Hi Dieter,

I am using 4 x A-156 together. The input threshold tracking is usable but a bit tricky with one of the modules being slightly different. I have read the A-156 adjustment guide and have the correct tools to hand. I understand how P1, P2 and P3 adjust the input scale but would like to understand if recalibrating them might help with a little input offset. Any thoughts appreciated.

Many thanks for your time and attention.

Kind Regards,

John Hollis
