A device used to amplify the low-level signal from a turntable cartridge to a level suitable for a standard amplifier or receiver. These preamplifiers, costing less than $200, provide an entry point into the world of vinyl audio. These units compensate for the RIAA equalization curve applied during vinyl record production, ensuring accurate sound reproduction.
The availability of affordable options allows individuals to enjoy vinyl records without substantial investment. Historically, phono preamplification was integrated into most stereo receivers. However, modern systems often require a separate phono stage, leading to the development and popularity of standalone units. This separation allows for dedicated circuit design optimized for vinyl playback.
