4.2 Ožičenje
Refer to the wiring diagrams below for proper connections. Ensure all connections are secure and insulated.
Slika 5: Krupni plan 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.
- Napajanje (BATERIJA +12V): Connect to the positive terminal of the vehicle's battery via an appropriate fuse.
- Uzemljenje (GND): Connect to a solid, clean metal point on the vehicle's chassis.
- Daljinsko uključivanje (REM): Connect to the remote output of your head unit or an ignition-switched 12V source.
- Speaker Outputs (CH1-CH4): Connect your speakers to the corresponding channels. Ensure correct polarity and impedance matching (2-4 ohms stable).
- Način unosa: 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.
- Ulaz niskog nivoa (RCA): Connect RCA cables from your head unit's pre-outs to the ampRCA ulazi.
- Ulaz visokog nivoa: 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.

- PUNO: Full-range output, no filtering applied.
- HPF (High-Pass filter): Allows frequencies above the set point to pass through. Useful for full-range speakers to prevent distortion from low bass.
- LPF (niskopropusni filter): 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).
6. Održavanje
To ensure longevity and optimal performance of your NVX VADM4v2 ampdizalica:
- Zadrži ampČistite filter, bez prašine i ostataka. Za čišćenje koristite meku, suhu krpu.

7. Otkrivanje problema
| Problem | Mogući uzrok | Rješenje |
|---|---|---|
| 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. |
| Nema izlaza zvuka | Incorrect input connections, speaker wires disconnected, gain too low. | Verify RCA/high-level inputs, check speaker connections and polarity, adjust gain settings. |
| Distorted Sound | Gain set too high, incorrect crossover settings, speaker impedance mismatch. | Lower gain, adjust crossover filters, ensure speakers match ampnazivna impedancija otpornika. |
| AmpPregrijavanje | Nedovoljna ventilacija, preniska impedancija, produžena upotreba velike količine zvuka. | Ensure proper airflow, check speaker impedance, reduce volume or allow cooling. |
