2. Safety Instructions

4. Setup

4.1. Placement

The placement of your subwoofer significantly impacts its performance. Experiment with different locations to find the best sound for your room.

Corner Placement: Placing the subwoofer in a corner often provides the most bass output due to room acoustics.
Near Front Speakers: Placing the subwoofer near your main front speakers can help create a more seamless soundstage.
Avoid Obstructions: Ensure the front-firing woofer is not obstructed by furniture or other objects.

4.2. Connections

Before making any connections, ensure the subwoofer and your audio receiver/amplifier are turned off and unplugged from the power outlet.

LFE (Low-Frequency Effects) Connection: If your AV receiver has an LFE or Subwoofer Pre-Out jack, connect a single RCA cable from this output on your receiver to the LFE input on the Canton AS 105. This is the recommended connection for home theater systems.
Stereo RCA Connection: If your receiver does not have an LFE output, connect stereo RCA cables from your receiver's Pre-Out (or Front Left/Right Pre-Out) to the Left and Right Line-In inputs on the subwoofer.
Power Connection: Once audio connections are made, connect the supplied power cable to the subwoofer's power inlet and then to a suitable AC wall outlet.

5. Operation

5.1. Power On/Off

The Canton AS 105 features an auto-on/off function. When an audio signal is detected, the subwoofer will automatically power on. After a period of inactivity (no audio signal), it will enter standby mode.

Power Switch: A main power switch is located on the rear panel. Set it to the 'ON' position for normal operation.
Auto Standby: The subwoofer will automatically switch to standby mode when no audio signal is present for approximately 15-20 minutes. It will reactivate upon detection of an audio signal.

5.2. Controls

Adjust the following controls on the rear panel to integrate the subwoofer with your main speakers and room acoustics:

Volume/Gain: Adjusts the output level of the subwoofer. Start with a low setting and gradually increase until the bass blends seamlessly with your main speakers without overpowering them.
Crossover Frequency: This control determines the highest frequency the subwoofer will reproduce. Set it to match the low-frequency capabilities of your main speakers. A common starting point is 80 Hz, but refer to your main speaker specifications or experiment for optimal blending. If using an AV receiver with bass management, set the subwoofer's crossover to its maximum setting or bypass if available, and manage the crossover through the receiver.
Phase Switch (0°/180°): This switch helps to ensure the subwoofer's output is in phase with your main speakers. Listen to music with strong bass and toggle the switch between 0° and 180°. Choose the setting that provides the most impactful and coherent bass.

6. Maintenance

To ensure the longevity and optimal performance of your Canton AS 105 subwoofer, follow these maintenance guidelines:

Cleaning: Dust the cabinet regularly with a soft, dry, lint-free cloth. For stubborn marks, slightly dampen the cloth with water, then wipe dry immediately. Avoid abrasive cleaners, solvents, or polishes.
Ventilation: Periodically check that the ventilation openings are clear of dust and debris.
Cable Connections: Occasionally check all cable connections to ensure they are secure. Loose connections can lead to poor sound quality or intermittent operation.
Avoid Extreme Conditions: Do not expose the subwoofer to extreme temperatures, high humidity, or direct sunlight for extended periods.

7. Troubleshooting

If you experience problems with your subwoofer, consult the following table before contacting service personnel.

Problem	Possible Cause	Solution
No sound from subwoofer	Power cable not connected or loose. Subwoofer not powered on (main switch or auto-standby). Audio input cable not connected or faulty. Volume control set too low. Receiver's subwoofer output disabled or volume too low.	Check power cable connection and wall outlet. Ensure main power switch is ON. Send an audio signal to wake from standby. Check audio cable connections at both subwoofer and receiver. Try a different cable. Increase the subwoofer's volume control. Check receiver settings; ensure subwoofer output is enabled and its level is adequate.
Distorted or unclear bass	Volume set too high. Incorrect crossover frequency setting. Subwoofer placed too close to a wall or corner, causing boominess.	Reduce the subwoofer's volume. Adjust the crossover frequency for better blending with main speakers. Try repositioning the subwoofer slightly away from walls or corners.
Humming or buzzing sound	Ground loop issue. Faulty audio cable. Interference from other electronic devices.	Try plugging the subwoofer and receiver into the same power strip or wall outlet. Replace the audio cable. Move the subwoofer or other electronic devices further apart.
