Midland mli 480 not functioning

Very rare if it is AC----look where the plug goes and if see a tiny + and - it is dc.

The humming noise could be a earth loop problem.
This is caused by having the speakers/sub woofer connected to one power point and the computer connected to a different power point.
To eliminate earth loop problems, connect both the speakers/sub woofer and computer to only one power point. Connect all your equipment to one power point using a power board.

Whatever is the voltage or MLi 698 Hi-Fi Sound Monitor ?

You could try CabletoGo.com. They usually have just about every replacement power supply available for sale or can guide you on where to purchase. Hope this helps.

uninstall the audio driver ......next install ones next u will check it

I have the Mli691 speakers and need a power cord. Where do I find one?

Unstick your capslock key if you want someone to actually read your post...

I think the problem is in your Headphone jack.


Hope this helps.

Output is 9vdc, 600 ma. center of plug +.
