An audio component integrating the functions of a preamplifier, amplifier, and tuner, designed to receive and amplify signals from various audio sources, including turntables. It allows users to connect a record player directly without requiring an external phono preamplifier. This device provides the necessary amplification and equalization (RIAA equalization) to properly reproduce the audio signal from vinyl records. For example, connecting a turntable directly to the designated input bypasses the need for a separate component to boost the low-level signal from the record cartridge.
The significance of this functionality lies in its ability to simplify audio setups for vinyl enthusiasts, consolidate equipment, and maintain signal integrity. Historically, the inclusion of this feature was standard on many audio receivers, reflecting the prominence of vinyl records as a primary audio source. As digital audio formats gained popularity, the feature became less common but has experienced a resurgence in recent years, mirroring the renewed interest in vinyl playback. This resurgence demonstrates a commitment to preserving the authentic sound and tactile experience associated with analog audio.
