Static Noise

So I got an Ek-50 less than a week ago and noticed a static noise coming from the built-in effects. I know it's not the speakers since I've used them to listen to external audio through aux chord, plus I used headphones and confirmed the noise persists while using them. That's why I think it's coming from the effects themselves. I haven't found anyone addressing such issues so I'd appreciate some input. Thanks.

You could try a Factory Restore/Reset, John, and see if that cures the problem?

Hello Mitzie, thank you for your response. I've tried it but it's all the same. One thing I've realized is that it gets much more noticeable when I have effects active on a preset. For example, I put a small reverb and a slow rotary effect into a grand piano preset and this causes the noise to be significantly louder... I've also tried different power outlets but it didn't help.

Is there anything connected to the Audio In? Is the EK50 near a source of interference? e.g. cellphone, WiFi transceiver (router or laptop).

No, nothing. I disconnected everything except for the power cable and I've also tested while not having any of those devices around.

It sounds like you may have purchased a faulty unit. I would return it for another one. Sometimes, these types of things happen

Or, just to make sure it's not a ground loop effect, disconnect it from the mains and run it using batteries.

With some other equipment of mine I had to do the same to minimize interference.

I have had my EK-50 U less than a week. I found a persistent static - popping sound when displaying only one particular effect. #38 "St.AnlgRecd". Its not a big deal, but I noticed I'm not the only one to experience this type of issue.
