Inputs / Outputs Detailed Description

Microphone Connection – Carbon Microphone Standard
Pin No. AR6201 Pin Name
P1-8 MIKE_STD_LO
P1-18 MIKE_STD_HI
For interfacing
unbalanced input with an input impedance of 110 Ohm and a nominal
sensitivity of 110 mV. This sensitivity level can be adjusted in the
Installation Setup from 9 mV to 1500 mV. The power supply delivered from
pin 18 for supply of the connected microphone(s) is > 8 V DC (8.3 V
nominal) open circuit.
Note: Sensitivity
environmental conditions
For all popular aviation microphones the power supply is capable to
supply two microphones in parallel.
Care should be taken to combine only microphones of the same type /
impedance.
It is highly recommended to mount the jacks isolated from aircraft frame
in order to avoid ground loops.

Microphone Connection - Dynamic Microphone

Pin No. AR6201 Pin Name
P1-5 MIKE_DYN_HI
P1-6 MIKE_DYN_LO
For interfacing with dynamic microphone the transceiver has a balanced
input with an impedance of 140 Ohm and a nominal sensitivity of 3.5 mV.
This sensitivity level is adjustable in the Installation Setup from 0.5
mV to 25 mV.
