AT849 Stereo Boundary Microphone (DISCONTINUED)

Designed for surface-mount use in high-quality sound reinforcement, broadcasting and recording applications, this robust microphone delivers clear and intelligible audio reproduction. With true stereo output and twin XLR output connectors, the AT849 features closely matched, optimally positioned elements that deliver the spatial impact and realism of a live sound field. The microphone’s heavy die-cast case and rubber bottom pad minimize coupling of surface vibration. The mic features switchable low-frequency roll-off and low-profile design for minimum visibility.
