Phase inverted..why?


I just bought a Rogue 66 Magnum.
Its design is phase inverted.
I have to switch the polarity of the speakers cables.No big deal, but Im wondering why a product would be designed like this.

forgive me for being clueless...
but my rudimentary understanding of polarity is that it refers to the +/- charges delivered to the speaker.

As long as both speakers are running the +'s at the same time is there really an issue?

I use a Rogue Magnum 66 currently running to a Rogue m88 and have my +'s on the amp to the +'s on the speakers.

Are you saying that I really should reverse the speaker wires into the amp?
Hello Geoff,
Yes, like many tube preamps, the 66 is phase inverting. You should reverse the speaker wires on both channels as you state. You should also know that this is a subtle difference and many recordings are phase inverted so you
can't always have it in phase anyway. I hope this helps -- Mark

its difficult to hear phase problems unless you have an ear for them or test discs
its not hogwash at all...
go buy a cd with a polarity test on it and then swap around your cables...
if you can't hear the difference you have some major hearing problems
