the last few movies I have put in my bluray player, "dolby prologic" is not one of the listening modes to choose from when paging through the choices. Currently it's Drama, Straight, Roleplaying, etc. etc. I have not changed anything in my set up. Do some movies not have that option? There's gotta be a simple fix for this...

I'm driving the Definitive Technology 800 monitors with a 1000 center channel. Using an older sub until I can get the matching sub, but man I have really been missing out!! Good stuff!!

If you have a 5.1 setup Pro Logic will be an option for a 2.0 (stereo) soundtrack to create the extra channels, but it won't be an option for a 5.1 soundtrack because it would have nothing to do (no extra channels to create).
