btw, to play a turntable, you will need two specific electronic things to occur:
1. phono signal equalization (RIAA curve)
2. phono signal boost (preamp).
many amps do not include phono inputs/phono equalization/phono signal strength boost, they only accept 'line level' signals (think 1 volt), like tuners, tape decks, .....
1. equalization: boost the lows and cut the highs
a. the lows are cut during recording (keeps grooves smaller, that is how they got more grooves on a platter, more music on a 12" disk. i.e. Long Play, i.e. LP.
b. the highs are boosted during recording.
Eventually RIAA curve was standardized: defined agreed amounts of alteration during recording and corresponding re-equalization during playback.
2. Preamplification. Original tuners and ceramic cartridges produced around 1 volt directly into amps. New stereo MM moving magnet cartridges produce a lower signal, half or often less strong. That weaker signal has to boosted (preamp) up to 1 volt, then sent to your amp designed to receive/boost a 1 volt signal strength enough for your speakers.
3. IF you choose a Moving Coil cartridge, they in turn produce an even weaker signal, and they need a pre-pre amp, to get up to the MM signal strength, then the 'normal' pre-amp boost up to 1 volt. A few High Output Moving Coil cartridges exist, they are 'strong enough or just strong enough' to go into a MM phono input
many new moderately priced TT have an optional/switchable built in phono eq/preamp, so you can use it and go into a 'line' input, or not use it and go to your external phono eq/pre-amp.
