Audio-Technica AT4051B Cardioid Condenser Microphone

The AT4051b is an externally polarized (DC bias) condenser microphone with a cardioid polar pattern. It is designed to meet the most critical acoustic requirements of professional recording, broadcast and sound reinforcement.

The AT4051b consists of two modular subassemblies: an AT4900b-48 body and an AT4051b-EL head capsule (both available separately). Additional interchangeable capsules with omnidirectional (AT4049b-EL) and hypercardioid (AT4053b-EL) pickup patterns are available, which can be ordered separately. The microphone requires 48V phantom power for operation. The cardioid polar pattern of the microphone is more sensitive to sound originating directly in front of the element, making it useful for controlling feedback and reducing pickup of unwanted sounds. The output of the microphone is a 3-pin XLRM-type connector. The microphone is equipped with a switchable 10 dB pad and a switch that permits choice of flat response or low-frequency roll-off (via integral 80 Hz high-pass filter).

The microphone is enclosed in a rugged housing. The included AT8405a stand clamp permits mounting on any microphone stand with 5/8"-27 threads. A windscreen and a protective carrying case are also included.

Features

• Specially engineered to meet the most critical acoustic requirements of professional recording, broadcast and sound reinforcement
• High front-to-back rejection ratio—cardioid polar pattern improves 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
