The tan B2D Directional Lavalier Mic, Low Gain, with Detachable TA3F Connector Cable for AKG Wireless Transmitters from Countryman features a lightweight 0.18-ounce body that was designed to be discreetly mounted and can be used for miking news anchors, actors in a film or theater setting, lecturers in a school or house of worship type environment.
The B2D's tight hypercardioid pattern gives the mic an extra 6-10 dB of headroom compared to an omnidirectional lavalier mic, which means less problems with feedback, ambient noise, room rumble, and phase cancellations when using multiple microphones.
This version offers the lowest gain for powerful vocals such as in opera, which requires a higher overload level. In addition, the B2D lavalier is equipped with a detachable cable that terminates to a TA3F connector for direct connection to AKG DPT800, DPT700, PT2000, PT40, PT400, PT4000, PT45, PT450, PT4500, PT470, PT60, PT61, PT80, and PT81 wireless bodypack transmitters.
