Setup
Follow these steps to connect your LITTOAK BS01 Powered Subwoofer to your audio system:
- Placement: Position the subwoofer in your desired location. Consider placing it near your main speakers or in a corner for enhanced bass response.
- Power Connection: Connect the supplied power cable to the subwoofer's power input and then to a wall outlet.
- Audio Connection (Line In): If your audio source (e.g., soundbar, receiver, TV) has an AUX OUT port, use the supplied 3.5mm-RCA audio cable. Connect the 3.5mm end to your device's AUX OUT and the RCA ends (red/white) to the LINE IN ports on the subwoofer.
- Audio Connection (LFE In): If your audio source has a dedicated SUB OUT or LFE OUT port, use a subwoofer cable (not supplied). Connect one end to your device's SUB OUT/LFE OUT and the other end to the LFE IN port on the subwoofer.
- Power On: Flip the power switch on the back of the subwoofer to the 'ON' position.

Operating Instructions
Once connected, you can adjust the subwoofer's settings for optimal audio performance:
- Volume Control: Use the 'VOLUME' dial on the back panel to adjust the overall bass level. Start with a low setting and gradually increase it to your preference.
- Low Pass Dial: The 'LOW PASS' dial (40Hz-250Hz) allows you to set the upper frequency limit for the subwoofer. Adjust this to blend the subwoofer's output seamlessly with your main speakers. A common starting point is around 80-100Hz.
- Phase Switch: The 'PHASE' switch (0°/180°) helps ensure that the subwoofer's sound waves are in sync with your main speakers. Experiment with both settings to find the one that produces the most impactful and coherent bass.
- Automatic Standby: The subwoofer features an auto on/off function. It will automatically enter standby mode after 15 minutes of inactivity and wake up instantly when an audio signal is detected. This feature helps save energy.
- 3D Tunnel Light & LED Effects: The subwoofer includes a 3D Tunnel Light with 6 LED effects (Red, Blue, Purple, Green, Yellow, Breathing). These visual effects enhance the ambiance of your listening environment. Refer to the quick start guide for specific controls to cycle through or disable these effects.
