Speaker hiss1/10/2023 Point is, when I hear reviews that talk about a noticeable hiss ,like I hear about on the Adam A7X, I shy away but not because I don't think the hiss will be bearable when I first get them, like they were with my JBL 305's new, but I'm concerned at how much worse they will get over time. He was a bit dumbfounded by the hiss, because contrary to popular belief, Class D amps are actually very quiet so the next logical thing to look for was noisy pots (volume control) but that wasn't it so we think it might be the op amps JBL used in these that just degraded over time but we're both so busy he hasn't had time to crack them open and I still need to use them for mixing so I deal with it for now. People come to him all the time with vintage gear. I work in the A/V industry and am lucky enough to have access to a coworker who has done repairs for every type of audio and video equipment you can think of for the last 30 years. When I first got them the hiss was only audible if you put your ear to them but in the last year, I think I'm going on 5 years now with the 305's the hiss has gotten worse. I confess to keeping my current hissy monitors off almost all the time for this reason.Ĭlick to expand.My 305(first gen) also hiss really bad now and the main reason I'm looking for something different. Or maybe the answer is just to suck it up and get used to it. Maybe the answer is passive monitors? That makes the shopping more complicated, but I'd appreciate any pointers there as well. So I was hoping I could get some pointers about where to look. Using the same amp and preamp, and the volume set to. ![]() There are no vents and no bulging on either PTH cap, and besides the color & specs, they resemble the one pictured below. Usually if you are in a teeny room and sit close to the speaker, or if you have high sensitivity speakers. Some digging online suggests that capacitors can hiss, piezoelectrically, but that seems limited to ceramic caps, not electrolytic ones. The easy answer is that I need to find some showroom with everything set up and listen for myself, but at least in the case of Adam dealers, the nearest one is a non-trivial drive. The rest are SMD, and the PTH caps are held down by white adhesive. I've also taken a look at Dynaudio BM5 mk iiis (at the other end of my price range), and they too are quite prone to hiss. As best I can tell from some googling around, they are rather prone to a white noise hiss. Given some convincing, my budget is up to about $1500, which I admit is influenced by the cost of Adam A7Xs. It's just a very quiet room and I'm annoyed by hissing noise when they're not actively playing sound. Hum would be even worse, though the monitors currently in that space have no hum. I have a sound clip here of me sitting far and then moving close to the tweeter, down to the speaker and then back up to the tweeter so you see what I mean.So I'm looking for new studio monitors, but with a particular quirk: I really hate the amp hiss/white noise that many (most?) active monitors have, even without inputs. If you are hearing sound while the speakers are not playing audio, it is normal to hear some white noise or a low hiss with an active speaker as the inputs. You could try removing the DAC entirely and see if that helps. I wouldnt be surprised if there was no hiss. Make sure your DAC and speakers share the same ground. To test this, try using a digital input from your DVD player for instance, and pause the DVD. There are two main sources, difference in resistance to ground, and amplifier distortion. Make sure your DAC and speakers share the same ground. ![]() We keep beating this up and because we tech types like to solve issues, Ill also look into it. There are two main sources, difference in resistance to ground, and amplifier distortion. Post by ShowMaster » Mon 4:53 pm Jsha, did you get your board yet I unplugged my XJT module and no difference in the hiss were discussing, I dont think RF is the cause. It could also be a much quieter, yet equally annoying buzz or hum that you only. I have balanced cables so should I be getting any noise like this? It is measured in dB, called signal to noise ratio. It is measured in dB, called signal to noise ratio. The most common manifestations are a loud buzz or hum coming through the speakers, or scrolling bands on a TV screen. I didn't really notice this before and wonder if something has suddenly happened to them? Is this normal? At sitting position you can notice that it's there but obviously as you get closer to the tweeter it's much more obvious. I recently purchased the Yamaha HS7 Monitors and I've noticed some white noise/hiss coming out of the tweeters and a hum coming from below the speaker. Couldn't really work out where to put this.
