Hi,
@adobslaw – It is on the request list, so we’ll be looking into it. As you hinted at, this is usually something that is set with the speaker system rather than at the mixer, though I appreciate it’s handy to have at the mixer end, especially if you’ve been locked out of the amp room and the system is set up incorrectly!
@mark-oakley – iLive has polarity switchs for both the Mix Ext In and the output socket. The polarity switch for the output socket is located at the bottom right of the ‘Outputs’ screen.
Hope this helps!
Cheers,
Keith.
