Q: Will this work across my whole home or party space?
A: Yes. Harmony A1 supports wireless audio up to 100 meters (328 ft), making it ideal for large homes, garages, and party areas—far beyond standard Bluetooth range.
Q: What can Auracast actually do for me?
A: Auracast™ lets one audio source broadcast to many listeners at once, including compatible earbuds and hearing aids, making shared listening more flexible and inclusive.
Q: Can I add more speakers or create different groups?
A: Yes. You can add more Harmony speakers and create separate groups by setting different passwords, allowing multiple zones or group playback in the same space.
Q: What's the difference between Harmony A1 and Harmony 2?
A: Harmony 2 focuses on ultra-low 30ms latency using 2.4G wireless. Harmony A1 uses Auracast™, reaches up to 100m, works with hearing aids, and offers future-ready audio features.
Q: Can each speaker be used on its own?
A: Yes. Each speaker can be used independently via classic Bluetooth, or combined into a synchronized group when used with the Harmony system.
