1. Introduktion
The rolls VP29 Phono Preamp er designet til amplify the RIAA equalized signal from a turntable to a standard line level. This allows turntables, which typically output a low-level, RIAA-equalized signal, to be connected to audio systems or receivers that lack a dedicated phono input. The VP29 ensures proper signal amplification and equalization for accurate audio reproduction from vinyl records.
2. Funktioner
- RIAA-udligning: Provides accurate RIAA equalization for vinyl playback.
- Input/Output Connectivity: Features RCA stereo inputs and outputs for standard audio connections.
- Yderligere output: Includes a 1/4" TRS stereo output for versatile connectivity options.
- Strømadapter: Comes with a dedicated power adapter for immediate use.
- Signal Ampliifikation: Converts low-level phono signals to line-level signals compatible with most audio equipment.

This image shows the rear panel of the rolls VP29. From left to right, it features the 1/4 inch TRS output jack, the RCA stereo input jacks (red for right, white for left), the RCA stereo output jacks (red for right, white for left), a ground terminal, and the power adapter input jack.
4.3 Tilslutningsprocedure
- Connect Turntable: Tilslut RCA-udgangskablerne fra din pladespiller til INPUT (RCA L/R) jacks on the rolls VP29. Ensure the red cable connects to the 'R' (Right) input and the white/black cable connects to the 'L' (Left) input.
- Jordforbindelse: If your turntable has a separate ground wire, connect it to the Jordterminal on the rear panel of the VP29. This helps reduce hum and noise.
- Tilslut til lydsystem: Tilslut OUTPUT (RCA L/R) jacks of the VP29 to an available line-level input on your amplifier, receiver, or powered speakers. Use an input labeled 'AUX', 'CD', 'Tuner', or 'Line In' (do not use a 'Phono' input on your receiver, as this would result in double amplification and incorrect equalization). Alternatively, use the 1/4" TRS Output to connect to compatible equipment.
- Strømtilslutning: Tilslut den medfølgende strømadapter til PWR INPUT (12-16 VDC) jack on the VP29. Then, plug the power adapter into a standard electrical outlet.
Note: Hvis din pladespiller har en indbygget phono preamp, ensure it is switched off or bypassed before connecting to the rolls VP29. Using two phono preamps in series can lead to distorted audio.
5. Betjening
Once all connections are securely made and the VP29 is powered on, you can begin playing your vinyl records. The VP29 operates automatically, providing the necessary amplification and RIAA equalization. There are no user-adjustable controls on the unit.
- Place a record on your turntable.
- Sænk tonearmen ned på pladen.
- Juster lydstyrken på din tilsluttede amplifier or receiver to your desired listening level.

7. Fejlfinding
If you encounter issues with your rolls VP29 Phono Preamp, se følgende almindelige problemer og løsninger:
- Ingen lyd:
- Ensure the power adapter is securely connected to the VP29 and a working electrical outlet.
- Verify all RCA and 1/4" TRS cables are correctly and firmly connected to both the turntable, VP29, and your audio system.
- Check that your audio system is set to the correct input source (e.g., AUX, CD, Line In).
- Confirm your turntable's built-in preamp (if any) is bypassed or switched off.
- Brummen eller summende støj:
- Ensure the turntable's ground wire is connected to the VP29's ground terminal.
- Tjek for løse kabelforbindelser.
- Move the VP29 and associated cables away from power cords, transformers, or other electronic devices that may cause interference.
- Test with different RCA cables to rule out faulty cabling.
- Distorted or Overly Loud Sound:
- Ensure you are not connecting the VP29 to a 'Phono' input on your receiver, as this will result in double amplification. Connect to a 'Line In' type input.
- Verify your turntable's output is a standard phono level and not already line-level.
