5. Namestitev
5.1 Montaža Amplifier
Izberite mesto za montažo, ki je suho, dobro prezračeno in varno. Zagotovite zadosten pretok zraka okoli amplifier to prevent overheating. The amplifier can be mounted horizontally or vertically. Use the provided mounting screws to secure the amplifier to a solid surface in your vehicle.
5.2 Žične povezave
Proper wiring is crucial for optimal performance and safety. Refer to Figure 3 for terminal locations.
- Napajalni priključek (+12V): Run a heavy-gauge power cable (e.g., 4-gauge or larger) directly from the vehicle's positive battery terminal to the amplifier's +12V terminal. Install an in-line fuse holder with an appropriate fuse (not included) within 18 inches (45 cm) of the battery.
- Ozemljitvena povezava (GND): Napeljite debel ozemljitveni kabel (enakega premera kot napajalni kabel) od ampOzemljitveni priključek napajalnika priključite na čisto, nepobarvano kovinsko površino na šasiji vozila. Zagotovite dobro električno povezavo tako, da postrgate morebitno barvo ali rjo. Ozemljitveni kabel mora biti čim krajši, idealno krajši od 1 metra.
- Priključek za daljinski vklop (REM): Priključite žico manjšega premera (npr. 18-kaliber) iz amplifier's REM terminal to the remote turn-on output of your head unit. This wire tells the ampvklopi se, ko je glavna enota aktivna.
- Vhodna povezava RCA: Connect RCA cables from the pre-out outputs of your head unit to the INPUT RCA jacks on the amplifier.
- Povezava zvočnikov: Connect your subwoofer(s) to the SPEAKER output terminals. Ensure correct polarity (+ to + and - to -). The amplifier is stable down to 1 Ohm. Consult your subwoofer's specifications for proper wiring configurations to achieve the desired impedance.
- Daljinski gumb za bas: Plug the remote bass knob cable into the REMOTE port on the amplifier and mount the knob in a convenient location for adjustment.
6. Delovanje
6.1 Začetni vklop
After all connections are made and verified, reconnect the vehicle's battery. Turn on your head unit. The POWER LED on the amplifier should illuminate. If the PROTECT LED illuminates, refer to the Troubleshooting section.
6.2 Prilagoditev Amplifier nastavitve
Adjust these settings carefully to optimize sound quality and prevent damage to your speakers.
- DOBITE: Start with the GAIN control at minimum. Play a familiar piece of music at a moderate volume on your head unit. Slowly increase the GAIN until you hear distortion, then back off slightly. This sets the ampvhodno občutljivost ojačevalnika prilagodite izhodu vaše glavne enote.
- LPF (nizkoprepustni filter): Adjust the LPF to filter out frequencies above your desired subwoofer range. A common starting point is 80-100 Hz. This ensures only low frequencies are sent to your subwoofer.
- SUBSONIC Filter: This filter removes extremely low frequencies that your subwoofer cannot reproduce efficiently, preventing damage and improving sound quality. Set it slightly below your subwoofer's port tuning frequency or around 25-30 Hz for sealed enclosures.
- BASS BOOST FREQ & BASS BOOST: Use these controls to enhance bass output at a specific frequency. Start with Bass Boost at 0 dB and adjust only if needed. Excessive bass boost can cause distortion and damage.
6.3 Daljinski gumb za nizke tone
