A recently retired from being a flight attendant. And I want to DJ full-time. I used to be ADJ longtime ago and I wanted to get back into it. I bought the tractor S3 because I really wanted that 1 instead of the other one the Exo. Law on the left channel does not work. And that's a problem with my speakers that I have. I have the Bear and chair Euro. Live b one twelve d thousand watt speakers, so could someone please help me?
