PHAUN ribbon and dynamic microphone head-amplifier

+27dB of gain and super low-noise performance of 1nV per √Hz

The PHAUN is now only available to special order. Please contact for more details.


When an insensitive, ribbon or moving-coil microphone is used with a classic microphone preamplifier like the PHAB or the HYDRA, there is often the need to run the preamp' "flat-out" in order to get enough gain into the DAW interface. This is rarely an ideal condition. For this reason, we are introduced the new Phædrus Audio PHAUN, a fully balanced, class-A, super low-noise microphone head-amplifier to be used between the ribbon, or the moving-coil microphone and the PHAB or HYDRA preamplifiers, to:

The PHAUN takes its power from the preamp's phantom-power: it does not require its own power-supply. The unit is constructed with special, selected low-noise transisitors for the best possible noise performance. This is a discrete, class-A amplifer design and does not use op-amps. (Note, some manufacturers state that FETs are the "best low-noise device", but this is completely mistaken when the source has a low impedance like an electrodynamic microphone.) Depite the very low-noise design, the headroom is a massive +8dBu for 1% THD. Microphone loading options run from 50Ω to >10kΩ ensuring the maximum tonal options from a single microphone type.
