Blender Inputs


I'm looking to fill my classroom with TC Helicon Blenders for students to be able to practice along with a mix that I'm running to each unit. Keys, Bass, Electric Drum kit, Vocals etc - but I cannot find any information regarding the inputs and if I will need DIs.

Considering I was looking at Roland HS-5's which are more complicated and triple the price, I'd love if I can just plug and play my basses, keys and microphones.
