Note: The sensitivity range of 1 mV to 20 mV was qualified under
environmental conditions.
Two dynamic microphones in parallel may be connected (identical
technical characteristics of the microphones are preferable).
It is highly recommended to install the microphone jacks isolated from
aircraft ground in order to avoid ground loops.
Speaker Connection
Pin No.
Direction Function
P1-1 SPK_HI OUT Speaker output (HI)
P1-14 SPK_LO - Speaker LO (ground/return)
The speaker output provides nominal 4 Watts into 4 Ohm.
CAUTION: The magnetic field of a speaker may influence the magnetic
compass.
When choosing the installation place, a distance where the
magnetic compass is not affected must be determined. After
the speaker is installed accuracy of the compass operation
must be verified.
Headphone Connection
Pin No.
AR6201 Pin Name Direction Function
P1-2 HDPH_A OUT Balanced Output for headphone(s)
P1-3 HDPH_B OUT Balanced Output for headphone(s)
The headphone output is a balanced and transformer coupled output
providing nominal 300 mW into 150 Ohm.
Up to two headphones with an impedance of 300 Ohm (or higher) may be
connected in parallel.
Because the headphone output is balanced and in most installation the
use of a single shielded wire for headphone is very popular, P1-3 can be
grounded (connection to pin P1-13/P1-25). In that case, the balanced
output becomes unbalanced.
It is highly recommended to install the headphone jacks isolated from
aircraft ground in order to avoid ground loops.
