Audio Technica AT 4033 ASM
The AT4033a/SM is a transformerless studio microphone
designed for use in the most demanding applications. Specifically,
the AT4033a/SM utilizes a gold-plated, “aged-diaphragm” capacitor
element with an internal baffle plate to increase the signal-to-noise
ratio of the microphone system. This, coupled with low-noise
transformerless electronics, makes this microphone ideal for the
most critical digital recordings.

Description
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
