Are the Octopre line inputs routed through the mic pre circuitry?

The line inputs are not routed through the mic pre amp section but through a line level amp and then through the filter, dynamics and converter. When the 'line' button is pressed in the level knob has a range of +/-10dB (12 o'clock position is unity gain). Line inputs are never routed through mic pre circuitry since a line level input impedance needs to be much higher than a mic input impedance.
