Reviews coming soon
Designed for churches, classrooms, studios, cafés, gyms, events, and advanced home setups that need to share the same audio across multiple speakers without running cables.
Powered by Auracast broadcast audio, Harmony A3 sends one audio source to 3 receivers out of the box and can be expanded to unlimited receivers for scalable multi-speaker systems.
Unlike traditional Bluetooth, receivers join the broadcast automatically with no manual pairing or repeated reconnecting, making setup, replacement, and expansion simple and reliable.
The transmitter supports Optical, 3.5 mm AUX, and classic Bluetooth audio input, while each receiver outputs audio via 3.5 mm AUX or RCA to powered (active) speakers. Passive speakers or speakers without built-in amplification are not supported.
Auracast audio may experience a slight delay of approximately 50–70 ms. In open spaces, wireless range can extend up to 100 m; however, walls and physical obstacles may affect signal strength and range.
