Opsætning og installation
Korrekt installation er afgørende for amplifier's performance and safety. It is recommended to have this unit installed by a qualified professional.
Monteringssted
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.
Ledningsforbindelser
- 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.
- Jordforbindelse: Tilslut jordkablet fra ampFastgør sikringen til en ren, umalet metaloverflade på køretøjets chassis. Sørg for en solid forbindelse med lav modstand.
- Fjerntænding: Tilslut fjernbetjeningsledningen fra amplifier to the remote output of your head unit. This will turn the amptænd og sluk for lyden med dit lydsystem.
- Lydindgang: Tilslut din lydkilde (hovedenhed) til 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).
- Højttaler output: Tilslut dine højttalere til amplifier's speaker output terminals. Ensure correct polarity (+ to + and - to -) for each speaker.
Betjeningsvejledning
Indledende opstart
After all connections are made, turn on your vehicle's ignition and then your audio head unit. The amplifier should power on, indicated by an LED indicator (if present).
Justering af forstærkningskontrol
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 amplivligere.
Opretholdelse
The Legacy LA120 amplifier requires minimal maintenance. Regular checks can help ensure its longevity.
- Rensning: Tør ydersiden af med jævne mellemrum amplifier with a soft, dry cloth to remove dust and debris. Do not use liquid cleaners or solvents.
- Ventilation: Ensure that the heat sink fins are not obstructed by dust or other materials. Proper airflow is essential for cooling.
- Tilslutningskontrol: Kontrollér lejlighedsvis alle ledningsforbindelser for at sikre, at de er fastgjorte og fri for korrosion. Løse forbindelser kan føre til dårlig ydeevne eller skader.
Fejlfinding
Hvis du oplever problemer med din ampLifier, se følgende almindelige problemer og løsninger:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen strøm / Amplifer tænder ikke | Sprunget sikring, løs strøm-/stel-/fjernbetjeningsledning, defekt fjernbetjeningsudgang til hovedenhed. | Kontroller den indbyggede sikring og 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. |
| Ingen lydudgang | No audio input signal, incorrect gain setting, speaker wires disconnected or shorted, amplifier i beskyttelsestilstand. | Check RCA/high-level input connections. Adjust gain. Inspect speaker wiring for shorts or disconnections. If amplifier is in protection, refer to protection section. |
| Forvrænget lyd | 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. |
| AmpOverophedning/beskyttelsestilstand for væske | Insufficient ventilation, low speaker impedance, prolonged high volume use, internal fault. | Sørg for korrekt luftgennemstrømning omkring 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. |
