  • Auracast™ Broadcast – Works with any Auracast broadcast source (e.g. Avantree Harmony A2 and all Avantree Auracast transmitters)

Notes

  • Latency & Codec – Lowest A/V delay is achieved when both sides support aptX Adaptive. Otherwise, the speakers fall back to SBC with standard latency. With Auracast, latency depends on the LE Audio source.
  • No Bluetooth? Use a Transmitter – For older TVs or to guarantee the lowest latency, use a compatible Bluetooth transmitter (sold separately) that supports aptX Adaptive.

Perfect for TV, music, or group listening indoors/outdoors.

Q & A

Q1: Can I connect the speaker to any open Auracast transmitter?
A1: Yes. The Harmony A2 Solo works with any open Auracast transmitter. If multiple sources are nearby, it will automatically connect to the strongest signal.

Q2: What is Auracast and how do I use it?
A2: Auracast lets multiple speakers play the same sound at once. The Harmony A2 Solo works with the Harmony A2 or any open Auracast transmitter for group listening.

Q3: Does the Harmony A2 Solo speaker have audio delay for TV?
A3: If you connect directly to a TV’s Bluetooth, noticeable delay may occur. For low latency, use a transmitter (sold separately) that supports aptX Adaptive or Auracast LE Audio.

Q4: How long does the battery last?
A4: Up to 8 hours on a single charge. Charging takes about 4 hours via USB-C, and you can also use the speaker while charging.
