How to turn on Unity Gain on Pre Amp

I have a setting on my Lumin S1 streamer regarding a volume setting that I wanted to give a try. Can anyone please tell me how to set the McIntosh C2500 preamp to the suggested unity setting? I assume it would be a different term in the McIntosh manual. PS the Lumin has no remote so the McIntosh remote would still have to control the volume. Thanks

70% volume is unity gain.

C2500 at 70% volume after passthrough

Tone bypass is not HT bypass, its function is to deactivate tone control setting.

On the C2500, " Passthru " is HT bypass. To activate passthru, you need to sent a 12Volt single by an external source to the back panel "power control" "Pass-thru" jack via a 3.5mm stereo cable (see owner's manual page 4).

Once the "Passthru" function is activated, all front panel control knobs and buttons including volume control will be deactivated except the "output 1/2 buttoms" (see owner's manual page 25), and the volume level will be automatically set and lock into unity gain (70%?).
