WIRING THE AUDIO OUTPUT
On the 3.5mm Plug, (not provided) the Tip is the first
Audio Output, the Ring is the second Audio Output,
and the Barrel is the Shield or Ground. There is no
need to designate Left or Right as both Audio Out-
puts provide the same signal.
OPTIONAL 3.5MM STEREO AUDIO PLUG AND CABLE
To EDS
Audio Jack
To Aircraft
TYPICAL COMMUNICATIONS WIRING
The standard wiring option has one Audio Out-
put wired to the Left Input and the other Audio
Output wired to the Right Input.

TWO O2D2-2G UNITS DRIVING ONE INPUT
The outputs from one O2D2-2G
May NOT
be tied to the outputs
from another O2D2-2G. In the case
of installing two O2D2-2G units in
an aircraft, each should be given its
own input to the communications
system. If this is not an option,
then wire the Audio Output of one
O2D2-2G to the Left Input and the Audio
Output of the other O2D2-2G to the Right
Input.

DRIVING A LOW IMPEDANCE INPUT
The Audio Outputs of an O2D2-2G are designed to
drive standard stereo inputs with impedance from
1000
Ω
to 10,0000
Ω
. To accommodate a lower
impedance input, parallel both Audio Outputs
