The Audio-Technica AT849 is an X/Y stereo condenser boundary microphone with full mono compatibility, intended primarily for surface mount applications in broadcast, professional recording and sound reinforcement. The AT849 provides full, natural stereo ambience in a rugged, compact design.
Equipped with a pair of wide range, optimally positioned miniature condenser cardioid elements, the AT849 provides the spacial impact and realism of a live sound field, while simultaneously remaining full and uniform when operating in mono (L+R). Consistently natural sounding response is maintained over an arc of approximately 220°, and the L+R mono polar pattern is virtually free of lobes and comb effects. Frequency response is smooth and peak free over an extended 30 Hz to 20,000 Hz range, with uniform polar response vs. frequency.
