But still cant find the issue why the relay is rattling when connected to DC plug....

Any ideas out there?

[Numark PT01 motor noise issue]

I need some help on this.

 

I have a PT01 which makes this noise in play. This is not related to the volume knob. It comes out from the internal speaker and from the headphone out / RCA if connected:

 

(in the video the noise is low so you have to turn the volume up)

 

I tried to see if it has to do with the battery mod, but connecting it with the AC it gives me another issue:

 

 

I really don't know what this issue is and it never bothered me since I wanted to install the ultrapitch mod, which made this noise 10 times louder.

 

Someone can help?
