Жайгашуу
Туура орнотуу үчүн төмөнкү кадамдарды аткарыңыз ampкөтөргүч такта:
- Микрофонду туташтыруу: 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.
- Динамикти туташтыруу: 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).
- Туташуу кубаты: Connect a DC power supply (5V-12V) to the positive and negative terminals of the ampкуткаруучу такта. WARNING: Do not reverse the polarity of the power supply, as this will damage the module.

Техникалык тейлөө
To ensure the longevity and optimal performance of your DKARDU Mini Microphone Amplifier Board, consider the following maintenance guidelines:
- Кургак кармоо: Protect the module from moisture and liquids, as water can cause short circuits and damage components.
- Акырын тазалоо: If cleaning is necessary, use a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Этияттык менен мамиле кылуу: The board contains delicate electronic components. Avoid dropping or subjecting it to strong impacts.
- Туура сактоо: Колдонулбай турган учурда, модулду салкын, кургак жерде, күн нуру түз тийген жерден жана өтө жогорку температурадан алыс сактаңыз.
Проблемаларды чечүү
Эгер сиз менен көйгөйлөр пайда болсо ampкөтөргүч такта, төмөнкү жалпы көйгөйлөрдү жана чечимдерди караңыз:
- 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.
- электр менен жабдууну камсыз кылуу voltage 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.
- Модуль иштебейт / бузулган:
- Verify that the DC power supply polarity is correct. Reversing the positive and negative connections will burn out the module.
- Киргизүү көлөмүн камсыз кылыңызtage 15V ашпайт.
