If the unit is used properly and is functioning properly, it should not overheat. If this is a problem at reasonable volume levels, then there is a problem with the amplifier section that needs attention. These are solid units that rarely fail. Further investigation is required to determine the problem. Can you update this with your location so I can provide you with a recommendation?

Hi, I have a mackie srm1801 and in the middle of a gig the OL LED came on and wouldn't go off. Input was unplugged and still the light wouldn't go off. After a while the fuse went and now there is no

It is likely that the O/P transistors have blown, especially if the fuse keeps blowing and the O/L led comes on. It's a repair shop jobbie

Laptop over heats and switches off randomly, freezes up and has a problem starting up, Running startup repairs has not resolved any problems and local computer technician can't resolve problem


Have you checked the ventilation of the processors?
this is the most common reason for overheat, poor cooling, dirt build up on fans or blockage on the tube and causes processor to overheat and shutdown the system.

A video below will show you how to do it yourself if you want to.
Although of different model but the concept of opening is just the same.

Mackie SRM-450 tweeter distorts sound

I'd just order a new diaphragm and see if that's the problem before any other dismantling. If that's not the problem, I'd take it to a certified repair shop. The fact that it's still working but not producing certain frqs,tells me you won't be able to see the problem with the naked eye.

I have a pair of mackie srm 450 and one swa 1501 the bass output in one of the 450s has no sound. i hear sound only from the high frequency part of the speaker

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.

Mackie srm-450 constant annoying hum (buzzing) even with no input plugged in

Mix, try this...Get everything in your audio system together.get a coupla power strips. Power up both speakers on that strip with no inputs, just the speakers. gotta hum(60hz)? ground-lift the strip and see if it stops. add one peice of the puzzle at a time until you find your buzz generator, if you're a mobile DJ, doing gigs in 'God Knows Where' you would be well advised to buy a "Power Conditioner" that will level out spikes and dips in the voltage servicing your gear.

Erm microwave lg mc804a has started to overheat and shutdown cleaned all the vents from dust etc now its got 2 fans 1 near the main transformer and the other at the backend on the microwave the 1 at the...

The cooling fans must be working and vents clear to ensure good cooling air flow.

Otherwise, the magnetron will overheat and it will shut down.

If this continues too long, the magnetron will be damaged.
