Whoa pioneer fans! I do not know why this piece of dj gear is acting like this! I think pioneer is a reputable company,,,,,,but So I needed another dj controller because I have double booked on the same night and need to get 2 sets going at the same time. I have been using Numarks for a while! I only use them for general purpose fading and queuing! So I decided to get something entry level in some other brand! Even though the Numark mixtrack pro 2 is quite highly rated as the best bang for your buck! I bought a DDJ- SB2 and when I plugged it in to play is is hissing. Now I remember reading about this in the ratings, some gave it 1 star and returned it. I always look at the bad ratings, because I believe the 5 star ratings are usually some sales dick trying to counteract the sucky ratings. You can always pick them out! They say " I purchased the Dyna 1000 electric turbo dog catcher 3, and It was wonderfull! I had no problems at all!" So what's up with this model? I will probably go back to Numark! It does all that I need and works every time and sounds great .
