5. コントロールと接続
5.1フロントパネル
The front panel provides access to all user-adjustable settings:
- サブレベル： Rotary knob to adjust the output level of the subwoofer signal. Range from 0 to 10.
- ステレオ/モノラル： Push-button switch to select between stereo (out) and mono (in) operation for the subwoofer output.
- 頻度： Rotary knob to set the crossover frequency, ranging from 36Hz to 200Hz. This determines the upper frequency limit for the subwoofer output.
- 位相（0°/180°）: Push-button switches for LEFT and RIGHT channels to invert the phase of the subwoofer output by 180 degrees. This helps in optimizing bass response relative to your main speakers.
- PWR LED： ユニットの電源がオンになると緑色に点灯します。
5.2 背面パネル
The rear panel houses all audio input and output connections, along with the power input:
- INPUT (L/R RCA): Stereo RCA inputs for connecting the audio source (e.g., preamplifier, receiver's line output).
- PASS THRU (L/R RCA): Stereo RCA outputs that provide the full-range input signal without any processing. Connect these to your main ampスピーカーまたはパワードスピーカー。
- SUB OUTPUT (L/R RCA): Stereo RCA outputs for the low-pass filtered signal. Connect these to your powered subwoofer(s) or a subwoofer amplifier。
- 力： Input jack for connecting the included 12V auxiliary power supply.
6. インストールとセットアップ
Follow these steps to integrate the SX95 into your audio system:
- 接続する前に、すべてのオーディオ機器の電源がオフになっていることを確認してください。
- Connect the line-level output from your audio source (e.g., preamplifier, receiver) to the INPUT (L/R RCA) jacks on the SX95 rear panel.
- 接続する PASS THRU (L/R RCA) outputs of the SX95 to the inputs of your main amplifier or powered speakers. This will carry the full-range signal to your main audio system.
- 接続する SUB OUTPUT (L/R RCA) jacks of the SX95 to the line-level inputs of your powered subwoofer(s) or subwoofer amplifier。
- Connect the included 12V auxiliary power supply to the 力 input on the SX95 rear panel, then plug the power supply into an AC outlet. The PWR LED on the front panel should illuminate.
- Power on your audio source, main amplifier/speakers, and subwoofer(s).
7. 操作
Once installed, adjust the controls on the front panel to optimize your subwoofer's performance:
- サブレベル： Start with the SUB LEVEL knob at a low setting (e.g., 3-4). Play some audio and gradually increase the level until the subwoofer blends seamlessly with your main speakers without overpowering them.
- 頻度： Adjust the FREQUENCY knob to set the crossover point. This should typically be set based on the frequency response of your main speakers and subwoofer. A common starting point is 80Hz, but experimentation is recommended to find the ideal blend for your specific setup and room acoustics.
- ステレオ/モノラル： If you are using a single subwoofer, press the STEREO/MONO button in for mono operation. If you are using two subwoofers and wish to maintain stereo separation for the low frequencies, leave the button out for stereo operation.
- 位相（0°/180°）: The phase switches help align the subwoofer's output with your main speakers. Listen to music with strong bass and try both 0° and 180° settings for each channel. Choose the setting that provides the most impactful and coherent bass response. Often, the correct phase will result in a fuller, more defined bass sound.
8. メンテナンス
The ROLLS SX95 requires minimal maintenance. To ensure longevity and optimal performance:
- 本体は乾いた柔らかい布で拭いて清潔に保ってください。
- 強力な化学薬品や研磨剤入りの洗剤の使用は避けてください。
- 過熱を防ぐために、ユニットの周囲に十分な換気を確保してください。
- ユニットを極端な温度や湿度にさらさないでください。
9。 トラブルシューティング
| 問題 | 考えられる原因 | 解決 |
|---|---|---|
| 電源なし（PWR LED オフ） | Power supply not connected or faulty; AC outlet not active. | Check power supply connection to unit and outlet. Test outlet with another device. |
| サブウーファーの音が出ない | Incorrect connections; SUB LEVEL too low; subwoofer powered off or faulty. | Verify all RCA connections. Increase SUB LEVEL. Ensure subwoofer is powered on and functioning. |
| Main speakers have no sound | Incorrect PASS THRU connections; main amplifier powered off or faulty. | メインを確保する amplifier/speakers are connected to the SX95's PASS THRU outputs. Check main ampライフパワー。 |
| 弱い、または濁った低音 | Incorrect FREQUENCY or PHASE settings. | Adjust FREQUENCY knob to find optimal crossover point. Experiment with PHASE (0°/180°) settings for both channels. |
| ハムまたはノイズ | グランドループ、不良ケーブル、干渉。 | Ensure all components are on the same electrical circuit. Try different RCA cables. Keep audio cables away from power cables. |
