I have been working for this church for a few months now and am in charge of their AV. All of a sudden our power amplifier Crown CDI Drivecore 4 | 300 has given me the errors of "ch2 DCLE Detected" and "High Voltage Rail Warning" and also cut the audio to the speakers throughout the building. No matter how much research I do I cant find a fix for them. I have read every article and read the manual. I have reseated all of my connections and even completely unplugged channel 2 input and output but am still getting the same results. I don't know what to do but this has to be ready by tomorrow.
