Audix A133 Large-Diaphragm Cardioid Condenser Microphone

Large Diaphragm Condenser Microphone For Studio And Live Use

The Audix A133 is a professional large-diaphragm cardioid condenser microphone designed for accurate capture of vocals, acoustic instruments, and amplified sources in both studio and live sound environments. Built with integrated noise control and onboard filtering, the A133 gives engineers and performers a reliable recording tool that delivers detailed sound without requiring external shockmounts or pop filters.

Cardioid Pickup Pattern For Focused Sound Capture

The cardioid polar pattern provides strong rejection of off-axis sound, helping reduce room reflections, stage bleed, and background noise. This focused pickup makes the A133 well suited for vocals, choir, piano, acoustic guitar, drum overheads, and podcast recording where clarity and separation are critical.

Gold Sputtered Electret Capsule With Wide Frequency Response

At the core of the A133 is a fixed-charge electret condenser capsule with a 1.1-inch gold-sputtered diaphragm. This large diaphragm design delivers a balanced frequency response with excellent transient detail, smooth high frequencies, and controlled low-end reproduction. The capsule accurately captures subtle dynamics while maintaining consistent phase response.

Onboard Pad And High Pass Filter For Flexible Recording

Two integrated switches provide practical control at the microphone. The selectable -10 dB pad helps prevent distortion when recording loud sound sources such as drums or guitar cabinets. The 150 Hz high-pass filter reduces low-frequency buildup, making it easier to manage proximity effect and excessive bass during vocal or instrument recording.

Internal Shock Isolation And Pop Resistant Design

An internal shockmount system isolates the capsule from handling noise and mechanical vibrations, eliminating the need for an external shockmount. The double-layer steel grille combined with ultra-thin acoustic foam minimizes plosives and breath noise, making the A133 ideal for vocals, spoken word, and podcast applications.

Durable Aluminum Construction For Studio And Stage

The precision-machined aluminum body provides long-term durability for daily studio use and touring environments. Its compact form factor fits easily on standard microphone stands and boom arms. Designed and built in the USA, the A133 is engineered for consistent performance under demanding conditions.

Standard Phantom Power With Balanced XLR Output

The A133 operates on standard 48V phantom power and connects via a balanced XLR 3-pin output. For optimal performance, it pairs well with high-quality microphone preamps and professional XLR cables, delivering clean and stable signal transmission in studio and live sound systems.
