Avoid placing it directly against a wall or in a cabinet without proper ventilation.

1. RCA Line-Level Input: Connect an RCA cable from the LFE (Low-Frequency Effects) output or Subwoofer Pre-Out on your receiver/amplifier to the 'LINE IN L/R' input on the subwoofer. If your receiver has a single LFE output, use a Y-adapter or connect to either the L or R input.
2. Connexió d'alimentació: Once audio connections are made, connect the supplied power cord to the subwoofer's AC inlet and then to a suitable wall outlet.

6. Funcionament

The KLH Stratton subwoofer features several controls on its rear panel to fine-tune its performance with your audio system.

• VOLUM: 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.
• FASE (0°/180°): This switch helps to match the subwoofer's output phase with your main speakers. If the bass sounds weak or hollow, try flipping this switch. The correct setting will result in stronger, more impactful bass.
• CROSSOVER (40Hz-160Hz): This control determines the highest frequency the subwoofer will reproduce. Set it to blend with the low-frequency capabilities of your main speakers. A common starting point is around 80Hz, but adjust based on your system and room acoustics.
• ENCÈS (ENCÈS/APAGAT/AUTO):
  • ACTIVITAT: El subwoofer roman encès contínuament.
  • DESACTIVAT: El subwoofer està apagat.
  • AUTOMÀTIC: The subwoofer will automatically turn on when an audio signal is detected and enter standby mode after a period of inactivity.
• TRIGGER (12V): For advanced home theater systems, this input allows the subwoofer to be turned on/off automatically by a 12V trigger signal from your receiver or processor.

7. Manteniment

Proper care will ensure the longevity and performance of your subwoofer.

• Neteja: Use a soft, dry cloth to wipe the cabinet. Avoid using abrasive cleaners, waxes, or solvents.
• Pols: Regularly dust the unit to prevent accumulation, especially around the driver and rear panel.
• Medi ambient: Avoid exposing the subwoofer to extreme temperatures, direct sunlight, or high humidity.
