Replaceing internal fuse to mackie active sub woofer swa 1501

Service manual is available for free from https://www.manualslib.com it contains disassembly instructions. If you change the fuse and it blows again, then your amp will need service.

There are many possibilities, the switch, motherboard, electronics etc. If you are a DIY kind of person and you want to try trouble shooting yourself, you need tools. Better still, take it to a service person/ outlet to proper checks.

So it's heavy? .... i wanna know exactly what happens . You turn it on and turn on the volume, pls tell mecwhat exactly happens and when with which freq
thx rich

for 110V supply use at least 8Amp fuse but for 220V supply 4amp will do.

I don't think the amps are available from Mackie any more. You can have it fixed: www.alivesoundcenter.com

Hi There, before you go out and buy any cones etc you need to check the 3 fuses that clip onto the main amp board. You can access them by undoing the two screws that are on the top and the bottom of the sub. They have flat large heads and you will need a hex key to unscrew them. If it is one of the fuses that has gone it will either be discoloured as in burnt or you will see the metal inside has split. Simply replace these with a new fuse and hey presto you should be back up and running. If you need any parts for the sub or fuses then www.LondonSpeakerShop.com will be able to supply them (that is if you're in the UK). Hope this helps. Grant (from www.LondonSpeakerHire.com)

you have one of two problems.1) the woofer is blown(most likely) or 2) the crossover is fried(rare). Take the woofer out and press on the speaker cone(softly). If there is a scratchy feeling when you move it or if it doesn't move at all, you'll either need a new woofer, or get that one reconed.
good luck.

You might also want to check that none of the push on cable ends have dropped off fom the board as this may also stop connection going through.
