Infinty epsilon loudspeaker phase adjustment on servo control


On the back of servo control of  infinty epsilon loudspeaker there is a switch to be adjusted to either  0 or  180 for phase change . This is to be adjusted with amplifier and loudspeaker . If this key is set on the wrong phase a very damaging signal runs through the amp and might  damages both amp and loudspeaker . It is not clear how this can be avoided from amp to amp and it is by simply by luck to have the correct phase. Any suggestion how this can be avoided prior to start of woofer amp ? The wrong set up could seriously damage both amp and loudspeaker !
Thanks

If you can't spot anything wrong, I myself would drop back and punt to Infinity on this one. I'm thinking it seems like it may be some sort of compatibility, setting or connection issue with the servo box and your amps...assuming the SCU does not need servicing. Have you double checked all your connections relative to Infinity's instructions, including polarity?
