Поставување
Follow these steps to correctly set up your ampлифирачка плоча:
- Поврзете го микрофонот: 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.
- Поврзете го звучникот: 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).
- Поврзете напојување: Connect a DC power supply (5V-12V) to the positive and negative terminals of the ampпожива табла. WARNING: Do not reverse the polarity of the power supply, as this will damage the module.

Упатства за работа
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.
- Прилагодување на јачината на звукот: 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.
- Влезна компатибилност: На amplifier is designed to work with electret, condenser, and moving coil microphones, as well as general audio signals.

Одржување
To ensure the longevity and optimal performance of your DKARDU Mini Microphone Amplifier Board, consider the following maintenance guidelines:
- Одржување на суво: Protect the module from moisture and liquids, as water can cause short circuits and damage components.
- Чистете нежно: If cleaning is necessary, use a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Ракувајте со внимание: The board contains delicate electronic components. Avoid dropping or subjecting it to strong impacts.
- Правилно складирање: Кога не е во употреба, чувајте го модулот на ладно и суво место, подалеку од директна сончева светлина и екстремни температури.
Решавање проблеми
Доколку наидете на проблеми со вашиот ampразводна плоча, погледнете ги следните вообичаени проблеми и решенија:
- 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.
- Обезбедете ја јачината на напојувањетоtage is within the 5V-12V range. Voltage below 5V will result in significantly reduced sound.
- Проверете дали сите врски се безбедни и точни според шемата за поврзување.
- 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.
- Обезбедете ја влезната јачинаtage не надминува 15V.
