6. Istruzzjonijiet ta' Setup

Konnessjoni tal-Provvista tal-Enerġija: Connect a DC 9-18V power supply to the "DC12-18V" terminals on the board. Ensure correct polarity: '+' to positive, '-' to negative.
Konnessjonijiet tal-Ispeaker:
- Connect your stereo speakers (Left and Right) to the "Speaker" terminals. Ensure correct polarity for each speaker.
- Connect your subwoofer to the "Sub+ Sub-" terminals.
- Recommended speaker impedance is 2/4/6/8Ω.
Konnessjoni tal-Input Awdjo: Agħżel wieħed mill-metodi li ġejjin:
- Input tal-Awdjo ta '3.5mm: Connect your audio source (e.g., smartphone, MP3 player, computer) to the 3.5mm audio jack on the board.
- 3P_2.54mm Terminal Input: Alternatively, use the 3P_2.54mm terminal for audio input, connecting Left, Right, and Ground signals from your source.
Qawwa Inizjali Mixgħula: After all connections are secure, apply power to the amplifier. A green LED may illuminate, indicating power.

9 Issolvi l-problemi

Problema	Kawża Possibbli	Soluzzjoni
Ebda output tal-ħoss	Ebda setgħa lill- ampaktar ħaj. Incorrect audio input connection. L-ispikers mhumiex konnessi jew difettużi. Il-volum tas-sors awdjo huwa baxx wisq jew immut.	Check power supply connections and ensure it's within 9-18V. Verify audio input cable is securely connected to the correct input (3.5mm or 3P terminal). Ensure speakers are correctly wired and functional. Increase volume on both the amplifier u s-sors tal-awdjo.
Ħoss distort	Volum għoli wisq, u qed jikkawża qtugħ. Sors awdjo ta' kwalità fqira. Nuqqas ta' qbil fl-impedenza tal-ispiker. Konnessjonijiet laxki tal-ispiker.	Reduce volume on the amplifier u/jew sors tal-awdjo. Ittestja b'sors awdjo differenti. Ensure speakers are within the recommended 2/4/6/8Ω range. Iċċekkja u waħħal il-konnessjonijiet kollha tal-wajers tal-ispikers.
Ampil-ħajja tisħon	Normal operation under heavy load. Ventilazzjoni insuffiċjenti. Speaker impedance too low.	Ensure adequate airflow around the heatsink. Verify speaker impedance is not below 2Ω. If overheating persists and causes shutdown, reduce volume or load.
