06 · Common questions

Common questions

Does Harmony A0 require Wi-Fi or an app?

No. Connect the audio source to the transmitter, power on the included speakers and start listening. The included speakers connect automatically without a Wi-Fi network or app.

Can I add more speakers later?

Yes. You can add compatible Harmony speakers or additional transmitters as your space grows. Actual range and system layout depend on walls, floors and wireless interference.

What wireless range should I expect?

The system supports up to 328 ft line-of-sight. Walls, floors and wireless interference may reduce the practical range.

Can room speakers and personal hearing devices listen together?

Compatible speakers, headphones, earbuds, receivers and hearing devices can receive the same Auracast broadcast, allowing people to listen through room speakers or a preferred personal device.

Do I need to restart the speakers when the audio source stops?

The speakers remain powered on when the audio source stops, so music can resume without restarting or reconnecting the system.
