Audio-Technica AT4050ST Stereo Condenser Microphone

Stereo Condenser Microphone for Professional Studio Recording

The Audio-Technica AT4050ST is a side-address stereo condenser microphone designed for high-end studio recording, broadcast production, and critical audio capture. It houses two independent condenser elements within a single body, allowing engineers to record accurate stereo sound with excellent detail and spatial definition. This microphone is built for professionals who need flexible stereo recording options while maintaining consistent tonal accuracy across the full frequency range.

Dual Capsule Design for Precise Stereo Imaging

Inside the AT4050ST are independent cardioid and figure-eight condenser elements that work together to maintain precise polar pattern control. This dual-capsule design allows the microphone to deliver stable stereo imaging while minimizing phase issues. The configuration ensures consistent response across the frequency spectrum, making it well suited for orchestral recording, acoustic instruments, drum overheads, and ensemble capture.

Selectable Left Right or Mid Side Output Options

The microphone offers the ability to output either a traditional left-right stereo signal or a discrete mid-side signal. This flexibility allows engineers to choose their preferred stereo technique during recording or post-production. Mid-side capability is especially useful for adjusting stereo width after tracking, making the AT4050ST a versatile tool in both studio and broadcast workflows.

Transformerless Circuitry for Clean Transient Response

The AT4050ST uses internal transformerless circuitry designed to reduce low-frequency distortion and improve transient accuracy. This circuit design supports fast, clean response to dynamic sound sources while maintaining excellent detail in complex passages. The result is clear, natural audio reproduction that remains controlled even during demanding recordings.

Gold Deposited Diaphragms for Long Term Stability

Each diaphragm is vapor-deposited with a thin layer of gold and undergoes a multi-stage aging process to ensure long-term consistency and reliability. This careful manufacturing approach helps maintain stable performance over years of use, supporting dependable results in professional recording environments.

Switchable Filters and Pad for Recording Flexibility

An onboard 80 Hz high-pass filter helps reduce low-frequency rumble, hum, and mechanical noise, while a switchable 10 dB pad provides added headroom when recording loud sound sources. These controls allow the microphone to adapt easily to different recording scenarios without external processing.

Complete Accessory Package for Studio Use

The AT4050ST includes a custom shock mount to reduce vibration, a long multi-conductor XLR cable, a dust cover, and a protective carrying case. The microphone is also certified by the METAlliance, confirming its suitability for professional studio and broadcast environments.
