Topic: Recording synthesizer with Babyface

Greetings, I want to record my synth via Babyface - first generation. The manual says:
"The analog input 2 can be switched in TotalMix between line (low impedance, balanced, at the breakout cable) and instrument (high impedance, unbalanced, TRS jack at the unit).

I can't find this option.
I connected 1/4 TRS Jack to Instrument input on the right side of the Babyface, but only option I got in Total Mix is instrument or 48 phantom.

Please help!
