 Phono input

Phono input is a set of input jacks, usually mini jacks or RCA connectors, located on the rear panel of a preamp, mixer or amplifier, especially on early radio sets, to which a phonograph or turntable is attached.Modern styli (phonograph needles) and phono cartridges give a very low level output signal of the order of a few millivolts which the circuitry amplifies and equalizes.
