Hey all.
I have the following:
-ProTools 002R, running on an Apple PB G4
-R0DE NT1-A into a Presonus Eureka Preamp (Comp & EQ bypassed) with digital out
-MXL V69 ME with NOS Mullard tube into a Rane MS1b, into Eureka's 2nd digital out
-Both digital channels go into the 002 via high-quality S/PDIF
Now then, I am NOT looking for opinions on the gear, as valuable as yours may be. I am wanting to know about the polarity switch on the Rane.
I just hooked up this signal chain to record acoustic guitar. I love it. The R0DE condenser is the main mic, placed at the neck/body joint, and it sounds bright and clear. The MXL is the ambient mic, placed two feet back and directed toward the lower body of the guitar to pick up lower frequencies. It sounds nice, too.
I played a song and recorded each mic to a mono track in PT. Listening back, they each sounded great separately. However, when I played them simultaneously, the Rane track sounded horribly strident. So, I flipped the "Polarity" switch on the back from "Normal" to "Invert." The difference was night-and-day better. Panning the tracks left and right made it sound like I was playing a Jumbo on one mic and a Nashville on the other.
My question is this: What does this mean from here on out? Is it normal to have to flip polarity (is phase the same thing?) on one mic when using two? Does it have an effect on the recorded track that needs particular handling? Does polarity even matter if the tracks are panned to opposite sides? Is this a function of the difference in physical distance of each mic to the guitar (length of the sound waves)?
Any answers on this topic would be greatly appreciated.
Thanks!
Boog.
PS - Notice that I have disabled the Comp/EQ on the preamp. I am trying to record as clean a signal as possible so that I retain production options later. Keep this in mind when answering my questions.
