The Roswell Aztec Tube Microphone is Roswell's flagship boutique tube mic that offers a super musical character and fullness, making the Aztec stunning for vocals. This version features a classic cream finish.
The Roswell Aztec Tube Microphone 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. Also Available in Black!
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.
Roswell Aztec Tube Microphone Features
- Our RK-251 capsule, single-triode circuit, and custom European-made transformer capture a timeless sound: full low end, honest midrange, and airy, intimate highs.
- Independent pad and filter switches, and polar pattern control provide comprehensive versatility.
- The 9-position pattern control, located on the power supply, provides repeatable, discrete selection of polar pattern.
- Both the Aztec microphone and its power supply incorporate premium, rare, and "unobtanium" components. These parts elevate the mic's sound, drawing comparisons to well-preserved, revered vintage microphones.
- The included Gotham GAC7/Neutrik XLR cable ensures maximum signal fidelity and minimum voltage loss. The included AudioQuest IEC power cord ensures a robust connection to mains AC supplies.
- The Aztec power supply is fully regulated, ensuring consistent sound even when subjected to varying AC supply levels.
