Is it safe to run this amp with this speaker setup?

14 January 2014 - 08:08 AM

Hey guys, I have a Crown MA 3600, I am using one channel to run a Double 18" Sonic Subwoofer and the other channel for my Peavey Tops which I run Parallel, first thing I'd like to confirm please is if both speakers are running this amp in 4 ohms mode as the sub's both 18" woofers are not run parallel [I think] since the wires from both woofers are connected to one connector?

Need help troubleshooting Crown MA3600VZ please.

Hello guys, my cousin was rewiring his rig and he smelled something slightly burning and immediately turned off the power on his amp so he waited a while and he pressed the power button and now no power. He asked for my help, I am a pc tech but I've never tried to fix any amps before since I cannot read circuit boards, I told him I can open the amp to see what was burnt or try to troubleshoot but I would need some guidance from an experienced Electronics tech, can anyone here help in any way please?

I haven't opened it yet, I wanted to inquire here for troubleshooting help first to see if this is something I can handle. I can go to him on Saturday and can perform any testing then. He was using it Stereo with the switch in the middle. He did not notice any smoke, he only smelled something more "heating up" than burning. He also mentioned that he tried to open the outer cover but when trying to turn one of the screws on the outside cover the screw would not turn and he did not want to round out the head so that's our first issue. In my experience with computers, any time a screw appears problematic I usually tap the screw this a small hammer to loosen it then attempt to unscrew it, would this same process apply here or would there be a better strategy? I am assuming that the screws on the amp were screwed in by machines which is why he cannot remove it easily?

I found this from the manual on "No Power" "The amplifier's low-voltage power supply
fuse has blown. Return amp to Crown or an authorized Crown Service Center for servicing."
I am guessing once I can get the outer cover off I can see if the fuse has blown.

Also, this from the manual for the 2400:
All 120 VAC, 60 Hz units and all Macro-Tech 2400s have a separate fuse for the low-voltage power supply and cooling fan. All units have separate fuses or breakers
for the high-voltage power supplies

Does this apply to the 3600? If so, this suggests to me that for basically any problem it would be a matter of replacing a fuse? Help?
