Wiring (Circuit diagram)
The following figures show the wiring of the signals A, B, N and MF. The blue colored
switches show settings which apply across all channels, the yellow colored switches ap-
ply to a single signal A, B, N or MF. That means that parameters of the blue switches
apply to the A/B/N signals and to the MF signal.
