1. Einleitung

This manual provides detailed instructions for the installation, operation, and maintenance of your NVX XAD12 Monoblock Car Audio Amplifier. The XAD12 is a 1500W RMS, 1-Ohm stable, full bridge Class D amplifier designed for high-power car audio applications. Please read this manual thoroughly before attempting installation or operation to ensure proper use and to prevent damage.

2. Sicherheitshinweise

• Vor Beginn jeglicher elektrischer Arbeiten muss immer der Minuspol der Fahrzeugbatterie abgeklemmt werden.
• Achten Sie darauf, dass alle Kabel ordnungsgemäß verlegt und befestigt sind, um Beschädigungen durch scharfe Kanten oder bewegliche Teile zu vermeiden.
• Verwenden Sie für die Strom- und Erdungsanschlüsse die im Installationsabschnitt angegebenen Kabel mit dem entsprechenden Querschnitt.
• Install fuses as close to the battery as possible to protect against short circuits.
• Vermeiden Sie die Montage der ampVerstärker an Orten, die direkter Sonneneinstrahlung, übermäßiger Hitze, Feuchtigkeit oder Staub ausgesetzt sind.
• Ziehen Sie einen professionellen Installateur zu Rate, wenn Sie sich bei irgendeinem Teil des Installationsprozesses unsicher sind.
• Bedienung des amplifier at extreme volumes for extended periods can cause hearing damage.

3. Einrichtung und Installation

Proper installation is crucial for optimal performance and safety. The NVX XAD12 features a Pulse Width Modulated (PWM) MOSFET power supply and soft start turn-on circuitry.

3.1 Montage der Ampschwerer

The XAD12 is designed for surface mount installation. Choose a location that provides adequate ventilation and is protected from moisture and direct heat. Ensure there is sufficient space around the ampfür die Luftzirkulation.

3.2 Stromanschlüsse

Schließen Sie die Strom-, Erdungs- und Ferneinschaltleitungen an die amplifier's power input terminal block.

• +12V (Stromversorgung): Connect a heavy-gauge power cable (e.g., 4 AWG or larger for 1500W RMS) directly from the positive terminal of the vehicle's battery. Install an appropriate fuse (not included) within 18 inches of the battery.
• REM IN (Remote Turn-On): Connect a 18-gauge wire from the remote turn-on output of your head unit or other switched 12V source.
• GND (Masse): Connect a heavy-gauge ground cable (same gauge as power) to a clean, unpainted metal surface of the vehicle's chassis. Ensure a solid electrical connection.

3.3 Speaker Output Connection

Connect your subwoofer(s) to the speaker output terminals. The XAD12 is 1-Ohm stable, allowing for flexible wiring configurations. Ensure the total impedance of your connected speakers does not fall below 1 Ohm.

3.4 RCA-Ein-/Ausgangsanschlüsse

Connect the RCA input cables from your head unit's subwoofer output to the amplifier's INPUT RCA jacks. If daisy-chaining multiple amplifiers, use the OUTPUT RCA jacks to send the signal to the next ampschwerer.

4. Bedienung des Ampschwerer

Sobald alle Verbindungen hergestellt und überprüft sind, können Sie Ihr System einschalten und die Einstellungen vornehmen. ampreglereinstellungen.

4.1 Erste Inbetriebnahme und Verstärkungseinstellung

• Schalten Sie Ihr Autoradio ein. amplifier should power on (indicated by the power LED).
• Legen Sie die amplifier's GAIN control to its minimum position.
• Play a familiar music track with a strong bass presence at about 75% of your head unit's maximum volume.
• Slowly increase the GAIN control on the amplifier until you hear distortion, then back it off slightly. The POWER/CLIP/PROTECT indicator can assist in setting the gain without clipping.

4.2 Crossover and Bass Boost Adjustments

• LPF (Tiefpassfilter): Adjust this control to filter out high frequencies from your subwoofer. A common starting point is 80-100 Hz.
• SUBSONIC Filter: This filter removes extremely low frequencies that are below the audible range and can cause damage to your subwoofer. Set it slightly below your subwoofer's port tuning frequency or around 20-30 Hz.
• BASS-BOOST: Use this control sparingly to enhance bass output. Excessive bass boost can lead to distortion and potential speaker damage. Start at 0dB and increase gradually if desired.
