5. Persediaan dan Pemasangan
Pemasangan yang betul adalah penting untuk prestasi dan jangka hayat peranti anda amplampu. Jika anda tidak pasti tentang sebarang langkah, rujuk pemasang profesional.
5.1 Memasang Amplebih hidup
- Choose a mounting location that is dry, well-ventilated, and protected from direct sunlight and excessive heat.
- Pastikan ruang yang mencukupi di sekeliling amplifier for proper airflow, especially around the heatsink fins.
- Selamatkan amplifier firmly to a solid surface using appropriate screws and mounting hardware. Avoid mounting on carpet or other materials that could obstruct cooling.
5.2 Sambungan Pendawaian
Use high-quality wiring for all connections. 4-gauge power and ground leads are recommended for the FPS 1500.
- Power Wire (+12V): Run a 4-gauge power wire directly from the positive terminal of the vehicle's battery to the +12V terminal on the amplifier. Install an appropriate fuse holder (not supplied) within 18 inches (45 cm) of the battery.
- Wayar Tanah (GND): Connect a 4-gauge ground wire from the GND terminal on the amppenyala pada permukaan logam yang bersih dan tidak dicat pada casis kenderaan. Pastikan sambungan yang kukuh dan berrintangan rendah.
- Wayar Penghidup Jauh (REM): Connect a remote turn-on wire (typically 18-gauge) from the remote output of your head unit to the REM terminal on the amppengalir. Wayar ini memusingkan amphidupkan dan matikan lampu dengan unit kepala anda.
- RCA Input Cables: Connect high-quality RCA cables from the subwoofer pre-out of your head unit to the RCA input jacks on the amplebih hidup.
- Wayar Pembesar suara: Connect your subwoofer(s) to the speaker output terminals on the amplifier. Ensure correct polarity (+ to + and - to -). Refer to your subwoofer's specifications for impedance matching. The FPS 1500 is stable down to 1 ohm.
6. Arahan Operasi
Once all connections are made and verified, you can power on your system and adjust the amptetapan penguat.
6.1 Kuasa Permulaan
- Sambung semula terminal bateri negatif kenderaan.
- Hidupkan unit kepala anda. amplifier should power on, indicated by the power LED.
- Mulakan dengan ampKawalan gandaan lifier ditetapkan kepada minimum.
6.2 Melaraskan Tetapan
- Kawalan Keuntungan: Play a familiar piece of music with a strong bass presence. Slowly increase the gain control on the amplifier until you hear distortion, then back it off slightly. This matches the amplifier's input sensitivity to your head unit's output.
- Penapis Laluan Rendah: Set the low-pass filter frequency to blend smoothly with your main speakers. A common starting point is 80-100 Hz, but this may vary depending on your system.
- Penapis Subsonik: If your subwoofer is ported or you are experiencing excessive cone excursion at very low frequencies, engage the subsonic filter (20 Hz). This protects the subwoofer from playing frequencies below its safe operating range.
- Peningkatan Bass: Use the bass boost sparingly. Excessive bass boost can lead to distortion and potential damage. Adjust to your preference, ensuring the sound remains clean.
- Suis Fasa: Experiment with the 0 and 180-degree phase settings. Choose the setting that provides the most impactful and coherent bass response from your listening position.
The FPS 1500 features Dynamic Soft Clipping, which helps protect your speakers from distortion by gently limiting the output when the amplifier is driven beyond its clean power capabilities.
