Oppsett og installasjon

Riktig installasjon er avgjørende for optimal ytelse og sikkerhet. Det anbefales å ha dette amplifier installert av en kvalifisert fagperson.

1. Montering av Amplivligere

Velg et monteringssted som er tørt, godt ventilert og beskyttet mot direkte sollys eller sterk varme. Sørg for tilstrekkelig plass rundt amplifier for air circulation. Use the provided mounting hardware to secure the ampløfteren fast.

2. Kablingstilkoblinger

Sørg for at kjøretøyets batteri er frakoblet før du foretar noen elektriske tilkoblinger.

• Strømtilkobling (+12V): Connect a suitable gauge power cable from the vehicle's positive battery terminal to the +12V terminal on the amplifier. An in-line fuse (not supplied) should be installed within 18 inches (45 cm) of the battery.
• Jordforbindelse (GND): Connect a short, heavy-gauge ground cable from the GND terminal on the amplifier to a clean, unpainted metal surface on the vehicle's chassis.
• Fjernstyrt påslåing (REM): Koble en fjernstyrt påkoblingsledning fra hovedenhetens fjernutgang til REM-terminalen på amplifier. If your head unit does not have a remote output, the amplifier features an auto-sense turn-on mode (DC offset or Audio Sense) which can be selected.
• Høyttalertilkoblinger: Koble høyttalerne til amplifier's speaker output terminals. Observe correct polarity (+ to + and - to -). The amplifier supports 4-channel stereo or 2-channel bridged configurations.
• Input Connections (RCA or High-Level): Koble hovedenhetens RCA-utganger til amplifier's RCA input jacks. If your head unit lacks RCA outputs, use the supplied high-level input adapters to connect to your head unit's speaker outputs.

Driftskontroller

The JBL CLUB-704 amplifier features various controls to fine-tune your audio experience. These controls are typically located under a removable panel for protection and a clean aesthetic.

• Input Level (HI/LO): Selects between high-level (speaker-level) or low-level (RCA) input signals.
• Forsterkningskontroll (MIN/MAX): Justerer inngangsfølsomheten til amplifier to match the output of your head unit. Start with minimum gain and slowly increase until desired volume is achieved without distortion.
• Crossover (X-OVER - HPF/LPF/FULL): Selects the type of filter for the output.
  • HPF (høypassfilter): Allows frequencies above the set point to pass through, ideal for full-range speakers.
  • LPF (lavpassfilter): Allows frequencies below the set point to pass through, ideal for subwoofers.
  • FULL: Allows all frequencies to pass through, bypassing the crossover.
• Frekvens (FREQ): Adjusts the cutoff frequency for the HPF or LPF, typically ranging from 32Hz to 320Hz.
• Bass Boost (0dB/12dB): Provides an adjustable bass boost at 45Hz to enhance low-frequency output.
• Fase (0°/180°): Adjusts the phase of the output signal, useful for optimizing bass response with subwoofers.
• Turn-On Mode (DC/REM): Selects how the ampløfteren slår seg på.
  • DC: Detects a DC offset on the high-level inputs to turn on the amplivligere.
  • REM: Uses a dedicated remote turn-on wire from the head unit.

Vedlikehold

To ensure long-lasting performance from your JBL CLUB-704 ampLifier, følg disse enkle vedlikeholdsretningslinjene:

• Rengjøring: Tørk av regelmessig amplifier's exterior with a soft, dry cloth to remove dust and dirt. Avoid using harsh chemicals or abrasive cleaners.
• Ventilasjon: Sørg for at amplifier's cooling fins are free from obstructions to allow proper heat dissipation.
• Tilkoblinger: Sjekk alle ledningsforbindelser med jevne mellomrom for å sikre at de er sikre og fri for korrosjon. Løse forbindelser kan føre til dårlig ytelse eller skade.
• Bytte sikring: If a fuse blows, replace it only with a fuse of the same type and rating (30A). Using an incorrect fuse can damage the ampeller forårsake brann.

Feilsøking

Hvis du opplever problemer med din amplifier, refer to the following common troubleshooting steps before contacting support:

• Ingen strøm: Check the power, ground, and remote turn-on connections. Verify the in-line fuse near the battery and the fuses on the amplifier. Ensure the vehicle's battery has sufficient charge.
• Ingen lyd: Check all RCA or high-level input connections. Verify speaker wiring for correct polarity and secure connections. Ensure the head unit is powered on and sending an audio signal. Adjust gain settings.
• Forvrengt lyd: Reduce the gain setting on the amplifier. Check for proper impedance matching with your speakers. Ensure speaker wires are not shorted.
• AmpOveroppheting av væskefilter: Sørg for at amplifier has adequate ventilation and is not covered. Check speaker impedance to ensure it is within the amplifier's rated limits.
• Protection Light On (PWR/PROT): If the protection light is illuminated, the amplifier has detected an issue (e.g., short circuit, overheating, low voltage). Disconnect power, check all wiring, and allow the unit to cool down before reconnecting.
