Okay, to the point. QSC rmx 1850hd. Arrived today. I have it all wired up. I set the switches on the back.. One channel has the clip light on pretty much the whole time and only puts out quiet distorted tone. Clearly some small amount of signal is getting through though. The other channel works fine. I have it in parallel input mode with the input from my bbe 383 going into the channel 1 input (channel one is the channel not working). I have tried the other input and stereo mode etc. Same deal. What could be wrong with the channel? Anyone have anything to add? If anyone is curious I am using a 4ohm Eden 210xst on each side. Any help will be appreciated. i have a gig on saturday and could use both into one channel and it would be sufficient, but I start tour next week and want to have the amp working properly first. Thanks. Michael.
