5. Installation

Korrekt installation er afgørende for din ydeevne og levetid amplifier. Always disconnect the vehicle's negative battery terminal before beginning installation.

5.1 Montering af Amplivligere

Choose a mounting location that provides adequate ventilation and is protected from moisture. Common locations include the trunk, under a seat, or behind a panel. Ensure the mounting surface is solid and secure.

Placer amplifier in the desired location and mark the mounting holes.
Drill pilot holes if necessary, ensuring not to damage any vehicle components beneath the surface.

5.2 Ledningsforbindelser

Der henvises til amplifier's terminal labels for correct connections. Use high-quality wiring of appropriate gauge.

Effekt (B+): Connect a fused power cable directly from the positive terminal of the vehicle's battery to the amplifier's B+ terminal. The fuse holder should be installed within 18 inches (45 cm) of the battery.
Jord (GND): Tilslut et jordkabel med samme tykkelse som strømkablet fra ampForbind GND-terminalen på laderen til en ren, umalet metaloverflade på køretøjets chassis. Sørg for en solid forbindelse med lav modstand.
Fjernbetjening (REM): Tilslut en fjernbetjeningsledning fra din hovedenheds fjernbetjeningsudgang til ampforsyningens REM-terminal. Denne ledning tænder amptænd og sluk for støjrelæet med din hovedenhed.
RCA-indgange: Connect RCA cables from your head unit's subwoofer or full-range pre-outs to the ampliferens RCA-indgangsstik.
Højttalerudgange: Tilslut din(e) subwoofer(e) til amplifier's speaker output terminals. Ensure the total impedance of the connected speakers is within the amplifier's specified operating range (2 ohms minimum for this mono amplivligere).
RCA Line Outputs: If daisy-chaining multiple amplifiers, connect RCA cables from these outputs to the inputs of the next amplivligere.

6. Betjening

Once all connections are made and verified, reconnect the vehicle's negative battery terminal. Turn on your head unit. The amplifier should power on, indicated by an illuminated power LED (if present).

Begynd med amplifier's gain control set to minimum and the head unit's volume low. Gradually increase the head unit's volume and then slowly adjust the amplifier's gain control until the desired output level is achieved without distortion.

7. Justeringer

The QB2000D offers several adjustable controls to fine-tune your audio system:

Input Level (Gain): Passer til amptransformerens indgangsfølsomhed i forhold til udgangsvolumentage of your head unit. Adjust carefully to prevent distortion.
Low-Pass Crossover (LPF): Filters out frequencies above the set point, allowing only lower frequencies to pass to the subwoofer. This is continuously variable (e.g., 50Hz - 250Hz).
Subsonisk filter: Filters out extremely low, inaudible frequencies that can waste amplifier power and potentially damage subwoofers. This is continuously variable (15-55Hz).
Bass Boost: Provides an adjustable boost at 45Hz to enhance bass impact. Use sparingly to avoid distortion and speaker damage.

Adjust these controls incrementally and listen for improvements in sound quality. Over-adjustment can lead to distortion or damage.

8. Vedligeholdelse

The Quantum QB2000D ampLifier kræver minimal vedligeholdelse. Følg disse retningslinjer for at sikre dens levetid:

Hold rent: Tør regelmæssigt af ampRengør ydersiden af apparatet med en blød, tør klud for at fjerne støv og snavs. Brug ikke skrappe kemikalier eller slibende rengøringsmidler.
Sørg for ventilation: Regularly check that the heat sink fins are clear of obstructions and dust to maintain proper cooling.
Tjek forbindelser: Occasionally inspect all wiring connections for tightness and corrosion. Loose or corroded connections can degrade performance and cause overheating.
Udskiftning af sikring: If a fuse blows, replace it only with a fuse of the exact same type and rating (ATC 3 x 30 amp). Using an incorrect fuse can lead to damage or fire.
