User manual VIOLET DESIGN AMETHYST DESCRIPTION

[. . . ] They possess very fast impulse transient response without sound coloration or low frequency reduction, as well as the ability to handle louder sound pressure levels. [. . . ] The internal phantom powered preamplifier is a fully discrete Class 'A' transformerless circuit which provides high output, flat audio response and ulta-low distortion and noise. The Amethyst Vintage has a grey/blue body and uses a dual large-diaphragm, center terminated dual back plate capsule which provides a classical, wide-spectrum, vintage microphone sound. Both models have a unidirectional cardioid polar pattern with minimal proximity effect and are linear over the wide frontal incidence angle. The Amethyst Standard is particularly recommended for percussion and stringed instruments. For vocal applications The Amethyst Standard is more oriented for a male voice and The Amethyst Vintage for a female voice. Use them up close, within 2" to 4" to get best results. [. . . ] The internal amplifier and capsule are hard to overload and are well suited for close miking of vocals.
