Speċifikazzjonijiet
Speċifikazzjonijiet tekniċi dettaljati għall- ampmodulu liifikatur:
| Parametru | Valur |
|---|---|
| Vol Operattivtage | 5V-12V DC (Voltage below 5V will significantly reduce sound; do not exceed 15V) |
| Kurrent Operattiv | 1mA (static) ~ 150mA (max) |
| Output Speaker Impedance | 4 Ω - 32 Ω (Higher impedance results in higher efficiency) |
| Supported Speaker Power | 0.5W-25W (Any power speaker can be used, volume is not directly proportional to speaker power, as long as it's greater than amplifier output rating) |
| Qawwa massima tal-Ħruġ | 750mW |
| Appoġġ tal-Input | Electret microphone, condenser microphone, moving coil microphone, audio signal |

Setup
Segwi dawn il-passi biex twaqqaf tiegħek b'mod korrett ampbord tal-lifer:
- Qabbad il-Mikrofonu: 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.
- Qabbad l-Ispeaker: 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).
- Qabbad l-Enerġija: Connect a DC power supply (5V-12V) to the positive and negative terminals of the ampbord aktar ħaj. WARNING: Do not reverse the polarity of the power supply, as this will damage the module.

Istruzzjonijiet Operattivi
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.
- Aġġustament tal-Volum: 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.
- Kompatibbiltà tad-dħul: Il- amplifier is designed to work with electret, condenser, and moving coil microphones, as well as general audio signals.

Manutenzjoni
To ensure the longevity and optimal performance of your DKARDU Mini Microphone Amplifier Board, consider the following maintenance guidelines:
- Żomm Niexef: Protect the module from moisture and liquids, as water can cause short circuits and damage components.
- Naddaf bil-mod: If cleaning is necessary, use a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Immaniġġja b'Kura: The board contains delicate electronic components. Avoid dropping or subjecting it to strong impacts.
- Ħażna xierqa: Meta ma tkunx qed tużah, aħżen il-modulu f'post frisk u niexef, 'il bogħod mix-xemx diretta u minn temperaturi estremi.
Issolvi l-problemi
Jekk tiltaqa' ma' problemi bil- ampbord tal-lifer, irreferi għall-problemi u s-soluzzjonijiet komuni li ġejjin:
- 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.
- Tiżgura l-provvista tal-enerġija voltage is within the 5V-12V range. Voltage below 5V will result in significantly reduced sound.
- Iċċekkja li l-konnessjonijiet kollha huma siguri u korretti skont id-dijagramma tal-wajers.
- 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.
- Tiżgura l-input voltage ma jaqbiżx 15V.
