Setup

1. Placement

Optimal subwoofer placement is crucial for sound quality. Consider the following:

• Corner Placement: Placing the subwoofer in a corner of the room can enhance bass output, making it sound louder.
• Near Main Speakers: Positioning the subwoofer close to your front main speakers can improve the blend between the subwoofer and the main speakers, creating a more cohesive soundstage.
• Experimentation: Room acoustics vary. Experiment with different locations to find the best balance of bass impact and clarity for your listening environment.

2. Connections

The SW-8MK2 offers flexible connection options:

• Line Level Input (RCA): For receivers or pre-amplifiers with a dedicated subwoofer output (LFE or Sub Out). Connect a single RCA cable from your receiver's subwoofer output to the LFE input on the subwoofer. If your receiver has separate Left/Right RCA outputs for the subwoofer, connect both.
• Speaker Level Input: For receivers or amplifiers without a dedicated subwoofer output. Connect speaker wires from your receiver's main speaker outputs to the HI LEVEL IN terminals on the subwoofer. Then, connect your main speakers to the HI LEVEL OUT terminals on the subwoofer. Ensure correct polarity (+ to + and - to -).

3. Power Connection

Once connected to your audio system, plug the supplied power cord into the AC INLET on the subwoofer's rear panel and then into a standard 120V/60Hz AC wall outlet.

Operating the Subwoofer

The rear panel of the SW-8MK2 features several controls for fine-tuning its performance:

• VOLUME Knob: 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.
• FREQ (Crossover) Knob: Sets the upper frequency limit for the subwoofer. Frequencies above this setting will be sent to your main speakers. Adjust this to match the low-frequency capabilities of your main speakers. A common starting point is 80 Hz.
• PHASE Switch (0°/180°): Adjusts the phase of the subwoofer's output relative to your main speakers. Experiment with both settings to find the one that provides the most impactful and cohesive bass.
• POWER Switch (ON/AUTO/STANDBY):
  • ON: The subwoofer remains continuously on.
  • AUTO: The subwoofer automatically turns on when an audio signal is detected and enters standby mode after a period of inactivity.
  • STANDBY: The subwoofer remains in a low-power standby state, waiting for a signal to turn on.

Placement Recommendations

While corner placement often boosts bass, consider these points for optimal sound:

• Avoid Enclosures: Do not place the subwoofer in an enclosed cabinet, as this can lead to boomy and indistinct bass.
• Wall Proximity: Placing the subwoofer closer to a wall (but not directly against it) can reinforce bass frequencies.
• Listening Position: The bass response can vary significantly depending on your listening position. Test different subwoofer placements from your primary listening spot.

Maintenance

To ensure the longevity and optimal performance of your subwoofer, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the cabinet. Avoid abrasive cleaners, solvents, or strong detergents.
• Dusting: Regularly dust the woofer cone and grille to prevent buildup that could affect sound quality.
• Ventilation: Ensure adequate airflow around the subwoofer to prevent overheating. Do not block the rear panel or any vents.
• Avoid Moisture: Keep the subwoofer away from water and excessive humidity.

Troubleshooting

If you encounter issues with your subwoofer, refer to the following common problems and solutions:

• No Sound:
  • Check if the power cord is securely plugged into both the subwoofer and the wall outlet.
  • Ensure the POWER switch is set to ON or AUTO.
  • Verify that the audio input cables are correctly connected to both the subwoofer and your receiver/amplifier.
  • Increase the VOLUME knob on the subwoofer and the subwoofer level on your receiver.
• Distorted or Boomy Sound:
  • Reduce the VOLUME knob on the subwoofer.
  • Adjust the FREQ (Crossover) knob to a lower setting.
  • Try changing the PHASE switch setting (0° or 180°).
  • Experiment with different subwoofer placements in the room.
• Insufficient Bass:
  • Increase the VOLUME knob on the subwoofer and the subwoofer level on your receiver.
  • Adjust the FREQ (Crossover) knob to a higher setting.
  • Try changing the PHASE switch setting (0° or 180°).
  • Consider repositioning the subwoofer, possibly closer to a corner or wall.
