Настройка и установка
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.
Вопросы монтажа
- The amplifier is designed for surface mounting.
- Выберите сухое, хорошо проветриваемое место, защищенное от прямых солнечных лучей и чрезмерной жары.
- Обеспечьте достаточное пространство вокруг 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.
Схема электропроводки (концептуальная)
Below is a conceptual overview of the wiring connections. Refer to the detailed wiring diagram in the full PDF user manual for precise instructions.
- Подключение питания: Подключите amplifier to a stable 12V DC power source (12.25V nominal, up to 16V max) with appropriate gauge wiring and an inline fuse.
- Заземление: Ensure a solid ground connection to the boat's common ground point.
- Дистанционное включение: Connect to the remote output of your marine stereo head unit.
- Входы RCA: Connect audio signal cables from your head unit's pre-outs to the amplifier's RCA inputs (CH1/2, CH3/4).
- Выходы на динамики: Подключите морские колонки к amplifier's speaker terminals. Observe correct polarity and impedance (2 ohm stable).

Эксплуатация Ampпожизненнее
После установки amplifier operates in conjunction with your marine stereo head unit. Adjustments can be made using the controls on the ampсам лифер.
Настройки звука
- Контроль уровня: 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):
- НЧ (фильтр нижних частот): Allows only low frequencies to pass through, typically used for subwoofers. Adjustable from 40Hz to 160Hz.
- HP (Высокочастотный фильтр): Allows only high frequencies to pass through, typically used for full-range speakers. Adjustable from 40Hz to 600Hz.
- ПЛОСКИЙ: Disables the crossover filter, allowing all frequencies to pass through.
- Усиление басов: Provides an adjustable bass enhancement from 0dB to +18dB, centered around 45Hz. Use sparingly to avoid distortion.
- Дозвуковой фильтр: Filters out extremely low frequencies (20Hz to 55Hz) that are below the audible range or harmful to subwoofers, improving sound quality and protecting speakers.
Примечание: Always make small adjustments and listen carefully to the audio output to prevent damage to speakers or the ampпожизненнее.
Обслуживание
The Fusion AM Series amplifier is designed for durability in the marine environment. Regular, simple maintenance can help ensure its long-term performance.
- Уборка: Периодически протирайте внешнюю поверхность amplifier с мягким, дamp ткань. Избегайте использования агрессивных химикатов или абразивных чистящих средств.
- Соединения: Annually inspect all wiring connections (power, ground, remote, RCA, speaker) to ensure they are secure and free from corrosion. Tighten any loose connections.
- Вентиляция: Убедитесь, что территория вокруг amplifier's heat sink remains clear of obstructions to allow for proper airflow and cooling.
- Охрана окружающей среды: While designed for marine use, minimizing exposure to direct saltwater spray and extreme temperatures will prolong the life of the unit.
Поиск неисправностей
If you experience issues with your Fusion AM Series amplifier, consult the following common troubleshooting steps before seeking professional assistance.
| Проблема | Возможная причина | Решение |
|---|---|---|
| Нет питания/Ampлайфер не включается | 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. |
| Нет аудиовыхода | 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. |
| Искаженный звук | 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 Перегрев | 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.
