3. Speaker-level connection: Connect speaker wires from amplifier to speaker-level inputs if needed.
4. Plug into AC power outlet.
5. Turn on power switch on rear panel.

WARNING! Subwoofer is heavy; lift with proper technique. Ensure adequate ventilation around unit.

First-Time Setup

Power on subwoofer; adjust controls for optimal performance.

1. Set volume level: Start at 50% and adjust while playing content with bass.
2. Adjust crossover: Set between 80Hz-120Hz initially, fine-tune to match main speakers.
3. Set phase: Start at 0°, adjust while playing bass-heavy content for smoothest integration.
4. Auto power: Enable auto on/off feature for energy efficiency.
5. Test with various content: Music, movies, and games to verify performance.

CAUTION! Avoid placing near heat sources or in direct sunlight.
