5. Setup

Follow these steps to set up your Vincent PHO-200 Phono Preamplifier:

1. Placement: Place the PHO-200 on a stable, level surface. Ensure it is away from direct sunlight, heat sources, and other electronic devices that might cause interference. Allow adequate space for ventilation around the unit.
2. MM/MC Selection: Before making any connections, locate the MM/MC switch on the bottom of the PHO-200. Set this switch according to the type of cartridge installed on your turntable (Moving Magnet or Moving Coil). It is crucial to set this correctly for proper sound and to avoid potential damage.
3. Connect Turntable: Connect the RCA output cables from your turntable to the IN (L/R) RCA jacks on the rear panel of the PHO-200. Ensure the left channel (white/L) and right channel (red/R) are connected correctly.
4. Connect Ground Wire: Connect your turntable's ground wire to the GND terminal on the rear panel of the PHO-200. This helps to reduce hum and noise.
5. Connect to Amplifier: Connect the OUT (L/R) RCA jacks on the rear panel of the PHO-200 to a line-level input on your main amplifier (e.g., AUX, CD, TUNER, LINE IN). Do not connect the PHO-200's output to an amplifier's dedicated PHONO input, as this will result in over-amplification and distorted sound.
6. Connect Power Supply: Connect the external power supply unit to the POWER input jack on the rear panel of the PHO-200. Then, plug the power supply into a suitable wall outlet. The external power supply is designed to minimize electrical interference.

6. Operating Instructions

Once all connections are securely made and the MM/MC switch is correctly set:

1. Power On: Flip the power switch on the front panel of the PHO-200 to the 'ON' position. The power indicator LED will illuminate.
2. Select Input: On your main amplifier, select the input to which the PHO-200 is connected (e.g., AUX, CD).
3. Play Record: Begin playing a record on your turntable as you normally would.
4. Adjust Volume: Adjust the volume level using the volume control on your main amplifier. The PHO-200 does not have its own volume control.
5. Power Off: When finished listening, flip the power switch on the front panel of the PHO-200 to the 'OFF' position.

7. Maintenance

To ensure the longevity and optimal performance of your PHO-200:

• Cleaning: Disconnect the power supply before cleaning. Use a soft, dry cloth to wipe the exterior of the unit. Do not use liquid cleaners, abrasive cloths, or chemical solvents, as these may damage the finish.
• Ventilation: Ensure that the ventilation openings are not obstructed.
• Storage: If the unit will not be used for an extended period, disconnect the power supply and store it in a cool, dry place, away from dust and extreme temperatures.

8. Troubleshooting

If you encounter any issues with your PHO-200, please refer to the following troubleshooting guide:

• No Sound:
  • Ensure the PHO-200 is powered on (LED indicator illuminated).
  • Check all RCA cable connections between the turntable, PHO-200, and amplifier.
  • Verify that the correct input is selected on your main amplifier.
  • Confirm the MM/MC switch on the bottom of the PHO-200 is set correctly for your cartridge type.
  • Check if your turntable is functioning correctly.
• Humming or Buzzing Noise:
  • Ensure the turntable's ground wire is securely connected to the GND terminal on the PHO-200.
  • Check for loose RCA cable connections.
  • Move the PHO-200 and its cables away from other electronic devices (e.g., power transformers, Wi-Fi routers) that might cause electromagnetic interference.
  • Ensure the external power supply is used and properly connected.
• Distorted Sound:
  • Verify that the MM/MC switch on the bottom of the PHO-200 is set correctly for your cartridge type. An incorrect setting can cause distortion.
  • Ensure the PHO-200 is connected to a line-level input on your amplifier, not another phono input.
  • Check for damaged or faulty RCA cables.
  • Ensure your turntable's cartridge and stylus are in good condition and properly aligned.
