Question - I read the manual for the Attitude16 and really like what I was reading (the machine’s a beast). My question is that I could not find any settings for Theater Re-EQ rolloff, is that something that has to be set up in a preset?
You would accomplish the goal of (name the marketing terminology, i.e. X-curve, theater re-eq, etc) by creating your target curves. You control where the freq's start rolling off and where you may want a rising boost in bass. There is no catch-all setting to do this like in mass-market AVR's, prepros. But the target curves will give you tremendous flexibility even different curves per speaker/speaker pair. If you go back thru the posts, you'll find common examples plus many of us do our own depending on hearing preference, speakers & room acoustics.
I think you'll like playing with target curves
