Recreating a classic

Newly founded pro audio company United Studio Technologies has released its UT FET47. Featuring a large, custom-wound, ‘striped core’ (multi-alloy) output transformer designed by US audio transformer and inductor manufacturer, CineMag, to reproduce the harmonic signature of its original German counterpart, the microphone incorporates a Heiserman HZ-series ‘K47’ German-style capsule, a joint effort between Heiserman and United Studio Technologies. The design features dual-milled backplates that are matched and then physically joined to reportedly ensure a consistent performance between sides and between capsules. The capsule is made from precision-milled brass and skinned with gold-spluttered, six-micron NOS (Not Otherwise Specified) Japanese Polyethylene Terephthalate film that is said to meet the purity standards of laboratory-grade Mylar. The microphone body is produced from nickel-plated brass milled from a solid brass billet, and comes with a swivel arm for mounting. The circuitry includes NOS military-spec polystyrene capacitors and tested, original NOS Fairchild Field-Effect Transistors. No electrolytic capacitors are used anywhere in the microphone.
