My EP350 hummed when I fist got it/him/her?. I removed a small screw near the power supply. Forgot what it's called. That stopped my hum. Some sort of grounding screw.

Hi Stu.D,
If you have a cable box or satellite receiver hooked up to your system it might be the source of your problem. Disconnect the RG6 cable feeding your cable/satellite box from the wall outlet. If the hum dies away then it is a ground loop issue. If you remove the sub cable from your EP600 does the hum stop?

Here is a link for helping you trouble shooting it - EP600 Trouble Shooting Guide

Don't hesitate to dial Axiom's toll free number (866-244-8796) if you need further assistance.

Good luck !

Hi Stu!

It sounds like you have a ground loop going on. There are a few real quick troubleshooting steps you can take.

1) Remove the ground screw on the amplifier at the rear of the sub. Does the hum go away?

2) Try a 3-2 prong adapter on the end of the subwoofers electrical cord. Does the hum go away?

3) If the answer to 1) is yes then disregard step 2) and your problem is solved. If step 1) does not solve the hum proceed to step 2). Does the hum go away?

4) If step 2 solves the hum then we have to proceed with some more troubleshooting on your setup to remove the ground loop without using the cheater plug. Ground loops are a common issue and can be solved with some patience and being methodical. It's not a flaw with the equipment.

I had a hum about a month ago, when I moved my 600 to my back wall, and put my 2 350's up front. Doesn't make sense if everything is grounded to 1 location, meaning the main ground rod in the ground near the electrical entrance.

I removed the ground screw on the 600 and it worked fine. UNTIL, I just got Direct TV and have an HD receiver down in my theater. The HDMI cable is plugged into and HDMI in on my Denon and the power plugged into my Triplite surge/conditioner. Anyway, I have a worse hum than I did before. The dish and coax are grounded to the same rod, so not sure what is going on. The only way to stop the hum is to unplug my HD DirectV , or I've found if I unplug my front subs from the Denon Preouts it goes away as well.

I hate hums/ground loop issues. What gives.

I hear that a constant hum is apparent after many years of marriage, and divorce is the cure.

Interesting how getting rid of the screwy part fixes both issues.

And remember, Cam, only in Canada are camo-patterned, vertical blinds called draperies.

Canada? No. We are not much into the military theme. When Cam travels to Cuba that is a different story. Sorry, he won't cross over to the US.
