5. Persediaan dan Pemasangan
Pemasangan yang betul adalah penting untuk prestasi dan keselamatan yang optimum. Ikuti langkah-langkah ini dengan teliti.
5.1 Penempatan
The ISUBACTIVE subwoofer is designed for compact integration, typically under a car seat. Ensure the chosen location allows for:
- Adequate air circulation around the unit to prevent overheating.
- Secure mounting to prevent movement during vehicle operation.
- Easy access to controls for initial setup and adjustments.
5.2 Sambungan Pendawaian
Sebelum membuat sebarang sambungan, cabut terminal negatif bateri kenderaan.
- Sambungan Kuasa (+12V): Connect a suitable gauge power cable from the vehicle's positive battery terminal (with an inline fuse located within 18 inches of the battery) to the +12V terminal on the subwoofer.
- Sambungan Tanah (GND): Connect a suitable gauge ground cable from the GND terminal on the subwoofer to a clean, unpainted metal surface on the vehicle chassis. Ensure a good electrical contact.
- Penghidupan Jauh (REM): Connect a remote turn-on wire from your car radio's remote output to the REM terminal on the subwoofer. If using High-Level inputs with the AUTO TURN ON feature, this connection may not be necessary.
- Input Isyarat:
- Input Aras Tinggi (Aras Pembesar Suara): Use the supplied Plug & Play ISO cable to connect to your car radio's speaker outputs. Ensure correct polarity. Set the AUTO TURN ON switch to 'ON' if you want the subwoofer to power on automatically with the radio.
- Input Aras Rendah (RCA): If your car radio has RCA pre-outs, connect RCA cables from the radio to the LOW LEVEL (RCA) inputs on the subwoofer.
- Kawalan Jauh (Pilihan): If using a wired remote control, connect it to the REMOTE CONTROL port.
- Speaker Outputs (Optional): If your model variant includes speaker outputs, connect your additional speakers here, observing polarity.
Setelah semua sambungan dibuat, sambungkan semula terminal bateri negatif kenderaan.
6. Arahan Operasi
Selepas pemasangan, ikuti langkah-langkah ini untuk mengkonfigurasi subwoofer anda bagi mendapatkan bunyi yang optimum.
6.1 Pelarasan Kuasa dan Gain Awal
- Turn on your car radio. The subwoofer's POWER STATUS LED should illuminate green. If it's red or off, refer to the Troubleshooting section.
- Set the GAIN control on the subwoofer to its minimum position.
- Play a piece of music with a good bass presence through your car radio.
- Slowly increase the volume on your car radio until it reaches about 75% of its maximum level, or just before distortion becomes audible from your main speakers.
- Gradually increase the GAIN control on the subwoofer until the bass blends smoothly with your main speakers without overpowering them or sounding distorted.
6.2 Melaraskan Kawalan Audio
- LOW-PASS Filter (50Hz - 180Hz): This control determines the highest frequency the subwoofer will reproduce. Start by setting it around 80-100Hz. Adjust it to blend the subwoofer's output with your main speakers. If your main speakers are small, you might set it higher; if they are large, you might set it lower.
- SUBSONIC Filter (20Hz - 50Hz): This high-pass filter for the subwoofer removes very low, inaudible frequencies. Setting it around 25-30Hz can improve efficiency and prevent damage from extreme low-frequency content.
- BASS-BOOST (0 - +18dB): Use this control sparingly to add a slight emphasis to the bass if desired. Excessive boost can lead to distortion.
- PHASE (0° - 180°): This switch helps integrate the subwoofer's output with your main speakers. Listen to music with strong bass and switch between 0° and 180°. Choose the setting that provides the most impactful and cohesive bass response.
7. Penyelenggaraan
The Focal ISUBACTIVE subwoofer requires minimal maintenance.
- Pembersihan: Gunakan kain lembut dan kering untuk membersihkan bahagian luar unit. Jangan gunakan bahan kimia yang keras atau pembersih yang kasar.
- Pemeriksaan: Periksa semua sambungan pendawaian secara berkala untuk memastikan ia selamat dan bebas daripada kakisan.
- Pengudaraan: Ensure that the area around the subwoofer remains clear of obstructions to maintain proper airflow.
