Audix A231-USM Large-Diaphragm Cardioid Condenser Microphone

Professional Studio Microphone Bundle For Vocals Instruments And Podcasts

The Audix A231-USM is a professional large-diaphragm condenser microphone bundle designed for studio recording, podcast production, voiceover work, and acoustic instrument capture. This package pairs the A231 condenser microphone with a Rycote USM shockmount and pop filter, giving users a ready-to-record solution that delivers detailed sound, controlled isolation, and consistent performance across recording environments.

Large Diaphragm Condenser Capsule With Focused Cardioid Pickup

The A231 features an externally biased 33 mm condenser capsule with a gold-sputtered diaphragm engineered for clarity, warmth, and accuracy. The cardioid polar pattern focuses on the sound source while reducing room reflections and off-axis noise, making it ideal for vocal recording, acoustic instruments, and spoken-word content. The oversized diaphragm provides increased sensitivity and captures subtle detail without sounding harsh or exaggerated.

Ultra Low Noise Circuitry With Active Signal Protection

Designed for critical studio use, the A231 incorporates ultra-low-noise preamp circuitry that preserves dynamic range and minimizes self-noise. Active driven shielding protects the signal path from capacitive coupling and external interference, ensuring clean audio capture even in complex studio setups. This design supports professional recording workflows where signal purity and consistency are required.

Integrated Shock Isolation And Plosive Control

The microphone’s internal shockmount reduces mechanical vibrations and handling noise without the need for bulky external suspension systems. A double-woven steel grille combined with ultra-thin acoustic foam helps reduce plosives and sibilance, making the A231 well suited for close-miked vocals and podcast recording. These built-in elements streamline setup while maintaining reliable performance.

Rycote Shockmount And Pop Filter For Additional Isolation

This bundle includes a Rycote USM shockmount and pop filter, providing an added layer of vibration isolation and plosive control. The Rycote suspension system helps decouple the microphone from stands or booms, while the included pop filter further minimizes breath noise during vocal recording. Together, these accessories help maintain consistent sound quality during long recording sessions.

Durable Construction And Studio Ready Accessories

The A231 is housed in a precision-machined aluminum body built for daily studio use. It operates on standard 48V phantom power via a balanced XLR output and includes a snap-on microphone clip and zippered pouch for storage and transport. Designed and assembled in the USA, the A231-USM bundle is built for reliability in professional recording environments.
