I can not seem to get the hardware ALC working on my flex 6500. Heck I am not even sure how it is supposed to work. I am reluctant to stop using it as I dont want to damage my al 80 b. Could it be that the amp is not sending an alc signal to the flex? I do have DDLutil but find that under my current operating system (windows 10) some of the functions get strange so I have opted not to use it as a way of limiting the output of the flex. Any help would be useful to this perplexed and frustrated newbie.
