3.2 Audio Connections

1. Connect Turntable to Input: Use RCA (L/R) cables to connect the output of your turntable to the "INPUT" jacks on the PP555.
2. Connect Preamp to Audio System: Use RCA (L/R) cables to connect the "OUTPUT" jacks on the PP555 to a line-level input (e.g., AUX, CD, TAPE) on your amplifier, receiver, or powered speakers. The PP555 also features a 1/4'' output jack for additional connectivity.
3. Grounding (Optional but Recommended): If your turntable has a separate ground wire and you experience humming or buzzing, connect the turntable's ground wire to the "GND" screw terminal on the PP555. This helps to eliminate ground loop noise.

4. Operating Instructions

Once all connections are made and the preamp is powered on (indicated by the blue "ON" light), your Pyle PP555 is ready for use. The preamp automatically boosts the low-level phono signal from your turntable to a standard line-level, allowing it to be properly processed by your audio system.

• Ensure your audio system's input is set to the corresponding line-level input where the PP555 is connected.
• Adjust the volume on your amplifier or receiver as needed. The PP555 provides a consistent line-level output, so all volume control will be managed by your connected audio equipment.
• The ultra-low noise audio operation of the PP555 ensures a clear and clean signal, enhancing your vinyl listening experience.

6. Troubleshooting

• No Sound:
  • Ensure the power adapter is securely connected or a fresh 9V battery is installed. The "ON" indicator light should be illuminated.
  • Verify all RCA cables are correctly connected to the "INPUT" and "OUTPUT" jacks.
  • Check that your amplifier/receiver is set to the correct line-level input.
  • Confirm the volume on your audio system is turned up.
• Humming or Buzzing Noise:
  • Connect your turntable's ground wire to the "GND" screw terminal on the PP555. This is a common solution for ground loop issues.
  • Ensure all audio cables are in good condition and securely connected.
  • Position the preamp close to the turntable to minimize cable length and potential interference.
• Low Volume:
  • Confirm your turntable is connected to the "INPUT" of the PP555, not directly to a line-level input on your receiver, as the phono signal requires amplification.
  • Adjust the volume on your connected amplifier or receiver.
