Înființat
Follow these steps to correctly set up your ampplacă de salvare:
- Conectați microfonul: 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.
- Conectați difuzorul: 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).
- Conectare alimentare: Connect a DC power supply (5V-12V) to the positive and negative terminals of the ampscândură mai vie. WARNING: Do not reverse the polarity of the power supply, as this will damage the module.

Instrucțiuni de operare
Once properly set up, the amplifier board will begin to amplify the audio signal from the connected microphone. The module supports various microphone types and can be integrated into different audio systems.
- Reglarea volumului: The board features a small potentiometer (labeled 'VOL') for adjusting the output volume. Use a small screwdriver or appropriate tool to carefully turn the potentiometer to achieve the desired volume level.
- Compatibilitate de intrare: The amplifier is designed to work with electret, condenser, and moving coil microphones, as well as general audio signals.

Întreţinere
To ensure the longevity and optimal performance of your DKARDU Mini Microphone Amplifier Board, consider the following maintenance guidelines:
- Păstrați uscat: Protect the module from moisture and liquids, as water can cause short circuits and damage components.
- Curățați ușor: Dacă este necesară curățarea, folosiți o cârpă moale și uscată. Evitați utilizarea substanțelor chimice dure sau a materialelor abrazive.
- Manipulați cu grijă: The board contains delicate electronic components. Avoid dropping or subjecting it to strong impacts.
- Depozitare adecvată: When not in use, store the module in a cool, dry place, away from direct sunlight and extreme temperatures.
Depanare
Dacă întâmpinați probleme cu ampplaca de alimentare, consultați următoarele probleme și soluții comune:
- 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.
- Asigurați-vă că sursa de alimentare 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.
- Module Not Functioning / Damaged:
- Verify that the DC power supply polarity is correct. Reversing the positive and negative connections will burn out the module.
- Asigurați-vă că volumul de intraretage nu depășește 15V.
