great easy to use unit that has more features than most in its price range. The display is also very large like on the really expensive models, this one was not cheap when it was new. Very good large sound quality. Easy to set up the sound with the graphic equalizer and plenty of crisp highs and good mids as well. These will be held onto when people realize how good they sound! So good i had to make a review.

none at all

This is a cheap unit good for a rec room 100 watts front and center 50 watts rear
Sound is just so so. Picked it up for $50 bucks
