4. Konfigurazzjoni u Konnessjonijiet

Follow these steps to correctly set up your WWZMDiB XH-M543 ampbord tal-lifer:

1. Input ta' Enerġija: Connect a DC power supply ranging from 12V to 26V to the power input terminal. A 24V DC power supply is recommended for optimal performance. Ensure correct polarity (+ and -).
2. Input Awdjo: Connect your audio source (e.g., MP3 player, mobile phone, computer) to the audio input terminal. The board includes a TLO74C amplifier chip for pre-amplification of the input signal.
3. Riżultat tal-Kelliem: Connect your speakers to the audio output terminals. Pay close attention to the positive (+) and negative (-) poles for each channel. For best results, it is recommended to use professional stage speakers rated at more than 120W.

5. Istruzzjonijiet Operattivi

Once all connections are securely made and verified, you can begin operating the ampbord tal-lifer:

• Qawwa Mixgħul: Apply power to the DC input terminal. The amplifier should power on.
• Aġġustament tal-Volum: The board features separate volume adjustment potentiometers for the left and right channels. Rotate these potentiometers to adjust the output volume to your desired level.
• Daqq tal-awdjo: Start playing audio from your connected source. Sound should be output through the connected speakers.
• Itfi: Disconnect the DC power supply when the amplifier mhux qed jintuża.
