The Audix A131 Large Diaphragm Condenser Microphone delivers detailed, natural sound for professional recording, podcasting, vocals, and live performances. Featuring a precision-engineered 33 mm condenser capsule, cardioid polar pattern, and low-noise circuitry, the A131 captures vocals and acoustic instruments with clarity while minimizing unwanted background noise.
Designed for versatility, the Audix A131 is an excellent choice for recording studios, podcast production, choir performances, piano, acoustic guitar, and drum overhead applications. Its compact design and rugged machined aluminum construction make it equally suitable for permanent studio installations and demanding live sound environments.
At the heart of the A131 is a 33 mm fixed-charge condenser capsule with a 29 mm gold-sputtered diaphragm, engineered to provide a smooth, natural frequency response from 40 Hz to 20 kHz. The microphone's cardioid pickup pattern focuses on sound directly in front of the capsule while reducing off-axis noise and room reflections.
Unlike many large diaphragm condenser microphones that require bulky external shock mounts, the A131 incorporates a proprietary internal shock-mounting system to reduce handling noise and mechanical vibrations.
A double-woven steel mesh grille with acoustic foam provides additional protection against vocal plosives, making the microphone particularly useful for podcasting, voiceover work, and vocal recording.
With its low self-noise, high maximum SPL handling, and durable construction, the Audix A131 offers professional recording performance in a compact, road-ready design.

Professional Vocal and Podcast Recording
The Audix A131 is designed to capture vocal performances with clarity, detail, and a natural tonal balance.
Its large diaphragm condenser capsule reproduces subtle vocal characteristics, making it suitable for lead vocals, spoken-word recordings, podcasting, and voiceover production.
The cardioid pickup pattern helps reduce unwanted sound from the sides and rear of the microphone, while the integrated grille and acoustic foam help control plosive sounds.
The microphone's low self-noise is especially beneficial when recording quieter voices or detailed acoustic performances.
Versatile Instrument Recording
Beyond vocals, the A131 performs well across a wide variety of acoustic instruments and musical applications.
Its extended frequency response and ability to handle sound pressure levels up to 140 dB make it suitable for recording piano, acoustic guitar, percussion, and drum overheads.
The microphone can also be used for choir recording and other applications where accurate reproduction of multiple sound sources is important.
Built-In Shock Isolation
The Audix A131 features a proprietary internal shock-mounting system that isolates the microphone capsule from mechanical vibrations.
This design helps reduce unwanted noise caused by microphone stands, handling, and nearby movement.
By incorporating shock isolation directly into the microphone, the A131 eliminates the need for a bulky external shock mount in many installations.
