Countryman B2DW4FF05BSNF
FF05BSNF Lavalier Microphone for Sony Transmitters, in Black


This Countryman B2D microphone is the B2DW4FF05BSNF model, a directional lavalier microphone designed specifically for use with the Sony SRT-805A, UWP Series, UTX-B1, UTX-B2, and UTX-B03 transmitters (all sold separately). This particular model also comes in the W4 (Standard gain) configuration and features a black finish. It has a permanently-attached connector with generous flex and strain reliefs that are bonded to Countryman's custom 1.5mm aramid-reinfored cable which provides more than 45 lbs of break strength.

Easily the smallest directional lavalier in the world—with the next smallest mic being more than twice its size—the B2D is a tiny package that opens up a new set of miking options that were previously unavailable, combined with exceptional sound quality and isolation. 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.

Countryman B2D Includes:

  • B2D Directional lavalier microphone (with permanently-attached connector)
  • Carrying case
  • Single isolation clip
  • Windscreen
  • Protective cap
