coachz Posted March 15, 2022 Share Posted March 15, 2022 I have HX edit setup using the USB cable and the noise from the computer makes it unusable. Do you guys have any suggestions ? I also tried connecting a MIO midi device into the 5 pin DINs but HX edit didn't see it. Thanks for any suggestions as HX Edit is important to me. Stomp XL is setup in 4CB with Marshall DSL40CR.

spaceatl Posted March 15, 2022 Share Posted March 15, 2022 Start with isolating your power. I used a Tripp Lite LCR2400 for my main rig and an LC1200 for my home studio....I don't have ground loops and I don't have those money pit hum elminators...A conditioner is not enough...You have to have a transformer on your power to eliminate ground loops...Easiest way to do that is to get an Automative Voltage Regulator. You get stable voltage, conditioning and isolation....Usually it's as simple as putting the computer on the house power and all of your audio gear on the transformer. Anyhoo, that's how pros do it....Good luck. Quote Link to comment Share on other sites More sharing options...

No isolation unless on the battery and disconnected from house power completely...Would need to know the brand and model to know that.

coachz Posted March 15, 2022 Author Share Posted March 15, 2022 Yeah you're totally right. Mine won't have any conditioning, just common ground. So what does your have ? Separate transformers on every tap ? Quote Link to comment Share on other sites More sharing options...

So what does your have ? Separate transformers on every tap ? multitap transformer....Tripp Lites are about +-5% or so as there are just three...Nominal, Hi and Lo...Furman AR15 is a bit more precise and uses a toroidal transformer with more taps (6 iirc)...So they stay within about +-1 v....Isolation is the same with any transformer....You can still have loops within your rig, but once your rig is isolated, that's just a shield lift here and there and you are done....Very easy to run those down when the rig is isolated...A whole lot harder when refrigerators and other motors in the house circuit are not isolated away from the audio gear from and input power perspective. Basically, the clicks in the Tripp Lite stuff are a bit louder than the Furman....Furmans are great, but you will pay a lot for one of those...I used to tour with an AR15, but since I don't tour anymore and I am paying for it now, I use Tripp Lite...Much more cost effective for me...

theElevators Posted March 15, 2022 Share Posted March 15, 2022 Makes what unusable? When not using the Helix the USB cable left in your computer makes too much noise? -- I have that! If I have sound coming out of the headphone jack of my laptop, I have to un-plug the USB cable. Otherwise it starts introducing noise... But not right away after about 5--10 minutes.

coachz Posted March 15, 2022 Author Share Posted March 15, 2022 No my problem is WHEN the USB is connected with my computer, the stomp gets crazy hi frequency noise. Quote Link to comment Share on other sites More sharing options...
coachz Posted March 16, 2022 Author Share Posted March 16, 2022 I loaded hx edit on my laptop and the noise is gone when connected over USB to the stomp xl even with the laptop power supply plugged in so at least that works. Quote Link to comment Share on other sites More sharing options...
