Aston Stealth is four microphones in one lightweight package
Aston Stealth is designed to be the Swiss-army knife microphone, with four modes and working with Phantom Power or not.
One of the most intuitive features of the new Aston Stealth is the fact that it works in both passive and active modes, meaning it automatically senses whether there is a 48v Phantom Power signal, if there is, it enabled active mode. Active mode uses a built-in Class A mic Preamp which greatly boosts the signal of the microphone. Aston also boasts that the new microphone’s build quality is “near-indestructible”.
The Aston Stealth features four independent modes, which were developed in partnership with more than 90 top audio engineers, producers and artists. The panel participated in blind listening tests to nail down the four best sonic signatures.
Aston Stealth features two modes tailored to vocals, a Guitar setting and a “Dark” setting which is supposed to emulate the classic vintage sound of ribbon microphones. Often microphones with various curve settings are applying EQ to the signal, this is not the case with the Aston Stealth. The settings apply various contour networks as opposed to traditional filter circuitry which can often add unwanted phase and harmonic distortion.
Who is the Aston Stealth microphone designed for? 
The Stealth employs a cardioid polar pattern, and is capable of capturing frequencies between 20Hz and 20kHz. The microphone is perfect for both stage and studio use, the auto sensing and varying modes make it indispensable for gear dry-hire companies and touring audio engineers, as you never know what situation you may have to deal with and what sort of gear you may need to plug into. It weighs in at under 700g (which is TINY for a condenser microphone), so it won’t add much weight to the rig at all!
