There is a slight hissing sound even when I turn off the power on the puck. Goes away only when I unplug the speakers from the power. Is this normal?

I have an unbearable and fairly loud background humm when the unit is on and not streaming ~ That's why I suggested they offer a remote on and off unit. However, my unit does not hiss or hum after the puck is turned off. I guess try turning the volume down first? Good Luck.

This is not normal. I believe the hissing sound in your system originates from a cross talk of the audio in cable (that connects between your Bose unit to your PC) or your power source. Try the following : Re-route the audio cable (avoid running the cable parallel to a power line) which is the easiest, or try using a power converter/stabilizer. Before you invest in a power stabilizer, unplug the audio input from your PC and crank up the volume gradually. If there is no noise, then your power line is "clean". If you plug in the audio cable back to the PC and the hissing sound re-appear, the source could be the PC or the audio cable cross talk, or the poor earthing of the chassis of your PC.

no it is not normal. I get the hissing sound until i turn off the puck(i.e. I touch it). The hissing with power on appears to happen with most computers and speakers, until the speakers are turned off.

Does the hissing noise occur solely on that Android device ? If the answer is no then you likely have a defective unit.

Lucy, I found the source of my hum. I have Direct TV HD. I found that going into the menu settings/Audio/Sound Effects and turning that option off, I was able to rid myself of the annoying hum. The option has something to do with keeping the audio settings from channel to channel, while it is changing you hear dead air except for the hum. Nice and quit now. Love this receiver! Larry

Hissing may be water inside the innards where it shouln't be. I would return it for an exchange if I were you. I hope you kept the packaging!!!! Call them first to tell them you are sending it back. This device should not make hissing sounds--loud motor noise seems to be the norm, though! --SuAnn

It sounds like you are getting FM noise coming in. This can be from the AC wiring in your house or from the speaker wire and since you replaced your speaker wire I would suggest trying a noise supressing surge protector of some sort. Monster Cable makes some great ones for that they are rated in what they call there clean power stage Monster MP PRO 800 with Clean Power Stage 1, Surge Protection, and 8 Color-Coded Outlets High Performance Pro PowerCenter

When mine was first installed, my electrician said I would hear some noises (something like a popping noise) after the unit shuts off and that would be normal. I'm not sure why. I've had mine installed for over 7 months and have not had any issues with it. I don't know for sure if it no longer makes the noise, or if it stops after a time.

Your source is doing that. Try plugging it in a different device. Hiss gone, guaranteed. (Late answer, but might help future inquirers).

This is normal. You should not hear any sound at all when just the ionizer is on, only when you turn the actual fan on.

Hi Kevin, I have experienced this noise. I bought it brand new and returned and exchanged it and the second television did this as well. You can read my comment on the comments page. Did you resolve this problem? CJ

The best thing to do is to try using a Monster Power Stage 2 (or better) line conditioner. For higher end audio systems, sometimes you get that hiss, so you eliminate the hiss by using a line conditioner. It's definitely worth a try.

As I do not own any DVD Audio discs, I am not certain, but do I remember hearing something to that effect a while back. A good place to look/ask the question would be on the AVS forum. Those folks in there will definitely know. Seek out the owners thread for the unit, the answer is probably somewhere in there.

In my setup there is no hiss or background buzzing in the background. I can have the volume knob at any volume setting and its dead silent with music off. The hissing and external noise might also be coming from your sound card, if your using onboard sound. I have my emotiva plugged into a Sound blaster Z gaming sound card. Hope this help answer your question.

I assume that your problem is related to the RCA audio output. I never experienced the problem you are having. My system switches between hdmi inputs from a comcast hdmi box, an inexpensive blu ray disc player, and an apple mac book pro. I did notice that that the inexpensive blu ray disc player hdmi connection to the switch and then via the analog audio interface to my audio mixer system caused a speaker hiss which I didn't get with my other components. I rewired my system to have the blu ray disc's audio go directly to my audio mixer system and that fixed the speaker hiss problem.

I had no hiss, but check inside the bottom of the speaker I did have a piece of plastic wrap packed inside that caused a noise. But once I removed it, it was fine.

My TV does not do that so I do not think it is normal. The only issue I have is the sound bar turns off while the TV is still on and I have to turn it back on.

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.
