Audio-Technica AT4051B Cardioid Condenser Microphone

The Audio-Technica AT4051B Cardioid Condenser Microphone is a versatile studio performer designed for professional recording, broadcast, and sound reinforcement. This end-address microphone meets critical acoustic requirements by providing transparent audio reproduction for difficult-to-capture instruments and high-output conditions.

Advanced Circuitry and Signal Integrity

The AT4051B utilizes direct-coupled balanced outputs to maintain signal cleanliness even in high-output environments. The transformerless circuitry virtually eliminates the low-frequency distortion common in conventional transformer-coupled designs. This architecture ensures superior correlation of high-speed transients, resulting in an open and transparent sound profile.

Acoustic Performance and Isolation

The cardioid polar pattern provides a high front-to-back rejection ratio, which improves the isolation of the primary sound source. This directional characteristic minimizes unwanted noise from the sides and rear, making it an ideal choice for critical miking applications where precision is required. Its fast response to transients allows for the accurate capture of complex acoustic nuances.

Modular Design and Construction

The AT4051B features a modular design consisting of two subassemblies: the AT4900b-48 body and the AT4051b-EL cardioid head capsule. This system supports versatility through additional interchangeable capsules, including omnidirectional and hypercardioid options. The microphone housing is constructed from rugged turned brass to ensure enduring dependability and professional-grade durability.

Integrated Performance Controls

To accommodate various recording environments, the microphone includes a switchable 80 Hz hi-pass filter and a 10 dB pad. These controls allow users to manage low-frequency noise and high sound pressure levels without sacrificing signal quality.

Manufacturing Standards and Compliance

Audio-Technica employs state-of-the-art design and manufacturing techniques to ensure the AT4051B meets stringent consistency and reliability standards. The microphone is fully RoHS-compliant and free from all hazardous substances specified in the EU directive on the reduction of hazardous substances.
