Hi---
I recently built an isolated piece of furniture for my CPU. and sent it a few feet away from my control room. Silence is golden and I now enjoy it.
However, there is a hum in my Event 20/20 bas that is constant whenever they're powered. This hum was always there but never bothered me, but now with no CPU noise, it became more noticeable.
The power outlets in my studio are grounded and I'm using surge protectors. But what should I do to eliminate this noise?
Any help is always welcome,
Thanks!

I've encountered that kind of problem with my event PS5. I've switched to symetric connections and the hum disapeared. So check your audio connections. And be careful about one thing : separate audio wires form electrical wires.
Hope that helps.

Thanks for your reply. Excuse my ignorance, but what do you mean by symetric connections? Right now I have TRS (mixer out) - XLR (monitor in) cables of the same type on each monitor. Unless there is something as "matched pair" of audio cables, I don't know what symetric connections mean.
Right now audio and electrical wires from the same speaker are not touching ...
Thanks

yeah mine hum too, didn't notice till everything else was quiet and I was in a smaller room. It's mechanical hum caused by the transformer. In fact my Lucid 8824's do it too.....Event doesn't have much to say but send it back, mine are too old for that so i'll have to wait till i'm ready to crack them open and see if I can't use rubber washers/foam to help isolate the transformer....

Well, that's fine.
There are two types of audio connection : symetric ones (with Jack TRS and XLR) and ... asymetric ones. The differences are explained [[url=http://[/URL]="http://www.ziggyson…"]here[/]="http://www.ziggyson…"]here[/] but it's in French. I didn't found English links yet. Sorry

I have the new TR6... nice monitors, but they are noisy. I don't think the internals are shielded very well. I'm just outside NYC, and I do pick up a significant amount of radio, emr, etc. even with balanced connections or no input at all.

I think this is a basic limitation of the speaker itself. There isn't a whole lot of filtering on the power supply. Also the transformer sits in close proximity to the preamp section with little shielding. Short of opening up the back and modifying the amplifier, there's not much you can do... except learn to live with it.
