Vinyl records have made a resurgence in recent years, with many music lovers rediscovering the warm, rich sound of analog music. To enjoy vinyl records, you’ll need a turntable, and an essential component of any turntable setup is a preamp or phono stage.
What is a Preamp or Phono Stage?
A preamp, also known as a phono stage, is an electronic device that amplifies the weak signal from a turntable cartridge to a level that can be processed by an amplifier or receiver. The signal from a turntable cartridge is very low, typically around 5mV, and needs to be amplified to around 150mV to be compatible with other audio components.
Why Do You Need a Preamp or Phono Stage?
Without a preamp, the sound from your turntable will be very quiet and distorted. The preamp not only boosts the signal level but also applies a specific equalization curve, known as the RIAA curve, to correct for the way that vinyl records are recorded. This equalization is essential for accurate sound reproduction.
Types of Preamps or Phono Stages
There are two main types of preamps: standalone preamps and preamps that are built into turntables or receivers. Standalone preamps are separate units that you connect between your turntable and amplifier. They offer more flexibility and often better sound quality than built-in preamps. Built-in preamps are convenient and can save you money, but they may not offer the same level of performance as standalone preamps.
Choosing a Preamp or Phono Stage
When choosing a preamp, consider the following factors:
-
Cartridge compatibility: Make sure the preamp is compatible with the type of cartridge you have, either moving magnet (MM) or moving coil (MC).
-
Sound quality: Listen to different preamps to find one that sounds good to you.
-
Features: Some preamps have additional features, such as adjustable gain and equalization.
-
Budget: Preamps range in price from around $50 to $1,000 or more.
Connecting a Preamp or Phono Stage
Connecting a preamp is simple. Just connect the turntable’s output to the preamp’s input, and then connect the preamp’s output to the amplifier’s input. Make sure you are using the correct cables, typically RCA cables.
Conclusion
A preamp or phono stage is an essential component for any turntable setup. It amplifies the weak signal from the turntable cartridge and applies the RIAA equalization curve, ensuring that your vinyl records sound their best.
