NVX XLOC66X 6-Channel Line Output Converter

1. Einleitung

The NVX XLOC66X is a high-voltage active line output converter designed to seamlessly integrate aftermarket amplifiers with factory car audio systems. Modern factory head units often lack RCA outputs, which are essential for connecting aftermarket amplifiers. This device converts high-level speaker signals from your factory stereo into low-level RCA signals, allowing for a clean and reliable connection to your amplifier. It features 6 input channels and 6 output channels, impedance matching, and a remote level control for enhanced audio system flexibility.

Please read this manual thoroughly before installation and operation to ensure proper use and optimal performance of your NVX XLOC66X.

2. Hauptmerkmale

• 6-Channel Speaker Level Inputs: Accepts high-level signals from up to six speaker channels.
• 6-Channel RCA Outputs: Provides low-level RCA outputs for front, rear, and subwoofer amplifier-Verbindungen.
• Hohe Lautstärketage Handling: Capable of handling up to 40V (400 watts RMS) speaker level inputs.
• Hohe Ausgangsvoltage: Delivers up to 9.5 Volts of output for strong signal to amplifizierer.
• Automatisches Einschalten: Features automatic turn-on via DC offset detection or audio signal detection, eliminating the need for a dedicated remote wire from the head unit.
• Load Selection Switch: Adjustable impedance (20, 60, or 20K ohms) to prevent factory stereo shutdown issues.
• Wired Remote Bass Level Control: Included for convenient adjustment of subwoofer output level.
• LED Clip Indicator: Provides visual feedback for optimal gain setting and to prevent signal clipping.

3. Einrichtung und Installation

3.1 Sicherheitsvorkehrungen

• Always disconnect the vehicle's negative battery terminal before starting any electrical installation.
• Stellen Sie sicher, dass alle Kabel ordnungsgemäß isoliert und befestigt sind, um Kurzschlüsse und Beschädigungen zu vermeiden.
• Wenn Sie sich bei irgendeinem Teil des Installationsprozesses unsicher sind, wenden Sie sich an einen professionellen Car-Audio-Einbauer.

3.2 Mounting the XLOC66X

Choose a secure, dry location for mounting the XLOC66X, away from excessive heat or moisture. Ensure adequate ventilation around the unit. Use the provided mounting screws to secure the device.

3.3 Kabelverbindungen

The XLOC66X features a terminal block for power, ground, remote, and speaker level inputs, and RCA jacks for low-level outputs.

• 12V (Power): Connect to a constant 12V power source from the vehicle's battery. Use an appropriate gauge wire and an inline fuse (not included) near the battery.
• GND (Masse): Connect to a solid chassis ground point in the vehicle. Ensure a clean, paint-free metal-to-metal connection.
• REM IN (Remote Input): Connect to the remote turn-on output of your head unit if available. This is optional if using DC offset or audio detection for turn-on.
• REM OUT (Remote-Ausgang): Provides a 12V remote turn-on signal for your aftermarket amplifizierer.
• CH1+ to CH6+ (Speaker Level Inputs): Connect these terminals to the corresponding positive and negative speaker wires from your factory head unit or factory ampVerstärker. Achten Sie auf die richtige Polarität.
• RCA Outputs (Front, Rear, Sub): Connect these to the RCA inputs of your aftermarket amplifier(s) using high-quality RCA cables.
• Remote Bass Knob Input: Connect the wired remote bass level control to the dedicated port on the XLOC66X.

3.4 Initial Settings and Adjustments

Before powering on, configure the switches on the XLOC66X:

• Turn-on Mode Switch: Wählen Sie zwischen DC (DC offset detection), AUD (audio signal detection), or REM (remote wire input). Choose the mode that best suits your vehicle's factory system.
• Load Select Switch (CH1-CH4 & CH5-CH6): Adjust the impedance presented to the factory stereo. Options are 20 Ω, 60 Ω, oder 20 KΩ. Start with 20KΩ if unsure, and adjust if the factory stereo exhibits shutdown issues.
• Eingangsmodusschalter: Wählen 4 Kanäle for 4-channel input or 6 Kanäle for 6-channel input, depending on your factory system's output.
• Ground Isolation Switch: Optionen sind Masse (common ground), ISO (isolated ground), or 200 Ω (200 ohm isolated ground). Use this to address ground loop noise or alternator hum. Start with GND and switch to ISO or 200Ω if noise is present.
• LPF (Low Pass Filter) Switch: Eingestellt auf ON if you want the subwoofer output to have a low-pass filter applied, or AUS wenn Ihr amplifier handles the LPF.
• Boost-Regler: This controls the bass boost for the subwoofer output. Start at 0 dB und nach Bedarf anpassen.
• Gain Knobs (Front, Rear, Sub): These adjust the output level of the XLOC66X. Start at minimum (MIN) and adjust carefully during the operating phase.

4.1 Setting Gains

Proper gain setting is crucial for optimal sound quality and to prevent distortion. The XLOC66X features LED clip indicators for each output channel (Front, Rear, Sub).

1. Turn the gain knobs on the XLOC66X to their minimum (MIN) position.
2. Turn the gain knobs on your aftermarket amplifier(s) to their minimum setting.
3. Play a test tone (e.g., a 0dB sine wave at 1kHz for full-range, or 50Hz for subwoofer) at about 75% of your head unit's maximum volume.
4. Slowly increase the gain knob on the XLOC66X for one channel (e.g., Front) until the corresponding LED clip indicator just begins to flicker. Then, back off slightly until the LED is off. Repeat for Rear and Sub channels.
5. Once the XLOC66X gains are set, proceed to set the gains on your aftermarket amplifier(s) according to their respective manuals, ensuring no clipping occurs at the amplifiertage.

4.2 Using the Remote Bass Control

The included wired remote bass level control allows you to conveniently adjust the output level of the subwoofer channel from your listening position. Connect it to the 'REMOTE' port on the XLOC66X. Rotate the knob to increase or decrease the subwoofer output.

4.3 Bass Boost and Low Pass Filter

The LPF switch and Boost knob affect the subwoofer output. If your subwoofer amplifier has its own low-pass filter, it is generally recommended to set the XLOC66X LPF to OFF. Use the Boost knob to add a subtle bass enhancement if desired, but avoid excessive boosting which can lead to distortion.

5. Wartung

The NVX XLOC66X requires minimal maintenance. Keep the unit clean and free from dust and debris. Periodically check all wiring connections to ensure they are secure and free from corrosion. Avoid exposing the unit to extreme temperatures or moisture.
