CardioidAudio-Technica AT4033/CL

Cardioid Condenser Microphone

The AT4033/CL is a side-address electret condenser microphone with a transformerless FET amplifier circuit.

A switch on the mic body provides access to a high-pass filter (80Hz).
AT4033/CL Cutaway

The small-diaphragm electret capsule uses a 2-micron diaphragm measuring 11.5mm in diameter.

Audio-Technica

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.

  • 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

The Audio-Technica AT4033/CL is also known as: AT4033-CL, AT4033CL, AT4033.
