Setup and Installation

Placement:

Due to the human ear's difficulty in localizing low-frequency sound waves below 80 Hz, the subwoofer offers flexible placement options within your living space. For optimal sound, consider the following:

• Central Installation: Ideally, place the subwoofer between your two front speakers.
• Distance from Walls/Corners: Avoid placing the subwoofer directly against a wall or in a corner, as this can lead to boomy and imprecise bass reproduction. Maintain an optimal distance of 30 to 50 cm (approximately 12 to 20 inches) from walls. Free-standing placement in the room is also acceptable.

Connections:

Connect the subwoofer to your audio system using appropriate RCA or speaker wire connections. Ensure all connections are secure before powering on the device.

• Power Connection: Plug the power cable into the subwoofer's power input and then into a suitable wall outlet.
• Audio Input: Connect the audio output from your amplifier or AV receiver to the subwoofer's input. The subwoofer supports RCA and speaker wire protocols.

Operation

Initial Power-On:

After connecting all cables, switch on your audio system and then the subwoofer. The subwoofer typically has an auto-on/off feature that activates it when an audio signal is detected.

Adjustments:

The Canton AS 85.2 SC offers several adjustments to integrate it seamlessly into your audio environment:

• Crossover Frequency: Adjust the crossover frequency between 55 and 200 Hz to blend the subwoofer's output with your main speakers. Start with a setting slightly above your main speakers' lowest frequency response.
• Phase Adjustment: Use the phase control to ensure the subwoofer's output is in phase with your main speakers, preventing cancellation or reinforcement issues. Experiment with 0° and 180° settings to find the most coherent bass.
• Bass Level: Adjust the bass level to achieve the desired impact without overpowering the rest of your audio system.

Break-in Period:

To achieve optimal sound performance, the manufacturer recommends a break-in period of 15 to 20 hours of operation at normal volume. During this period, avoid extremely high-level peaks and use various music materials to allow the driver components to settle.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the subwoofer's cabinet. Do not use liquid cleaners or abrasive materials.
• Ventilation: Ensure that the ventilation openings are clear of dust and debris to prevent overheating.
• Storage: If storing the subwoofer for an extended period, disconnect it from power and store it in a cool, dry place.

Troubleshooting

If you experience issues with your Canton AS 85.2 SC subwoofer, refer to the following common troubleshooting steps:

• No Power:
  • Check if the power cable is securely connected to both the subwoofer and the wall outlet.
  • Verify that the wall outlet is functional by plugging in another device.
  • Ensure the subwoofer's power switch is in the "ON" position.
• No Sound:
  • Check all audio connections between the subwoofer and your amplifier/receiver.
  • Ensure the subwoofer's volume/level control is not set to minimum.
  • Verify that your amplifier/receiver is sending a signal to the subwoofer output.
  • Adjust the crossover frequency; if set too low, the subwoofer may not produce audible sound with certain content.
• Distorted or Boomy Bass:
  • Adjust the bass level control on the subwoofer or your receiver.
  • Experiment with the phase control (0° or 180°).
  • Relocate the subwoofer, ensuring it is not too close to walls or corners (refer to Placement section).
  • Check for any loose objects near the subwoofer that might be rattling.

If the problem persists after trying these steps, contact Canton customer support or a qualified service technician.
