1. はじめに
The rolls VP29 Phono Preamp 設計されている 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. 特徴
- RIAA イコライゼーション: Provides accurate RIAA equalization for vinyl playback.
- Input/Output Connectivity: Features RCA stereo inputs and outputs for standard audio connections.
- 追加出力: Includes a 1/4" TRS stereo output for versatile connectivity options.
- 電源アダプター: 専用電源アダプター付属ですぐにご使用いただけます。
- 信号 Amplification： 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接続手順
- ターンテーブルを接続する: ターンテーブルからのRCA出力ケーブルを 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.
- アース接続： If your turntable has a separate ground wire, connect it to the アース端子 on the rear panel of the VP29. This helps reduce hum and noise.
- オーディオシステムに接続: 接続する 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.
- 電源接続: 付属の電源アダプターを PWR INPUT (12-16 VDC) jack on the VP29. Then, plug the power adapter into a standard electrical outlet.
注記： ターンテーブルにフォノプレが組み込まれている場合amp, ensure it is switched off or bypassed before connecting to the rolls VP29. Using two phono preamps in series can lead to distorted audio.
