NVX XPLOC4 4チャンネル調整可能ライン出力コンバーター ユーザーマニュアル

1. はじめに

The NVX XPLOC4 is a 4-channel adjustable line output converter designed to integrate an aftermarket amplifier with a factory or aftermarket stereo system that lacks dedicated RCA outputs. It converts high-level speaker signals into low-level RCA signals, enabling the addition of external amplifiers for enhanced audio performance. This unit features a 6:1 step-down ratio, adjustable gain output, and a DC amplifier turn-on trigger.

2. 主な特徴

• 4チャンネル操作: Supports front and rear speaker channels for comprehensive ampライファイアー統合。
• Adjustable Gain Output: Allows precise matching of the output signal to the ampライファイアの入力感度。
• High Power Input Capability: Handles up to 600 watts total (150 watts per channel) from the source unit.
• DC Amplifier Turn-On Trigger: Provides a remote turn-on signal for the amplifier, eliminating the need for a separate remote wire from the head unit.
• Low Distortion Design: Engineered for high-quality audio signal conversion with minimal distortion.

5.2 接続手順

1. バッテリーを外します: 作業を始める前に、電気的なショートを防ぐために、車両のバッテリーのマイナス端子を外してください。
2. スピーカーワイヤーを識別します。 Locate the speaker output wires from your factory or aftermarket head unit. These will be connected to the input side of the XPLOC4's wiring harness.
3. スピーカー入力を接続します: Connect the corresponding speaker wires from your head unit to the input wires of the XPLOC4 harness. Match positive to positive and negative to negative for each channel (Front Left, Front Right, Rear Left, Rear Right).
4. 電源とアースの接続:
   • 接続する +12V (Yellow) wire from the XPLOC4 to a constant +12V power source.
   • 接続する GND（黒） wire from the XPLOC4 to a solid chassis ground point.
5. Remote Turn-On Output: The XPLOC4 provides a Remote (Blue) output wire. Connect this wire to the remote turn-on input of your aftermarket amplifier. This signal will turn on the amplifier when the head unit is active.
6. RCA Output Connections: Connect the RCA output cables from the XPLOC4 to the RCA input jacks on your aftermarket amplifier. Ensure Front Left/Right and Rear Left/Right channels are correctly matched.

6. 操作手順

6.1 Adjusting Gain Levels

The NVX XPLOC4 features adjustable gain controls for each channel pair (Front and Rear). These controls allow you to match the output level of the XPLOC4 to the input sensitivity of your amplifier, preventing distortion and optimizing sound quality.

1. 初期設定： Turn the gain adjustment screws on the XPLOC4 all the way down (counter-clockwise).
2. Ampリファイアゲイン： Set the gain controls on your aftermarket amplifier to their minimum setting.
3. ヘッドユニットの容量: Turn your head unit volume up to about 75-80% of its maximum level.
4. Adjust XPLOC4 Gain: Slowly turn the gain adjustment screws on the XPLOC4 clockwise until the red LED indicator light just begins to flicker or illuminate steadily. This indicates that the signal is approaching clipping. Back off slightly until the LED is off or only flickers minimally.
5. 調整する Ampリファイアゲイン： Once the XPLOC4 gains are set, slowly increase the gain on your amplifier until the desired volume and sound quality are achieved without audible distortion.

The red LED indicator on the XPLOC4 serves as a clipping indicator. If it illuminates brightly or constantly, the input signal is too high, and distortion may occur. Reduce the head unit volume or the XPLOC4 gain until the LED is off or only flickers occasionally on peak notes.

7. メンテナンス

The NVX XPLOC4 is designed for reliable operation and requires minimal maintenance. Ensure the unit is installed in a dry location, away from excessive heat and direct sunlight. Periodically check all wiring connections to ensure they remain secure and free from corrosion.

• クリーニング： 本体の外側を清掃する際は、柔らかく乾いた布をご使用ください。刺激の強い化学薬品や研磨剤入りの洗剤は使用しないでください。
• 換気： Ensure the unit has adequate ventilation to prevent overheating, although passive cooling is generally sufficient for this device.
