The audio input supports Line Level (external) audio/microphone input @ 600-ohm differential 1Vp-p maximum signal level, which means that the audio must be pre-amplified to the desired volume before reaching the Positioning System.

The audio input connector that comes with the camera is an open-wire insert type with positive and negative leads…

(connect the microphone onto this before mounting the Positioning System)

…which plugs into the base of the Positioning System here…

Some good pre-amplification kits (amplifier + microphone) are offered by Louroe, here…
