Hi Sammy:
Either AMP will work fine, you just want to have the turn on set to normal where you turn the amp on when you want it to play the processed channels. Sometimes the Auto sensing will go into standby and take a couple of seconds to turn back on. I personally like the AMP200 for the job. And it is $50.00 dollars cheaper. And a tad more stable with the Class AB design.
Good luck with either.
