4.1 Karatteristiċi tal-Panew tal-Kontroll

• IPROTEĠJA LED: Jdawwal meta l- ampL-illuminatur jinsab fil-modalità ta' protezzjoni minħabba sħana żejda, short circuit, jew vultaġġ baxxtage.
• LED POWER: Jdawwal meta l- ampIl-lifer huwa mixgħul u qed jaħdem normalment.
• REMOT: Input for the optional remote bass control knob.
• FAŻI (0°/180°): Switch to adjust the phase of the subwoofer output relative to the main speakers.
• LOW PASS (25Hz-250Hz): Variable control for the low-pass filter, allowing only frequencies below the set point to pass to the subwoofer.
• SUB SONIC (15Hz-55Hz): Variable control for the subsonic filter, which removes extremely low frequencies that are inaudible and can damage subwoofers.
• BASS BOOST (0dB-12dB): Variable control to boost bass frequencies at a specific point (e.g., 45Hz).
• LEVEL (Min/Max): Gain control to match the output of your head unit to the amplifier's input sensitivity.
• INPUT (RCA): RCA inputs for connecting the audio signal from your head unit.
• MASTER OUT (RCA): RCA output for daisy-chaining multiple ampliifikaturi.

4.2 Power and Speaker Terminals

• + 12V: Main power input from the vehicle's battery.
• REM: Remote turn-on input from the head unit.
• GND: Ground connection to the vehicle's chassis.
• ĦRUĠ TAL-ISPEKKER: Terminali għall-konnessjoni tas-subwoofer(s) tiegħek.

5. Setup u Installazzjoni

Installazzjoni xierqa hija kruċjali għal prestazzjoni u sigurtà ottimali.

5.1 Immuntar tal- Ampaktar ħaj

• Choose a mounting location that is dry, well-ventilated, and protected from direct sunlight or excessive heat.
• Kun żgur li hemm biżżejjed spazju madwar amplifier għaċ-ċirkolazzjoni tal-arja.
• Use the provided mounting hardware to securely fasten the amplifier to a solid surface.

5.2 Konnessjonijiet tal-Wiring

TWISSIJA: Disconnect the vehicle's battery negative terminal before making any power connections.

1. Konnessjoni mal-art (GND): Connect a heavy-gauge wire (e.g., 4 AWG or larger for 4000W max) from the amplifier's GND terminal directly to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid, low-resistance connection.
2. Konnessjoni tal-Enerġija (+12V): Qabbad wajer ta' daqs tqil (eż., 4 AWG jew akbar) mill- amplifier's +12V terminal directly to the positive terminal of the vehicle's battery. Install an appropriate fuse holder (e.g., 150A-200A ANL fuse) within 18 inches (45 cm) of the battery.
3. Remote Turn-On Connection (REM): Qabbad wajer ta' daqs iżgħar (eż., 18 AWG) mill- ampIt-terminal REM tal-lifer mal-output tal-mixgħul remot tal-unità ewlenija tiegħek. Dan il-wajer jagħti sinjal lill- amplifer biex tixgħel u titfi bl-istereo tiegħek.
4. RCA Input Connection: Connect RCA cables from the subwoofer output (or full-range output if using the amplifier's crossover) of your head unit to the INPUT RCA jacks on the ampaktar ħaj.
5. Konnessjoni tal-Output tal-Ispeaker: Connect your subwoofer(s) to the SPEAKER OUTPUT terminals. This amplifier is 1-ohm stable, allowing for flexible wiring configurations for single or multiple subwoofers. Ensure the total impedance of your subwoofer(s) is 1 ohm or higher. Refer to your subwoofer's manual for impedance information.

After all connections are made, reconnect the vehicle's battery negative terminal.

6. It-tħaddim tal- Ampaktar ħaj

6.1 Initial Power-Up and Gain Setting

1. Dawwar il- amplifier's LEVEL control to its minimum (Min) setting.
2. Turn on your head unit and set its volume to about 75% of maximum.
3. Żid bil-mod il- amplifier's LEVEL control until you hear distortion, then back it off slightly until the sound is clear. This sets the gain correctly, matching the ampis-sensittività tad-dħul tal-lifier għall-output tal-unità ewlenija tiegħek.

6.2 Crossover and Phase Adjustments

• LOW PASS Filter: Adjust this control to set the upper frequency limit for your subwoofer. A common starting point is between 80Hz and 120Hz, depending on your main speakers and personal preference.
• SUB SONIC Filter: This filter removes frequencies below the audible range that can waste amplifier power and potentially damage subwoofers. Set it typically between 20Hz and 30Hz, or slightly below your subwoofer's resonant frequency.
• Boost Bass: Use this control sparingly to enhance bass impact. Excessive bass boost can lead to distortion and potential damage. Start at 0dB and increase gradually if desired.
• FAŻI (0°/180°): Experiment with this switch to find the setting that provides the most coherent and impactful bass response. Listen from your normal listening position and choose the setting where the bass sounds loudest and most integrated with your front speakers.

7. Manutenzjoni

• Żomm il- ampIl-lavatur ikun nadif u ħieles mit-trab. Uża drapp artab u niexef għat-tindif.
• Tiżgura li l- amplifier's cooling fins are not obstructed to maintain proper ventilation.
• Periodically check all wiring connections for tightness and corrosion. Loose connections can cause performance issues or damage.
• Evita li tferra’ likwidi fuq ampaktar ħaj.
