Gadzirira
Follow these steps to correctly set up your ampbhodhi rekuisa mwenje:
- Batanidza Maikorofoni: 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.
- Batanidza Mutauri: 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).
- Batanidza Simba: Connect a DC power supply (5V-12V) to the positive and negative terminals of the ampLifier board. WARNING: Do not reverse the polarity of the power supply, as this will damage the module.

Operating Instruction
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.
- Kugadziridza Vhoriyamu: 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 Kuenderana: The amplifier is designed to work with electret, condenser, and moving coil microphones, as well as general audio signals.

Maintenance
To ensure the longevity and optimal performance of your DKARDU Mini Microphone Amplifier Board, consider the following maintenance guidelines:
- Ramba Waoma: Protect the module from moisture and liquids, as water can cause short circuits and damage components.
- Chenesa Zvinyoro: Kana zvichidikanwa kuchenesa, shandisa jira rakapfava uye rakaoma. Dzivisa kushandisa makemikari akaomarara kana zvinhu zvinokwesha.
- Bata Nekungwarira: The board contains delicate electronic components. Avoid dropping or subjecting it to strong impacts.
- Kuchengetera Kwakakodzera: Kana isiri kushandiswa, chengeta module iyi munzvimbo inotonhorera, yakaoma, kure nezuva rakananga uye tembiricha dzakanyanya.
Kugadzirisa matambudziko
Kana iwe ukasangana nematambudziko neako amplifier board, refer to the following common problems and solutions:
- 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.
- Ita shuwa kuti magetsi emagetsi awandatage 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.
- Iva nechokwadi chekuisa voltage haipfuure 15V.
