Opsætning
Follow these steps to correctly set up your ampLifier-bræt:
- Tilslut mikrofonen: 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.
- Tilslut højttaleren: 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).
- Tilslut strøm: Connect a DC power supply (5V-12V) to the positive and negative terminals of the amplivligere bræt. WARNING: Do not reverse the polarity of the power supply, as this will damage the module.

Betjeningsvejledning
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.
- Lydstyrkejustering: 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.
- Input kompatibilitet: De amplifier is designed to work with electret, condenser, and moving coil microphones, as well as general audio signals.

Opretholdelse
To ensure the longevity and optimal performance of your DKARDU Mini Microphone Amplifier Board, consider the following maintenance guidelines:
- Hold tør: Protect the module from moisture and liquids, as water can cause short circuits and damage components.
- Rengør forsigtigt: If cleaning is necessary, use a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Håndteres med forsigtighed: The board contains delicate electronic components. Avoid dropping or subjecting it to strong impacts.
- Korrekt opbevaring: Når modulet ikke er i brug, skal det opbevares et køligt og tørt sted, væk fra direkte sollys og ekstreme temperaturer.
Fejlfinding
Hvis du støder på problemer med din ampFor sikringsplade, se følgende almindelige problemer og løsninger:
- 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.
- Sørg for, at strømforsyningen voltage is within the 5V-12V range. Voltage below 5V will result in significantly reduced sound.
- Kontroller, at alle forbindelser er sikre og korrekte i henhold til ledningsdiagrammet.
- 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.
- Sørg for, at input voltage ikke overstiger 15V.
