Hi Ya'll , today i did a D.J. event and had a very odd to me thing happen. I hooked everything up and it sounded great. subs where good and punchy. A little while into the event i started noticing that the subs were completely off, but the amp was still on . I messed with it a few mins and it came back on. I had very good voltage going to my gear and everything. So going on with the event i noticed it did it again. so I turned the volume up and then it popped back on. and then a little bit later it went off again . and i noticed that it was coming from the mixer to the amp side because i wasn't getting any signal to the amp. i have to have a adapter for my mains on this mixer so i changed that and changed it from the right side to the Aux send and still the same thing. So what i am wondering if its the snake cord that i have going to my effects to my amp or is it the mixer? the mixer is a yamaha MG102C and the amp is a Behringer EPX2000. Thanks in advance for your input .
