Audio-Technica AT4900b-48 Condenser Modular Microphone Body

Audio-Technica AT4900b-48 Condenser Modular Microphone Body

The Audio-Technica AT4900b-48 Condenser Modular Microphone Body is designed for professional recording and critical applications in broadcast environments. This versatile microphone provides top-notch performance across a wide array of professional miking applications. It features direct-coupled balanced outputs which ensure clean signals even in high-output conditions, eliminating the distortion typically associated with conventional transformer-coupled outputs. The fast response to transients contributes to the open and transparent reproduction of even the most challenging instruments.

The AT4900b-48 is fully compliant with the EU directive on the reduction of hazardous substances (RoHS), meaning it’s free from all specified harmful substances. The AT4900b-48 is part of a modular system, composed of the AT4900b-48 body and the AT4049b-EL omnidirectional head capsule (available separately). Additional interchangeable capsules such as the cardioid AT4051b-EL and hypercardioid AT4053b-EL are also available, providing greater flexibility to meet your specific needs.
