Connecting guitar to Behringer MIC2200

Contributor - Level 1

Recently I bought preamp Behringer Pro MIC2200 and I wonder if I can plug my guitar straight to it with a help of jack 1/4" connector.

This preamp has switch MIC/LINE with mic having 3k impendance and line 60k impendance.
I wonder if 60k impendance for line input is enough to plug there a guitar.
I know that normally it's up to 1 milion impendance needed in the input when connecting a guitar.

However says I can use this unit as a DI box for a guitar and keyboards and boost it with "gain output" knob.
Will boosting my guitar signal with "gain input" knob change anything?
I would rather do it that way to avoid boosting some additional noise on the output.

Best regards
