Audix A133 - Large Diaphragm Condenser Microphone for Studio and Live Performance
The Audix A133 redefines the standard for modern condenser microphones, combining precision American-engineered construction with crystal-clear sound quality. Designed to be a workhorse in both professional recording studios and demanding live environments, the A133 features a large-diaphragm 33mm capsule that captures every nuance with astonishing fidelity.
Unlike traditional studio microphones, which are often fragile and bulky, the A133 features a compact and robust machined aluminum chassis. At its heart is a fixed-load capsule with a 3.4-micron gold-sprayed diaphragm, ensuring a wide and natural frequency response. Thanks to its exceptionally well-controlled cardioid polar pattern, this microphone delivers a coherent and focused sound, effectively rejecting ambient noise and room reflections from the sides and rear.
One of the A133's most notable innovations is its patented internal capsule mounting system. This advanced design acts as an effective damper, isolating the capsule from mechanical vibrations and handling noise without the need for bulky external shock mounts or elastic supports. This not only makes it easier to place in tight spaces—such as on a drum kit or in front of an amplifier—but also provides a clean, professional aesthetic, ideal for podcasters and streamers who appear on camera.
Versatility is key to the A133. Equipped with -10 dB pads and a roll-off low-cut filter, this microphone is ready to handle high sound pressure levels or bass-heavy environments without distortion. Furthermore, its double-weave steel mesh grille, combined with ultra-thin acoustic foam, provides exceptional pop resistance, allowing for intimate and direct vocal recordings without the need for external pop filters.

Frequently Asked Questions
-
Does the Audix A133 need phantom power?
Yes, being a condenser microphone, it requires 48-52V phantom power to function properly.
-
Do I need to buy a separate shock mount?
No, the A133 features a highly effective internal shock-absorbing system that eliminates the need for external shock mounts. It mounts directly using the included microphone clip.
-
What are the microphone switches for?
The "Pad -10 dB" switch reduces sensitivity for recording very noisy sources without distortion. The "Roll-off" switch (bass filter) eliminates unwanted low frequencies, such as traffic noise or stage rumble.
-
Is it suitable for rooms without acoustic treatment?
Thanks to its well-defined cardioid pattern, the A133 excels at rejecting room noise, helping to achieve drier, cleaner recordings even in less-than-ideal environments.
Project description
Large-diaphragm studio condenser microphone with a cardioid polar pattern. Features a 33mm fixed-charge capsule with a 3.4-micron gold diaphragm. Frequency response is 40 Hz to 20 kHz, with an impedance of 150 ohms and a sensitivity of 23 mV/Pa @ 1 kHz. It incorporates an internal shock mount, a double-weave steel mesh grille, and acoustic foam. Selectable switches provide a -10 dB pad and a 150 Hz roll-off. Maximum SPL handling capacity is 150 dB (with the pad). Machined aluminum body. Requires P48 phantom power.
