SQ5 whit AR2412 stage box

Hi Yesterday evening I was working with my SQ5 and the AR24 stage box (20 channels packed and external wifi router) When I switched on the first 8 channels were ok From channel 9 onwards on all channels, pink noise was present. In the setup pink noise was disabled, unassigned and with zero level. I brought all the channels from 9 onwards to the local bench to be able to work. Today in the studio, the mixer with the stage box does not show any anomalies. Problems with the power supply of the location?

Grazie

Problems with the power supply of the location?

No. Must be something else. Mostly it’s error code 1.

Did you try rebooting everything at the time?
