FilziSH Posted February 18, 2019 Share Posted February 18, 2019 Is it normal that a small hum comes from the device itself? I know that HX is heating up and this is normal, but nothing is said about the hum anywhere. Quote Link to comment Share on other sites More sharing options...

phil_m Posted February 18, 2019 Share Posted February 18, 2019 Well, it depends... Are you talking about 60-cycle hum? Or is it more of a hiss? If you have a high gain amp model selected, there will be some noise. Also, do you have the Stomp connected to a computer via USB? If you're connected to an amp at the same time, this can sometimes cause some noise. I guess I need a little more info to say either way.

spikey Posted February 19, 2019 Share Posted February 19, 2019 when you say hum from the device, you mean not from the speakers/headphones but the unit itself is humming? Do you recognize the tune? I'm sorry that was mean... Funny, but mean... ; ) Quote Link to comment Share on other sites More sharing options...

Exactly. It's very weak, almost inaudible. But it is. If you bring your ear close to the HX it sounds like hiss from speakers or tape hiss Quote Link to comment Share on other sites More sharing options...

The device heats up, but I don't know which heating temperature is considered as normal. I wouldn't say that "very" Quote Link to comment Share on other sites More sharing options...
phil_m Posted February 19, 2019 Share Posted February 19, 2019 I can't really think of what would be causing a hissing or humming to come from inside the unit itself... I mean, it's possible that there would be some gases expanding inside, but I can't imagine that there would be near enough pressure that you would hear anything like that. I mean, it could possibly be the coils from the relays buzzing, but that seems somewhat unlikely... I don't know... Open a support ticket, I guess.

FilziSH Posted February 22, 2019 Author Share Posted February 22, 2019 I made a video. Sound was recorded separately on a recorder with a high input level, because through the phone mic this hiss cannot be heard. Also I use hard limiting, so keep in mind, in fact the sound is much quieter https://youtu.be/k1s76lzY4bE Quote Link to comment Share on other sites More sharing options...
FilziSH Posted February 23, 2019 Author Share Posted February 23, 2019 OK, I have response from support : Quote That amount of high frequency artifact, or 'white noise' is completely normal for the operation of the HX Stomp I guess the question is closed :) Quote Link to comment Share on other sites More sharing options...
pep_mirall3s Posted January 8, 2020 Share Posted January 8, 2020 Hi guys, I just bought an hx stomp and I am so happy with the sounds I can get out of it. I am using it with studio monitors (M-audio bx5 d3) and it works well. The only problem that I have is that when I plug the stomp to my computer via usb it makes noise. Since it only makes that noise when plugged with usb I know thr cables or the monitors are not the problem. If anyone knows how to fix it let me know cause it is a little bit annoying. Thanks in advanced. Quote Link to comment Share on other sites More sharing options...

Thanks in advanced. Is the noise there all the time or just when you touch the capacitive foot switches or other parts of the Stomp? What kind of noise it is? Digital static, analog hiss, buzz (120 hz), hum (60 hz)? FWIW... When connected via USB my Helix makes noise (I'd say digital static) when I touch the switches... and maybe some other parts - but it doesn't make any noise when it is just being used. I don't know if that is normal or not, I'm not concerned about it in any way. Fixes? Things to try? Make sure you are not plugged into a USB hub.... this would include the front USB ports on "most" computers. Try a different USB Port on the computer Try a different USB cable.... preferably ones with ferrite chokes. Ferrite chokes are the "bulge" before the end of the cable... their purpose is to eliminate/lower electromagnetic and radio interference. Many (if not most) USB cables are made with those. Try re-positioning the stomp... Quote Link to comment Share on other sites More sharing options...

The unbalanced cables create a ground loop when connected via usb. Can it be that? Quote Link to comment Share on other sites More sharing options...

Well, unless you already own those cables that is the most expensive option to try.... I never start with the most expensive option :) Quote Link to comment Share on other sites More sharing options...
soblivion Posted January 9, 2020 Share Posted January 9, 2020 If, by chance, the computer is a laptop unplug the laptop from power and allow it to run off the battery. If the noise goes away then it's likely a ground loop. This is a fairly common problem with this type of equipment. Unplugging your laptop isn't really a solution, just a trouble shooting step. There's a lot of information out there on dealing with ground loops. I had a similar issue, unfortunately I don't remember what I did to fix it. I believe I plugged one of the devices in the system to a different power outlet. 1 Quote Link to comment Share on other sites More sharing options...
