Analog Inputs
Two analog inputs are present on the CMK. The user must ensure that there is one connection to Ground on pin ‘3’,
one connection to an appropriate positive voltage (usually +5V) on pin ‘1’, and one connection to an analog input pin.
Analog inputs are used for crescendo and volume/expression adjustment as shown in Figure 13.
Figure 13: Wiring Schematic for Analog input
The CMK has provision for up to four extra input functions on the circuit board. These inputs are reserved for future
use.
