To ensure that every Mini K47 microphone delivers superior performance out of the box, we test them extensively prior to shipping: for polarity, noise, frequency response, and sensitivity. We listen to every microphone before it leaves our facility.
The Mini K47 ships with our exclusive Cutaway shockmount and an aluminum flight case (new for Sept, 2017). This edition of the microphone has been upgraded internally and externally, with a tough powder-coated finish and refinements to both the audio and DC circuits.

Component Details
The most unique thing about the Mini K47 is its capsule: a true 34mm K47 type capsule, modeled after the capsule in the most famous microphone of all time. We selected this capsule because it delivers a sound that is impossible to achieve with any other capsule design: beautiful midrange detail with a neutral, rather than a hyped, top end.
Most of the condenser microphones priced under $800 use the 2SK170 JFET, a low-cost, general purpose amplifier that can sound good when configured properly. But it usually used in circuits where its very high input capacitance (Ciss, 30pF) acts like a hardwired pad: it reduces the mic's sensitivity, which effectively raises the mic's noise floor. We prefer a JFET with a much lower input capacitance. We bias each one individually within the microphone's circuit, to ensure the highest possible gain without distortion.
The input coupling cap is the first component most aftermarket "modders" would change, because so many condenser mics use a low-grade ceramic or generic polyester box film type in this critical position. For the Mini K47, we use a polystyrene part. Styrene capacitors are generally considered to be the most neutrally voiced, cleanest sounding capacitors.
The main signal capacitors in this circuit are polypropylene film types, imported from Germany.
This combination of components delivers a sonic profile that is much more musical and balanced than anything in its price category.
