Expert Audio Engineering Commentary

Gain Staging Advice

The odd one out in the AIR line: mains-powered, 62 dB of gain, and a +14 dBu input ceiling — twelve decibels more headroom than the bus-powered models, which sit at +1.5 dBu. 160 mW into 32 Ω is 2.26 V and the published unloaded ceiling is +15 dBu (4.36 V), so this is the only AIR that will drive 250 Ω headphones properly.

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.

Measurement conditions
«Preamp EIN -137 dBu (40 Ω source, A-weighted) -129 dBu (150 Ω source, unweighted)»

Two equivalent-input-noise figures for one preamp, 8 dB apart, because the source impedance and the weighting differ. A 40 Ω source is thermally about 6 dB quieter than a 150 Ω one, and A-weighting removes a further two to three decibels, so -137 dBu cannot be set beside the -128 dBu that most makers print for 150 Ω. The catalogue stores the 150 Ω unweighted figure, which is the comparable one.
