Here’s a guide for correcting the “no noise visible” issue for future readers.
- Unmount your module so you can access the rear PCB, but leave it connected to EuroRack power supply. Monitor the “White noise” output jack.
- Wait for 5 minutes or so, so that it warms up to operating temperature. Grab a small philips screwdriver.
- While monitoring the output, adjust the trimmer highlighted in red in the below image. Turn it slowly until you see noise reappear on the output jack. Stop.
- Power off your system. Wait a bit. Turn it back on and verify that the noise output still looks good. It should, as long as you didn’t over-adjust the trimmer. If not, make another tweak and try again.
- Should be all good now!
