- Use the app to select individual speakers or group multiple speakers to play the same music in perfect sync, or different tracks in different rooms.
- Adjust volume and EQ settings (left/right channels) through the app.
Bluetooth Pairing
For direct connection to a single device, use Bluetooth pairing.
- Ensure the speaker is powered on.
- Activate Bluetooth on your source device (smartphone, tablet, laptop).
- On the E-350 speaker, press and hold the Bluetooth pairing button (refer to speaker's physical controls for exact button, usually indicated by a Bluetooth icon) until the indicator light flashes, signifying pairing mode.
- On your source device, search for "QFX E-350" in the list of available Bluetooth devices and select it to pair.
