Roswell Pro Audio Aztec - Boutique Tube Microphone

The Roswell Aztec is a boutique multi-pattern tube microphone built without compromise.

The Aztec results from several years' worth of R&D and component testing, during which every piece of the microphone and power supply was reviewed, revised, and improved. The result is a stunning microphone: intimate and rich, never harsh or brittle.

Testimonials

"I’m a microphone maniac. Most clones don’t do anything for me. The Roswell Aztec made my jaw drop. It has this modern pop-edge that differentiates an Elam 251 from a C12, without the annoying harshness of most modern microphones that strive to achieve this."

Christian Seitz
Producer (58M records sold)

"Holy ****, this mic sounds great!"

"This mic could pass for a $5000 model ... the attention to ALL the details is astounding."

Rob Tavaglione
Writer, MIX Magazine

"I tried Aztec alongside some mics that I had on hand ranging from $5000–$7000, and it absolutely held its own in sonics and depth -- and I do not say that lightly."

It's Not A Clone... It's Better

The Aztec does not pretend to be a copy of anyone else's microphone. We borrow liberally from proven designs, and we relentlessly upgrade everything we possibly can.

The Aztec uses a single triode circuit topology, with a selected 6072 tube. Noise filtering components within the mic are upgraded, using higher quality and higher value parts to reduce noise. Input and output capacitors, which pass the mic's audio signal, are ultra-premium parts selected by ear.

The original European power supplies were typically unregulated, which means tube voltage will drift as the mains AC voltage changes. Rather than subject your recordings to unexpected sonic changes just because the HVAC or refrigerator cycles on or off, we provide a fully regulated power supply that delivers precisely the correct filament and plate voltages, regardless of mains AC changes.

Versatility, By Design

The Aztec provides nine discrete polar patterns, each of which can be precisely recalled via the rotary potentiometer on the power supply.

A switch on the microphone engages a 10dB attenuation control, which allows the mic to be used for louder sources without internal clipping.

A second switch on the mic engages a high-pass filter, which rolls off the mic's low frequencies (-3dB @ 140 Hz); use this to control proximity effect with close mic placements.

Cosmetic Options

The Aztec microphone has a satin black body, or in a colour we call "Vintage Cream." The VC mic bodies tend to have minor imperfections, such as a dot or a bump in the finish. The grille is chrome.

The power supply for black microphones is silver. For cream-coloured microphones, the power supply matches the microphone colour.
