ArchonX, great guide there. I have 2 new front Martin Logans and a new center going into my system that has a LX-88 in it this week. Going to use your workflow for it. I tend to agree with you about the quality of MCACC Pro, with the exception of when you get to much more expensive systems that use say RoomPerfect (and I suspect Dirac Live) as I've got in another other room setup.

Loved the info you just posted in the room. How about positions of mic placement after main seat I would like to hear your thoughts
But there's only 1 mic position with MCACC Pro, unlike other RC systems.

Care to clarify? I won't be able to redo my system till later in the week. From reading his workflow, I can't see why it wouldn't handle the LX-88 in my system.

I wasn't across which models didn't have MCACC Pro, but I see the SC-79 seems to lack it. In which case, its most probably not a workflow for you - you're better off with the original tips from page 1.

Hello All,
I recently purchased a used Pioneer SC 68 and am having some problems setting up MCACC. I hope this is the right place to post this question. I've searched on the forum as well as the web in general but haven't found anything to help me. If this is has been discussed please let me know, I don't want to waste any ones time.


The first time I ran Full Auto MCACC I got a few errors saying the speaker wire were reversed, I checked to make sure then proceeded. The results across the front three channels was much better than my old system but I could not hear the surrounds (5.1)unless I climb a ladder to get close to the speakers. So I decided to change the direction the surrounds were pointing and rerun MCACC, and the fun began!


The program starts out alright, but gives different front left, right or, center speaker reverse polarity errors. Then when I tell it to continue, it does but it drops the sub and both surrounds from the test. The speakers are all M & K, LCR-35 across the front three channels, two LCR-25's for the surrounds and a sub.


I know this must be user error, any input will be appreciated.


Thank You
John

This is common and nothing to worry about. Depending upon the test tone frequency, speaker design and distance, and room interaction MCACC (or any program) may think your speakers are reversed in polarity. Check the wires and if they are OK then just move on as it says in the manual. MCACC will deal with it. Nothing to worry about and not user error (unless the speakers really are wired wrongly but it will even compensate that).

Thank You DonH50, that's what I thought.


What about it dropping the sub and surrounds? Any ideas about that?

You should really only get supposed phase errors on the surrounds (and largely because they face each other) or if you use dipoles, those will generate phase errors because they're sending both an in-phase and an out-of-phase signal.

It should not drop anything, but in MCACC, go into manual level mode and you can manually test each speaker. As long as you get a signal to each speaker (in turn) during that test, ignore everything else. Also, manually run the phase test. It will play two speakers at a time both in-phase and out-of-phase. You're looking for a solid (rather than diffuse) image in-between each set of two speakers during the in-phase test. If it sounds diffuse during the in-phase test, then either wires are reversed or the particular speaker is internally wired backwards. Just reverse the wiring. (At least I'm pretty sure that the MCACC setup has that phase test - I might be thinking about a test disc I have instead.)

Thank You Zoetmb,


I had figured out by reading Lexicon1's great tutorial how to make MCACC save my speaker configuration(5.1), on full auto it says I don't have a sub or surrounds. I'll try to run the phase test manually. I still have really low volume on the surrounds, I have to get within two feet of the speaker before I can hear it. I'm going to try pointing the surrounds a different direction.

It's common on real-world material for the surrounds to sound very low. But with the test tones, the surround (and sub) levels should sound normal. Make sure you haven't shorted any connections.
