AT4033A

The AT4033a is a cardioid studio condenser with a strong forward presence, a 40 Series design that has been a fixture on vocals and acoustic sources for decades. Bluegrass players and voice actors reach for it for the same reason: it puts the source right at the front of the mix without added processing.

Low-noise, symmetrical, transformerless circuitry gives it fast transient response and a clean output signal. The 2-micron vapor-deposited gold diaphragm goes through a five-step aging process so its characteristics stay put over years of use, and the precision-machined nickel-plated brass baffle keeps the element stable and sensitive.

The 80 Hz high-pass filter switches between flat response and a low-end roll-off that trims ambient noise and softens plosive energy on close-miked vocals. A 10 dB pad extends maximum input to 155 dB SPL. Frequency response runs 30-20,000 Hz with a 128 dB dynamic range and 100 ohm impedance.

A floating-construction capsule assembly isolates the element from noise and vibration, and the symmetrical open housing reduces internal reflections that would otherwise color the sound.

Use it for lead vocals, voiceover, acoustic guitar, upright bass, mandolin, and room capture. It requires 48V phantom power and includes the AT8449a shock mount, a dust cover, and a protective carrying case.
