Audio-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).

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

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

According to the manufacturer:
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.

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