The Audio Technica AT-4033/CL is a large diaphragm, side address cardioid condenser microphone. Designed for professional and project recording, the AT-4033/CL delivers high audio signal reproduction with very low self-noise resulting in a strong, up-front audio signal. The cardioid pick-up pattern effectively minimizes audio at the off-axis sections of the microphone, eliminating noise caused by room ambiance, monitors etc. The microphone's output stage features transformerless circuitry which virtually eliminates low-frequency distortion and effectively maintains the integrity of transient audio signal. The microphone utilizes +48 volt phantom power and features 10dB pad and 80Hz high-pass filter switches for added control over dynamic range and low-frequency noise.
