Can you hear speaker hiss (when volume very low or no sound), is it normal or did I get a bad unit?

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.

Yes I have the same hissing sound on my unit too. Not too excited about it either. I am from Canada, and shipping it back and forth to the USA will be too much of a hassle and too expensive to do, so I'll just keep it as is. :-(

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.

Not a bad unit Jay. It picks up interference from the internal electronics and power cord. Did you put the ferrite choke on the power cord? I am not too impressed with this unit. For 1000w witch I doubt and the money I would not buy it again. Ken

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.

As Jeffrey...Yes, I have the same hissing sound on my unit too... I am from Canada, and I cannot shipping it back to the USA since It will be too expensive to do so, so I'll just keep it as is.

Speaker hiss no but if u have a cd on at low volume that happens sometimes in some radios don't worry about it

I purchased this unit and from the start the sound quality was very poor. The speaker vibrated on low base. I returned the unit for a full refund. I hope you have better luck with your unit. Have a great day.

Check everything:1. Computer volume still correct?2. Amp volume ok?3. EQ not messed with?4. Headphone cable ok?5. Cable to computer ok?6. Tube seated?Check the obvious first... Otherwise, I have no idea, mine sounds great!

Nothing I tried that and got nothing. .i even bought a y splitter to run 2 sets of speakers and got this loud humming sound!!

I have two units. One is dead silent in the idle mode, the other has a barely detectable white noise. Try double-clicling on the Play/Stop button to change into another audio mode, such as for speech.

Kevin, a few things come to mind. One could be a bad sound card in the audio device. Another could be a bad set of audio cables at the speaker location. Hard to say.Eric C

Try reducing the output volume. I have to keep mine fairly low. Takes some tweaking

I also agree with the checking the cables but here's another thing to look at. This kind of interference or feedback only happens to me when I don't turn everything on in the right order. That is computer on, Pioneer DDJ-SR on, open Serato, turn on subwoofer (passing the Eris 8's via the sub (Temblor 10), the Eris 8's on. No feedback, although there is very minute hissing. If I turn the speakers on first all kinds of hissing and feedback. That's been my experience. Not sure how you're using these but Hope that points you towards resolution.

At low volumes it is not very noticable... but if you crank it up then turn off the source of the audio (like turning off your tv) leaving the sound bar on...then the hum is bad.

I got some feedback when using the amplifier in a small room and at high volume. Try lower volume or any close wall at front. If feedback is always present, maybe is defective.

I have never had a hissing noise from my unit. The only sound from my unit is the voice giving me directions.

I am going through the same problem that you have and listen to the same type of music (classical music and folk music) and have been told the same thing. I have a friend who has the same system as me and I used one of his speakers in place of my one malfunctioning one and I don't hear the hiss anymore. I'm in the middle of a troubleshooting argument with their staff right now, and I fear that they would be wasting my time and theirs in insisting it is the amp in the back.

I have had this unit for almost a year in live application and have not experienced any unusual noise or hiss. I am sure if the gain structure is wrong any unit could have the potential for noise. hope that's what you wanted to hear

the hum level on my pioneer speakers is very low. you can hear a faint static sound if you put your ear right up to the speaker, but it is not intrusive. on the other hand my friend also has these exact speakers, and he sometimes noticed a much louder static noise on his speakers, much like a guitar amp sometimes picks up radio/ cell phone frequencies and those noises come through the speakers. but I think that happened only because somehow his speakers were near some sort of frequency. so it's more of a variable problem, not something that always happens. hope this helps. :)

I have two sets of this particular speaker system. Mine work great!Hmmm, don't tell anyone okay? I did a dumb thing and my speakers wouldn't work! So I order new ones...same brand.Look at the bottom part of your monitor (screen). There is a little icon for "speaker" on the lower right side of your computer screen.By accident, I turned my speakers off. I thought there was something wrong with my old Logitech speakers. So? I ordered more. Guess what! There was absolutely nothing wrong with my old speakers BUT! These are much more clear and the volume is louder.I couldn't be happier.

There is no hiss on background when play it loud as long as material recorded properly. I use this amp to drive my KEF Iq10 very loud but not to overload, it is so quiet during soft passages. Hope this is what you're looking for.

That is what I had awhile back. You will hear a different. There is no more hissing or noise in the background. The copper wall in the card that divide the circuits is a plus to prevent the noise and hissing.
