How to Use a Wireless Microphone with Avantree Harmony 2

START HERE

Use this setup to play microphone audio through multiple Harmony 2 speakers.

Good to know: Harmony 2 is best for small-to-medium indoor spaces, group listening, and voice support. It is not a replacement for a professional PA system.

Not suitable for:

Large venues that need PA-level amplification
High-bass music playback
Stage performances or live events
Very loud speaker setups

What You Need

A wireless microphone set with a receiver that has LINE OUT or AUX OUT.
A 3.5 mm female-to-male AUX extension cable.
A TRS AUX cable.
A working Harmony 2 transmitter and connected speakers.

View 3.5 mm AUX Extension Cable

Use TRS only. Do not use a TRRS AUX cable. The transmitter requires a TRS cable for this connection.

Connect the Microphone

Make sure your Harmony 2 transmitter and speakers are already set up and working.
Connect the microphone receiver’s LINE OUT / AUX OUT to the Harmony 2 Flex Base’s AUX IN port.
Turn ON the microphone and receiver.
Start Group Listening pairing or broadcasting.

Your voice will play through all connected Harmony 2 speakers.

Wireless microphone connection to Harmony 2

Set the Volume

Set the microphone output to about 50–80%, then adjust the Harmony 2 speaker volume to a comfortable level. This helps prevent distortion.

Something Doesn’t Look Right?

Microphone Sound Is Too Quiet

Some wireless microphones have a weak mic-level output. If the volume is still too low, use a mic preamp or a PA speaker with a microphone input and gain control between the microphone receiver and Harmony 2 transmitter.

Microphone Receiver → Preamp → Group Listening Transmitter → Avantree Speakers

Sound Is Distorted

Lower the microphone receiver output, then adjust the speaker volume. Avoid setting the microphone output to maximum volume.

No Voice Through the Speakers

Make sure the microphone and receiver are ON.
Check the cable connection: receiver LINE OUT / AUX OUT to Flex Base AUX IN.
Confirm that you are using a TRS AUX cable.
Make sure the Harmony 2 speakers are connected to the Flex Base.
