So I backed the amp gains down to 10:00, ran 8 point calibration, sub trim came back -1, bumped it up to +3 and no more clicking and switching off and on. Been watching the Olympics for 1.5hrs and no issues @ lower volume. Long as I do not run into clipping issues @ WOT, I think we are golden.

Both my subs gain are at 9 o'clock. Audyssey set them both to -6. I bumped them up to -2 and have had no issues with them turning off yet

You may want to set your gain just a bit lower and re-calibrate as -12 on Audyssey is maxed out so you really don't know if it's truly at -12 or not.
I played with the gain on my dual S1500's so that Audyssey came back at -11. I then bumped them up to -2 (9db hot).

Actually, don't you need to set the gain lower, so Audyssey will bump it's higher?

The other day I binge watched a few heavy bass movies at -5, including Underworld Awakening, Battlefield L.A., and Hot Fuzz. I haven't properly watched them since adding the PSA speakers, second V1800 or atmos, so I haven't truly watched them. :smiley:

The incredible pulsating bass from the super lycan scenes in Underworld are easily some of the most fun, over the top, and enjoyable I've ever experienced. Before the latest PSA additions, these scenes just had loud bass, but now I can feel the intensity and force of each sound wave's rhythmic ripple...super lycan!

You are 100% correct, my bad. I'll fix that.

I just got my v1500 put in this weekend, but I'm having trouble.
Can someone point me in the right direction to get this fixed?

Yamaha v663 receiver with the cable going from sub1 output to LFE input on the v1500. Its a 6' cable from PSA.
Receiver has the crossover at 80hz, all the settings are right in the middle (factory default).
Subwoofer has the gain at the 12 'oclock position, delay set to 0, crossover all the way up, room set to large.
Very little sound from the sub. Even the setup test tone gets next to nothing out of it.
Old sub worked fine until the amp died on it, so I cant use that to test.
Am I missing a setting or something? Could the receiver sub output be bad?

1)be sure ALL channels are set to 80hz in the receiver's speaker setup menu.

2)Don't hesitate to increase the sub gain higher if needed.

3)I think the main problem might be the "all settings are right in the middle". That's really the last thing you want---at least assuming we're talking about the "channel level settings" which typically range from -12 to +12. You *need* to use the YPAO feature for proper calibration or do it manually with a SPL meter. This (ypao )will also properly set your delays too which can make a HUGE difference in the audio quality. I bet once you go through this step things start falling into place pretty quick..

Thanks Tom! I'll give those a try and see how it goes.
I was just surprised that with the settings at 0 (of the -12 to +12) and the sub gain at half way, there was next to no sound coming from the sub. My last Klipsch sub shook the floor at the same receiver settings, before the Bash amp gave up on it. I'm hoping it didnt take out my receiver when it went.
I'll re-run the ypao and see what it changes. When I run it, any recommendations on where to set the gain on the sub?

@Bill Kentucky

Here is a quick setup:

-Set sub amp gain to 12:00 to start and run YPAO.

- Calibration should show -6 to -4 for the sub trim level. If not adjust the amp gain and re run calibration until you get in that range.

-after calibration, set all speakers small, 80hz cross, and bump the sub trim up 3-4db from the calibration setting.

-report back

Followed this, and I can hear/feel the sub a bit more. Turned the sub gain up to the 3' oclock position (roughly 3/4 up) and I can feel it a little more now. Still not the massive sound I would expect from this sub (certainly don't have to worry about rattling walls or floors).

The YPAO set the sub to -4, so I left it. It set front large (klipsch rf28) center to small, surrounds to small. Should I change the mains to small too? And put the sub back to 0? (Which is where it was before)
Crossover is set to 80hz.

Yes. Set the mains to small. When they are large the bass for the mains doesn't go to the sub. This could easily be why you're not hearing much bass.

I guess I'm confused as to what the crossover does then.
Shouldn't it send sub 80hz signals to the sub regardless what size my mains are?
I'll switch them to small and see what it sounds like.

Right, if your fronts are set to large they get a full range signal and bass management is not active.

Ah, makes sense.
Set them to small. Bumped the gain on the receiver up to 0 again.
Tried a couple different movies too.
The sub is definitely working. With the mains set to small, I've picked up a little more bass out of the sub but not much.
I can definitely hear/feel it, but it's nowhere near what it should be (more of a low rumble than a chest pounding explosion). Its as though the volume on the sub is turned down to 1 with the rest of the system running at 10.
Off the top of my head (and I could be way off), is it possible my sub outputs aren't giving the sub amp what it needs?

Do you have an spl meter? Or can you download one on your phone.

Using the internal testtones make sure the levels of the sub are equal to the other speakers.

Is there a lot of physical movement from the woofer? If there is and your not getting sound than that could be one thing, but if there is little to no movement I would lean twards a signal issue or gain issue.

Downloaded one for my phone.

Test tone:
Fronts and center are all 75db, surround left is 76db, surround right is 78db, lfe is 52db. That's with the receiver gain bumped up 4 from the ypao setting and the sub gain turned up 3/4 of they way.

Watching an action scene in a movie, frequency of 65hz to 2000hz stays right around 100db. 60hz is around 75db, 50hz around 60db, 40hz back up to 70db, 40hz around 60db, 30hz around 50db (meter didnt go before 30hz).

With the receiver level for sub turned all the way up and the sub gain turned all the way up, the spl meter I downloaded shows up to 61.5db on the test tone (the rest of the speakers between 75-78db).

With the receiver volume up to -10 (which is substantially louder than I ever have it), the subwoofer level turned all the way up, and the sub gain turned all the way up, I finally get the spl meter up to about 68db on the sub channel and it actually is producing a rumble that I can really feel. However, the rest of the speakers are about 88-92db at this level and the receiver volume is way higher than normal levels.

Is there a maximum/minimum voltage input for the amp on the sub?
If my receiver is the culprit here with too low of sub voltage output, would a preamp for the sub output help without causing any damage?
I did try the sub2 output as well, no difference.

When I use audyssey it normally sets my sub level extremely low and I have to bump it up. Being 20db low on the lfe channel is not out of the ordinary for me. Iv always wondered how many people have the same issue and why it sets the lfe so low. Sounds like a similar problem with yapo

But I'm like 15db lower on the lfe channel even with the sub level turned all the way up on the receiver and the gain turned all the way up on the sub. I've got nothing left to increase (unless there's something I'm missing).

Hmmm I'm trying to remeber back when I used my v373.

I know on my denon there is several diffrent screens where you can increase volume. I usually go to the test tones menu after running x32 amd make sure everything is calibrated correctly. When I'm actually watching a movie and want more or less bass there is a subwoofer level menu I can pull up quick and adjust the subs. I belive there is also a LF output menu also, so 3 diffrent places to raise the signal. If there is a menu that is still set to -12 somewhere it could be robbing your lfe.

Still though idk. I have never had to turn the gain up that high to get a decent output. Something definatly sounds wrong.

Do you have a test tone menu and a separate sub trim level menu?

However, the rest of the speakers are about 88-92db at this level and the receiver volume is way higher than normal levels.

Is there a maximum/minimum voltage input for the amp on the sub?
If my receiver is the culprit here with too low of sub voltage output, would a preamp for the sub output help without causing any damage?
I did try the sub2 output as well, no difference.
Hold on

Your speakers are at WAY too loud

Put the Mv a -0.0

Run test tones. Set ALL seekers to 75db and the sub to 80db

Now play material at regular levels. Report back

Hey guys I'm in the process of doing a g21 and s3600 comparison. Can anyone tell me how I should place the 3600s when I swap em with the g21s?

Here is a pic


Should the 3600s face the same as the gammas or should I test them the opposite way? I'm trying to avoid trying both ways because I don't want to try the gammas facing all 4 ways either. It wouldn't be fair to sit and find what's perfect for the 3600s but not the gamma. Due to time I just want to do this once.
