Configuració i instal·lació
La instal·lació correcta és crucial per a la amplifier's performance and safety. It is recommended to have this unit installed by a qualified professional.
Ubicació de muntatge
Choose a mounting location that is dry, well-ventilated, and away from direct sunlight or heat sources. Ensure sufficient airflow around the amplifier's heat sink. The amplifier is designed for freestanding mount.
Connexions de cablejat
- Power Connection (12V): Connect the main power cable from the amplifier to the positive terminal of the vehicle's battery. Use appropriate gauge wire and an inline fuse (not supplied) as close to the battery as possible.
- Connexió a terra: Connecteu el cable de terra del ampl'adaptador a una superfície metàl·lica neta i sense pintar del xassís del vehicle. Assegureu-vos que la connexió sigui sòlida i de baixa resistència.
- Encès remot: Connecteu el cable d'encesa remot des del amplifier to the remote output of your head unit. This will turn the ampengegueu i apagau l'activador amb el vostre sistema d'àudio.
- Entrada d'àudio: Connecteu la font d'àudio (unitat principal) a amplifier's input terminals. Use either the high-level inputs (speaker wire from head unit) or low-level inputs (RCA cables from head unit's pre-outs).
- Sortida de l'altaveu: Connecteu els vostres altaveus al amplifier's speaker output terminals. Ensure correct polarity (+ to + and - to -) for each speaker.
Instruccions de funcionament
Encesa inicial
After all connections are made, turn on your vehicle's ignition and then your audio head unit. The ampEl dispensador s'hauria d'encendre, cosa que s'indica amb un indicador LED (si n'hi ha).
Ajust del control de guany
The variable gain control allows you to match the amplifier's input sensitivity to the output level of your head unit. Start with the gain control at its minimum setting. Play a familiar piece of music at a moderate volume on your head unit. Slowly increase the amplifier's gain control until you hear distortion, then back it off slightly until the sound is clear. Avoid setting the gain too high, as this can lead to distorted audio and potential damage to speakers or the ampmés viu.
Manteniment
The Legacy LA120 amplifier requires minimal maintenance. Regular checks can help ensure its longevity.
- Neteja: Netegeu periòdicament l'exterior de la amplifier with a soft, dry cloth to remove dust and debris. Do not use liquid cleaners or solvents.
- Ventilació: Ensure that the heat sink fins are not obstructed by dust or other materials. Proper airflow is essential for cooling.
- Comprovació de la connexió: De tant en tant, comproveu totes les connexions del cablejat per assegurar-vos que estiguin ben fixades i sense corrosió. Les connexions soltes poden provocar un rendiment deficient o danys.
Resolució de problemes
Si teniu problemes amb el vostre amplifier, consulteu els següents problemes i solucions habituals:
| Problema | Causa possible | Solució |
|---|---|---|
| Sense alimentació / AmpEl lificador no s'encén | Blown fuse, loose power/ground/remote wire, faulty head unit remote output. | Comproveu el fusible en línia i amplifier fuses. Verify all power, ground, and remote connections are secure and have proper voltage. Test remote wire for 12V when head unit is on. |
| Sense sortida de so | No audio input signal, incorrect gain setting, speaker wires disconnected or shorted, amplificador en mode de protecció. | Check RCA/high-level input connections. Adjust gain. Inspect speaker wiring for shorts or disconnections. If amplifier is in protection, refer to protection section. |
| So distorsionat | Gain set too high, poor ground connection, speaker impedance mismatch, damaged speakers. | Reduce gain setting. Ensure a solid ground connection. Verify speaker impedance matches amplifier's capabilities. Test speakers individually. |
| AmpMode de protecció / sobreescalfament del lificador | Insufficient ventilation, low speaker impedance, prolonged high volume use, internal fault. | Assegureu-vos que el flux d'aire al voltant de amplifier. Check speaker impedance. Reduce volume. If problem persists, seek professional service. The 3-way protection system (short/thermal/overload) will activate to prevent damage. |
