AT4053b Hypercardioid Condenser Microphone

This versatile studio performer may be used with confidence in a wide variety of professional miking applications. Featuring direct-coupled balanced outputs for clean signals in high-output conditions, the microphone is totally free of the distortion associated with conventional transformer-coupled outputs. And its fast response to transients contributes to the open, transparent reproduction of even the most difficult-to-capture instruments. The microphone is fully RoHS-compliant – free from all substances specified in the EU directive on the reduction of hazardous substances (RoHS).

The AT4053b consists of two modular subassemblies: an AT4900b-48 body and an AT4053b-EL hypercardioid head capsule (both available separately). Additional interchangeable capsules are available in omnidirectional (AT4049b-EL) and cardioid (AT4051b-EL).

Specially engineered to meet the most critical acoustic requirements of professional recording, broadcast and sound reinforcement

Hypercardioid polar pattern reduces pickup of sounds from the sides and rear, improving isolation of desired sound source

Direct-coupled, balanced output results in a clean signal even under high-output conditions

Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of high-speed transients

Switchable 80 Hz hi-pass filter and 10 dB pad

Rugged turned-brass microphone housing for enduring dependability

State-of-the-art design and manufacturing techniques ensure compliance with A-T’s stringent consistency and reliability standards

RoHS-compliant – free from all substances specified in the EU directive on the reduction of hazardous substances (RoHS)
