“Clean, Crisp and Accurate”

Transparent uppers/mids and rich low-end qualities are combined with advanced acoustic engineering for extensive performance abilities and a clean, crisp and accurate sound reprodction, even at high SPL's.

“outstanding performance”

Gold vapourized, aged dual-diaphragms give consistent outstanding performance, and precise polar pattern definition across the full dynamic range.

“A versatile studio or live mic”

The AT4050 is equally at home in the studio as it is in live environments. Ideal for studio vocals, it is also perfect on guitar amps, drum overheads, piano, strings and more, making it a versatile studio or live mic.

versatile sound

The AT4050 has omni, cardioid and figure of eight polar patterns, offering versatile sound options.

dual-diaphragm capsule

Dual-diaphragm capsule maintains precise polar pattern definition across the full frequency range.

transformerless circuitry

The transformerless circuitry virtually eliminates low-frequency and provicdes superior correlation of high-speed transients.


An advanced-design custom shock mount provides superior isolation attenuating noise, shock and vibration.
