Harmony / Harmony 2 – How to Add More Speakers

Add another compatible Harmony speaker to your transmitter so all connected speakers can play the same audio at the same time.

Good to Know

Your existing speakers do not need to be paired again. Leave the speakers that are already working alone and pair only the new speaker.

Before You Start

Turn ON the Harmony transmitter.
Keep the new speaker close to the transmitter while pairing.
Add one new speaker at a time.
Make sure the new speaker is in Broadcasting mode.

⚠️ Important: Do not pair the new speaker to your phone by Bluetooth. The speaker needs to connect to the Harmony transmitter in Broadcasting mode.

Step 1 – Put the New Speaker in Broadcasting Mode

Turn ON the new Harmony speaker.

If needed, double-press the M button until you hear “Broadcasting mode.”

Flashing WHITE = Broadcasting mode

⚠️ Important: If the speaker is in Bluetooth mode, it will not connect to the Harmony transmitter.

Step 2 – Put the Transmitter Into Pairing Mode

On the Harmony transmitter, press and hold the ADD DEVICES button ADD DEVICES button for about 2 seconds.

Step 3 – Wait for Them to Connect

Keep the new speaker close to the transmitter and wait a few seconds.
