I'm not certain I'm even asking this correctly, but if/when a mic is used alone, by default, is it in or out of phase? Or is that even a valid question? What I mean, or more so, what I'm experiencing from time to time is that when I use my condenser mics I'm not certain if I should have the phase switch on my preamps IN or OUT. It seems that regardless of which I choose, there's still an element of a 'hollow' sound that I keep getting. It doesn't happen all of the time, but when it does (as an element of troubleshooting), I'll usually record twice, one with the phase IN and one OUT, then go back and listen to the differences to see which one is less swirly. Could it be as simple as me just having lame mic position or improper gain structure on my preamp? As always, any help and/or clarification is greatly appreciated. Thanks.
