The ADK Hamburg II-AU and the Vienna II-AU microphones feature two-way attenuation pads (8 dB and 16 dB) and high-pass filters (100 Hz or 160 Hz). They each have a typical equivalent noise level (A-weighted per IEC 286-4) < 15dB. The mics are based on a unique FET circuit that gradually saturates the signal (most condenser microphones clip abruptly).

The "AU" reflects the fact that they now boast a special Australian-designed capsule in addition to British Oxford transformers, and high-end Phillips Norelco Uber-FET. The mics operate on 48V phantom power, have a sensitivity of 10 mV/Pa= - 40 dBV (Hamburg) and 13mV/Pa = -38 dBV (Vienna) and have a typical equivalent noise level (A-weighted per IEC 286-4) < 15dB.
