Axiom Home Page Forums General Discussion Home Theater EP500 setup and SPL meter situation/questions.

Hello again. I have spent much time in the setup of my new axioms (M60, VP150, QS8, EP500), and at Brent's suggestions have finally found what appears to be the best spot for placement (relative to my options). Now my problems:

I can find sub/tower blending/5.1 nirvana at specific overall volumes only. What I mean is that, if I turn the master volume on the Yamaha RXV2400 up or down from a certain point it affect the bass smoothness/response. What seems weirdest is If my master volume is at -18 on the Yamaha w/the EP500 db trim at -10, it sounds AMAZING. If I simply turn up the overall volume to -15 to get more overall volume, I appear to actually LOSE BASS???? What is happening here?? It's like the volume from other channels is cancelling out some of the EP500.

Second question- Can I remedy w/my SPL meter and DVE test tones? I used it to get to this point, but what I don't know is what MASTER VOLUME setting should I use to start? I used 0 on all channels and 0 on the master volume as a starting point and calibrated all channels to 75db from there. Is that why I'm messed up? Should I have set the volumes differently during the test?

VERY happy w/my axioms, but really want to find the right channel volume settings here regardless of overall volume.

Thanks as always for you all's help.

No one loves me?? OR, I have an issue that has no answer. Cmon, you guys are usually SO good on this stuff.

I'd try checking for room nodes with the DVE disk and an excel spreadsheet. That's going to be my project this evening... I've found a similar thing with my sub. If you find you have a huge spike at a certain frequency, that's probably what you're calibrating to with pink noise. Which means the rest of the frequencies will be too low. I noticed this last night when something blew up on TV, and I didn't feel a thing...

It must've been the penguin.

I'm glad I wasn't drinking anything when I read that.

Someday I'm going to have to see that sketch.

Thanks guys, I have been dreading doing the Excel sheet thing w/the frequencies on DVE, but it sounds like that's what to do.

Likewise, my friend, likewise. It also doesn't look like it's happening tonight for me. Gah! Silly clients...

>>It must've been the penguin.

What the heck are you guys talking about ?

Is your hookup "normal", ie subwoofer line in connected to receiver "sub out" ?

Are we talking about Billy Madison here?
