Retrofitting an AR4201 with the AR62X1 in a typical glider installation with a dynamic microphone:

• Connect the cable shield to P1-6, which is the low side input for dynamic microphone.
o Because in AR62X1 this input is balanced, the cable shield is no longer connected to
ground (unlike it was with the AR4201). In most cases, it is not a problem.
• If interference with the microphone signal does occur, it is recommended to connect P1-6
with Pin P1-8 (the cable shield is grounded).
