4.2 Kablingstilkoblinger
Refer to the wiring diagrams below for proper connections. Ensure all connections are secure and insulated.
Figur 5: Nærbilde 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.
- Strøm (BATTERI +12V): Connect to the positive terminal of the vehicle's battery via an appropriate fuse.
- Bakke (GND): Connect to a solid, clean metal point on the vehicle's chassis.
- Fjernstyrt påslåing (REM): Koble til fjernutgangen på hovedenheten eller en tenningskoblet 12V-kilde.
- Speaker Outputs (CH1-CH4): Connect your speakers to the corresponding channels. Ensure correct polarity and impedance matching (2-4 ohms stable).
- Inndatamodus: 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.
- Lavnivåinngang (RCA): Koble RCA-kabler fra hovedenhetens pre-utganger til amplierens RCA-innganger.
- Inndata på høyt nivå: 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. Betjening av Amplivligere
5.1 Forsterkningsjustering
Adjust the GAIN knobs for each channel to match the output voltage på hovedenheten. Start med minimumsforsterkning og øk sakte til ønsket volum oppnås uten forvrengning.
5.2 Delefilterinnstillinger
The VADM4v2 features selectable crossover modes and variable filters:

- FULL: Full-range output, no filtering applied.
- HPF (høypassfilter): Allows frequencies above the set point to pass through. Useful for full-range speakers to prevent distortion from low bass.
- LPF (lavpassfilter): 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. Vedlikehold
To ensure longevity and optimal performance of your NVX VADM4v2 amplivligere:
- Behold ampFjerneren er ren og fri for støv og rusk. Bruk en myk, tørr klut til rengjøring.
- Sørg for tilstrekkelig luftstrøm rundt ampkjøler for å forhindre overoppheting.
- Kontroller regelmessig alle ledningsforbindelser for tetthet og korrosjon.
- Unngå å utsette amplifier to harsh chemicals or solvents.
7. Feilsøking
| Problem | Mulig årsak | Løsning |
|---|---|---|
| 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. |
| Ingen lydutgang | Incorrect input connections, speaker wires disconnected, gain too low. | Verify RCA/high-level inputs, check speaker connections and polarity, adjust gain settings. |
| Forvrengt lyd | Gain set too high, incorrect crossover settings, speaker impedance mismatch. | Lower gain, adjust crossover filters, ensure speakers match ampLifierens impedansvurdering. |
| AmpOveroppheting av væske | Utilstrekkelig ventilasjon, for lav impedans, langvarig bruk med høyt volum. | Ensure proper airflow, check speaker impedance, reduce volume or allow cooling. |
