4. Opsætning og installation
4.1 Monteringssted
Vælg et tørt, godt ventileret og sikkert monteringssted. Undgå at montere amplifier directly on carpet or in enclosed spaces that restrict airflow. Common locations include under seats, in the trunk, or behind rear seats. Ensure the ampLifteren er sikkert fastgjort for at forhindre bevægelse under køretøjets kørsel.
4.2 Strømledninger
- Effekt (B+): Connect a suitable gauge power wire (e.g., 4-gauge) directly from the vehicle's positive battery terminal to the amplifier's B+ terminal. Install an in-line fuse holder within 18 inches (45 cm) of the battery.
- Jord (GND): Connect a suitable gauge ground wire (e.g., 4-gauge) from the amplifier's GND terminal to a clean, unpainted metal surface on the vehicle chassis. Ensure a solid electrical connection. The ground wire should be as short as possible, ideally less than 3 feet (1 meter).
- Fjernbetjening (REM): Connect a remote turn-on wire (e.g., 18-gauge) from your head unit's remote output to the ampforsyningens REM-terminal. Denne ledning signalerer amplifier til at tænde og slukke med hovedenheden.
4.3 Signalindgang (RCA)
Connect RCA cables from your head unit's preamp udgange til de tilsvarende RCA-indgangsstik på amplifier. The PA D5000.5 features inputs for Front, Rear, and Subwoofer channels. If your head unit has fewer RCA outputs, you may use the amplifier's input source switch (SUB/INT) to route signals internally.
4.4 Højttalerledninger
Tilslut dine højttalere til amplifier's speaker output terminals. Ensure correct polarity (+ to + and - to -) for all speakers. The amplifier supports 4 channels for full-range speakers and a dedicated subwoofer channel. Refer to your speaker's impedance rating and the amplifiers specifikationer for at sikre kompatibilitet.
- Kanaler 1-4: Connect your front and rear full-range speakers.
- Subwoofer-kanal: Connect your subwoofer. The 5th channel is 1-ohm stable for flexible subwoofer configurations.
5. Betjeningsvejledning
The PA D5000.5 features several adjustable controls to fine-tune your audio system. These controls are located on the amplifier's control panel (refer to Figure 2).
5.1 Input Selection (SUB/INT)
- SUB: Select this if you are providing a dedicated RCA input signal for the subwoofer channel.
- INT (Internal): Select this if you want the subwoofer channel to receive its signal internally from the front or rear channels, typically when a dedicated subwoofer RCA output is not available from the head unit.
5.2 Level Controls (Gain)
Adjust the LEVEL controls for Front, Rear, and Subwoofer channels to match the output voltage of your head unit. Start with the gain set to minimum and slowly increase it until the desired volume is achieved without distortion. Using an oscilloscope for precise gain setting is recommended to prevent clipping.
5.3 Delefiltreindstillinger
De amplifier includes adjustable crossover filters to optimize sound distribution to your speakers.
- HPF (højpasfilter): Allows frequencies above the set point to pass through. Use for full-range speakers to prevent them from playing low bass frequencies. Adjustable from 40Hz to 400Hz.
- LPF (lavpasfilter): Allows frequencies below the set point to pass through. Use for subwoofers to ensure they only play bass frequencies. Adjustable from 40Hz to 220Hz.
- BPF (Band-Pass Filter): Allows a specific range of frequencies to pass through. This can be used for mid-range speakers or specific system designs.
- SONIC: A bass boost control for the subwoofer channel, adjustable from 0 to +12dB at 45Hz. Use sparingly to avoid distortion.
5.4 kanaltilstand
- ST (Stereo): Standard stereo operation for the front and rear channels.
- RR (Rear): This setting may be used for specific bridging or input configurations, consult a professional installer if unsure.
5.5 Remote Level Control
Connect the included remote bass level control knob to the dedicated port. This allows for convenient adjustment of the subwoofer output level from the driver's seat.

| Amplifier turns on but no sound | No input signal; Incorrect gain settings; Loose speaker wires; Head unit issue. | Check RCA cable connections. Adjust gain levels. Verify speaker wire connections and polarity. Test head unit functionality. |
| Forvrænget lyd | Forstærkningen er indstillet for højt; Forkerte delefiltreindstillinger; Uoverensstemmelse mellem højttalerimpedansen; Beskadigede højttalere. | Reduce gain level. Adjust HPF/LPF settings. Verify speaker impedance is within amplifier's rated range. Inspect speakers for damage. |
| Amplifier goes into protection mode (Protection LED on) | Overheating; Short circuit in speaker wiring; Speaker impedance too low; DC offset. | Ensure adequate ventilation. Check all speaker wires for shorts to ground or each other. Verify speaker impedance. Allow ampvarmebeholder for at køle ned. |
| Hissing or background noise | Poor grounding; RCA cable interference; Gain set too high. | Ensure a solid, clean ground connection. Route RCA cables away from power wires. Reduce gain levels. |
| Turn-off pop | Head unit remote turn-off delay; Ground loop. | Ensure head unit turns off before amplifier. Check ground connections. Consider a ground loop isolator if necessary. |
