The classic edition of the legendary AT4033 microphone, the side-address AT4033/CL offers low-noise, symmetrical, transformerless circuitry that results in exceptional transient response and clean output signals. A studio classic and bluegrass favorite, the AT4033/CL 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 AT4033/CL’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.

Case Style :
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.
