please help! preenfm2, distortion noise on pure sine wave tone
« on: September 17, 2019, 11:08:23 PM »
hello everyone, i just bought a preenfm2 from a second hand place, it seems pretty clean and the guy who sold it didn't use it much, but i've been having some distorted frequency on all the sounds, doesn't matter the volume, it's all the time there.
anyone have an idea if it's possible to remove this noise?
i've seen that there have been issues with the yellow oled with high pitch frequency, i'm not annoyed from that, i just want to be able to get a clean sine wave
i've attached an audio file
