I have a Fender Rumble 800 Stage and I was setting up to record tonight and ran into problems. At first I ran an xlr from the "post" out to my apogee element, but when I played, the volume was incredibly low. If I crank the gain in the Apogee preamp, its just raising the noise floor and barely raising the signal. I checked global settings on the Rumble, added more gain to the USB/Line out gain, still no difference. I switched to the usb out and plugged it into my iMac directly, nothing. It isn't even being seen or recognized to choose as an option. Really perplexed. Been using it fine for jamming and practice for a few months now. Never had any other issues with the amp (love the amp). This is the first time I have tried to record it, and it seems I am missing a setting or something. For example, the signal coming from the xlr out was lower than the signal from my SM7B mic (notoriously low gain). Something seems off, any ideas?
