Audix A231 Large-Diaphragm Cardioid Condenser Microphone with Shockmount and Pop Filter

Truly Transparent Studio Recording

Designed for professional studio recordings and podcasts, the Audix A231 with Shockmount and Pop Filter is a premium large-diaphragm condenser microphone engineered for discerning users who demand exceptional detail and warmth. Its externally biased “true condenser” capsule and low-noise circuitry deliver pristine audio, capturing the nuances of the human voice and the rich overtones of acoustic instruments with remarkable clarity. The A231’s exceptionally consistent cardioid polar pattern focuses on the performance while providing smooth off-axis rejection, ensuring a clean and natural sound. This package includes a Rycote USM shockmount and pop filter, effectively isolating the microphone from unwanted vibrations and plosive sounds. The A231 is proudly designed, machined, assembled, and tested by Audix in Wilsonville, Oregon.

Precision-Engineered Capsule

• At the heart of the A231 is a 33mm condenser capsule, featuring a precision-tensioned diaphragm made from a specially formulated, heat-treated film.
• Gold deposition extends to the far edges of the diaphragm, increasing the effective surface area by 25% compared to standard large-diaphragm microphones.
• The result is enhanced sensitivity and detail, making it ideal for critical studio applications.

Active Driven Shield for Signal Purity

• An active driven shield protects the signal path from the capsule to the preamp, preventing interference from capacitive coupling and eliminating unwanted signal leakage.
• This ensures the microphone maintains an ultra-clean, noise-free signal.

Optimized Grille and Internal Shockmount

• The A231’s double-woven steel-mesh grille is lined with an ultrathin acoustic foam, providing superior resistance to vocal plosives—perfect for podcasting and vocal recording.
• Additionally, the internal shockmount isolates the capsule from mechanical vibrations and handling noise, preserving the integrity of every recording.
