Roswell Pro Audio Mini K67x Condenser Microphone
Large diaphragm condenser microphone featuring a proprietary 34mm capsule design, vintage circuit design with custom output transformer, and hand-selected, audiophile-grade capacitors for a transformer-rich sound loaded with harmonics, air, and character
The Roswell Pro Audio Mini K67x expands the promise of "sonic diversity" by introducing a new sound to the Mini K product line. The capsule voicing strikes a balance between neutrality and flattery, with tight bass and an open top end. The circuit enhances the source with harmonics. The mic retains the "point and shoot" simplicity of the Mini K lineup.
The mic's name, "K67x," refers both to the capsule design and circuit topology. The capsule is based on the K67, although Roswell built and voiced it with some proprietary tricks to create a sound unlike any other K67 capsule. The "x" in the model name refers to the transformer-coupled circuit, which gives the mic its trademark harmonic saturation.
This combination introduces a new color to the Mini K product line. The mic is not overtly colored, like the Mini K47, nor is it quite as flat and neutral as the Mini K87. The sonic inspiration for this model was the workhorse tube mic of the 1960s, which offered wideband frequency response and harmonics. This incarnation retains those characteristics.
Every Roswell microphone is subjected to a 24-hour "burn-in" on Roswell's 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 our facility.
The Mini K67x has a durable gray metallic paint finish. Each mic ships with our exclusive Cutaway shock mount, Roswell branded microfleece mic sock, and an upgraded flight case.
DESIGN AND COMPONENTS
The Mini K67x introduces two unique new sounds to the Mini K product line: the capsule voicing, and the harmonic saturation of the circuit.
Mini K67xThe capsule is a 34mm (large diaphragm) design. As the mic's name suggests, the capsule is nominally a K67 type, but Roswell invested two years' worth of research and development to create a proprietary, "Holy Grail" voicing: full bass without wooliness, slight attenuation in the sibilance range, neutral highs, and extended "air" above 10 kHz.
The circuit design borrows from Roswell's 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 a custom wound output transformer (which barely fits inside the mic body).
The capacitor on the JFET source is a critical component to the mic's sound. Roswell 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 K67x 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.
