Members 1960LesPaul Posted August 27, 2009 Members Share Posted August 27, 2009 Ok using my PA for the first time this weekend and I have a few questions. I am going to run all 4 of my monitors on one amp but the 4 ohm load per side would be 650 and 325 per speaker which I fear is too much. I could turn the amps up about 60 to 70 percent or I think a better option is the QSC USA 1300 I have will do a 2 ohm load per side so my 4 8ohm cabs would be a 2ohm load @ a 1000 watts a side but only 200 per monitor which is right in the wheelhouse of my monitors. Would you all suggest running a fan on the amps running a 2 ohm load or is that something you would do anyway regardless. I thought of bringing fans for the amps anyway but what is everyone's opinion on it. Link to comment Share on other sites More sharing options...
Members Scodiddly Posted August 27, 2009 Members Share Posted August 27, 2009 Don't worry about wattage that way - it's not like that wattage is just going to start running through your speakers when you plug them in, it depends on how loud you turn things up. How loud a signal you send from the mixer to the amp. Turn the amp gain knob down halfway if you're worried about sending too hot a signal.

Members mshifflett Posted August 27, 2009 Members Share Posted August 27, 2009 I agree. Before I ran the amp down to 2 Ohms I would just run it at 4 Ohms and be careful with how hot you run things. Sco was right, bring down the input gain controls a bit and keep an eye on things. Link to comment Share on other sites More sharing options...
