Fractal FM3 into "FX send" unit works fine! Regular amp into "Amp In" = no attenuation, no loop

It’s critical you have an extremely basic setup for the following:

  1. Ensure you amp works properly by itself, without connecting it to the Power Station. What is the amp make and model?
  2. No FX
  3. Verify that all your instrument, speaker and jumper cables all work reliably.

Please go through the checklist steps Power Station: Troubleshooting Guide

I’d like you to do the following checks:

  1. No sound
  2. Won’t switch to operate
  3. Effects not operating

Sorry if this sounds a little repetitive. It’s really important we understand your setup and eliminate mundane issues before considering a repair.
