Members hamsack Posted July 28, 2008 Members Share Posted July 28, 2008 I run sound for a local cover band. Usually gig 3-4 times a month. Sat night i set the monitor mix and everything was good. Then the level dropped. Couldnt get much sound into them at all. We run an old QSC for the monitors. Not sure the wattage as its not my equipment. I changed cables on the first break from the board to the amp and still the same. The amp did clip all night. It had never done that before. Even adjustments did nothing. I havent changed anything and its the same stuff they used before me when the old frontman did the sound. Ive been running the rig for about 6mo. Im curious if the amp would be the problem? There is sound comin through just not much? Im at a loss Link to comment Share on other sites More sharing options...
CMS Author Craig Vecchione Posted July 28, 2008 CMS Author Share Posted July 28, 2008 It sounds like an amp problem is a possibility, but there's not really much to go on. You wrote that adjustments did nothing...what did you adjust? Link to comment Share on other sites More sharing options...

Could also be an amp problem as Craig said. Which amp do you use? Link to comment Share on other sites More sharing options...
Members hamsack Posted July 28, 2008 Author Members Share Posted July 28, 2008 Adjusting mix level which was up barely a 1/4 anyway. The only thing running through the monitors was vocals. I could turn the vocals down and it still clipped. I do not think a short in the monitors would be the problem for the fact it was the same on both mixes.

CMS Author Craig Vecchione Posted July 28, 2008 CMS Author Share Posted July 28, 2008 True, a 'partial' short in either a cable, or speaker, could cause the amp to clip and output to be low. Something like a single wire strand making shorting contact could do this. Link to comment Share on other sites More sharing options...

If one of those were bad would it cause both channels to lose output? Link to comment Share on other sites More sharing options...
CMS Author Craig Vecchione Posted July 28, 2008 CMS Author Share Posted July 28, 2008 Maybe. Let us know what model amp it is, most likely agedhorse can tell if it would act this way. If nothing is immediately visible, you should meter the cables and the monitor's input jacks looking for a short reading. Link to comment Share on other sites More sharing options...
