Expert Audio Engineering Commentary
Headroom notes
MOTU publishes no headphone output impedance and no headphone power, only the maximum level. The +12.5 dBu figure therefore says how loud, not how much current: with 32 Ohm planars treat it as unverified.
Gain staging
0 to +60 dB with -129 dBu EIN, and +12.5 dBu on the headphone output - the highest headphone voltage in this batch. For a quiet dynamic microphone it is a better bet than any 55-58 dB interface here, though still short of the 69-70 dB tier.
