4.3 Front Panel Audio Cable
4.3.1 Introduction
This section details the design of an audio cable to be used in conjunction with the front panel I/O
board.
The shielding in this cable is important to reduce cross talk, signal degradation, and coupling of
electromagnetic interference. The shielding is particularly important for the microphone circuit
since it is a low-level signal and is very sensitive to noise.
The suggested maximum length for this cable is 18 inches as shown in Figure 11. Figure 12 and
Figure 13 show the cable shielding details. Table 13 and Table 14 list the pin assignments and
materials list. Table 15 provides additional information for the audio cable.
