Expert Audio Engineering Commentary

Headroom notes

Audient prints EIN as '129dB A-Weighted' - no minus sign and dB instead of dBu. Read as -129 dBu, the standard form; the sign is missing in their table, not in the measurement.

Gain staging

58 dB from the 8024 Class A preamp - a middle figure. It runs an SM7B only just, at the top of the knob, and the honest answer for that microphone is a booster or a 69 dB interface.

Amplification Warning

The headphone amplifier is the reason to buy this box: 5.46 V RMS into 600 Ohm, published as a measured voltage rather than a decibel figure. That is more drive than interfaces three times the price, and it will run 250-600 Ohm headphones properly.

Setups using this gear

250 Ω DT 770 from an iPad Air: the interface that can drive them needs the whole power budgetDoes the Sennheiser MD 421-II need a booster into the Audient iD4 MkII?Soyuz Launcher with a Shure Beta 57A: 26 dB from a transformer, and the same unwritten phantom questionAudient iD4 MkII with a Shure SM7B: two decibels short
