4.2 Sambungan Pendawaian

Proper wiring is crucial for performance and safety. Refer to the specifications for recommended wire gauges.

• Sambungan Kuasa: Connect the main power cable (2 x 0 AWG recommended) from the vehicle battery (with an appropriate inline fuse) to the amplifier's +12V terminals.
• Sambungan Tanah: Connect the ground cable (2 x 0 AWG recommended) from the amplifier's GND terminals to a solid, clean chassis ground point. Ensure a good metal-to-metal contact.
• Hidupkan Jauh: Connect the remote turn-on wire from your head unit or signal processor to the ampTerminal REM liifier. Wayar ini memberi isyarat kepada amplampu untuk menghidupkan dan mematikan sistem audio anda.
• RCA Audio Input: Connect the RCA audio input cables from your head unit or signal processor to the amplifier's RCA input jacks (L/R).
• Output pembesar suara: Connect your subwoofer(s) to the speaker output terminals using 10 AWG speaker wire, observing correct polarity.
• ZVL Input: The amplifier includes a ZVL Linking Module Input for advanced system configurations, allowing for linking multiple amppenyelamat.

5. Mengendalikan Amplebih hidup

5.1 Pelarasan Kuasa dan Gain Awal

After all connections are made and verified, turn on your audio system. Start with the amplifier's GAIN control at its minimum setting. Gradually increase the GAIN until the desired volume and sound quality are achieved without audible distortion. The remote control's clipping indicator is a valuable tool to prevent signal clipping, which can damage speakers.

5.2 Filter Adjustments

• Penapis SUBSONIK: This control adjusts the low-frequency cut-off (20 - 250Hz). Use it to filter out frequencies below the audible range or below the resonant frequency of your subwoofer enclosure, protecting your subwoofers from over-excursion.
• LOW-PASS Filter (LPF): This control adjusts the high-frequency cut-off (50 - 500Hz). Use it to ensure that only low frequencies are sent to your subwoofer(s), preventing them from playing mid-range or high-range sounds.

5.3 Alat Kawalan Jauh

The included remote control features an LCD voltage display and a clipping indicator. Use this to monitor your system's voltage and to visually identify when the audio signal is clipping. Adjust the gain or source volume to eliminate clipping, ensuring clean audio output and protecting your equipment.

6. Penyelenggaraan

• Simpan ampPastikan penghawa dingin bersih dan bebas daripada habuk dan serpihan. Gunakan kain lembut dan kering untuk membersihkan.
• Ensure ventilation fins are not blocked to maintain proper cooling and prevent overheating.
• Periodically check all wiring connections for tightness and corrosion. Loose or corroded connections can lead to poor performance or damage.

7. Penyelesaian masalah

• Tiada Kuasa: Check power, ground, and remote connections. Verify the inline fuse is intact. Ensure the vehicle battery has sufficient charge.
• Tiada Bunyi: Check RCA input connections. Verify speaker wiring polarity and connections. Ensure the head unit is powered on and outputting a signal.
• Bunyi Herot: Reduce the gain setting. Check for clipping using the remote indicator. Verify speaker impedance matches amplifier capabilities. Check for damaged speakers or wiring.
• AmpPemanasan berlebihan: Pastikan pengudaraan yang mencukupi di sekeliling amplifier. Check speaker impedance to ensure it is within the amplifier's rated range. Reduce prolonged high-volume operation.
