Sorry I listed my surge protector as an MTS 100. It is an MTS 1000. It has developed a very loud humm. Is there anything I can do to eliminate the humm?

sounds like it has a problem, there should be no noise coming from unit, contact manufacturer or place of purchase.

I had the same exact issue and from my research it appears as if the hmmm signifies that the unit is not longer functioning properly and need to be replaced. Sorry my answer probably isn't as technical as you would like but that's what it boils down to.

First, contact the manufacturer for a solution. If that doesn't work, find yourself a piece of non-flammable foam and put in the case or on the bottom. I have had mine for quite a while now and had no problems. Must note that we have very dirty electricity here.

TakkyMonster may have an international adapter surge Protector. This Monster product I purchased is designed for US 110vac home use. It has great features for this use.

Mine is on as well. I expect Steakman is correct and this just means surge protection is active.

Don't know.-- Added my own meter lights and replaced an internally shorted transformer with a bigger and better one out of the junk box. Also put higher capacity pass transistors on my second unit. Yeah the fan gets growly; other than that they both work.

I had the same problem, I had to move it, it was getting AC noise from the wall outlet, make sure all your power cords are away from it. (good luck)

Could be a defective unit. Mine will sometimes make a very slight hum (ear right next to the unit) but even when I'm lying in bed sleeping other than the reassuring click that it turned on, I can't hear the hum. I also am only drawing... ~11A on the heaviest circuit, if you're pulling more than that it could explain a louder noise

You're experiencing ground loop hum. Try using batteries only. If you still here loud hums, send it in for repair.

I find the UPS or surge strip is usually my problem not the PC but either way it should help. I have my UPS plugged into one and that cleared up my main problem. Any type of surge protector appears to weaken the signal.

Assuming the outlet is working, it sounds like your base unit is shot. I've had a couple of these phones now and they are very sensitive to power surges. I put my current unit on a surge protector and it's lasted several years now.

The reason you are hearing the hum is because your transformer plates are slightly loose. The metal plates in the core are laminated and can become separated, you may be able to reduce or eliminate the hum by painting a varnish or shelac onto the core and letting it "soak in". I would suggest several thin coats to do the job. The metal core itself can be loose and vibrate as a whole too so you may need to seal that up the plastic bobbin that the copper windings are wound on. Otherwise if all else fails this unit is quiet, at least the one I got is. You may also try insulating between the transformer and the joist if yours is mountable that way. Hope that helps.

Looking at the description, it says it's a surge protectory. However, I was only using it for the adaptor issues.

Tripp Lite's website specs say: "UL1449 let through rating 400, 500, 500", so if my understanding of surge protector-related stuff is accurate, this little unit is probably not the best choice for sensitive and/or expensive electronics like computers, TVs, etc... I use mine for cordless phone charging bases and microwave ovens.

what's the certification on your power supply? (80+ bronze, silver, gold, etc..), 750 should be more than enough by far, but if the power supply unit is sketchy then it could be not performing anywhere near what it theoretically should be. also, anti-surge could be related to your electrical setup, what do you have the tower plugged into? does it trip the circuit breaker or does only your tower shut off?

Hey Karen, The underside of the product reads that it is a "Surge Protective Device 50E8 A414657H1". I am not quite sure if this helps.Shane

It all depends on how long the run is and if it will be going near any electrical cables. Electrical cables and long cable runs often cause annoying humms. A good quality cable like this one should alleviate those problems. If it is still an issue, mind my asking what type and model your AV Recever is?

I didn't have one. Sounds more like a power strip to me. I had the same equipment, each on its own adapter, outlet. I didn't have surge protection, it an was fine but could have been luck of the draw. If you want added peace of mind, then get it.

I made some search and find an article which might answer your question. I hope it helps! http://thewirecutter.com/reviews/best-surge-protector/
