Harmony 2 - How to Avoid Sound Cutting Out, Adjust Sound Modes, and Use While Plugged In? – Avantree Support

1. To avoid sound cutting out:

🚫 Stay Within Range: Keep your Bluetooth device within 4.5m (15 ft) of the transmitter.
💡 Minimize Interference: Wi-Fi routers, access points, and microwaves use the 2.4GHz frequency and may disrupt the signal. Keep them as far away as possible from your speakers and transmitter.

2. Not satisfied with the sound?

🎛️ Press "+" and "-" buttons on the transmitter simultaneously to switch between Normal, Voice Clear, and Bass EQ modes.

🔊 Not loud enough? Press "+" or "-" to adjust the volume within the selected mode.

3. Can I use the Harmony 2 speakers while charging?
Yes, you can definitely use the Harmony 2 speakers while they are plugged in. However, please note that when switching from battery mode to plugged-in mode, the speakers may momentarily disconnect. If this happens, simply turn them on again. They will automatically reconnect and can then be used continuously while plugged into power. This setup is designed to be convenient for environments like workrooms where constant power is beneficial.

4. Can I pair a different Bluetooth speaker to the transmitter?
No, the Avantree Flex Base transmitter does not support pairing with Bluetooth speakers. While it offers three audio input modes (Phone, OPT, and AUX), in Phone mode, it is designed to connect with audio source devices (such as Bluetooth-enabled phones, tablets, computers, or TVs) rather than audio output devices like Bluetooth speakers, headphones, or soundbars.

💡Tip:

The 5049 series (Quartet, Quartet 2) and 5308 series (Harmony, Harmony 2) share the same 2.4GHz chipset. This means their transmitters and receivers are compatible! Just put both into pairing mode to connect them.
