Poor quality wiring and bad connections can. 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. When seeking to answer the question, What Causes Speaker Hum & Hiss Its important to check your cables and wires. I have aconstant hiss sound through my speakers when the volume is turned down.
#SPEAKER HISS CRACK#
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. Constant Speaker Hiss troubleshooting/ advice 03-24-2014, 10:03 AM. 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. 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. 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 too have self powered computer amp costing (H.K.) and it too produced hiss. May be you should return it if produces the hiss even without being used by computer (CDP or MP3 player). They added these huge side speakers when 4th Mix came out.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 getting hiss from CD/MP3 lineout (while no other thing is connected or powered up), Im guessing it is the speaker. Side note: you want an arcade game with really loud hiss? Try Konami's Guitar Freaks rhythm game. When youre more than a few feet away from your speakers you shouldnt hear any noise, right Some folks are more demanding than that, if they put their ear. In this case.the game's audio amp is *probably* (again, my speculation here) running at max volume, and the TA7630P is simply controlling volume on the line-level signal. Probably has to do with the fact that Motion+ is more powerful and has tweeters.
#SPEAKER HISS BLUETOOTH#
After that I have checked my Soundcore Boost bluetooth speaker and it seems it has the same type of noise, but is audible only when I put the ear to less then 20cm. The amp(s) could be running at their loudest possible setting, kind of like when you crank your home speaker system to max volume, you'll probably hear a hiss, but you don't run your speakers at max volume normally, so you don't hear the hiss. Speaker is not connected to charger, so this is not transformer noise. But this chip could possibly be causing the hiss. Lots of fancy features for an 8-bit game.
There's a TA7630P which controls volume/balance/treble/bass as you can see those individual adjustments on your board. much more complex than your average 8-bit arcade board of the same era. The analog sound circuitry as you can see is quite complex. You could try removing the DAC entirely and see if that helps. Make sure your DAC and speakers share the same ground. There are two main sources, difference in resistance to ground, and amplifier distortion. Here's a possible explanation, but I could totally be talking out of my ass here so take this with a grain of salt: It is measured in dB, called signal to noise ratio. I own several System 1 boards and they all have this hiss.
