4.2 Laidų jungtys
Refer to the wiring diagrams below for proper connections. Ensure all connections are secure and insulated.
5 pav. Iš arti 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.
- Maitinimas (BATT +12V): Connect to the positive terminal of the vehicle's battery via an appropriate fuse.
- Įžeminimas (GND): Connect to a solid, clean metal point on the vehicle's chassis.
- Nuotolinis įjungimas (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).
- Įvesties režimas: Select between 2CH or 4CH input mode based on your head unit's output.

- Reguliariai tikrinkite visas laidų jungtis, ar nėra sandarumo ir korozijos.
- Venkite atskleisti amplifier to harsh chemicals or solvents.
7. Problemų sprendimas
| Problema | Galima priežastis | Sprendimas |
|---|---|---|
| No Power / Protect LED On | Perdegęs saugiklis, blogas maitinimo / įžeminimo prijungimas, atjungtas nuotolinio valdymo laidas. | Check/replace fuse, verify power/ground connections, ensure remote wire is connected and receiving 12V. |
| Nėra garso išvesties | Incorrect input connections, speaker wires disconnected, gain too low. | Verify RCA/high-level inputs, check speaker connections and polarity, adjust gain settings. |
| Iškraipytas garsas | Gain set too high, incorrect crossover settings, speaker impedance mismatch. | Lower gain, adjust crossover filters, ensure speakers match amplifier's impedance rating. |
| Amplifier perkaitimas | Nepakankama ventiliacija, per maža varža, ilgalaikis naudojimas dideliais kiekiais. | Ensure proper airflow, check speaker impedance, reduce volume or allow cooling. |
