[MULTI-SPEAKER SYSTEM] Connect the Harmony 2 transmitter to an audio source such as your phone, laptop, or TV via Bluetooth, optical, or AUX, and output audio through all three speakers simultaneously. The range between the speakers and the transmitter is 65 ft (20 m), and the range between the transmitter and the Bluetooth audio source is 15 ft (5 m).
[ALWAYS IN SYNC] With a latency of less than 30ms, the speakers work perfectly in sync with each other with no audio delays, echoes, or stutters.
[SCALABLE TO 100] Connect up to 100 Harmony 2 add-on speakers to the transmitter while maintaining low latency. Please note that ONLY Harmony 2 add-on speakers are compatible due to private protocol connections.
[EFFORTLESS SETUP] Turn the transmitter and speakers on and they’ll automatically connect – no app or pairing required.
[INDEPENDENT USE] Each speaker can also connect independently to your phone, tablet, laptop, or any other Bluetooth enabled device.
