Inputs on LINE LEVEL PREAMP that can be used for DIGITAL too, not only for analog. I use all 4 for analog only, but i have 2 turntables with 4 tonearms.
The OP own 3 tonearms, so he could connect each tonearm with separate phono stage (or sut and phono stage) to line level preamp.
It's not necessary to have a SUT with 3 inputs, it can be 3 different separate devices (SUT, Headamp or Phonostage) connected all together to ONE line level preamp
