Expert Audio Engineering Commentary
Gain Staging Advice
52 dB with the ceiling at +10 dBu — modest gain, generous headroom. PreSonus specifies the maximum input level at 0.5% THD+N rather than at clipping, which is a stricter condition than most of this batch uses and makes the number slightly conservative. Note that the headphone output is quoted at a 60 Ω load, not the usual 32 Ω; 60 mW there is 1.9 V, which is more voltage than most bus-powered boxes deliver.
