  • A pre-amp is an electronic component used for signal boosting. They are used in guitar amplifiers, recording studios, and in home and car stereo systems. Stereo pre-amps are a more sophisticated version, and they do have advantages.

    System Matching

    Most pre-amps send a monaural, or mono, signal to a receiver or slave amp. The system receiving the signal must then split the signal into left and right channels. A stereo pre-amp serves this purpose, which provides an easier match for a stereo system to reproduce.

    Overall Sound Quality

    Source recordings, such as CDs, are recorded and mixed in stereo to begin with. Stereo pre-amps can more effectively send a truer signal to any system for an improved overall sound quality.

    Definition of Sound

    Splitting the signal in the pre-amp stage allows for a greater definition of the left and right spectrums of the source recording. This brings out more of the nuances that may be lost during the signal boosting stage in a stereo system.

    Tonal Range

    Stereo pre-amps generally come with separate equalization for both channels. This gives the user more control of treble and bass response, and it lends itself to better signal reproduction.

    Clarity

    Some source signals are inherently difficult to clarify, especially movie soundtracks. A stereo pre-amp in a home theater system can dramatically improve the distinction in spoken dialogue and sound effects, as well as in music scores.
