They can amplify the sound of your turntable or record player and improves its quality. But buying the right preamp is quite challenging. In this section, find some information and the factors to consider in order to buy a reasonable preamp for your stereo player.

 What is a stereo preamp?

A preamp is a middle man between the primary input source and the audio gear. Its major function is to amplify low-level signals to produce better sound quality. Most of the audio gears have a built-in preamp. However, if your audio device does not have one, you should buy the preamp separately in order to enjoy the improved music quality.

How to choose a stereo amplifier?

Before rushing to buy the right stereo amplifier, you must think about certain factors considerately.

Input

There must be at least one microphone input in a preamp. However, if you want to record something, you will need at least two inputs. Some devices also contain the line inputs. 

Gain Control

The general rule says that the greater the gain control is, the better will be the sound quality produced by the preamp. 60 dB gain is sufficient for most of the microphones.

Types of preamps

There are three types of preamps i.e. vacuum tubes, transistors, and integrated circuits. The vacuum tubes preamps contain tubes and valves. The preamps add harmonic distortion to the sound improving quality of music. 

Transistor preamps include transistors that work like tubes in a preamp. The major benefit of these transistors is their low cost, heat, and compact size. 

The integrated circuit refers to a board where all the circuits are installed on a single board.
