XLR IC with ACCUPHASE int.

Al
I have swapped the polarities in both speakers (not only one of them).
What I mean by major change – does not mean the system transferred into some thing else, but the bass became more accurate with no reduction in strength, and string and brass are not bright and edgy.
I do have a powered sub woofer, but only using it with the HT, not for stereo, and it is connected to a HT receiver, which operates the sub and the Accuphase to power the front speakers in home theater only.
For what I understand, I can either listen to home theater in reversal polarity or swap the speakers cables back when using the home theater.
Any other idea.

Thanks you

The one comment I would have is that by reversing the connections of the main speakers, for HT mode you have changed the phase relationship between sub and main speakers, by 180 degrees. If bass performance in HT mode was satisfactory to begin with, you may now find that you are getting some bass reduction or cancellation in the crossover region between sub and mains.

Perhaps the sub has a 0/180 degree phase reversal switch, or a continuous phase adjustment provision, in which case you can use that adjustment to keep the sub and mains in phase.

Yes, the sub has a phase reversal switch. and I will check this issue when I get to watch a movie :)

Guys I am having the same issue too, where I am connecting my Meridian G08.2 to my Accuphase PRE-AMP,,,, I am getting that XLR phase invert issue, What about if I used the phase invert function on my pre-amp will that work better?

Or go directly to the speaker end and change the phase there is easier?
(my friend told me that it might cause other issues is that true? )

Any suggestions? Thank you.

Jacksonkuo -- The only downsides that I can envision that would result from interchanging the + and - speaker connections would be:

1)Other source components, if you have any, would have their polarity/absolute phase reversed, if they do not have the same xlr pinouts as the cd player, or if they are connected via rca's.

2)If you have a separate subwoofer, you would be changing the phase relationship between mains and sub by 180 degrees. If the sub has a 0/180 switch, you can easily compensate for that.

The sonic effects of the phase invert function on the preamp would be dependent on the design of the particular preamp. I would expect those effects to be either very subtle or non-existent in most cases.
