Line-Out Audio

The line-out audio interface supports headphones and high­impedance audio systems. It is a 3.5 mm female jack with stereo
audio support. When connected to an active audio system input,
the output should be coupled capacitively into the audio system.
Most aftermarket built-in audio systems already include
capacitive coupling.
