Hello, I am the proud owner of a kemper profiler rack unpowered. I ran it through a line 6 90 wireless set. Since my last few gigs sometimes the sound fully stops. I see a signal coming in the wireless but no sound. Also clicking pedals, switching rigs or turning the main knob from performance to tuning etc doesn't help. Only switching off and on helps. I thought it was the volume pedal but after not connecting it still gives this error 1 to 2 times during a gig.
Is there anybody who can help?
