The Roswell Mini K67x Microphone is a unique large-diaphragm condenser microphone, designed to excel on vocals and guitars.
The Roswell Mini K67x Microphone 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. Like all Roswell microphones, the Mini K67x is designed, assembled, and tested in California. The mic's name, "K67x," refers both to the capsule design and circuit topology. The capsule is based on the K67, although we've 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.
Design and Component Details
The circuit design borrows from our 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 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 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.
