I have 2 CLR's that I wanted to compare with each other ( one has a rattle when I play bass through it ) and I created a simple amp/cab preset and after the cab the connections go to Output 1 and Output 3. I notice that with all else being the same on the CLR's and the AXE 3 Output Level knobs - the volume from the CLR connected to Output 1 is a lot louder than that from Output 3. Is this expected? On the I/O audio page, the Output 1 Level is set to +4dbu but there is no equivalent setting for Output 3. Checked manual, wiki, and forum and couldn't find anything that talked about a level difference between Out 1 and Out 3. Any help here would be appreciated. thanks ..
