Audio-Technica AT4051b Cardioid Studio Broadcast Recording Condenser Microphone

Ideal for professional recording and critical applications in broadcast, the Audio-Technica AT4051b Cardioid Studio Broadcast Recording Condenser Microphone is a versatile studio performer. This microphone is engineered to deliver exceptional performance across a wide variety of professional miking applications. With direct-coupled balanced outputs, it ensures clean signals in high-output conditions, completely free of the distortion associated with conventional transformer-coupled outputs. Its rapid response to transients contributes to the open, transparent reproduction of even the most challenging instruments.

The AT4051b is compliant with RoHS (Restriction of Hazardous Substances), ensuring that it is free from all substances specified in the EU directive on the reduction of hazardous substances. The microphone consists of two modular subassemblies: an AT4900b-48 body and an AT4051b-EL cardioid head capsule, both of which are available separately. For added versatility, interchangeable capsules are available in omnidirectional (AT4049b-EL) and hypercardioid (AT4053b-EL).

Key Features
