Технічні характеристики
Детальні технічні характеристики для ampмодуль lifier:
| Параметр | Значення |
|---|---|
| Робочий випtage | 5V-12V DC (Voltage below 5V will significantly reduce sound; do not exceed 15V) |
| Робочий струм | 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) |
| Максимальна вихідна потужність | 750 мВт |
| Вхідна підтримка | Electret microphone, condenser microphone, moving coil microphone, audio signal |
| Розміри (ДxШxВ) | 20 x 12 x 6 мм / 0.79 x 0.47 x 0.23 дюймів |

Налаштування
Follow these steps to correctly set up your ampплата рятувальника:
- Підключіть мікрофон: 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.
- Підключіть динамік: 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).
- Підключіть живлення: Connect a DC power supply (5V-12V) to the positive and negative terminals of the ampдошка підйому. WARNING: Do not reverse the polarity of the power supply, as this will damage the module.

Інструкція з експлуатації
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.
- Регулювання гучності: 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.
- Сумісність входів: The amplifier is designed to work with electret, condenser, and moving coil microphones, as well as general audio signals.

Технічне обслуговування
To ensure the longevity and optimal performance of your DKARDU Mini Microphone Amplifier Board, consider the following maintenance guidelines:
- Зберігати сухим: Protect the module from moisture and liquids, as water can cause short circuits and damage components.
- Обережно очищайте: If cleaning is necessary, use a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Обережно поводьтеся: The board contains delicate electronic components. Avoid dropping or subjecting it to strong impacts.
- Правильне зберігання: Коли модуль не використовується, зберігайте його в прохолодному, сухому місці, подалі від прямих сонячних променів та екстремальних температур.
Усунення несправностей
Якщо у вас виникли проблеми з вашим 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.
- Переконайтеся, що блок живлення обtage 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.
- Модуль не працює / пошкоджено:
- Verify that the DC power supply polarity is correct. Reversing the positive and negative connections will burn out the module.
- Переконайтеся, що вхід обtage не перевищує 15В.
