Stage 3 LED display buzzing?

Postby NordNerd431 » 15 Apr 2018, 03:51

Anybody notice a buzzing noise, seemingly coming from the LED displays of the Stage 3? I just got my Stage 3 88 today, and noticed it as soon as I took off my headphones after playing it for about 30 minutes. If normal, I could certainly get used to it, but not sure if it is a sign that something is not right. Thanks in advance for your input.

Are you sure it isn't just the power supply? How loud is it?

It probably isn't anything to worry about. My NS3C has a very mild buzz as well, but I believe it's just the power supply (capacitor buzz). I think it adds character! ;)

Sounds similar to this thread :oops:


I’ve read that post. That other post seem similar, but there were no solutions or explanations given. It definitely seems to be coming directly from the led displays. I contacted Clavia to see if it is something normal, or a bigger issue.

Update: Pablo recently told me that it's likely the transformer from the internal power supply.

perfectly normal. everything's fine. even my Nord Grand does it. so no worries at all.
Life is worth living. Do not fear death, accept it and adapt accordingly. Don't worry, All will be fine.

Hi Romanwave,
Thanks for uploading this video and welcome to the forum.
I expected (from datasheets) that these OLED produced kHz frequency buzzing.
I recorded the audio from your upload to Audacity and ran the spectrum and spectrogram. These show peaks at 3.7kHz, 6.9kHz and 13.7kHz.
Your video allowed me to confirm how this buzzing differs from the power supply hum.
