B2D DIRECTIONAL

LAVALIER MICROPHONE

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 B2D

With 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 under­clothing miking.

Great for Broadcast

Natural 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.

Supplied with a 5’ cable, carrying case, windscreen, single

isolation clip, protective cap, and detachable connector.

Frequency Response : 50 Hz to 18 kHz

B2D Directional Lavalier: Features and Use

Isolation Clips

Our isolation clips minimize clothing and vibration noise,
while allowing 360 degree rotation of the mic for easy
positioning. We offer single and double isolation clips—as

well as a magnetic isolation clip—in five different colors.

Frequency Response

We tuned the B2D frequency response to be natural and
intelligible at a wide range of distances from the mouth.
As a result, the B2D delivers exceptional sound quality on
the chest (8-10 in. from mouth) or towards the collar (3-4
in.).

Detachable Connectors

The B2D detachable connectors interface to a wide
variety of wireless transmitter packs or an XLR input. This
feature provides extreme flexibility for rental companies,
consultants, or anyone else working at multiple venues or
with different wireless systems.

Three Sensitivity Options

The B2D is available in three different sensitivity options—
lower sensitivity means higher overload level. Choose W4
for standard chest-worn applications, W5 for close miking
such as on eyeglasses (shown here), and W6 for close
miking with very powerful vocals: opera, for example.

Redundant Miking

With our double tie clip, two B2D microphones—or one
B2D and one B6 or B3 Omnidirectional Lavalier—can be
used for redundancy. Pairing the B2D with the omni lav
provides tremendous control to the sound engineer who
can decide at any time to pan to the directional or the
omni to get the best sound quality.

Five Color Options

The B2D is available in five colors: white, light beige, tan,
cocoa, and black. Black is most popular for standard
lapel-worn applications. Tan, light beige, and cocoa are
designed to match clothing and skin tones. White is great
when placing the B2D through a button-hole or against
white clothing.
