Specifiche
Specifiche tecniche dettagliate per il ampmodulo lificatore:
| Parametro | Valore |
|---|---|
| Volume di eserciziotage | 5V-12V DC (Voltage below 5V will significantly reduce sound; do not exceed 15V) |
| Corrente di esercizio | 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) |
| Potenza massima in uscita | 750 mW |
| Supporto di input | Electret microphone, condenser microphone, moving coil microphone, audio signal |
| Dimensioni (LxWxH) | 20 x 12 x 6 mm / 0.79 x 0.47 x 0.23 pollici |

Impostare
Segui questi passaggi per impostare correttamente il tuo ampscheda di supporto:
- Collega il microfono: 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.
- Collegare l'altoparlante: 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).
- Connetti alimentazione: Connect a DC power supply (5V-12V) to the positive and negative terminals of the ampbordo dell'allevatore. WARNING: Do not reverse the polarity of the power supply, as this will damage the module.

Istruzioni per l'uso
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.
- Regolazione del volume: 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.
- Compatibilità di input: IL amplifier is designed to work with electret, condenser, and moving coil microphones, as well as general audio signals.

Manutenzione
To ensure the longevity and optimal performance of your DKARDU Mini Microphone Amplifier Board, consider the following maintenance guidelines:
- Mantenere asciutto: Protect the module from moisture and liquids, as water can cause short circuits and damage components.
- Pulisci delicatamente: If cleaning is necessary, use a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Maneggiare con cura: The board contains delicate electronic components. Avoid dropping or subjecting it to strong impacts.
- Conservazione corretta: Quando non in uso, conservare il modulo in un luogo fresco e asciutto, lontano dalla luce solare diretta e da temperature estreme.
Risoluzione dei problemi
Se riscontri problemi con il tuo ampscheda di lifier, fare riferimento ai seguenti problemi comuni e alle relative soluzioni:
- 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.
- Garantire l'alimentazione voltage is within the 5V-12V range. Voltage below 5V will result in significantly reduced sound.
- Verificare che tutti i collegamenti siano sicuri e corretti secondo lo schema elettrico.
- 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.
- Modulo non funzionante/danneggiato:
- Verify that the DC power supply polarity is correct. Reversing the positive and negative connections will burn out the module.
- Assicurare il volume di inputtage non supera i 15V.
