Overview

The AT4053b features a hypercardioid polar pattern that reduces pickup of sounds from the sides and rear, improving isolation of the desired sound source. Its direct-coupled, balanced output ensures a clean signal even under high-output conditions, while the transformerless circuitry virtually eliminates low-frequency distortion. This microphone is RoHS-compliant, adhering to the EU directive on the reduction of hazardous substances, making it environmentally friendly as well. The AT4053b consists of two modular subassemblies: the AT4900b-48 body and the AT4053b-EL hypercardioid head capsule, both of which are available separately. Additional interchangeable capsules in omnidirectional (AT4049b-EL) and cardioid (AT4051b-EL) are also available.

Features

• Hypercardioid Polar Pattern: Reduces pickup of sounds from the sides and rear, providing excellent isolation of the sound source.
