OMG. I am loving this equipment. I have been using a PA box with all the equipment for years and it finally became to heavy. With the assistance of talking with Tom at Sam Ash in Vegas and he help me decide to purchase this set-up. I am very happy with this unit. I have used it for 2 gigs right after purchase and - what a joy from weight and sound-. I am very excited about the BlueTooth availability. Never had this before and have used is a couple of times and enjoyed it's use. I also took the test to see how high I could turn the system up and I did turn up to the max and had no issues with the sound. LOVING MY UNIT.
