Question about Mackie SWA1501 Subwoofer
I have owned many SM450 Active Speakers, and one of my new ones is now doing what one of my old ones did....a problem I never fixed,but was always annoying....especially now that it's happening on a brand new one.
At some point, the speaker started buzzing, and I Noticed that sometimes it didn't, so I marked it, and have since then discovered on about 50 different occasions, that when my speakers buzz, it's always that one, which tells me that something in the grounding wiring has come loose or something.
I've never taken one apart and would prefer not to, but my tech here in Cayman keeps telling me there's nothing wrong. Is there something I can tell him?
I come across this quite a lot with the SRM450's and also the SWA1501's. One thing you can check yourself is by taking the amp off the back on the 1501 and checking/reseat the earth wires. Two of the earth wires are push on and the other is soldered. They all go to a screw/nut so make sure that is tight as well. Do you know when your kit was last PAT tested? It's always a good idea to get that done anually to make sure it's safe. If you need any parts then please do contact www.LondonSpeakerShop.com (if you're in the UK). Best Grant
