Introduction to Preamps
A preamp is an electronic device that amplifies the low-level signal produced by a turntable’s cartridge, allowing it to be processed by a receiver, amplifier, or other audio equipment. The primary function of a preamp is to boost the phono signal to a level that is compatible with the input requirements of the connected device. Without a preamp, the signal from the turntable would be too weak, resulting in a lackluster sound that fails to do justice to the music.
How Preamps Work
The preamp works by taking the low-level signal from the turntable’s cartridge and amplifying it to a line-level signal, which is then sent to the receiver or amplifier. This process involves several stages, including:
Signal Amplification
The preamp amplifies the signal from the turntable, increasing its voltage and current to a level that is sufficient to drive the connected device. This amplification process is critical, as it enables the signal to be processed and enhanced by the receiver or amplifier.
Equalization
In addition to amplification, preamps also apply equalization (EQ) to the signal. EQ is a process that adjusts the frequency response of the signal to compensate for the inherent characteristics of the vinyl format. The most common EQ curve used in preamps is the RIAA (Recording Industry Association of America) curve, which is specifically designed to correct for the bass boost and treble cut that occurs during the vinyl recording process.
Types of Preamps
There are several types of preamps available, each with its own unique characteristics and advantages. The most common types of preamps include:
Preamps can be integrated into the turntable itself, or they can be separate units that connect between the turntable and the receiver or amplifier. Some preamps are also built into receivers or amplifiers, providing a convenient and space-saving solution.
Phono Preamps
Phono preamps are specifically designed for use with turntables and are typically optimized for the RIAA EQ curve. They are available in a range of formats, including standalone units, integrated circuits, and even software plugins.

What is a preamp for a turntable and how does it work?
A preamp, short for preamplifier, is an electronic device that amplifies the low-level audio signal produced by a turntable to a level that is strong enough to be processed by a receiver, amplifier, or other audio equipment. The preamp is typically connected between the turntable and the amplifier or receiver, and its primary function is to boost the phono signal to a line-level signal. This is necessary because the signal produced by a turntable is relatively weak and requires amplification to be audible through speakers or headphones.
The preamp works by using a combination of amplification and equalization to boost the audio signal. It applies a standardized equalization curve, known as the RIAA curve, to the audio signal to compensate for the equalization applied during the recording process. This ensures that the audio signal is accurately reproduced and sounds clear and balanced. Additionally, the preamp provides a gain stage that amplifies the signal to a level that is suitable for the connected equipment. By using a preamp, users can enjoy high-quality audio from their turntable and take full advantage of their vinyl collection.
