Think of Stealth as four professional microphones in one. Each setting has been voiced by a panel of more than 90 top flight audio engineers and producers on the Aston 33 panel through a series of double-blind listening tests, beating not only every mic in its class, but some far more expensive ‘industry standard’ mics.
There are 2 vocal settings, optimised for different vocal tones, a guitar setting which is equally suited to Spanish guitar, Electric guitar cab and steel string acoustic, and a dark, vintage setting, reminiscent of classic ribbon mics.
Mics which apply ‘flattering’ - but destructive - pre EQ make professional post-processing almost impossible. Stealth, however, provides a choice of four pure, high quality signal paths. The voice settings are not EQ filters, they are contour networks, meaning the bulk of the signal does not pass through any sort of filter circuitry. The whole signal is slightly attenuated, with some frequencies being added back in at a higher level. This results in much lower phase distortion than conventional filter designs.
Active & Passive modes with 48V Autodetect function
Stealth works with or without 48V phantom power. In passive mode (unpowered) the active circuit is completely bypassed and Stealth operates with the simplest possible signal chain to give a beautifully clean sound.
A unique (world’s first!) built-in Autodetect function senses the presence of 48V phantom power and will automatically switch the mic to active mode to utilise the onboard class A mic Pre.
In passive mode Stealth behaves just like a stage dynamic mic and will handle pretty much any levels you can throw at it; screaming vocals, maxxed-out guitar cabs, even drums.
Engage active mode and there’s a massive 50dB gain lift giving you all the headroom and sensitivity of a studio condenser; back off just a little for smooth vocals, spoken word and acoustic instruments, or get close-up and personal for breathy intimacy and crystalline detail.
If you want to get loud and gnarly… back it off baby!!! You should leave the same sort of distance for loud source mic placement as you would a condenser mic without a pad… about 30 cm in most cases.
Built-in Class A Mic Preamp
When in active mode Stealth features a high quality built-in Class A Mic Pre, dispensing with the need for an expensive external gain lifting device.
Stealth features a fully balanced signal path from capsule to output, yielding a superior reduction of ‘Common Mode’ noise compared with single-ended (unbalanced) designs.
Unique Sorbothane internal shock mount
Aston Stealth includes a proprietary internal shock mount design with the capsule suspended in mid-air, completely isolated from the mic chassis, and supported at 3 points by Sorbothane polymer hemi-spheres.
Sorbothane is a synthetic viscoelastic urethane polymer used as a vibration damper and acoustic shield used in computing, hi-fi and many industrial applications.
Exceptional side rejection
Stealth’s acoustically tuned headstock provides a highly focused cardioid polar pattern with enhanced off-axis rejection.
Excellent rejection of electromagnetic hum
Stealth’s capsule is fully enclosed in a Stainless Steel Faraday cage - an enclosure used to block electromagnetic fields (named after the English scientist Michael Faraday, who invented them in 1836)
A Faraday cage operates because an external electrical field causes the electric charges within the cage's conducting material to be distributed such that they cancel the field's effect in the cage's interior. This phenomenon is used to protect sensitive electronic equipment from external radio frequency interference (RFI).
Of course, if you ever get stuck for a teabag it can double up on duty for a good brew!
