Yes, just start with the volume REALLY LOW unless you want to risk blowing your headphones. They will easily get loud with small adjustments. Afaik my amp was like that at least.
But, if you have any concerns or are simply paranoid you might damage your cans, make sure you select the correct output and start with all the gain wound down as low as it can go, then SLOWLY turn the volume up. If you're getting distortion, it's too loud. If it's distorting at a bare minimum turn of the dial from the lowest setting, you most likely have the wrong output.
