GODIYMODULES Dual NE5532 PreampManuel d'instructions de la carte lifier

Introduction

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.

Veuillez lire attentivement ce manuel avant d'utiliser le produit afin d'en garantir des performances et une durée de vie optimales.

Consignes de sécurité

• Assurez-vous toujours que le volume de l'alimentation électriquetage and polarity are correct before connecting to the board. Incorrect voltagUne inversion de polarité peut endommager l'appareil.
• Avoid touching electronic components while the board is powered to prevent electric shock or damage to sensitive parts.
• Ne pas exposer la carte à l'humidité, aux températures extrêmes ou à l'électricité statique.
• Manipulez la carte avec précaution afin d'éviter d'endommager physiquement les composants ou les joints de soudure.
• If you are unsure about any installation or operation step, consult a qualified technician.

Installation

1. Connexion de l'alimentation

Le Preamplifier board supports a wide range of power inputs:

• Vol ACtage: 5 V à 16 V
• Vol CCtage: 6 V à 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.

• Plage de résistance : 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.

Mode d'emploi

1. Mise sous tension

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. Contrôle du volume

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. Lecture audio

Begin playing audio from your connected source. The preamplifier will boost the signal before sending it to your output device.

Entretien

• Keep the board clean and free from dust. Use a soft, dry brush or compressed air for cleaning.
• Vérifiez régulièrement toutes les connexions pour vous assurer qu'elles sont sécurisées.
• 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.

Dépannage

• Pas de son :
  • Check all power and audio connections. Ensure they are firmly seated and correctly wired.
  • Vérifiez que l'alimentation fournit le volume correcttage (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:
  • Vérifiez que tous les composants audio sont correctement mis à la terre.
  • 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.
• Son déformé :
  • 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.
