Axiom Home Page Forums General Discussion Home Theater Well I pulled the plug on a AVR-3808!! Setup help

Definitely a learning curve on this thing.

This was my first HT receiver to ever own though, and I was able to figure everything out ok.

So I ran Audyssey and then I went into manual setup for speaker distances and my subwoofer was set to 22 ft, I'm assuming Audyssey did this. I readjusted it to 12 ft which is correct for the main listening position; should I have done this or is it set up like this for the various listening positions?

Thanks

Yup, normal behavior, it seems, for Audyssey and subs. Good eye. I adjusted mine to the correct distance for my main listening position but I seem to recall someone saying to leave it as it's a correction for phase or something.

OK I'll just mark this as edited because I can't remember which is the correct course of action.

Obviously, I need a coffee. Be right back.

Rule of thumb I use for sub distance is to add 8 feet to the actual distance. It has something to do with processing of information at the sub. John knows....

Also, it's not Audysey that sets these distances and delays. Audysey is the EQ software for room correction. Audysey just works with the AVR's auto set up.

OK instead of coffee I did some searching. To summarize several older posts.

Edited to the read [The Amps Set up Software] has trouble with subs containing a DSP processor and ofter greatly exaggerates the distance. However, some recommended that when adjusting it back, you still leave 3 to 6 feet extra to compensate for the delay caused by the DSP processor.

A couple of sub experts will likely have better explanations and advice soon. I just needed to go back and re-read as to why I was confused.

Final Edit: See I told ya one would be here soon. Sniped me while I typed.

I think that rule only applies for DSP based sub like the ep500..

Thus my words "subs containing a DSP processor".

It's not just DSP related, but all powered subs. The DSP adds more needed delay than others is all.

Thought I had added an edit statement that said "oops, didn't read murph's post first" but I must have forget to click submit!

I've always had trouble with submission.
