Tonight I went back to work for the first time since my surgery.
Two different friends filled in for me while I was off for two weeks and both used my p.a. system.
I went in 30 minutes early tonight so I could set up and have time to fix anything they might have moved, turned, unplugged, broken, etc.
Well I hooked my Yamaha AG06 mixer back up, plugged everything in and turned it on. Everything was fine except the mixer. It wouldn't come on. It is powered by USB cable. I changed the cable. Nope. I plugged the cable in a different power supply. Nothing.
I run my keyboard into a stereo channel on the mixer, and the laptop into another, so I can play music on break. I also have a guest mic hooked up to it. And I usually hook up my digital recorder and record myself from the mixer.
Fortunately none of this is essential. It was time to start so I bypassed the mixer and just ran the keyboard left and right out into the powered speakers, then ran the laptop into the external inputs on the PA4X. I didn't have any guest singers.
When I finished I brought the mixer home. I figured I would either see what the problem was or take a different mixer tomorrow night.
I pulled up the owner's manual on the PC and found it had a Power button. I had never turned it off, and had forgotten it was there.
It is small and recessed. Evidently one of my fill-in friends turned it off. All I had to do was push the power button.
It is usually the simple things isn't it?
