If the mixer has unbalanced inputs and stated above, you just connect to those inputs. The mixer has the electronics to handle the signal. No reason to put more electronics in front of the mixers circuits.
Impedance matching and using the correct signal levels are very important. If the impedance is mis-matched, it can cause problems with noise, frequency response, signal level and more. This stuff isn't made to mix & match, randomly.
