The Roswell Pro Audio Mini K47x provides a unique and compelling combination he circuit magic of the best-selling Mini K67x with the K47 capsule from the most popular mic in their catalog, while retaining the “point and shoot” simplicity of the Mini K mic family.

Like all Roswell microphones, the Mini K47x is assembled and tested in California, using the premium components and meticulous care for which Roswell is known.

• Midrange detail from the K47 capsule
• Tube-like harmonic saturation from the transformer circuit
• Includes Cutaway shock mount and flight case

COLOR, CHARACTER, TONE – PICK ANY THREE

The mic’s name refers both to the capsule design and circuit topology. The capsule is the K47, found in the best-selling Mini K47. The “x” refers to the transformer-coupled circuit, which gives the mic its trademark harmonic saturation.

Every Roswell microphone is subjected to a 24-hr “burn in” on a proprietary conditioning fixture, then tested extensively prior to shipping: polarity, noise, frequency response, sensitivity, and more. Roswell perform an acoustic sweep test and listen to every microphone multiple times before it leaves their facility.

DESIGN AND COMPONENT DETAILS

The Mini K47x capsule is a 34mm (large diaphragm) K47 design. It provides the familiar and expected rise in its frequency response in the 4-6kHz range, with a neutral top end.

The circuit design borrows from the flagship Colares microphone; it is a single-stage JFET/transformer topology, built around a selected vintage European-made output capacitor, the best-sounding modern filter capacitors on the market, and Roswell’s oversized T7 transformer with high nickel lamination.

The capacitor feeding the JFET is a critical component to the mic’s sound. We’ve designed a custom bipolar electrolytic, with a special formulation of electrolyte that was initially developed for the legendary Black Gate line of capacitors.

Internal gain staging is carefully set for each individual mic to produce harmonic saturation at moderate SPL. This allows the Mini K47x to evoke the sound of vintage tube microphones, creating harmonics to complement the source, although without adding noise or crushing transients the way some tube mics would.

While the circuit topology in the K47x is shared with the K67x, these circuits differ in implementation, because we treat each product as a complete system. Here are the main circuit differences from the K67x:

• The K47x uses a more colored type of resistor, while the K67x resistors were chosen for transparency
• All the filter capacitors are different formulations. As with the resistors, the K47x parts were chosen for color
• The K47x uses a T7 transformer, while the K67x uses a T9 transformer

FEATURES:
