Thanks for choosing the Countryman B2D Directional Lavalier.

The B2D 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.

This booklet describes how to use the B2D to get the best performance in a variety of different applications.

Microphone Care

While the B2D Lavalier is designed for durability, moisture-resistance, and ﬂexibility, it is a highprecision instrument and we do suggest some basic precautions to prevent damage or sonic degradation:

• Always use the B2D with its cap in place. The

cap is critical to the sound quality and also protects the capsule from makeup, moisture, and debris.

• When a protective cap is not in place, avoid

touching the end of the capsule with ﬁngers or obstructing the opening with foreign substances.

• Remove the cap for cleaning. The cable and cap

may be cleaned with alcohol wipes, soap and water, or spirit gum remover. Do not use water or

any chemicals on the capsule itself.

Always use the B2D with the cap ﬁrmly in place.



ONLY remove the cap to clean it. The B2D will not function correctly without the cap.

Using the Single Microphone Clip

Place the top isolating sleeve into the groove in the microphone holder.

Pinch and clip the microphone holder into the base.

Slide the second isolating sleeve about one inch down the cable and clip in into the gripper. For ties, button down shirts, and jackets, position the clip horizontally; for t-shirts and many dresses you can rotate the clip vertically.

Using the Magnetic Clip Using the Double Microphone Clip

The Magnetic Clip consists of a magnetic gripper and backplate. The backplate slips behind clothing or other surfaces for secure positioning on sensitive fabrics or hard-to-mic locations. Loop the backplate’s attached lanyard arond the neck for easy retrival.

The Magnetic Clip is not suitable for persons with pacemakers.

The Double Clip provides an additional microphone holder. This is ideal for a redundant B2D, or a backup omnidirectional lavalier, such as the B6 or B3.

Positioning the Microphone

• Position the B2D Lavalier about 8” to 10” from the mouth for chest miking and rotate the microphone toward the mouth.

• Use the windscreen whenever practical. Placing the microphone to one side can help reduce breath noise.

• Placing a small loop in the cable and taping it to the inside of a shirt or jacket can reduce cable noise.

• When hiding the microphone, never obstruct any part of the protective cap, including the back port at the rear-most

rim of the cap.

Additional Microphone Placements

The small size and consistent pattern of the B2D make it particularly versatile:

Buttonhole Hair Eyeglasses Podium Backup

Ensure the entire cap of the B2D is exposed. Including small loops and taping the cable will help reduce handling noise.

Excellent for theater. Use hair berets to secure the cable. If you use tape on the skin, make sure the entire B2D cap is exposed.

Heat shrink and a bent piece of wire hold the B2D in place. Point the capsule at the mouth (microphone extended for visibility).

Black electrical tape holds the B2D under a podium microphone for redundancy. The technique also works well with omni B6 mics.

Detachable and Fixed Connectors

The B2D is available with threaded detachable connectors or permanently-attached connectors in a variety of conﬁgurations to suit hardwired systems and wireless transmitters. Make sure detachable connectors are ﬁrmly hand tightened before use. Both styles feature generous ﬂex and strain reliefs bonded to Countryman’s custom 1.5mm aramid-reinforced cable for more than 45 pounds of break strength.
