Audio-Technica AT4049b Omnidirectional Broadcast Recording Condenser Microphone

Audio-Technica AT4049b Omnidirectional Broadcast Recording Condenser Microphone

The Audio-Technica AT4049b Omnidirectional Broadcast Recording Condenser Microphone is specifically designed for professional recording and critical applications in broadcast environments. This versatile microphone can confidently be used in a wide array of professional miking scenarios. With its direct-coupled balanced outputs, the AT4049b ensures clean signals even in high-output conditions, eliminating the distortion typically associated with conventional transformer-coupled outputs. The microphone’s fast transient response contributes to its open, transparent reproduction, making it ideal for capturing even the most challenging instruments. In compliance with the EU directive on the reduction of hazardous substances (RoHS), the AT4049b is completely free from all specified harmful substances.

The AT4049b consists of two modular subassemblies: the AT4900b-48 body and the AT4049b-EL omnidirectional head capsule, both available separately. Additionally, users can opt for interchangeable capsules available in cardioid (AT4051b-EL) and hypercardioid (AT4053b-EL) patterns, allowing for greater versatility in various recording scenarios.
