مخطط الأسلاك (مفهومي)
Below is a conceptual overview of the wiring connections. Refer to the detailed wiring diagram in the full PDF user manual for precise instructions.
- توصيل الطاقة: قم بتوصيل amplifier to a stable 12V DC power source (12.25V nominal, up to 16V max) with appropriate gauge wiring and an inline fuse.
- اتصال الأرض: Ensure a solid ground connection to the boat's common ground point.
- تشغيل عن بعد: Connect to the remote output of your marine stereo head unit.
- مدخلات RCA: Connect audio signal cables from your head unit's pre-outs to the amplifier's RCA inputs (CH1/2, CH3/4).
- مخرجات مكبر الصوت: Connect your marine speakers to the amplifier's speaker terminals. Observe correct polarity and impedance (2 ohm stable).

تشغيل Ampالقمامة
بمجرد تثبيت ، و amplifier operates in conjunction with your marine stereo head unit. Adjustments can be made using the controls on the ampالمُحَمِّل نفسه.
تعديلات الصوت
- التحكم في المستوى: 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 (مرشح الترددات المنخفضة): Allows only low frequencies to pass through, typically used for subwoofers. Adjustable from 40Hz to 160Hz.
- HP (تمرير عالي): Allows only high frequencies to pass through, typically used for full-range speakers. Adjustable from 40Hz to 600Hz.
- مستوي: Disables the crossover filter, allowing all frequencies to pass through.
- تعزيز الجهير: Provides an adjustable bass enhancement from 0dB to +18dB, centered around 45Hz. Use sparingly to avoid distortion.
- مرشح دون سرعة الصوت: Filters out extremely low frequencies (20Hz to 55Hz) that are below the audible range or harmful to subwoofers, improving sound quality and protecting speakers.
ملحوظة: Always make small adjustments and listen carefully to the audio output to prevent damage to speakers or the ampمكبر.
صيانة
The Fusion AM Series amplifier is designed for durability in the marine environment. Regular, simple maintenance can help ensure its long-term performance.
- تنظيف: امسح الجزء الخارجي من الجهاز بشكل دوري amplifier مع لينة، دamp قماش. تجنب استخدام المواد الكيميائية القاسية أو المنظفات الكاشطة.
- الاتصالات: Annually inspect all wiring connections (power, ground, remote, RCA, speaker) to ensure they are secure and free from corrosion. Tighten any loose connections.
- تهوية: تأكد من أن المنطقة المحيطة بـ amplifier's heat sink remains clear of obstructions to allow for proper airflow and cooling.
- حماية البيئة: While designed for marine use, minimizing exposure to direct saltwater spray and extreme temperatures will prolong the life of the unit.
استكشاف الأخطاء وإصلاحها
If you experience issues with your Fusion AM Series amplifier, consult the following common troubleshooting steps before seeking professional assistance.
| مشكلة | السبب المحتمل | حل |
|---|---|---|
| لا حول/Ampالمضخم لا يعمل | 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. |
| لا يوجد إخراج صوتي | 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. |
| صوت مشوه | 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. |
| Ampارتفاع درجة حرارة المكيف | Insufficient ventilation; Overloaded speakers; Low impedance load. | Ensure clear airflow around heat sink; Check speaker impedance; Reduce volume or number of speakers if overloaded. |
