Description

The Audio‑Technica AT4033a is a professional‑grade studio condenser microphone designed for demanding recording applications — vocals, acoustic instruments, strings, woodwinds, and detailed studio work. Its precision‑machined 2‑micron vapor‑deposited gold diaphragm and transformerless low‑noise circuitry deliver exceptional transient response, clarity, and a wide dynamic range.

With a cardioid polar pattern, the AT4033a captures sound from the front while minimizing unwanted ambient noise and off‑axis sound — making it ideal for controlled studio environments. A switchable 80 Hz high‑pass filter and –10 dB pad let you tame low‑end rumble or manage loud sound sources without distortion. Housed in a robust metal body with an included shock‑mount, the microphone offers reliable isolation from handling noise and stand‑borne vibration.
