CardioidRoswell Pro Audio Mini K67x

Cardioid Condenser Microphone

The Mini K67x is the 4th mic in Roswell’s Mini K lineup. It introduces a third distinct voice to the line, and pioneers the use of a new capsule design and voicing.

The mic is a large-diaphragm condenser. It retains the familiar body size and shape of the Mini K series.

The capsule is described as a K67 type, with a proprietary tuning. While most K67 capsules have a rising frequency response that can peak as high as +6dB in the 10-12kHz region, the K67x capsule is within 1dB of flat to 12kHz. It therefore requires no in-circuit corrective EQ filtering, which enables the mic to have a very gradual and natural rolloff in the high frequencies.

The circuit borrows from the company’s flagship mic, the Colares. It is a single-stage JFET topology with an oversized output transformer.

As is true of all Roswell microphones, all audio circuit components were selected for their contribution to the sound of the mic. This includes discontinued/NOS European-made capacitors, precision audio resistors, and a NOS JFET that is manually and individually “biased” to optimize its distortion and SPL performance within this circuit.

Notably, the K67x is built by hand in California. Every microphone is tested for frequency response, noise, and distortion, as part of the QC and burn-in process.

The mic ships with Roswell’s Cutaway™ shockmount in an upgraded flight case.

The K67x is available as a factory matched stereo pair; the paired mics are selected to be within 0.5dB in sensitivity (measured at 1kHz) and within 1.5dB from 50 Hz to 15kHz. The pair mics also have an internal pad switch, which provides 10dB additional headroom for recording louder sources such as drums.
