The B2D Directional Lavalier is easily the smallest directional lavalier in the world, with the next smallest mic being more than twice its size. Combined with exceptional sound quality and isolation, this tiny package opens up a new set of miking options that were previously unavailable. The tight hypercardioid pattern gives the B2D an extra 6-10 dB of headroom compared to an omni lav, meaning less problems with feedback, ambient noise, room rumble, and phase cancellations with multiple mics. Positioning the B2DWith its small size and multiple color and sensitivity options, the B2D can easily hide behind a shirt button, making it truly invisible for film work, theater, live shows, or any other applications that may otherwise have required the reduced sound quality of under-clothing miking. Great for BroadcastNatural vocal reproduction, superb intelligibility and a tight polar pattern make the B2D ideal for broadcast and a dependable workhorse you can count on to perform night after night in the most critical applications.
