Настройка

Выканайце наступныя дзеянні, каб правільна наладзіць ampдошка выратавальніка:

1. Падключыце мікрафон: 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.
2. Падключыце дынамік: 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).
3. Падключыце харчаванне: Connect a DC power supply (5V-12V) to the positive and negative terminals of the ampліфіерная дошка. WARNING: Do not reverse the polarity of the power supply, as this will damage the module.

Ліквідацыю непаладак

Калі ў вас узнікнуць праблемы з вашым ampплату выратавальніка, звярніцеся да наступных распаўсюджаных праблем і рашэнняў:

• Very Little or No Sound:
  • Check the polarity of the electret microphone connection to the 'IN' and 'GND' terminals. Reversing the polarity will significantly reduce or eliminate sound.
  • Пераканайцеся, што аб'ём блока харчаванняtage is within the 5V-12V range. Voltage below 5V will result in significantly reduced sound.
  • Verify all connections are secure and correct according to the wiring diagram.
• Self-Excited Noise (Feedback):
  • Ensure the speaker is positioned sufficiently far away from the microphone to prevent audio feedback.
  • Check for proper shielding of the microphone cable.
• Module Not Functioning / Damaged:
  • Verify that the DC power supply polarity is correct. Reversing the positive and negative connections will burn out the module.
  • Пераканайцеся, што ўвод voltage не перавышае 15В.
