Phono PreampsThe electrical output from a turntable's cartridge is very low, and nowhere near the line level output from other components that an amplifier expects.
A seperate pre-amp is used to boost the signal from a turntable up to line level. Sometimes called a phono stage, the turntable pre-amplifier also equalizes the sound (applying what's known as an RIAA equalization). Like any pre amp, it can have a dramatic impact on the quality of sound. |
