I wouldn't worry about it. I just got one and mine does the same and my REV2 did as well. However, mine has a noticeably loud static noise (hissing) out of the outputs. All my analog gear does the same, so I know that at least some of this is normal, but I usually only really start to notice it with my other gear when the volume is above the halfway mark. The static noise doesn't raise or lower with volume changes either like my other gear. Also, I get a loud buzzing when USB is connected, which means the editor app is useless. Is that just the way the AS-1 is?
