Alright so I was doing a show today... and soundcheck went fine... but as soon as the show hit we started having problems with one of our Itech 6000's . The clip light would come on, and stay on. If you turned the attenuation down all the way... a couple minutes later the clip light would go off. But as soon you I turned the attenuator up (even without any input signal) the clip light came back on. I also tried unplugging the output and it did the same thing. Any idea's?
