Introducción
This manual provides essential information for the proper setup, operation, and maintenance of your GODIYMODULES Dual NE5532 Preamplifier Board. This pre-amplifier is designed with two NE5532 operational amplifiers, dedicating one amplifier per channel for enhanced audio performance compared to single operational amplifier designs. It features a built-in single power supply to dual power supply chip, allowing it to function with a single power input while providing dual power supply characteristics internally. The board incorporates large-capacity filter capacitors and a rectifier circuit, enabling compatibility with both AC and DC power sources.
Lea este manual detenidamente antes de utilizar el producto para garantizar un rendimiento y una durabilidad óptimos.
Información de seguridad
- Asegúrese siempre de que el volumen de la fuente de alimentacióntage and polarity are correct before connecting to the board. Incorrect voltagLa falta de polaridad puede dañar el dispositivo.
- Avoid touching electronic components while the board is powered to prevent electric shock or damage to sensitive parts.
- Do not expose the board to moisture, extreme temperatures, or static electricity.
- Handle the board with care to prevent physical damage to components or solder joints.
- If you are unsure about any installation or operation step, consult a qualified technician.

Configuración
1. Conexión de la fuente de alimentación
El preamplifier board supports a wide range of power inputs:
- Vol. CAtage: 5 V a 16 V
- Vol DCtage: 6 V a 24 V
Connect your power source to the designated power input terminals on the board. Ensure correct polarity for DC power. The board is designed with a rectifier circuit and filter capacitors for stable operation with both AC and DC inputs.

2. Audio Input and Output Connections
Connect your audio source (e.g., microphone, audio player) to the "IN" terminals (L, GND, R) and your audio output device (e.g., amplifier, speakers) to the "OUT" terminals (L, GND, R). Use the provided signal lines or appropriate audio cables.
3. Magnification Adjustment (Optional)
The board features R1 and R5 as magnification setting resistors. The default magnification is approximately 5 times. You can adjust the magnification by changing these resistors.
- Rango de resistencia: 5kΩ to 100kΩ.
- A larger resistance value will result in higher magnification.
- If using plug-in resistors, carefully remove the original surface-mount chip resistors by soldering and then solder the new plug-in resistors onto the pads at both ends of the patch position.

Instrucciones de funcionamiento
1. Encender
Once all connections (power, audio input, audio output) are securely made, apply power to the board. An LED indicator (if present) should illuminate, indicating the board is powered.
2. Control de volumen
Adjust the potentiometer (rotary knob) on the board to control the output volume. Start with the volume at a low setting and gradually increase it to your desired level to avoid sudden loud sounds.
3. Reproducción de audio
Begin playing audio from your connected source. The preamplifier will boost the signal before sending it to your output device.
Mantenimiento
- Mantenga la placa limpia y sin polvo. Utilice un cepillo suave y seco o aire comprimido para limpiarla.
- Revise periódicamente todas las conexiones para asegurarse de que sean seguras.
- Store the board in a dry, cool environment when not in use.
- The NE5532 operational amplifier chips are socketed, allowing for easy replacement or upgrade with other pin-compatible ICs if desired.
Solución de problemas
- Sin sonido:
- Check all power and audio connections. Ensure they are firmly seated and correctly wired.
- Verifique que la fuente de alimentación proporcione el volumen correcto.tage (AC 5-16V or DC 6-24V).
- Ensure the audio source is playing and the output device is powered on and set to the correct input.
- Adjust the volume potentiometer on the board.
- Hum or Hissing Noise:
- Verifique la conexión a tierra adecuada de todos los componentes de audio.
- Ensure audio cables are shielded and not running parallel to power cables.
- Move the unit or cabling away from potential sources of electromagnetic interference (RFI), such as power transformers, motors, or wireless devices.
- Verify the power supply is stable and free from ripple.
- Sonido distorsionado:
- Reduce the input signal level if it is too high.
- Check the magnification setting (R1, R5 resistors); if it's too high for your application, consider reducing it.
- Ensure the output device (e.g., amplifier) is not overdriven.
