Maybe off topic. If I disc cable at coupler bad hum stops. I know I should find hum, tried hard but can't. Can I solve with this switch? 150 char! :(

Don't know I wouldn't think so. Check different Cables they are not all the same. The only set I had that hummed was a philco 25" 17-18 yrs. back. Did it a few weeks after I got it. got rid of it. also check the source and maybe different couplers?

Mine has a slight hum. Some kind of ground loop, I guess. I'm using a 3-pin to 2-pin adaptor on the power cord--the hum is much worse without it. I've tried both the balanced and phone plug inputs (with RCA adaptors)... no difference. I haven't tried breaking the ground on one of the input cables yet.

I use a beringer preamp picked up for $40, the hum went away, it has to do with noisy power from the audio source, not the amplifier.

I listened really closely (ear right next to the switch) and too can hear a very faint electrical hum (maybe 60 kHz?). But from any reasonable distance, I can't hear it at all.

If you're 100% sure it's not the source, then yes. I don't have hum unless I am on high volume but I have had a lot of source hum from my sound card. So check that out before shipping it off.

I use a 35 ft. VGA/ audio cable from my PC with a PC/TV tuner, using it as a DVR with Windows Media center to my Big Screen and also use my Monitor with a VGA Powered splitter. Using a powered splitter because with out it I had lines on the TV, the powered splitter took care of it, but I also have a hum or feed back sound, can't explain it. It may be the same sound you have, if you get a answer to your question please let me know at DWB@socal.rr.com, Thanks Don

I had surround sound and two of the 7 speakers hummed when I put the Direct TV HD in "pause." To fix this problem go to the Direct TV remote, setup, settings, audio, and turn "on" dolby digital. Mine was off and caused the hum!

Thanks very much to those who offered suggestions. Everything was fine with the wiring. A phone call to a Sony tech resolved the problem, which was found to be my selection of HDMI Passthrough to "ON". As such, the receiver remained partially powered in Standby and resulted in the hum. Re-selecting HDMI Passthrough to "OFF" cured the problem.

I've successfully plugged both into a power source without humming. However, I suspect it may vary from power source to power source, and maybe even from unit to unit. Your milage, it might vary.

It is a bad unit. I had to send mine back.I just read the answer below mine, did you put the ferrite choke on the unit on the power cord? Hello! This unit should be ready to go out of the box. That hiss or hum could be heard over spoken words too. If you can send it back.

How did you connect the wiring? Did you use butt connectors, solder, tape? I have never encountered static other than for the split second when you switch the device on and it interferes with 87.9. Then it goes quiet. You might check the gain setting on the device with a flathead screwdriver. Mine is turned up all the way.

Have you tried switching your cable? I've never gotten any humming when playing this, either through a tube or solid state amp.

You have a ground loop somewhere. These can be hard to find and fix. I would do some reading on it. Musicians are often very familiar with this problem. Often times it's as simple as making sure that the two devices sharing the circuit (for example, in an audio circuit like this, the computer generating the audio signal and the speakers outputting it) are on the same AC outlet -- often times plugging into different AC outlets can introduce a ground loop. I've had some luck with ground loop isolators and filters. Amazon sells a number of these. You'd want one that's targeted toward your specific cable type. I've also had some success upgrading my audio cables. In one particularly annoying case I finally isolated the problem to a specific AC/DC adapter. When I replaced that with an equivalent, the problem went away. Diagnosis can be tedious. For that last one, I repeatedly unplugged everything then started connecting things one at a time until I found the pattern where the AC/DC adapter was the offender. I had another one that turned out to be a coax cable TV cable -- I have a TV as one of my sources on this device. A coax ground isolator at the cable source took the problem away immediately (I was surprised at how easy that one was). In addition to the specific isolators/filters you plug cords into, you can also get small suppression devices (RF suppression) that snap on the existing cords. I haven't had much luck with those for my specific problems. When you buy a cable with those cylindrical bulges at the ends, that's often the same sort of thing built into the cord.

Yup, had the same exact problem. I thought it was the speaker to speaker cables, the Coax or Toslink cable and then my computers sound card but it wasn't. It drove me nuts. If it's still under warranty, send it back and have them fix it.

Radio shack also sells ground loop.isolators or you can build your own from a 1:1 transformer this should also fix the hum as well.

All of what has already been said, AND, the headphone link is very noisy. Mine is anyway. Buzzes...hums... Same with two different inputs, two different power sources, no matter where it is placed. It's not an enviromentally induced noise...it's the converter.
