ማዋቀር
በትክክል ለማዋቀር እነዚህን ደረጃዎች ይከተሉ ampየማጣሪያ ሰሌዳ;
- ማይክሮፎኑን ያገናኙ; Use a shielded cable to connect the electret microphone to the 'IN' and 'GND' terminals of the amplifier board. Pay close attention to the polarity of the electret microphone; incorrect polarity will result in very low or no sound.
- ድምጽ ማጉያውን ያገናኙ፡ Connect your speaker to the 'OUT' terminals of the amplifier board. Ensure the speaker is positioned away from the microphone to prevent self-excited noise (feedback).
- የግንኙነት ኃይል; Connect a DC power supply (5V-12V) to the positive and negative terminals of the ampየማብራሪያ ሰሌዳ። WARNING: Do not reverse the polarity of the power supply, as this will damage the module.
