6. Setup

6.1 Placement

Position the subwoofer on a stable, flat surface. For optimal bass response, consider placing it in a corner or near a wall. The SWA18 includes a pole mount insert on top, allowing you to mount a satellite speaker directly above it using a standard speaker pole (sold separately).

6.2 Connections

Ensure the subwoofer is powered off before making any connections.

• Connecting to a Mixer/Audio Interface (XLR): Connect an XLR cable from the main output of your mixer or audio interface to the XLR Input on the SWA18.
• Daisy-Chaining (XLR Through): To connect additional active speakers or subwoofers, use an XLR cable from the XLR Through output of the SWA18 to the input of the next device.
• Connecting Consumer Devices (RCA): For devices with RCA outputs (e.g., some media players, game consoles), connect RCA cables to the RCA Input.
• Power Connection: Connect the supplied power cable to the Power Inlet on the rear panel, then plug the other end into a suitable AC power outlet.

7. Operating the Subwoofer

1. Power On: After all connections are made, switch the Power Switch to the ON position.
2. Set Input Level: Start with the Input Level knob at its minimum position. Play audio through your system and slowly increase the Input Level until the desired bass volume is achieved. Avoid setting it too high to prevent distortion.
3. Adjust Frequency (Low-Pass Filter): Use the Frequency knob to set the crossover point. A lower frequency (e.g., 80Hz) is typically used when pairing with full-range speakers, allowing the subwoofer to handle only the deepest bass. A higher frequency might be used with smaller satellite speakers. Adjust this to blend smoothly with your main speakers.
4. Set Phase: Experiment with the Phase switch (0° or 180°). Listen for the strongest and clearest bass response. The correct phase setting ensures the subwoofer's sound waves align with those of your main speakers, preventing cancellation and enhancing overall bass impact.
5. Power Off: When finished, switch the Power Switch to the OFF position.

8. Maintenance

8.1 Cleaning

Regularly clean the exterior of the subwoofer with a soft, dry cloth. Do not use liquid cleaners, solvents, or abrasive materials, as these can damage the finish. Ensure the unit is unplugged before cleaning.

8.2 Storage

If storing the subwoofer for an extended period, ensure it is kept in a dry, dust-free environment. It is recommended to use the original packaging for protection.
