The Audio Technica 4033/CL:

This impressive side-address Cardioid condenser microphone broke the barrier in its class when it was released. This new version of the critically-acclaimed AT4033, the AT4033/CL, is a studio classic and favorite that boasts low-noise, symmetrical, transformerless circuitry that results in exceptional transient response and clean output signals. From drum overheads to vocals, from guitar cabinets, broadcasting, and woodwind sections, the AT4033/CL is certainly a versatile microphone. A solid presence defines the sonic signature of this 40 Series pro-audio microphone. The AT4033/CLs 80Hz high-pass filter seamlessly switches between flat frequency response and a low-end roll-off that virtually eliminates ambient noise and popping (aka "plosives") normally present in close-proximity vocals and dialogue.

  1. The 2-micron-thick, vapor-deposited gold diaphragm undergoes a five-step aging process so the optimum characteristics achieved remain constant over years of use.
  2. Precision-machined, nickel-plated brass, acoustic element baffle provides enhanced element stability and optimal sensitivity.
  3. Floating-construction capsule assembly provides isolation from noise and vibration.
  4. Open acoustical environment of the symmetrical housing assembly minimizes unwanted internal reflections.
  5. Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of highspeed transients.
  6. State-of-the art surface-mount electronics ensure compliance with A-Ts stringent consistency and reliability standards.
