I don't know what's the more common way but I use it like mentioned above. I do not use AxeFX's USB to record, I have a strong belief that RME is more suited for recording interface. AxeFX is connected to my RME by SPDIF.
Don't use the SPDIF OUT to the RME SPDIF IN with the AXE and the RME FF800. (And yes SPDIF is stereo)
SPDIF out form the AXE is locked at 48k and can't be overridden by the clock in the RME (which you want to use as the master clock)
You would be forced to record at 48k always or UP/DOWN sample which is never ideal.
The easiest, 'most common' way to use the AXE FX and the RME FF800 is run mono or stereo out (Analog) from the back of the AXE to any ONE or TWO inputs in the RME (front or back).
The FF800 converters are outstanding. This gives you complete control in Total Mix to do as you please.
So.. as far as using the 2 analog outputs on the back of the Axe. For stereo.. should I use the 2 "balanced" XLR outputs to the 2 TRS balanced inputs on my Fireface 800? The only other option I see on the Axe is the 1/4 Unbalanced outputs just below the XLR balanced ones. The back of the Fireface has all "Balanced" inputs & outputs. I thought balanced was better for recording? Thanks so much again!
Either record at 48K and use SPDIF, or record at whatever sample rate you want and use balanced cables in and out of the Axe.
Just wanted to clarify how my setup is. Everything in my studio is "balanced". I won't be plugging a guitar into the Axe at all. I will be mic 'ing my Spanish guitar with very high end mics through some Avalon pre's into my Fireface 800. The Axe will be patched into the AI strictly for it's pristine effects. So if you were me.. would you come out of the Axe's "Balanced" XLR's into the Fireface 800 or the Axe's Unbalanced outputs (using balanced cables)? Defiantly need low noise with what I am recording. This should give me the answer I need and I really appreciate it bro!
