When setting up a vinyl playback system, one common question that arises is whether a phono preamp is necessary when using an integrated amplifier. An integrated amplifier combines a preamplifier and power amplifier in one unit, typically used for amplifying various audio sources. In this article, we will discuss the role of a phono preamp, its compatibility with integrated amps, and the factors to consider when deciding if a phono preamp is needed.
Understanding Phono Preamps: A phono preamp, also known as a phono stage or phono preamplifier, is a device that amplifies the low-level signal from a turntable’s cartridge to a line level suitable for an amplifier or receiver. It also applies the necessary equalization (RIAA curve) to restore the proper frequency response of vinyl records during playback. This equalization compensates for the way records are cut and ensures accurate sound reproduction.
Integrated Amplifiers and Phono Preamp: Some integrated amplifiers have a built-in phono preamp, commonly referred to as a “phono input” or “phono stage.” These integrated amps have the necessary circuitry to handle the low-level signal from a turntable directly, eliminating the need for an external phono preamp. If your integrated amplifier has a dedicated phono input, you can connect your turntable directly to that input without the need for an additional phono preamp.
Factors to Consider: When determining if you need a phono preamp with an integrated amp, consider the following factors:
- Integrated Amp Features: Check if your integrated amplifier has a dedicated phono input or built-in phono preamp. If it does, you can connect your turntable directly to that input without requiring a separate phono preamp.
- Turntable Output: Consider the output of your turntable. Some turntables have a built-in phono preamp, commonly referred to as a “phono line” or “phono output.” If your turntable has a built-in phono preamp, you can connect it to any line-level input on your integrated amplifier without needing an external phono preamp.
- Turntable without Phono Preamp: If your turntable does not have a built-in phono preamp and your integrated amplifier lacks a dedicated phono input, you will need an external phono preamp to amplify and equalize the turntable’s signal before connecting it to a line-level input on your integrated amp.
- Sound Quality: Consider the sound quality you desire. Some vinyl enthusiasts prefer using separate phono preamps, as dedicated external units may offer higher-quality components and better signal processing, leading to improved sound reproduction.
- Upgradability: If you plan to upgrade your turntable or integrated amp in the future, consider the flexibility of your system. Using a separate phono preamp allows you to easily switch or upgrade components without being tied to the integrated amplifier’s built-in phono stage.
Conclusion:
Whether you need a phono preamp with an integrated amplifier depends on the features of your integrated amp, the output of your turntable, and your preferences for sound quality and upgradability. If your integrated amplifier has a dedicated phono input or your turntable has a built-in phono preamp, you can connect them directly without requiring an external phono preamp. However, if your turntable lacks a built-in phono preamp and your integrated amp does not have a dedicated phono input, an external phono preamp is necessary to amplify and equalize the turntable’s signal. Consider these factors when setting up your vinyl playback system to ensure proper amplification and accurate sound reproduction.
