This is not specified, it depends on your turntable, (if it has a pre-amp or not) and its connections. Here, to use these speakers, you will need to connect to AUX (jack). Maybe an adapter like this one could work: Value Stereo plug - 2x cinch (5 m, Entry level, 3.5 mm jack (AUX), RCA) if your turntable already has a pre-amp. :) If not, you will need to get one as well (pre-amp/DAC).
