[UR22C] How to record a raw sound (unity gain)

Hi Steinberg team,

I have a condenser microphone: EMM-6 (Dayton audio) and I’m going to record raw sound with unity gain to analyze later.
However, I discovered that your Mic input’s gain specification ranges just from +6 dB to +60 dB.
Does it mean the minimum gain is +6dB (turn “INPUT 1 GAIN” knob toward left side) ?
If that’s true, are there any other solutions to get unity gain = 1 with UR22C tool and record a raw sound ?
Hopefully to receive your response soon.

Thank you.
