AuraPlex M3 – How to Use FreeMic Duo as the Audio Source

Follow these 8 simple steps to connect your FreeMic Duo microphones to the AuraPlex system and listen through wired earbuds.

How it works: FreeMic Duo sends microphone audio wirelessly to its receiver. The receiver connects to the Oasis Aura transmitter through AUX. The transmitter broadcasts the audio to the AuraPlex receiver, where you can listen using wired earbuds.

Before starting: Prepare the FreeMic Duo microphones and receiver, 3.5mm adapter, 3.5mm audio cable, AuraPlex transmitter, AuraPlex receiver, and wired earbuds.
