A:Answer You need an amplifier or receiver that has a vinyl input, or else a preamp and an amp.. Vinyl players put out an extremely small signal, Same as a microphone. Amplifiers and receivers accept a "line level" signal that phonographs don't produce. So if there isn't a specific 'vinyl' or 'phono' input on you amp or receiver, you will need that preamp to boost the very low phonograph signal to an acceptable line level, which can then be amplified for the speakers.. Got it?!
