Expert Audio Engineering Commentary
Tonal profile
The Solo 4th Gen user guide prints 57 dB of microphone gain, EIN −127 dBu and +9.5 dBu maximum mic input. That is not the 69 dB preamp in the 2i2 4th Gen guide. At speaking level an SM7B asks for about 59 dB, so this Solo is about 2 dB short.
Amplification Warning
Headphone output impedance is printed as 50 Ω, the same figure as the 2i2 4th Gen and not the 11 Ω of the 4i4. The power row on that table repeats the level in dBu (2.5 dBu into 33 Ω, 10 dBu into 300 Ω) and does not state milliwatts, so none are stored.
What the datasheet actually says
Quoted verbatim from the manufacturer’s own page, with the date we checked it. We state what is printed, not what anyone intended by it.
«Maximum Output Power 2.5dBu into 33Ω / 10dBu into 300Ω»
The headphone power row repeats the output-level line and keeps the unit dBu. Milliwatts are not printed, so the catalogue does not store a power figure.
