My 823LM works fine, but has a faint humm from the unit. You need to really listen or get close to it to hear. Is this normal?

You know I had to go and check! However, I have an 828LM and no hum whatsoever. Have you unplugged (the replugged) the unit and tested it away from other equipment for this humming noise?

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.

No, I don't have that problem. I never noticed a fan running until I read this email. Now, I can hear a slight hum occasionally. But nothing you should ever notice. Yours is not right.

Thank you! I finally solved the hum problem by plugging the iMic into "Line Out" on my amplifier instead of directly into my turntable. The hum disappeared! Hope you got your hum solved, too.Maria

No, I have not had that problem. The only problem is an occasional hum in the speakers.

I don't think I've heard any on mine. If you are hearing the hum while using the RCA jacks then maybe trying unplugging it from USB/have the turntable and speakers on separate outlets. If you are hearing it over USB then maybe just try the same isolation but between the computer and the turntable.

The unit gives off a hum that is hear our 10 feet away. That is when the unit is running. I have found that they tend to break with in a month or two of purchase. I have had one that lasted 3 years though.

Ours makes a small cyclic hum. You can hear it. It doesn't bother me, but everyone has different tolerances.

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.

I use it to record through, and can say I have no evidence of a hum. A hum is usually a sign of a ground loop, so I would suggest trying an decoupler (hum buster) if it persists when connecting your devices.

I get the same thing from a Vizio. You could probably get an in-line noise filter to fix that problem but the hum mine isn't loud enough to bother me so I haven't done much.

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.

I have a 2 week old Sound Bar with a similar issue as well. It emits a high-pitch (electrical) whine on stand-by. No firmware updates or results in Google yet. Just your post. May call Samsung before I return it to Best Buy.

I am getting the same thing. It is a buzzing/loud humming noise. Anybody know if this is a defect or if something else can be creating this?

interference of some kind or the speaker wires aren't connected correctly, or may be loose. I hooked ours up the way the amp I replaced was hooked up and the Pyle didn't work. Turned out to be much simpler. The second configuration I tried hummed and the sound was staticy. I think I have all 6 of our PAs combined to 1 set of wires and on one speaker connection and it has worked perfectly all summer. Hope that helps.

I not totally sure, but I know if there is humming you have some electrical interference. The cables are possibly too close to the conduit in the walls or some other issue. I've had no problems with my setup, but when I turn my microwave on the sub hums. Not a big deal for me since it's not used much. So it's worth a try, if not return it.

Yes this is a problem I am having with my new system as well, same make and model. I ordered a replacement the other day. Seems to be a problem with the receiver, I wrote about it in my review.

Sounds like you might have a bad one. I have 6 of these....no chirping since I installed them 6 months ago.
