Tatūnga
A pee i enei taahiraa ki te whakarite tika i to amppapa whakaahuru:
- Honoa te hopuoro: 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.
- Honoa te Kaikōrero: 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).
- Hono Hono: Connect a DC power supply (5V-12V) to the positive and negative terminals of the amppoari ora. WARNING: Do not reverse the polarity of the power supply, as this will damage the module.

Nga Tohutohu Whakahaere
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.
- Whakaritenga Rōrahi: 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.
- Hototahi Whakauru: Ko te amplifier is designed to work with electret, condenser, and moving coil microphones, as well as general audio signals.

Te tiaki
To ensure the longevity and optimal performance of your DKARDU Mini Microphone Amplifier Board, consider the following maintenance guidelines:
- Kia maroke: Protect the module from moisture and liquids, as water can cause short circuits and damage components.
- Horoi Ataahua: If cleaning is necessary, use a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Te hapai me te tiaki: The board contains delicate electronic components. Avoid dropping or subjecting it to strong impacts.
- Rokiroki Tika: Ki te kore e whakamahia, rongoatia te waeine ki te wāhi hauhautanga, maroke, kia matara atu i te rā tika me te pāmahana tino kino.
Raparongoā
Mena ka pa ki a koe nga raru o to amppapa whakamātao, tirohia ngā raruraru me ngā otinga e whai ake nei:
- 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.
- Whakaritehia te 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.
- Whakaritea te voltage kore e neke ake i te 15V.
