Is it normal for speakers to hiss

It's actually pretty normal for a receiver to produce a hiss from the speakers when there is nothing at all attached, but then go silent as soon as a source device is connected and powered on. If this is what happens, then we know that the problem lies either with the specific input that you are using for your Dish box, or the hiss is coming from the Dish box itself. So, naturally, try connecting that CD player that you just used to test the receiver to the input that you would normally use for your Dish box.

Set the receiver to "look" for the input that you are using and see what happens with the hiss. If you can get the input to work without a hiss, then we know that the hiss is coming from the Dish box itself. Hope that helps! I think as long as you can only hear the hiss noise with your ears against the tweeters, it's okay and normal.

But on my friend Tim's Linkwitz Orion speaker system, I could hear a slight hiss with my ears against the drivers. Ok i did a little trouble shooting With everything unhooked from the receiver but the speakers i went through all the inputs selections It was less faint when i selected the THX modes.

With everything hooked back up Last edited: Mar 11, Sounds Good said:. I think I made a breakthrough I guess until I get a subwoofer ill just put up with the hiss and use Dynamic EQ for more range I think here's what's happening, Dynamic EQ boosts frequencies we're less sensitive to, in order to give a lifelike tonal balance at lower volumes.

However noise is also boosted. If at db we hear noise, and at 85db we don't, then a 15db boost of certain frequencies, even at a usual volume of 85db, might make them audible. GranteedEV said:. Please discuss more Hiss in speakers normally comes from a bad board or a ground loop. My only experiences with real hiss came from a bad board in the receiver.

A ground loop normally had a different kind of hiss. These can only work correctly when Audyssey has been run. If it hisses, it's possible that Audyssey needs to be run again- maybe because there was some kind of noise while it was running the previous time. You must log in or register to reply here.

Should I try a different outlet? I am in an apartment so only have one or two places to put everything. Any help would be greatly appreciated. Edit Delete. Don't lose sleep. This is normal and very common. It's the noise floor of your amp and no power conditioner or magic power cable will alleviate it. No this is not normal anymore.

I just checked with my own P3ESRs driven by an old refurbished Quad and just a volume control : nothing, absolutely nothing, no mains hum and no noise. It might be different if you are a young girl, of course, since they have better high frequency hearing I will have to ask my daughter.

With very efficient speakers you might just hear something, but not with inefficient ones like these. Cables do not make any difference in this respect, so they are also out. And since you also hear it when you have disconnected your sources, it is not those either. So it is the amplifier in one way or another. Do you hear it on every input or only on some? I hear a slight hiss from my phono preamp tube.

If you don't hear anything from your listening position why bother with it? Have db 1 watt loudspeakers running and no noise so while a bit of hiss can be normal in some systems its possible to not have any. Many point to tube amps as having noise but I have found that some SS amplifiers can be even more so.

One could argue this is an indication of a suboptimal design by the manufacturer. This statement is incorrect. With nearly any integrated amplifier a hiss will be heard on that speaker. But it is of no consequence as others have pointed out; I've yet to meet any audiophile that listened to their speakers from only a couple of inches.

All brands and models of amplifiers vary, as will individual examples of each. I asked my young son: he hears a faint hiss at very close range. They almost all do. But Can't hear a thing if my ear is few inches away. The hiss should only get so "audible" and then cranking the volume further clockwise should NOT increase the volume of the hiss. Something else to try. RCA shorting plugs on the unused inputs of the amp. And yet something else If your speakers are emanating a low hum or a soft hiss, it might be a regular occurrence.

A soft self-generated hissing noise is so common on active speakers that some manufacturers publish the level of self-generated noise for their products. For instance, Genelec says that their a Studio Monitor Dark Grey generates less than five decibels of noise. Several users also note the hissing when you deliberately listen for it and when you get too close to your speakers. But there are more reasons why active speakers hiss, and some seem to cause more of an audible problem than the hiss most powered speakers make by themselves.

There are many reasons why powered speakers hum or hiss. The most obvious is the noise that your audio signal has. Your speakers are designed to reproduce audio signals.

However, it can cause a ground loop, which happens when you have two or more pieces of equipment plugged into different alternating current power supplies. When these cables have shielding that is connected to the ground, then the ground loop happens. What occurs is that this setup will create an electromagnetic induction field that will attract noise into your speakers. Aside from ground loops, another source of hissing or humming on your speakers is AC line noise.

The interference can come from blenders, hairdryers, and anything with a motor. There are several reasons why wiring and wires can be a source of the noise. For one, poor-quality cables can introduce noise. There are several cheaper cable options that also do a good job.
