4.2 Kabelverbindungen
Refer to the wiring diagrams below for proper connections. Ensure all connections are secure and insulated.
Abbildung 5: Nahaufnahme view of the power input and speaker output terminals on the NVX VADM4v2 amplifier. Connections include GND (Ground), REM (Remote Turn-On), +12V (Power), and speaker outputs for CH1-CH4.
- Stromversorgung (BATT +12V): Connect to the positive terminal of the vehicle's battery via an appropriate fuse.
- Masse (GND): Connect to a solid, clean metal point on the vehicle's chassis.
- Ferneinschaltung (REM): Connect to the remote output of your head unit or an ignition-switched 12V source.
- Lautsprecherausgänge (CH1-CH4): Connect your speakers to the corresponding channels. Ensure correct polarity and impedance matching (2-4 ohms stable).
- Eingabemodus: Select between 2CH or 4CH input mode based on your head unit's output.

4.3 Input Signal Connection
The VADM4v2 supports both low-level (RCA) and high-level inputs.
- Eingang mit niedrigem Pegel (RCA): Verbinden Sie die Vorverstärkerausgänge Ihres Autoradios mit RCA-Kabeln mit dem/der/dem ampRCA-Eingänge des Verstärkers.
- High-Level-Eingang: If your head unit does not have RCA outputs, use the provided high-level input harnesses to connect directly to your head unit's speaker outputs.
5. Bedienung des Ampschwerer
5.1 Verstärkungseinstellung
Adjust the GAIN knobs for each channel to match the output voltagStellen Sie die Verstärkung an Ihrem Autoradio ein. Beginnen Sie mit der minimalen Verstärkungseinstellung und erhöhen Sie diese langsam, bis die gewünschte Lautstärke ohne Verzerrungen erreicht ist.
5.2 Frequenzweicheneinstellungen
The VADM4v2 features selectable crossover modes and variable filters:

- VOLL: Full-range output, no filtering applied.
- HPF (Hochpassfilter): Allows frequencies above the set point to pass through. Useful for full-range speakers to prevent distortion from low bass.
- LPF (Tiefpassfilter): Allows frequencies below the set point to pass through. Ideal for subwoofers.
- FREQ (Frequency Knob): Adjusts the cutoff frequency for HPF or LPF modes (40-400 Hz).

7. Fehlerbehebung
| Problem | Mögliche Ursache | Lösung |
|---|---|---|
| No Power / Protect LED On | Blown fuse, poor power/ground connection, remote wire disconnected. | Check/replace fuse, verify power/ground connections, ensure remote wire is connected and receiving 12V. |
| Keine Tonausgabe | Incorrect input connections, speaker wires disconnected, gain too low. | Verify RCA/high-level inputs, check speaker connections and polarity, adjust gain settings. |
| Verzerrter Klang | Gain set too high, incorrect crossover settings, speaker impedance mismatch. | Lower gain, adjust crossover filters, ensure speakers match ampImpedanzwert des Verstärkers. |
| AmpVerstärkerüberhitzung | Insufficient ventilation, impedance too low, prolonged high-volume use. | Ensure proper airflow, check speaker impedance, reduce volume or allow cooling. |
