Subwoofer Rear Panel Controls:
- MAIN Level: Adjusts the overall output volume of the system.
- SUB Level: Adjusts the volume of the subwoofer independently.
- Cardioid ON/OFF: Activates or deactivates the cardioid dispersion mode for the subwoofer, reducing rearward sound radiation.
- Input L/R: XLR/TS combo jacks for connecting audio sources (e.g., mixer, instrument).
- THRU L/R: XLR outputs for linking to additional PA systems or monitors.
- SUB OUT: XLR output for connecting an external subwoofer.

- Unpack Components: Carefully remove all components from their packaging.
- Position Subwoofer: Place the subwoofer on a stable, level surface in your desired location.
- Assemble Column Elements:
- Take the first column element and align its base connector with the top connector of the subwoofer. Gently push down until it clicks into place.
- Take the second column element and align its base connector with the top connector of the first column element. Gently push down until it clicks into place.
- Connect Audio Source: Connect your mixer, instrument, or other audio source to the Input L/R XLR/TS combo jacks on the subwoofer's rear panel.

6. Operation
- Power On: Ensure all connections are secure, then switch the power button on the subwoofer to the 'ON' position.
- Adjust Levels: Start with the MAIN Level and SUB Level knobs set to their minimum positions. Gradually increase the MAIN Level to your desired overall volume. Adjust the SUB Level to balance the bass frequencies with the rest of the sound.
- Cardioid Mode: If you wish to reduce sound radiation behind the subwoofer, activate the Cardioid ON switch. This can help minimize stage rumble and improve sound clarity in certain environments.
- Monitoring/Linking: Use the THRU L/R outputs to send the audio signal to additional PA systems or stage monitors if required. The SUB OUT can be used to connect an external subwoofer for enhanced bass.
- Power Off: Before disconnecting power, turn down all level controls to minimum, then switch the power button to 'OFF'.
7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior surfaces of the system. Do not use abrasive cleaners or solvents.
- Storage: When not in use, store the system in a dry, dust-free environment. If transporting, use appropriate protective covers or cases.
- Inspection: Periodically check all cables and connectors for signs of wear or damage.
