4. Setup Guide
4.1 Unpacking and Placement
Carefully remove the subwoofer from its packaging. Place the subwoofer on a stable, level surface. The front-firing design allows for flexibility in placement, but generally, placing it in a corner or along a wall can enhance bass output. Experiment with different positions to find the best sound for your room.

4.2 Connections
Ensure your audio system (AV receiver, amplifier) is turned off before making any connections.
- Power Connection: Connect the provided power cable to the AC inlet on the rear of the subwoofer and then to a suitable wall outlet.
- Audio Input: The Aurora Subwoofer 30A supports RCA or 3.5mm jack connectivity.
- RCA Input (Recommended for AV Receivers): Connect an RCA cable from the "SUBWOOFER OUT" or "LFE OUT" port on your AV receiver to the "L" (Left) RCA input on the subwoofer. If your receiver has a stereo subwoofer output, connect both "R" and "L" inputs.
- 3.5mm Jack Input (for other devices): If connecting to a device with a 3.5mm audio output, use an appropriate adapter cable to connect to the RCA inputs.

5. Operating Instructions
5.1 Powering On/Off
- Main Power Switch: Locate the main power switch on the rear panel. Flip it to the "ON" position to power on the subwoofer.
- Auto On/Off: The subwoofer features an "AUTO" mode. When set to "AUTO", the subwoofer will automatically turn on when it detects an audio signal and enter standby mode after a period of inactivity. For continuous operation, set the switch to "ON".
5.2 Adjusting Controls
The rear panel features several controls to fine-tune the subwoofer's performance to your listening environment and preferences:
- Volume: Adjusts the overall output level of the subwoofer. Start with a low setting and gradually increase until the bass blends seamlessly with your main speakers.
- Frequency (Crossover): This knob sets the upper frequency limit for the subwoofer. It typically ranges from 50 Hz to 150 Hz. Adjust this to match the low-frequency capabilities of your main speakers. If your main speakers have good bass extension, set it lower (e.g., 80 Hz). If they are smaller, set it higher.
- Phase (0°/180°): This switch adjusts the phase of the subwoofer's output relative to your main speakers. Experiment with both settings (0° and 180°) to find the one that produces the most impactful and coherent bass at your listening position. The correct setting will result in stronger, more defined bass.
For optimal integration, it is recommended to use your AV receiver's automatic room correction system (if available) after initial manual adjustments.
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the cabinet. Avoid abrasive cleaners, solvents, or chemical sprays, as these can damage the finish.
- Dust: Regularly dust the subwoofer, especially the woofer cone and rear panel, to prevent dust buildup.
- Placement: Ensure the subwoofer is placed in a well-ventilated area, away from direct sunlight, heat sources, and excessive moisture.
- Grille: The magnetic grille can be removed for cleaning or if you prefer the aesthetic of the exposed woofer. Handle with care.
