Roswell K47 capsule with large diameter single back plate
Vintage circuit design using Roswell T7 output transformer
Selected high-grade capacitors for audiophiles
Heavy, solid steel body with metallic indigo finish
Exclusive Cutaway non-resonant shock mount
A condenser microphone that combines the 47 capsule and the circuit magic of the Mini K67x.
The Mini K47x combines the circuit magic of the K47 capsule and the Mini K67x.
– K47 capsule midrange detail
– Tube-like harmonic saturation with transformer circuit
– Cutaway shock mount and flight case included
– The Mini K47x uniquely and attractively combines the characteristics of two of Roswell's most popular microphones, while retaining the "point-and-shoot" simplicity of the Mini K microphone family.
The Mini K47x was awarded the "Editor's Choice" award by Music Inc at the 2023 NAMM.
On quiet sources, the Mini K47x sounds similar to the Mini K47, but above 2kHz it sounds nearly 1dB flatter. For medium to loud sound sources, the K47x's circuitry is pushed into gentle saturation, adding harmonic complexity and richness to the microphone's sound. At the same time, sharp transients in the sound source are slightly rounded and softened, giving the K47x a sound reminiscent of a classic European tube mic, or even a 2-inch tape deck.
Like all Roswell microphones, the Mini K47x is assembled and tested in California. Made with premium components and meticulous care.
Please select all three: color, character, and tone.
This microphone's name "K47x" refers to its capsule design and circuit topology. The capsule is K47 type. The "x" refers to the transformer circuit that gives the microphone its characteristic overtone saturation.
All Roswell microphones undergo a 24-hour "burn-in" in our proprietary conditioning equipment and are thoroughly tested, including polarity, noise, frequency response, sensitivity, and more, before shipping. We also conduct an acoustic sweep test on each microphone and listen to it multiple times before shipping.
The Mini K47x has a durable metallic paint finish and is available in Metallic Indigo. Each mic comes with a unique Cutaway shock mount, Roswell branded microfleece mic sock, and an upgraded flight case.
Not a replacement or upgrade for Mini K47
Mini K47x is not a replacement for Mini K47. It's also not an "upgraded" Mini K47. It's a new design with a different sound than the Mini K47. Please check "FEATURES" for details.

DESIGN AND COMPONENT DETAILS
The Mini K47x capsule is a 34mm (large diameter) K47 design. Provides presence boost in the 4-6kHz range. The Mini K47x capsule is tuned for a gentler presence boost than the Mini K47. This gives the Mini K47x a slightly more relaxed sound, or in other words, a less "forward" sound.
The circuit design incorporates technology from our flagship model, Colares. Constructed with a single-stage JFET/transformer topology, centered around a selection of vintage European output capacitors, the best-sounding modern filter capacitors available, and a proprietary oversized T7 transformer with high nickel laminations. is built on.
The capacitor supplied to the JFET is an important element for the sound of the microphone. We designed a custom bipolar electrolytic capacitor with a special formulation of a special electrolyte first developed for the legendary Blackgate line.
Internal gain staging is carefully set for each individual mic to produce harmonic saturation at medium SPL. This allows the Mini K47x to evoke the sound of vintage tube mics, producing harmonics that complement the source, but without adding noise or compressing transients.
Although the K47x shares the circuit topology with the K67x, these circuits have implementation differences. This is because we treat each product as a complete system. Below are the main circuit differences from K67x.
The K47x uses a more colored type of resistor, while the K67x chooses the resistor for transparency.
All filter capacitors are different. Like the resistors, the K47x components are selected for color.
The K47x uses T7 transformers, while the K67x uses T9 transformers.
Compared to the Mini K47, the Mini K47x is designed with softer transients and higher saturation. The Mini K47 was designed with an emphasis on accurate transient response and extremely low distortion. The Mini K47x, on the other hand, incorporates second harmonic saturation for sonic enhancement. As a side effect of the saturation circuit, the mini K47x tends to compress transients slightly.
Both the Mini K47 and Mini K47x offer unique, unique sounds that deliver great results for vocals, piano, guitar, drum overheads, and more.
