Shure SM57 through a Golden Age Pre-73 MkIV: which input on the MiniFuse 2, and what to do with the second gain knob
Yes. With the PRE-73 MKIV already in line, the MiniFuse 2 only has to supply about 0 dB of the 56 it publishes. About 56 dB of interface gain is still unused.
The hard gain is already done. The Golden Age Project PRE-73 MKIV sits in front of the Arturia MiniFuse 2, so the interface preamp is no longer the thing that has to rescue a quiet microphone.
Shure rates the SM57 at -56.0 dBV/Pa, the voltage from a loud 94 dB tone at the grille. A speaking voice is closer to 85 dB, so the preamp still has to find about 0 dB to land near −9 dBV. That −9 dBV figure is just a tracking level: high enough to use, with space before the converter clips.
Feed the interface from the booster's output and do not stack a second microphone preamp on top. Most inline boosters spend the 48 V themselves. That is fine for a dynamic. If this microphone is a condenser, read the booster's manual before you leave it in the chain: if it does not pass phantom, the capsule goes silent.
