Tehničke specifikacije

Napomena: All specifications are subject to change without notice. Performance may vary based on installation and environmental factors.

Postavljanje i instalacija

Proper installation is crucial for the performance and longevity of your subwoofer. If you are unsure about any steps, it is recommended to seek professional installation.

1. Sigurnosne mjere

• Disconnect the vehicle's battery before starting any electrical work to prevent electrical shorts or damage.
• Nosite odgovarajuću zaštitnu opremu, uključujući zaštitu za oči, tokom instalacije.
• Ensure all wiring is correctly gauged for the power levels and properly fused to protect the system.

2. Odabir i konstrukcija kućišta

The DD Audio 1112-D4 is designed to perform optimally in specific enclosure volumes:

• Zapremina zatvorenog kućišta: 0.8 - 1.5 cubic feet
• Zapremina kućišta s portovima: 0.8 - 1.75 cubic feet

Ensure the enclosure is robust, airtight (for sealed designs), and properly braced to prevent rattles and vibrations that can degrade sound quality.

3. Wiring the Dual 4-Ohm Voice Coils

The 1112-D4 features dual 4-ohm voice coils, offering flexibility in wiring configurations to match your amplifier's impedance requirements. Always verify your amplifier's stable impedance range before wiring.

• Paralelno ožičenje (2 oma): Spojite pozitivne terminale obje zvučne zavojnice zajedno i negativne terminale obje zvučne zavojnice zajedno. Zatim spojite ove kombinirane pozitivne i negativne terminale na vaš amplifier. This configuration presents a 2-ohm load to the amplifier.
• Serijsko ožičenje (8 oma): Connect the positive terminal of one voice coil to the negative terminal of the other voice coil. Then connect the remaining positive and negative terminals to your amplifier. This configuration presents an 8-ohm load to the amplifier.

Warning: Incorrect impedance matching can damage your amplifier or subwoofer. Consult your amppriručnik proizvođača za kompatibilne impedanse opterećenja.

4. Montiranje subwoofera

• Ensure the mounting surface within the enclosure is flat and secure.
• Use appropriate screws and ensure a tight, airtight seal between the subwoofer frame and the enclosure to prevent air leaks.
• The mounting diameter required is 10.937 inches, and the mounting depth is 5.8 inches. Verify these dimensions against your enclosure design.

Operativne smjernice

1. Rukovanje snagom

The DD Audio 1112-D4 has a recommended RMS power range of 200-400 watts and a peak power handling of 800 watts. It is crucial to match your amplifier's output to these specifications. Underpowering can be as damaging as overpowering, as it can lead to amplifier clipping and excessive distortion, which can damage the subwoofer.

2. AmpLifier Settings

• Postavka pojačanja: Postavite amppravilno podesite pojačanje lifiera kako biste uskladili izlaznu jačinu zvukatage of your head unit. The gain control is not a volume knob; it should be set to prevent clipping and distortion at maximum desired listening levels.
• Niskopropusni filter (LPF): Podesite LPF na svom amplifier or head unit to filter out frequencies above the subwoofer's intended range, typically between 60Hz and 100Hz. This ensures the subwoofer only reproduces bass frequencies.
• Subsonični filter (HPF): Ako je vaš amplifier has a subsonic filter, set it to protect the subwoofer from playing frequencies below its resonant frequency (Fs: 35Hz), usually around 25-30Hz. This prevents wasted power and potential damage from extreme low-frequency excursions.

3. Period uhodavanja

Allow a break-in period of approximately 10-20 hours of moderate listening before operating the subwoofer at high volumes. This allows the suspension components (surround and spider) to loosen up and reach their optimal performance characteristics, improving sound quality and longevity.

Održavanje

• čišćenje: Use a soft, dry cloth to gently clean the subwoofer cone and surround. Avoid using harsh chemicals, solvents, or excessive moisture, which can damage the materials.
• inspekcija: Periodically inspect all wiring connections for tightness and signs of corrosion. Check the subwoofer surround and cone for any signs of physical damage, tears, or deterioration.
• Faktori okoline: Protect the subwoofer from extreme temperatures, direct sunlight, and moisture. These conditions can degrade materials and affect performance over time.

Rješavanje problema

If you experience issues with your subwoofer, consult the following common problems and solutions:

• Nema zvuka:
  • Check all wiring connections (power, ground, remote, RCA, speaker wires) for proper connection and continuity.
  • Potvrdite amplifier is powered on (check its power indicator light).
  • Provjerite osigurače na amplifier and the main power wire.
  • Ensure the head unit is sending an audio signal to the amplifier.
• izobličeni zvuk:
  • Smanji amppojačanje lifiera kako bi se spriječilo klipsanje.
  • Check for proper LPF and subsonic filter settings.
  • Ensure the subwoofer is not over-excursion (playing too loud for its capabilities).
  • Pregledajte membranu i okvir subwoofera na fizička oštećenja.
• Slab bas:
  • Verify amplifier gain and LPF settings are optimized.
  • Check for correct wiring impedance matching between the subwoofer and amplifier.
  • Osigurajte da je kućište pravilno zatvoreno (ako je primjenjivo) i da nema curenja zraka.
  • Confirm the phase setting on the amplifier or head unit is correct.
• Pregrijavanje subwoofera:
  • Osigurajte odgovarajuću ventilaciju oko amplifier.
  • Check for correct impedance matching; an impedance too low can cause overheating.
  • Avoid prolonged operation at maximum volume, especially during the break-in period.

If these steps do not resolve the issue, contact DD Audio customer support or a qualified car audio technician for further assistance.
