Modwright SWL 9.0SE Preamplifier

Holker, there is an easy fix. If there is an odd # of pieces in a system that inverts phase (usually this only happens with pre's so that odd # is usually 1) then just reverse the the speaker cables at one end to return to absolute phase. Or is some cases one can use the phase reversal switch found on some gear. If the source or amp also (unusual) also inverts phase, then all will return to normal.

There are those that believe switching the speaker leads is better than using an electonic switch. Re: Tedmbrady's point about so many lines may be out of phase that phase reversal may be a moot point, well it depends on the recording. With that in mind, I have always wondered why so many pre's that tout the superiority of their dual mono designs don't include individual phase switches for each channel? Perhaps in the digital future it could be done automaticaly?
