The microphone uses an optimized transformerless circuit, which provides a clean signal path. The microphone’s circuit boards are manufactured and populated in the United States, using quality components sourced from around the world, including low-noise NOS transistors and imported European capacitors.

Roswell Aurora Condenser Microphone Features:

» 34mm, 3-micron large-diaphragm condenser capsule
» Transformerless circuit
» Switchable pad and pattern
» Natural, unhyped frequency response
» Fast transient response
» Enhanced articulation
» Solid, high-quality construction
» High sensitivity
» Low self-noise and distortion
» Modern performance with vintage tone
» Extensive Quality Control testing

The transistors in the Aurora are all NOS parts, no longer made but ideal for this circuit. The JFET is selected for low input capacitance, then manually biased in our shop to maximize signal level without distortion. Every resistor in both the audio and DC power circuits is a low-noise metal film type with 1% tolerance. Special care was taken to select signal-path capacitors for the best sound. Even the non-signal-path parts are upgraded, non-microphonic NP0 types.

Two switches located on the front of the microphone provide pattern control (Cardioid/Omni) and pad (-10dB). Each Aurora is assembled in California, manually “burned in,” and extensively tested after manufacturing to ensure the best possible performance. Each Aurora includes an elastic shockmount, a vinyl storage pouch, and a compact flight case.

“The idea for Roswell Pro Audio came out of 5+ years worth of experience modifying commercial microphones. My first business is called Microphone-Parts.com; it sells upgrade parts for inexpensive mics, as well as all-inclusive DIY kits that are essentially $1000 microphones sold in $300 kit form,” reveals Matthew McGlynn, owner of Roswell. “That experience has allowed me to understand what really makes a difference in a microphone, on a component level.”

“For the Roswell line,” McGlynn continues, “we are applying all this expertise to create a line of microphones that I believe fill a gap in the current commercial market. Take the Mini K47 as an example: it’s the only mic in its price range with a true 34mm K47 style capsule. It doesn’t sound like anything else in its range, and it stands up to mics costing a lot more. It is more versatile than competitive offerings, and it has higher output and lower noise than many of them.”

This concept sums up the Roswell philosophy and has extended to the new Aurora. Even though it’s not inexpensive, McGlynn and company are looking to add American-built quality to microphone manufacturing, and to prove that great products can come from careful part selection, savvy design and quality control.

The Roswell Aurora is available now for $749.
