Persediaan dan Pemasangan
Proper installation is crucial for optimal performance and longevity of your marine amplifier. It is recommended that installation be performed by a qualified marine electronics technician.
Pertimbangan Pemasangan
- The amplifier is designed for surface mounting.
- Choose a location that is dry, well-ventilated, and protected from direct sunlight and excessive heat.
- Ensure adequate space around the amplifier for air circulation, especially around the heat sink.
- Avoid mounting near heat sources or in areas where it may be exposed to direct water spray.
Gambarajah Pendawaian (Konseptual)
Below is a conceptual overview of the wiring connections. Refer to the detailed wiring diagram in the full PDF user manual for precise instructions.
- Sambungan Kuasa: Sambungkan amplifier to a stable 12V DC power source (12.25V nominal, up to 16V max) with appropriate gauge wiring and an inline fuse.
- Sambungan Tanah: Ensure a solid ground connection to the boat's common ground point.
- Hidupkan Jauh: Connect to the remote output of your marine stereo head unit.
- Input RCA: Connect audio signal cables from your head unit's pre-outs to the amplifier's RCA inputs (CH1/2, CH3/4).
- Keluaran Pembesar suara: Connect your marine speakers to the amplifier's speaker terminals. Observe correct polarity and impedance (2 ohm stable).

Mengendalikan Amplebih hidup
Setelah dipasang, amplifier operates in conjunction with your marine stereo head unit. Adjustments can be made using the controls on the amppenguat itu sendiri.
Pelarasan Audio
- Kawalan Tahap: Adjusts the input sensitivity to match the output of your head unit. Start with the level control at minimum and slowly increase until desired volume is achieved without distortion.
- Crossover Filters (X-OVER SELECTOR):
- LP (Hantaran Rendah): Allows only low frequencies to pass through, typically used for subwoofers. Adjustable from 40Hz to 160Hz.
- HP (Pas Tinggi): Allows only high frequencies to pass through, typically used for full-range speakers. Adjustable from 40Hz to 600Hz.
- FLAT: Disables the crossover filter, allowing all frequencies to pass through.
- Peningkatan Bass: Provides an adjustable bass enhancement from 0dB to +18dB, centered around 45Hz. Use sparingly to avoid distortion.
- Penapis Subsonik: Filters out extremely low frequencies (20Hz to 55Hz) that are below the audible range or harmful to subwoofers, improving sound quality and protecting speakers.
Nota: Always make small adjustments and listen carefully to the audio output to prevent damage to speakers or the amplebih hidup.
Penyelenggaraan
The Fusion AM Series amplifier is designed for durability in the marine environment. Regular, simple maintenance can help ensure its long-term performance.
- Pembersihan: Lap bahagian luar secara berkala ampLiifier dengan lembut, damp kain. Elakkan menggunakan bahan kimia yang keras atau pembersih yang kasar.
- Sambungan: Annually inspect all wiring connections (power, ground, remote, RCA, speaker) to ensure they are secure and free from corrosion. Tighten any loose connections.
- Pengudaraan: Ensure that the area around the amplifier's heat sink remains clear of obstructions to allow for proper airflow and cooling.
- Perlindungan Alam Sekitar: While designed for marine use, minimizing exposure to direct saltwater spray and extreme temperatures will prolong the life of the unit.
Menyelesaikan masalah
If you experience issues with your Fusion AM Series amplifier, consult the following common troubleshooting steps before seeking professional assistance.
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Tiada kuasa/AmpPemanas Tidak Menghidupkan | Blown fuse; Loose power/ground connection; Faulty remote turn-on wire. | Check and replace fuse; Verify all power and ground connections are secure; Test remote wire for 12V signal. |
| Tiada Output Audio | Loose RCA cables; Incorrect input level setting; Speaker wires disconnected or shorted; Head unit issue. | Ensure RCA cables are firmly connected; Adjust input level; Check speaker wiring for shorts or disconnections; Test head unit functionality. |
| Bunyi Herot | Input level too high; Speaker impedance mismatch; Damaged speakers; Incorrect crossover settings. | Reduce input level; Verify speaker impedance (2 ohm stable); Inspect speakers for damage; Adjust crossover settings. |
| Amplifier Terlalu Panas | Insufficient ventilation; Overloaded speakers; Low impedance load. | Ensure clear airflow around heat sink; Check speaker impedance; Reduce volume or number of speakers if overloaded. |
If the problem persists after attempting these solutions, contact Fusion customer support or a certified technician.
