Harmony 2 - How to Add More Speakers

You can pair up to 100 receivers—including Harmony extra speakers, Quartet extra headphones, or Duet extra headphones—with the Avantree Flex Base transmitter. Once your transmitter is set up, you can easily add more receivers and adjust their volumes independently.

Here's how:

1. Put the Transmitter into Pairing Mode:
Turn on the transmitter, then press and hold the button until the “Add Devices” LED begins flashing.

2. Put the New Speakers into Pairing Mode:
Turn on the Harmony 2 speaker and make sure it’s in Broadcasting mode. Then, press and hold the M button until the “Status” LED flashes red and blue.

3. Wait for Connection:
Within 3–5 seconds, the LEDs will turn solid, indicating a successful connection.

💡 Tips:
1. Minimize Interference: Wi-Fi routers, access points, and microwaves operate on the 2.4GHz frequency and can interfere with the signal. Keep these devices at least 2 meters away from your speakers and transmitter for best performance.

2. Double-click the M button to switch between Broadcasting and Bluetooth mode. (For units before Batch T24L1, use a single click.)
