2. Varnostne informacije
- Preden začnete z električnimi deli, vedno odklopite negativni pol akumulatorja vozila.
- Prepričajte se, da so vse žice pravilno napeljane in pritrjene, da preprečite poškodbe zaradi ostrih robov ali premičnih delov.
- Za napajalne in ozemljitvene priključke uporabite ožičenje ustreznega premera, kot je navedeno v razdelku o namestitvi.
- Install fuses as close to the battery as possible to protect against short circuits.
- Izogibajte se namestitvi ampIzogibajte se neposredni sončni svetlobi, prekomerni vročini, vlagi ali prahu.
- Če ste glede katerega koli dela postopka namestitve negotovi, se posvetujte s profesionalnim monterjem.
- Delovanje amplifier at extreme volumes for extended periods can cause hearing damage.
3. Nastavitev in namestitev
Proper installation is crucial for optimal performance and safety. The NVX XAD12 features a Pulse Width Modulated (PWM) MOSFET power supply and soft start turn-on circuitry.
3.1 Montaža Amplifier
The XAD12 is designed for surface mount installation. Choose a location that provides adequate ventilation and is protected from moisture and direct heat. Ensure there is sufficient space around the amplifier za kroženje zraka.

3.2 Napajalni priključki
Priključite napajalne, ozemljitvene in daljinske vklopne žice na amplifier's power input terminal block.
- +12V (napajanje): Connect a heavy-gauge power cable (e.g., 4 AWG or larger for 1500W RMS) directly from the positive terminal of the vehicle's battery. Install an appropriate fuse (not included) within 18 inches of the battery.
- REM IN (Remote Turn-On): Connect a 18-gauge wire from the remote turn-on output of your head unit or other switched 12V source.
- GND (ozemljitev): Connect a heavy-gauge ground cable (same gauge as power) to a clean, unpainted metal surface of the vehicle's chassis. Ensure a solid electrical connection.

3.3 Priključitev izhoda zvočnika
Connect your subwoofer(s) to the speaker output terminals. The XAD12 is 1-Ohm stable, allowing for flexible wiring configurations. Ensure the total impedance of your connected speakers does not fall below 1 Ohm.

3.4 RCA Input/Output Connections
Connect the RCA input cables from your head unit's subwoofer output to the amplifier's INPUT RCA jacks. If daisy-chaining multiple amplifiers, use the OUTPUT RCA jacks to send the signal to the next amplifier.

4. Upravljanje Amplifier
Once all connections are made and verified, you can power on your system and adjust the ampnastavitve lifierja.
4.1 Začetni vklop in nastavitev ojačanja
- Vklopite glavno enoto. amplifier should power on (indicated by the power LED).
- Nastavite amplifier's GAIN control to its minimum position.
- Play a familiar music track with a strong bass presence at about 75% of your head unit's maximum volume.
- Počasi povečujte regulator GAIN na amplifier until you hear distortion, then back it off slightly. The POWER/CLIP/PROTECT indicator can assist in setting the gain without clipping.

4.2 Crossover and Bass Boost Adjustments
- LPF (nizkoprepustni filter): Adjust this control to filter out high frequencies from your subwoofer. A common starting point is 80-100 Hz.
- SUBSONIC Filter: This filter removes extremely low frequencies that are below the audible range and can cause damage to your subwoofer. Set it slightly below your subwoofer's port tuning frequency or around 20-30 Hz.
- BASS BOOST: Use this control sparingly to enhance bass output. Excessive bass boost can lead to distortion and potential speaker damage. Start at 0dB and increase gradually if desired.

5. Vzdrževanje
- Čiščenje: Za čiščenje uporabite mehko, suho krpo ampzunanjost čistilnega sredstva. Ne uporabljajte agresivnih kemikalij ali abrazivnih čistil.
- Prezračevanje: Zagotovite amplifier's cooling fins are free from obstructions to maintain proper airflow. Periodically check for dust buildup.
- Povezave: Periodically inspect all power, ground, speaker, and RCA connections to ensure they are secure and free from corrosion.
