Audio Source Mode Switching
The amplifier box defaults to Bluetooth audio input and can be switched to optical/coaxial/other audio inputs via the MODE button. When switched to optical or
coaxial input, the corresponding indicator light below will remain on.
When switched to other modes, the audio source priority is AUX IN > Bluetooth. That is, when AUX IN is connected, the system will prioritize playing audio from
AUX IN. Bluetooth audio will only be available after the AUX IN cable is unplugged.
Note:
◼ When switched to optical/coaxial mode or when the AUX IN cable is plugged in, Bluetooth will not be discoverable. Bluetooth is also unavailable when a USB
flash drive is inserted.
◼ When wirelessly connected to certain TV models or using specific apps, audio and video may not be perfectly synchronized. Actual performance depends on
the TV or phone.
◼ Optical/coaxial inputs may encounter compatibility issues with certain TV or media player models. Please refer to the TV’s specifications.
◼ AUX IN and AUX OUT cables must use a 3-segment (TRS) AUX connector.
