Nøglekomponenter:
- Power Terminals (B+, R, B-): Connect to battery positive, remote turn-on, and battery negative/ground respectively.
- Speaker Terminals (L+, L-, R+, R-): Connect to left and right speakers.
- Høj input: For connecting to head units without RCA outputs.
- Lav indgang (RCA): Til tilslutning til hovedenheder med RCA pre-outs.
- Niveaukontrol: Justerer indgangsfølsomheden for amplivligere.
- Filter Switch: Selects between Full Range and Low Pass filter modes.
Installation og opsætning
1. Montering af Amplivligere
Choose a secure, dry location with adequate ventilation. Avoid mounting near heat sources or in direct sunlight. Use the provided mounting hardware to secure the amplivligere.
2. Ledningsforbindelser
Ensure the vehicle's battery is disconnected before making any wiring connections.
Strømforbindelser:
- B+ (Positive): Connect to the vehicle's positive battery terminal via a fuse (not included, recommended 15A-20A).
- B- (Ground): Connect to a clean, unpainted metal surface on the vehicle chassis. Ensure a good electrical connection.
- R (Remote Turn-On): Tilslut til fjernbetjeningens udgang på din hovedenhed. Denne ledning tænder amptænd og sluk for højttaleren med dit stereoanlæg.
Lydindgangsforbindelser:
Choose either High Input or Low Input, but not both simultaneously.
- Høj input: If your head unit does not have RCA outputs, connect the speaker outputs of your head unit to the High Input connector using the provided harness.
- Lav indgang (RCA): Hvis din hovedenhed har RCA pre-outs, skal du tilslutte RCA-kabler fra hovedenheden til amplifier's Low Input jacks.
Højttalerforbindelser:
- Tilslut dine højttalere til amplifier's speaker terminals (L+, L-, R+, R-). Ensure correct polarity (+ to + and - to -).
- De amplifier supports a minimum speaker impedance of 4 ohms per channel.
Betjeningsvejledning
Indledende opstart:
- Når alle tilslutninger er foretaget og verificeret, skal køretøjets batteri tilsluttes igen.
- Tænd din hovedenhed. amplifier should power on, indicated by the "POWER" LED.
Justering af indstillinger:
- Niveaukontrol: Start with the Level control at its minimum setting. Play a familiar audio track at a moderate volume from your head unit. Slowly increase the amplifier's Level control until you hear distortion, then back it off slightly. This sets the input sensitivity.
- Filter Switch:
- FULD: For full-range speakers (e.g., coaxial speakers).
- LAV PAS: For subwoofers. This setting filters out high frequencies, allowing only low frequencies to pass through.
Opretholdelse
- Behold ampFjerneren er ren og fri for støv og snavs. Brug en blød, tør klud til rengøring.
- Sørg for tilstrækkelig luftgennemstrømning omkring ampfor at forhindre overophedning.
- Kontrollér regelmæssigt alle ledningsforbindelser for tæthed og korrosion.
Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen strøm / ingen lyd | Sprunget sikring | Check and replace the fuse on the power line. |
| Ingen strøm / ingen lyd | Løs strøm- eller jordforbindelse | Verify all power (B+, B-, R) and ground connections are secure. |
| Ingen strøm / ingen lyd | Fjernbetjeningsledning ikke tilsluttet eller defekt | Ensure the remote wire is connected to the head unit's remote output and is receiving 12V when the head unit is on. |
| Forvrænget lyd | Level control set too high | Reducer amplifier's Level control. |
| Forvrænget lyd | Speaker wires shorted or incorrect impedance | Check speaker wiring for shorts and ensure speakers meet the amplifier's impedance requirements (4 ohms minimum). |
| No Sound from one channel | Faulty RCA cable or speaker wire | Check RCA and speaker connections for the affected channel. |
| Amplifier overophedes | Utilstrækkelig ventilation | Flyt amplifier to a better-ventilated area or clear obstructions. |
| Amplifier overophedes | Højttalerimpedansen er for lav | Ensure speakers meet the minimum impedance requirement. |
