Audio-Technica AT4050ST Stereo Condenser Microphone Broadcast Recording

The Audio-Technica AT4050ST Stereo Condenser Microphone is a professional-grade microphone engineered for expert recording, broadcast, and sound reinforcement. Offering the realism of a live sound field, this side-address condenser microphone features cardioid and figure-of-eight elements configured in a unique Mid-Side arrangement. This versatility allows sound recordists to select between a left-right stereo output or discrete Mid-Side signals for post-production manipulation, providing unprecedented flexibility for any recording scenario.

Designed with dual-diaphragm capsules, the AT4050ST maintains precise polar pattern definition across the full frequency range. The microphone’s transformerless circuitry virtually eliminates low-frequency distortion, ensuring superior correlation of high-speed transients. With state-of-the-art design and manufacturing techniques, this microphone meets and exceeds Audio-Technica's stringent consistency and reliability standards.

The AT4050ST is METAlliance certified, meaning it adheres to the highest standards of quality and performance in music engineering and technology. It features an innovative 80 Hz high-pass filter switch and a 10 dB pad switch, making it adaptable for various recording environments. Its symmetrical housing assembly minimizes internal reflections, enhancing the open acoustical environment. A custom shock mount is included to provide superior isolation, ensuring pristine recording quality.
