I've tried ground lifting, but it did'nt help. Is this normal for these speakers? All of mine do it. I used to have a very quiet, clean key rig. Is this why they came out with V2? Are they quiet? Is there a mod that can be done to these to resolve this? Thanks in advance for any help!
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.

I have the same problem but it seems the problem only occurs when the mackies have warmed up for about 10 minutes. It seems they have a internal switch that turns on when sound is put through them and shut off when there's no sound and it seems it's only coming through the horns. I think mackie needs to address this problem?
I bought six of the mackie srm 450 powered mackies. I've sent 1 back due to pre-mature overheating at low input levels. In 1 of the others the high freq went out during a speech. One of the others won't power up at all. And they all hum no matter what source of power they're receiving. I was told by Mackie engineer that they had a bad batch. Maybe you have the same series batch as I do. Too much many to spend on all these problems.........
I would like to know from Mackie what serial #'s they made the bad batch from so I can check my #'s
I have My computer hooked into my Reciever (Green plugs at the tips) for audio...then i have that connected into my pioneer CS-907 Speakers...I have a constant buzzing sound....Please help...Thanks!
