GODIYMODULES Dual NE5532 Preampലൈഫയർ ബോർഡ് ഇൻസ്ട്രക്ഷൻ മാനുവൽ

ആമുഖം

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.

1. വൈദ്യുതി വിതരണ കണക്ഷൻ

പ്രീamplifier board supports a wide range of power inputs:

• എസി വോളിയംtage: 5V മുതൽ 16V വരെ
• ഡിസി വോളിയംtage: 6V മുതൽ 24V വരെ

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.

• പ്രതിരോധ ശ്രേണി: 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.

പ്രവർത്തന നിർദ്ദേശങ്ങൾ

1. പവർ ഓൺ

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. വോളിയം നിയന്ത്രണം

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. ഓഡിയോ പ്ലേബാക്ക്

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

• Keep the board clean and free from dust. Use a soft, dry brush or compressed air for cleaning.
• എല്ലാ കണക്ഷനുകളും സുരക്ഷിതമാണെന്ന് ഉറപ്പാക്കാൻ ഇടയ്ക്കിടെ പരിശോധിക്കുക.
• ഉപയോഗത്തിലില്ലാത്തപ്പോൾ ബോർഡ് വരണ്ടതും തണുത്തതുമായ അന്തരീക്ഷത്തിൽ സൂക്ഷിക്കുക.
• The NE5532 operational amplifier chips are socketed, allowing for easy replacement or upgrade with other pin-compatible ICs if desired.

ട്രബിൾഷൂട്ടിംഗ്

  • 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:
  • Check for proper grounding of all audio components.
  • 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.
• വികലമായ ശബ്ദം:
  • 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.
