You said a club DJ. You mentioned nothing about being a mobile DJ doing a private event. What if someone wanted him to do a private event for them? Would he have to look to anyone of you to provide the PA system so he can do the job or have to tell the person he can't do it.?One of my guys here is ranked as the #1 club DJ in the state. He has his turntables and everything he needs for DJ'ing set-up except a PA. He doesn't travel with his own PA system. He always either arranges with us to provide sound or the customer provides the sound. This is a fairly common practice for Club Dj's. It doesn't reflect on their skill level at all because this DJ is a pro all the way
I've played in places where all I had to do was bring my controller, laptop and portable HD to plug into a house system too. Big deal.
