Wiring Diagram (Conceptual)
Below is a conceptual overview of the wiring connections. Refer to the detailed wiring diagram in the full PDF user manual for precise instructions.
- Enerji bağlantısı: birləşdirin amplifier to a stable 12V DC power source (12.25V nominal, up to 16V max) with appropriate gauge wiring and an inline fuse.
- Torpaq bağlantısı: Ensure a solid ground connection to the boat's common ground point.
- Uzaqdan yandırma: Connect to the remote output of your marine stereo head unit.
- RCA Girişləri: Connect audio signal cables from your head unit's pre-outs to the amplifier's RCA inputs (CH1/2, CH3/4).
- Dinamik Çıxışları: Connect your marine speakers to the amplifier's speaker terminals. Observe correct polarity and impedance (2 ohm stable).

Əməliyyat Ampömürlük
Quraşdırıldıqdan sonra amplifier operates in conjunction with your marine stereo head unit. Adjustments can be made using the controls on the ampqaldırıcı özü.
Audio Tənzimləmələr
- Səviyyəyə nəzarət: 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 (Aşağı Keçid): Allows only low frequencies to pass through, typically used for subwoofers. Adjustable from 40Hz to 160Hz.
- HP (Yüksək Keçid): Allows only high frequencies to pass through, typically used for full-range speakers. Adjustable from 40Hz to 600Hz.
- DƏMİŞ: Disables the crossover filter, allowing all frequencies to pass through.
- Bas Boost: Provides an adjustable bass enhancement from 0dB to +18dB, centered around 45Hz. Use sparingly to avoid distortion.
- Subsonik Filtr: Filters out extremely low frequencies (20Hz to 55Hz) that are below the audible range or harmful to subwoofers, improving sound quality and protecting speakers.
Qeyd: Always make small adjustments and listen carefully to the audio output to prevent damage to speakers or the ampömürlük.
Baxım
