Roswell Mini K47 Condenser Microphone

The Roswell Mini K47 is very solid 'All Around' mic. It performs very well on virtually all sound sources, has a real life to it, and is well built. A true bang for the buck mic, that is quality and won't break the bank. How about a matched pair for stereo recordings!

Roswell Mini K47 Condenser Microphone Details

The Mini K47 is the most affordable K47-based condenser microphone on the market, capturing the tone of a vintage microphone, with modern performance specifications.. The "K47" refers to the capsule design. The capsule in this microphone is modeled after the one in the Neumann's U47. It provides a full, balanced tone without any harshness or hype in the upper frequencies. It will record less sibilance and fewer mouth sounds on your next vocal track. It will add weight and body to high strings. It will reduce the jangle in strummed acoustic tracks.

For this microphone, we chose a very clean and transparent circuit design. It lets the sound of the capsule pass through without alteration. Self-noise and distortion performance are on par with microphones costing significantly more. We've applied the best tricks we've learned from modifying and upgrading other companies' products.

To ensure that every Mini K47 microphone delivers superior performance out of the box, Roswell tests them extensively prior to shipping: for polarity, noise, frequency response, and sensitivity. Roswell listens to every microphone before it leaves their facility.

The Mini K47 ships with a swivel mount, shock mount and padded storage pouch.

The Mini K47 is built into a body used by several other manufacturers. But it differs extensively from those lookalike microphones, in its components, its performance, and its sound. The most significant difference is in the capsule. While competing models use either a small-diaphragm capsule or an undersized 32mm K67 type, the Mini K47 -- as its name states -- uses a true 34mm K47 type capsule, modeled after the capsule in the most famous microphone of all time. We selected this capsule because it delivers a sound that no K67-based microphone can ever achieve: beautiful midrange detail with a neutral, rather than a hyped, top end.

Most of the condenser microphones under $800 use the 2SK170 JFET, a low-cost, general purpose amplifier that can sound good when configured properly. But it usually used in circuits where its very high input capacitance (Ciss, 30pF) acts like a hardwired pad: it reduces the mic's sensitivity, which effectively raises the mic's noise floor. We prefer a JFET with a much lower input capacitance. We bias each one individually within the microphone's circuit, to ensure the highest possible gain without distortion. The input coupling cap is the first component most aftermarket "modders" would change, because so many condenser mics use a low-grade ceramic or generic polyester box film type in this critical position. For the Mini K47, we use a polystyrene part. Styrene capacitors are generally considered to be the most neutrally voiced, cleanest sounding capacitors.

The main signal capacitors in this circuit are polypropylene film types, imported from Germany. This combination of components delivers a sonic profile that is much more musical and balanced than anything in its price category.

What We Think

The Mini K47 is a surprising first offering from Roswell. It is quite musical, with an overall smooth character and nice rich elevated mid range. It is clearly well suited for vocals (male or female), and does a solid job at capturing the detail of the performance. Yet furthermore, it has a lush tone to compliment the chest resonance of the performer. More surprising still is that the mic does not pigeonhole itself into a one trick pony. It equally performs as well on electric guitar cab (clean and distorted), pairs well with brighter acoustics, holds its own on drums and drum overheads, and more pleasing to me - is the performance on mandolin. Mandolin can be an interesting and challenging instrument to record, but my mandolin seemed to be quite fond of the Mini K47. As well as I. All in all, a solid mic at a great point that won't kill your wallet. I'm curious, and interested in what else Roswell will have to offer.
