You can run ypao under pattern 2 in the manual setup and adjust it to have the crossover and levels you want. Then you can flip back and forth between the setting you have now (pattern 1) and the ypao setting (pattern). Easy and quick way to compare your manual settings vs ypao.
BTW, I did the y-splitter with my dual sub's earlier this week. I also like it better.

Does YPAO give you the option to select the pattern or is it something I need to select prior to running YPAO?

Not sure why running the Y-splitter sounds better, but it certainly does on my system too!

Using the Y-connector helps things because the big advantage of two subs (or more) is that they can interact in a way to reduce the overall variation of the bass frequencies -- IF they are run in mono (ie, using a Y connector).

Depending on the model both subs are getting the exact same signal (mono) regardless of whether you use a splitter or not. Just because you have 2 preouts doesnt mean theyre stereo.

Over at the Home Theater Shack, they reviewed then 3020 and discovered that using both sub inputs distorts the bass, and, you guessed it, the recommended solution was to use a Y adapter with 2 subs. Somehow, the Yamaha engineers dropped the ball on this one.

So I have had my Aventage A1030 for a month now and I have to agree with what a lot of owners have said about the sub pre out levels and it seems to be much lower than I have heard in other brands. I have to set my sub volume to 3 o'clock, sub trim to +5.0 and receiver db level to -2.5 just to get what I feel is suitable bass response from my PB2000. Comments would be appreciated.

The sub preout level is not as high as some other brands (or older models of Yamaha receiver) but it doesn't matter. Part of the normal calibration process is to set your sub volume and level trim to the required values.

Yes, but the 2030 has a setting where you can select Mono x 2 which theoretically should send the same signal to both subs. Yet running the Y-splitter sill sounds better and louder. ?!?

Key word being "theoretically" since your simple test of using a y-splitter demonstrates that 'monox2' is not simply sending precisely the same signal to the two outputs. (This assumes there is a measurable difference, and not just an expectation bias resulting in a subjective impression of a difference.)

ive discovered that using both the sub outputs to my pair of Velodyne SPL-1200 Ultras .. running two subs seems considerably less punchy than just one ! should i use Y splitter as mentioned above to get the best bass response?

What a weird design

in saying that, i might need to play with phase settings

Based on the experience of others, I would say a Y adapter is the way to go. Even with dual (or more) subs, it is still a mono signal, so as long as the distance between your listening area and both subs is the same, you can get good results running them with the Y adapter. I've not heard of anyone who is happy with the results of running them separately through both sub per outs...

If "less punchy" just means the subs are not playing as loud, then there's nothing wrong. Any time you change the way you connect the sub(s) you should recalibrate, and that will restore the volume.

If the receiver is playing the same thing on both sub outputs (which it always does for the 1030, and for the higher models it's an option in the settings), then the volume should be the only difference. I certainly wouldn't be surprised if the output level is different using one connection method over the other.

I had 2 subs hooked up separately with my 675 and was happy with it.

"Less punchy" can also be "more flat" which is, of course, desirable and often the result of having two subs well placed in a room. I would call that "less boomy" but many people call that "less punchy".

Good question. Especially since it's hard to imagine many scenarios where someone is using the sub INPUT (as the OP specifies) on their receiver. OUTPUT? Yes, but INPUT? Rare.

This is what he had to say:

Unfortunately, YPAO misses on equalizing multiple subs. I was truly shocked that Yamaha did not get this right. YPAO measures the subs separately for distance and levels (which it should), but it also measures the subs separately for equalization. Unless you are one of the very lucky exceptions that has a room with subs situated just right, it will be nearly impossible to equalize subs independently and then combine their equalized responses to result in a flat response. I have tried on fifty-eleven occasions, numerous different subs, numerous different multiple sub locations… and I cannot make it happen. YPAO should instead get the distance and levels between the two subs set, then measure all subs together to determine the filters needed for equalization, which is what Audyssey does… and it works. I thought maybe the SWFR Layout selection of ‘Monaural x2’ would combine the channels, but no such luck. Graph 5 above shows what happens when you flub the dub as Yamaha has done. I got the subs all nice and equalized using several parametric filters (with all subs combined) and rerun YPAO, which in turn messes up the response.
My suggestion if you have multiple subs and they are equal distance from the main listening position, is to use only one sub output on the 3020 and split them to your amps (or parametric EQ). This way the 3020 will be equalizing the combined response of all subs in your system. If the two subs are not the same distance from the main listening position, you could use something like the miniDSP 4x10, which would allow you to set the distance/delay of each sub... and it provides a parametric EQ as well. If you have large peaks, it is always good to try to eliminate those prior to running the auto-eq.

Bingo!

Thanks for posting. This (also?) explains why monox2 is not really the way to go. Which is a shame, because it would be nice to have distance and level adjustable per sub on the receiver. As it is, using phase and gain on the subs, one can do that. But it's more work smile.gif

He also stated this:

The 3020 accommodates a dual subwoofer setup, and as I was setting the speaker configuration I noticed there is a ‘SWFR Layout’ option that allows me to select ‘Left + Right’, ‘Front + Rear’ (which I selected) and ‘Monaural x2’. I ultimately tried YPAO for each selection and could not determine any benefit to being able to select a layout, the measurement results yielded the same regardless of the choice.

If you have the equipment, knowledge and time to setup your system manually with no use of YPAO then youre way ahead of most people. I doubt theres anything I could tell you that you dont already know. In fact I would expect you to be answering questions instead of asking any.

Haha, yes I'm quite competent at setting up my system and have a relatively decent understanding of sound/audio. But what I'm not clear on is why running the 2030's dual sub outs results in lower output and less deep sounding bass, while using just one of the outputs run through a y-splitter to both subs sounds superior with much higher output even though I'm NOT using YPAO?!

If youre using the same subs in the same place the only way that makes any sense to me to get more output is because youre using more volume.
If you have the right equipment and know how to use it it should be easy to determine whats going on. What test have you done to determine that you get much higher output when using a splitter?

This dual sub discussion is very interesting. I added a second SB Ultra13 to my 5000. I didn't notice much of a difference in bass response in my 14x20 room. I have one sub in the front left corner (13 feet from listening position) and one in the right rear corner (5 feet from listening position). They are configured as front/ rear on the 5000. Both subs gains are up to -5, which is almost all the way up (per SVS). Ypao still set both subs to +2. If I wanted to level match them to the rest of the speakers with my RadioShack Spl, I'd have to increase the level to +10 on the left front sub, and +3 on the rear. That just seems way to high. Any 5000 owners experiencing any similar issues, or trying the y splitter?

Both subs gains are up to -5, which is almost all the way up (per SVS). Ypao still set both subs to +2. If I wanted to level match them to the rest of the speakers with my RadioShack Spl, I'd have to increase the level to +10 on the left front sub, and +3 on the rear. That just seems way to high. Any 5000 owners experiencing any similar issues, or trying the y splitter?

In my situation...

Dual Martin Logan Depth i's, equal distance left and right from the center next to my mains. I am using both sub outs on the A5000 configured as dual mono. Volume on sub is set to 50% (5.5 in my case). YPAO set the volume on my subs to 0 and +.5 each.

I have played with and tweaked SBWFR Volume Trim (input trim) in the options settings to acquire the bass output desired and I am getting plenty of bass. Enough to shake/rattle the LED high hats in my ceiling type of bass. So much so that I had to get the ladder out the other day make sure a couple of the lights were seated properly and remove the rattle.

Using a Radio Shack SPL, my subs measure a couple of db's higher than the rest of my speakers which are set to 75db at reference volume (after a little tweaking) because I like it that way. wink.gif YPAO did a pretty good job with the measurements in my case.

I am one that is having no problem using dual outs and I still have plenty of room to turn up the subs another 5.5 on their volume controls and another 11+ db on the sub level output from the A5000 which I would be insane to do.

Weird.

Maybe a silly question.I own CXA5000 for 2 months but I don't know how to setup all parameters from front OSD without ON SCREEN menu.The bass response is still weak,I can't figure why,after I raise the vol.,sw trim.smile.gif

It's easier to use the web control interface, assuming the A5000 is connected to your network (especially if you don't have a display connected). Enter the IP address of the A5000 in a web browser, with /setup at the end. e.g. 192.168.1.135/setup (substitute your own IP address).

For the weak bass, did you run the YPAO auto setup? Check your sw level (not sw trim which is something different). If YPAO set it very high (close to +10) turn up your subwoofer's own volume control and run YPAO again.

Also make sure you have the main L/R speakers set as Small, otherwise the sub won't be used for stereo music so changing the sub level will have no effect.

Hey Folks

I have the CX-A5000 and have a question or actually need some feedback from other Yamaha CX-A5000 owners. Back a bit me and the wife were out wasting a Sunday looking around in downtown Eugene Oregon and stumbled across a hole in the wall privatly owned audio store. We went in and started looking at old Vinyl records and man the memories of spinning vinyl when I was a teenager started comeing back and I mentioned to my wife that the Yamaha's we both have (A RX-A3010 and CX-A5000 repectivly) had phone inputs just for turntables. So after spending hours in this store looking at old albums and going down memory lane turntables kind of left my mind. Well last night my wife again asked about turntables and I told her I could do some research maybe find something used ect, when she said thats to bad as she had been doing research since our visit to Eugene (that was in February) and it would be a waste of time since.........She had bought me a Music Hall MMF 7.1 and it would be here on 5 June. So know my question and hopefully feedback from you guys is how does a turntable sound on the CX-A5000? I haven't spun a record in over 30 years and am really looking forward to going back to something old but new in a way.

Any experiences? Advice?
