Can I play music from my connected source using Bluetooth and AUX at the same time?

You cannot connect the same source to HYPERBOOM using both Bluetooth AND Aux In. In this case, your music using Bluetooth will not stream since Aux In is also plugged into the same source. Either unplug the Aux In to stream Bluetooth, or disconnect from the Bluetooth channel from the source to play via Aux on the music source device.
