Q & A

Q1. What is Harmony A1 and who is it for?
A: Harmony A1 is a wireless Multiroom Speaker System designed for indoor shared audio. It works best for homes, cafés, restaurants, meeting rooms, classrooms, retail spaces, and small indoor gatherings. For large outdoor events or high-volume party use, a higher-power speaker system may be a better fit.

Q2. How many Harmony A1 speakers can I connect?
A: With Auracast, Harmony A1 can connect to unlimited compatible speakers or headphones from one transmitter. You can start with a small setup and add more speakers anytime as your multiroom audio needs grow.

Q3. Does Harmony A1 require Wi-Fi or an app?
A: No. Harmony A1 works without Wi-Fi or an app. Connect your phone, computer, or other audio source to the transmitter, power on the speakers, and start listening.

Q4. Can I use Harmony A1 with TVs?
A: Yes, but Harmony A1 is designed for shared room audio, not TV lip-sync listening. Since wireless transmission adds some delay, we do not recommend using it together with your TV’s built-in speakers.

Q5. What devices can Harmony A1 work with?
A: Harmony A1 supports audio input through Bluetooth, Optical, and AUX (depending on transmitter model). It works with phones, laptops, tablets, media players, and other audio sources.
