Simple set up:
3602's in parallel. JBL SR4732s on each channel, and another running two subs in parallel. JBL SR4719s
In parallel, channel one is working exactly how it should. But channel two, my horns do not come through. Now, I have 10 of these amps, so far I have ran through about 5 of them and im getting the same issue.
I have talked to techs at QSC and they are saying that it may be an issue with the amp. But I am having a very hard time believing ALL of these amps are defective!!
It isnt the speakers because no matter what speaker I plug into channel one.... WORKS! But channel two is nothing but muffled mid range.
I have also failed to even get signal from the sub on channel 2!
I have tried separate audio sources and cables. I am basically just testing it with an ipod through either my presonus audio interface... or a simple analog mixer.
Am I missing something?
Could it be the way the cables are wired? Or the internal speaker wiring?
I made all the NL4 myself and I know they are all consistent with +/-
Any input or thoughts would be greatly appreciated!
