The Roswell Pro Audio Mini K87 is a high-resolution large-diaphragm condenser microphone designed for engineers, producers, musicians, and content creators who need detailed, natural sound without excessive coloration. Featuring a specially tuned K67/K87-style capsule and a low-noise transformerless circuit, the Mini K87 delivers balanced clarity, smooth top end, and exceptional versatility across vocals, instruments, podcasting, and studio recording applications.
Hand-assembled, tested, and tuned in California, the Mini K87 has earned a reputation as a go-to “do everything” studio microphone thanks to its transparent response, low self-noise, and ability to capture the true character of a source with depth and accuracy.
Unlike overly hyped condenser microphones that exaggerate high frequencies or add harshness, the Mini K87 is intentionally voiced for transparency and balance. Its carefully tuned K67/K87-style capsule delivers a natural frequency response with full lows, articulate mids, and detailed highs that remain smooth and controlled.
The result is a microphone that sits naturally in a mix and responds exceptionally well to EQ and processing when needed.
The Mini K87 excels on a wide range of recording applications, making it an ideal centerpiece for home studios, professional recording setups, and voiceover environments.
Popular uses include:
Lead vocals
Voiceover and podcasting
Acoustic guitar
Drum overheads
Piano
Strings
Electric guitar cabinets
Room microphones
Because of its neutral voicing, the Mini K87 adapts easily to different sources without imposing excessive coloration or harshness.
Each Mini K87 microphone is assembled and tuned in Roswell Pro Audio’s California workshop using carefully selected components chosen for sonic performance and consistency. Every microphone undergoes extensive burn-in, quality control, and audio testing before shipping.
The microphone features a solid steel body, audiophile-grade components, and Roswell’s transformerless circuit design for low distortion, low noise, and reliable long-term performance.
