It’s best to leave the +12db for buffers as OT attenuates the recordings, probably has to do with other settings that affect gain…
These are the settings I use for “unity gain” so that the signal coming out of the OT is the same level as the signal hitting the inputs for the various OT monitoring methods. There’s probably other settings that work, I might get back to exploring that once I have my computer again. For these I used Logic’s meters on a signal coming direct from a Little Phatty, and then through the OT so that it hit the same level…
