A crucial component in vinyl playback systems, a device is required to boost the extremely low-level signal generated by a turntable’s cartridge to a level suitable for amplification by a receiver or amplifier. This process ensures the audio signal is strong enough to be processed without significant noise interference. Without this amplification stage, the audio output would be virtually inaudible.
The necessity stems from the Recording Industry Association of America (RIAA) equalization standard applied during vinyl mastering. This standard reduces low frequencies and boosts high frequencies to maximize recording time and reduce groove size. The aforementioned device reverses this equalization curve during playback, restoring the original tonal balance of the recording. Its integration into a system allows for the proper reproduction of vinyl recordings, delivering the intended artistic expression of the music.
