Figure 5: system overview controlling via digital inputs (mode 3)
In mode 3 the power supply of the AMP 4/8 and the ARE i2 are seperatly. The switching of the channels
is done binary via the digital inputs. The inputs are low-activ, that means that you have to pull them to
ground to get a logical ‘1’ (see figure 6).
