- Koneksyon pouvwa: Connect the +12V terminal to the vehicle's positive battery terminal using a heavy-gauge power cable (e.g., 4-gauge). Install an in-line fuse (not supplied) within 18 inches of the battery.
- Koneksyon tè: Connect the GND terminal to a clean, unpainted metal surface on the vehicle chassis using a heavy-gauge ground cable of the same size as the power cable. The ground point should be as short as possible.
- Limen Remote: Konekte tèminal REM lan ak pwodiksyon limen a distans inite prensipal ou a. Fil sa a siyalize amplimen lè inite tèt la aktif.
- Antre odyo: Connect the RCA audio cables from your head unit's pre-amp rezilta nan ampjack antre RCA lifer la.
- Sòti Oratè: Konekte oratè ou yo ak amplifier's speaker output terminals. Ensure correct polarity (+ to + and - to -). For bridged operation, refer to the specific bridging instructions in your head unit or speaker manual.
5. Operasyon Enstriksyon
5.1. Premye Limen
Apre tout koneksyon yo fin fèt epi verifye, rekonekte tèminal negatif batri machin nan. Limen inite prensipal ou a. ampLimyè a ta dwe limen, sa endike pa yon endikatè LED (si genyen).
5.2. Adjusting Gain and Crossover
La amplifier features adjustable gain controls to match the output of your head unit and crossover settings to optimize sound for your speakers.
- Akeri kontwòl: Start with the gain control set to minimum. Play a familiar track at about 75% of your head unit's maximum volume. Slowly increase the amplifier's gain until you hear distortion, then back off slightly.
- Kwazman (HPF/LPF): Adjust the High-Pass Filter (HPF) for full-range speakers to prevent low frequencies from distorting them. Adjust the Low-Pass Filter (LPF) for subwoofers to only allow low frequencies.
5.3. Bass EQ Control
The Bass EQ control allows you to boost low frequencies. Use this feature sparingly and adjust carefully to avoid speaker damage or excessive distortion. Start with the Bass EQ at its minimum setting and increase gradually to achieve the desired bass response.
6. Antretyen
JBL Stage GT90041 ampLifter a mande mwens antretyen. Swiv direktiv sa yo pou asire l dire lontan:
- Netwayaj: Siye detanzantan ampNetwaye deyò aparèy la avèk yon twal mou epi sèk. Pa sèvi ak pwodui chimik ki agresif oswa pwodui netwayaj abrazif.
- Vantilasyon: Asire w ke najwa refwadisman yo rete pwòp san pousyè ak debri pou kenbe yon bon disipasyon chalè.
- Koneksyon: Detanzantan, tcheke tout koneksyon fil elektrik yo pou asire yo byen fèm epi yo pa gen korozyon.
- Ranplasman Fuse: If a fuse blows, replace it only with a fuse of the same type and rating (30A). Using an incorrect fuse can cause damage or fire.
NAN. Depanaj
