Large diaphragm Microphone

AT4033a

The latest edition of the legendary AT4033 microphone, the side-address AT4033a offers low-noise, symmetrical, transformerless circuitry that results in exceptional transient response and clean output signals. A studio classic and bluegrass favorite, the AT4033 cardioid studio condenser is the microphone that broke the US$1000-barrier in its class. A strong up-front presence characterizes the sonic signature of this 40 Series pro-audio classic. The AT4033a’s 80Hz high-pass filter easily switches between flat frequency response and a low-end roll-off that diminishes ambient noise and popping with closely-miked vocals. Includes the AT8449a shock mount for superior isolation.

*The AT4033a is the same microphone as the AT4033/CL. The AT4033a comes equipped with the AT8449a shock mount whereas the AT4033/CL included the AT8449 shock mount.*

Features

Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of high-speed transients

Precision-machined, nickel-plated brass, acoustic element baffle provides enhanced element stability and optimal sensitivity

The 2-micron-thick, vapor-deposited gold diaphragm undergoes a five-step aging process so that the optimum characteristics achieved remain constant over years of use

Floating-construction capsule assembly provides isolation from noise and vibration

Open acoustical environment of the symmetrical housing assembly minimizes unwanted internal reflections

State-of-the-art surface-mount electronics ensure compliance with A-T's stringent consistency and reliability standards

Custom shock mount provides superior isolation
