QFT. Or, maybe you have your speakers/speaker wires set up in reverse?
I always thought speakers for home listening ought to be set up with the left/right in relation to the listener facing the speakers, not as the opposite 'stage left' and 'stage right' as if there was an imaginary stage between them in refernce to which you assign the channels. So, just change the channels to which you have you home speakers assigned and then have no problems...
That's the ticket. My speakers are set up as stage left/right so facing them reverses the audience image.
Dumb question, why would anyone set up a pair of stereo loudspeakers stage right/left? It makes no sense. When you are facing any stereo pair of speakers, and pan the balance knob to the right, the right speaker facing you should be the one that you are hearing, and visa versa.
As a side note, you have to be careful when patching out of a SBD regarding the R/L orientation. Sometimes, a right channel out is actually stage right, not the right stack facing the stage from the audience, and this can really muck up a matrix recording due to crossed image. Good idea to ask which way the SBD outs are oriented, just in case.
