The Mini K47 is built into a body used by several other manufacturers. But it differs extensively from those lookalike microphones, in its components, its performance, and its sound.
The most significant difference is in the capsule. While competing models use either a small-diaphragm capsule or an undersized 32mm K67 type, the Mini K47 -- as its name states -- uses 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 no K67-based microphone can ever achieve: beautiful midrange detail with a neutral, rather than a hyped, top end.
Most of the condenser microphones 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.
