3. 設定

3.1 安置

Optimal placement of the Klipsch Sub-12HG subwoofer is crucial for sound quality. Due to its down-firing driver and rear-firing port, it is designed to produce increased bass response with low distortion, filling the room with rich bass. Experiment with different locations in your room to find the best acoustic integration. Corner placement often enhances bass output.

3.2 連接

The Sub-12HG offers versatile connection options to integrate with various audio systems:

• 線路電平（RCA）輸入： Connect your receiver's subwoofer output (LFE or Sub Out) to the LFE input on the subwoofer using an RCA cable. For stereo receivers without a dedicated subwoofer output, use both the left and right line-level inputs.
• 揚聲器級輸入： For receivers without line-level outputs, connect the speaker wires from your amplifier's main left and right channels to the speaker-level inputs on the subwoofer. Then, connect your main speakers to the speaker-level outputs on the subwoofer.

3.3 電源連接

Connect the provided power cord to the subwoofer's power input and then to a standard 120V AC wall outlet.

4. 操作說明

The Klipsch Sub-12HG features several controls for fine-tuning its performance to your listening environment:

• 增益/音量控制： 調整重低音的整體輸出音量。先從較低的設定開始，然後逐漸增加，直到低音與主揚聲器完美融合。
• 低通交叉： The built-in, steep-slope low-pass crossover is continuously adjustable from 40 to 120Hz. This control determines the highest frequency the subwoofer will reproduce. Set it to match the low-frequency capabilities of your main speakers. If your receiver has a built-in crossover, set the subwoofer's crossover to its highest setting (LFE) and manage the crossover through your receiver.
• Phase Control (0-180 degrees): This control helps acoustically integrate the subwoofer with your other speakers. Experiment with both 0 and 180-degree settings to find the one that provides the most impactful and coherent bass response at your listening position.
• 自動電源功能： The subwoofer includes an "auto power" feature, allowing it to turn itself on and off automatically based on the presence or absence of an audio signal. A blue/red dual-color LED display on the front indicates whether the unit is on (blue) or in standby mode (red).

5、維護保養

To ensure the longevity and optimal performance of your Klipsch Sub-12HG subwoofer, follow these maintenance guidelines:

• 打掃： 用柔軟的乾布清潔櫥櫃。避免使用研磨性清潔劑或溶劑。
• 放置： 請將重低音遠離陽光直射、熱源和潮濕環境。確保設備周圍通風良好。
• 處理： When moving the subwoofer, lift it carefully to avoid damage to the cabinet or internal components.

6。 故障排除

If you experience issues with your subwoofer, consult the following common troubleshooting steps:

• 無聲音：
  • Check all power connections and ensure the subwoofer is plugged into a live outlet.
  • Verify that the "auto power" feature is not preventing the unit from turning on (LED should be blue when active).
  • Confirm audio cables are securely connected to both the receiver/amplifier和低音炮。
  • Check the gain/volume control on the subwoofer and your receiver; ensure they are not set to minimum.
• 失真或轟鳴的低音：
  • Adjust the gain/volume control on the subwoofer to a lower level.
  • Experiment with the low-pass crossover setting to ensure it integrates well with your main speakers.
  • Try adjusting the phase control (0 or 180 degrees) to find the setting that provides the tightest bass.
  • Relocate the subwoofer to a different position in the room to minimize room acoustics issues.
• 嗡嗡聲：
  • 確保所有音訊線纜均有適當的屏蔽層並連接牢固。
  • 試著將重低音插入不同的電源插座，最好是不同電路上的插座。
  • If using RCA connections, try a different RCA cable.
