I bought this CQ-12T about a year ago from Sweetwater to use in my jam room at home.  It has been a fantastic mixer, is in great shape and never left the house (nonsmoking environment).  With the various groups I host, I need up to 15 or 16 channels, so I have been slaving a Mackie mixer to the CQ-12T to handle some of the instruments.  Finally decided to do logical thing and bought the CQ-18T and consolidated to one mixer.  This is a great mixer with an intuitive user interface that is easy to use as a beginner, but with plenty of effects, whistles and bells to use as you get acclimated to operation of the system.  Check out the reviews and specifications for the system online.  The unit comes in the original packaging with the power supply converter and cord.  Check out the photos for condition and message me should you have any questions.
