![]() ![]() Other preamps like the Audible Illusions Modulus 3A can have up to 30dB of gain. For instance, the PrimaLuna DiaLogue Premium has only 10dB of gain. This type of noise can be caused by a few different factors. You can add an amp with less power and have the idle noise go up. What counts is what is happening when the music plays. I remember back working at Rogersound Labs over 20 years ago, when we saw people do this we would laugh. Well, putting your ear up to the tweeter to listen for noise THAT WILL ALWAYS BE THERE and thinking it's a problem is even sillier! I will personally drive or fly out there and turn you over my knee and give you a spankin'. If you walk up and put your ear to the tweeter to look for hiss. maybe it's time to smoke a fattie one more time.Ģ. Imagine being 18 yrs old and smoking a joint and acting like this. don't ruin one of the few things that bring you joy by nutty-ing up. you will get freaked and won't quit until you find a situation where it IS audible, just to prove there is a problem. If you start to chase your own tail like a crazy dog. That is called the signal-to-noise ratio. Once the music is playing, it is not audible. Even if you turn the volume all the way down, and there is still some remaining hiss, it means nothing. Before going forward, you have to promise to remember these two major points:ġ. This is a question that will lead to people doing dumb things and getting freaked out. Talk to Lonnie and get a replacement A 100% properly functioning XPA amp is darn good, and should be very pleasing in all aspects.I have changed a component and idle hiss went up. That's a sure sign of something being wrong with the amp. And particularly if one or two channels are louder than the others. But it should be very quiet or completely inaudible from your seat. He'll take care of you if it really is a defective amp.Īgain, a very slight hiss IS normal. ![]() Just ask to speak with Lonnie Vaughn and deal with him right from the get go. Seems to be one guy named Vincent who causes all the problems. I know that Emotiva's customer service is less than stellar sometimes. If they are, then you have a couple of defective boards, and you should be firm with Emotiva until they send you a replacement. Try to discern if one or two of the channels are significantly louder than the others. Try connecting just one speaker, and connect that one speaker to each output on your Emotiva amp. That is NOT normal, and after finally getting a replacement from Emotiva, he now has a properly functioning XPA-5 that is silent at seating distance, and only produces a soft hiss that can only be heard if he's within a few inches of the speakers. But two of the channels produced an audible hiss that he could hear from his seat. Three of the channels produced a normal, very soft hiss that he could only make out from a few inches away. A forum member a few months back had a similar situation with his XPA-5. In actual seriousness, though, you might actually have a slightly defective amp. ![]() If I physically press my ear against my speakers' tweeters, I can make out an extremely soft hiss from my AT1805. #SPEAKER HISS HOW TO#I have also disconnected everything from the amp and just had the speakers connected, the hiss is still there so I know that its not coming from another component.ĭoes anyone have any suggestions on how to eliminate the hiss or is it just something I have to live with? I have a limited knowledge of electrical engineering, but I was thinking if I hooked up a resister in line with the speaker cable this would increase the resistance and make the speaker less sensitive? not sure how that would effect the components of the speaker though.Ĭlick to expand.Not quite DEAD silent, Acu. However with the rear speakers hooked up to only my receiver the problem still exists. With all of the speakers connected to the XPA-5 the distortion issue I was having with COD black ops 2 was almost completely eliminated. To solve this problem I just hooked the RS-52 back up to my receiver. When I put my ear to my center and tower speakers there is a hiss as well, however I cannot hear it from my listening position. #SPEAKER HISS MOVIE#My problem is that when I pause a movie or listen to 2Channel music, There is a Hiss coming from my RS-52ii which I can hear from my listening position. I hooked everything up and everything sounds great, Much more powerful, the speakers sounded much better than when connected to the SR5007. Hey all, I purchased an XPA-5 to power my home theater I was planning on running my fronts center and surrounds off of it and my rear surrounds off my reciever. ![]()
