Violet Design AMETHYST-STAN-COMBO

The Amethyst Standard uses single diaphragm capsule and is designed for what we know as the modern sound - with airy highs, extended vocal presence, accented low end response and unidirectional cardioid pattern. Large size diaphragms are made of the highest quality 6-micron Mylar film. Using Violet Design technology, the diaphragms are tensioned and adjusted on precisely made brass backplates. The diaphragms are sputtered with the Violet Design special formula of gold mixture. It gives them faster impulse transient response without sound coloration, low frequency reduction, and adds possibility to handle louder sound pressure levels. At the end of the manufacturing process each capsule is carefully checked for all parameters and measured in an anechoic chamber for optimum of performance. The microphones headgrill is made as acoustic filter of multilayer brass mesh that reduces plosive sounds, breath, pop and wind noises, minimizes internal resonance effects, but keeps high frequencies and sound transparency unaffected. Rugged microphone construction and two internal shockmounts, separately for the capsule and for the electronics, effectively reduces stand rumble, outside infrasonic interference and mechanical shocks.

The Amethyst microphone is designed for the recording studio all-around needs, capable of capturing vocals, piano, guitars, drums, percussion, strings, wind and other instruments. The microphones can be successfully used in professional sound reinforcement systems, in broadcast and TV studios, in movie and video industry, project studios and home recording, and many other applications. The internal solid state preamplifier of the microphone is based on class-A fully discrete transformerless electronics circuit, built using only the best quality selected components. The circuit is designed under the highest audio standards and provides linear audio frequency range, high dynamics, low self-noise, and very low audio distortion of all types.
