การตั้งค่า
1. การแกะกล่อง
Carefully remove the SDS12 subwoofer from its packaging. Retain all packing materials for future transport or storage. Inspect the subwoofer for any signs of damage during transit. If damage is found, contact your dealer immediately.
2 การวาง
The placement of your subwoofer significantly impacts its performance. Experiment with different locations in your room to find the optimal spot. Consider the following:
- ตำแหน่งมุม: Placing the subwoofer in a corner often maximizes bass output due to room gain, but can sometimes lead to boomy or uneven bass.
- ตำแหน่งผนัง: Placing the subwoofer along a wall, away from corners, can provide a more balanced bass response.
- Near Listening Position: Placing the subwoofer closer to your primary listening position can sometimes improve bass clarity and impact.
- หลีกเลี่ยงสิ่งกีดขวาง: Ensure the subwoofer's driver is not obstructed by furniture or other objects.
3. การเชื่อมต่อ
ก่อนที่จะทำการเชื่อมต่อใดๆ โปรดตรวจสอบให้แน่ใจว่าอุปกรณ์เสียงทั้งหมดปิดอยู่และถอดปลั๊กออกจากเต้ารับไฟฟ้าแล้ว
- LFE/Subwoofer Output: Connect an RCA cable from the LFE or Subwoofer Output of your AV receiver or pre-amplifier to the LFE Input on the SDS12 subwoofer. This is the recommended connection for most home theater systems.
- ช่องรับสัญญาณสเตอริโอ RCA: If your receiver does not have a dedicated LFE output, connect stereo RCA cables from the pre-out (left and right) of your receiver to the Left and Right Line Inputs on the SDS12.
- การเชื่อมต่อไฟฟ้า: Once audio connections are made, connect the supplied power cord to the SDS12's power inlet and then to a grounded AC power outlet.
การดำเนินงาน
1. การเปิด/ปิดเครื่อง
The SDS12 features an auto-sensing power mode. When set to 'Auto', the subwoofer will automatically turn on when an audio signal is detected and enter standby mode after a period of inactivity. You can also manually turn the subwoofer on or off using the power switch on the rear panel.
2. การตั้งค่าเริ่มต้น
After connecting and powering on your subwoofer, adjust the following controls:
- ปริมาณ/กำไร: Start with the volume control at its lowest setting. Play some audio and slowly increase the volume until the subwoofer blends seamlessly with your main speakers. The bass should be felt, not localized.
- ความถี่ครอสโอเวอร์: If using the LFE input, your AV receiver will manage the crossover. If using stereo RCA inputs, set the crossover frequency on the subwoofer to match the low-frequency extension of your main speakers. A common starting point is 80Hz.
- การควบคุมเฟส: The phase control (0° or 180°) helps ensure the subwoofer's output is in phase with your main speakers. Experiment with both settings while listening to music with strong bass. Choose the setting that provides the most impactful and cohesive bass.
3 การเพิ่มประสิทธิภาพการทำงาน
Fine-tuning your subwoofer can significantly enhance your listening experience. Consider using your AV receiver's automatic room correction system (e.g., Audyssey, MCACC, YPAO) if available. For manual adjustments, listen to a variety of music and movie content to ensure the bass is tight, articulate, and well-integrated with your system.
การซ่อมบำรุง
การทำความสะอาด
To clean the cabinet of your SDS12 subwoofer, use a soft, dry cloth. For stubborn marks, a slightly damp cloth can be used, followed by a dry cloth. Avoid using harsh chemicals, abrasive cleaners, or solvents, as these can damage the finish.
พื้นที่จัดเก็บ
If you need to store the subwoofer for an extended period, disconnect it from power, clean it, and ideally repack it in its original packaging to protect it from dust and physical damage. Store in a cool, dry place.
