The white Countryman B2D Lavalier Mic for Audio Technica Wireless Transmittersfrom Countryman B2D Lavalier Mic for Audio Technica Wireless Transmittersfeatures 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 medium gain for very loud speaking, such as in theater performances and most vocals. In addition, the B2D lavalier is equipped with a detachable cable that terminates to a cH-style 4-pin connector for direct connection to Audio Technica ATW-3201 wireless bodypack transmitters.

With its small size and sensitivity options, the B2D can easily hide behind a shirt button. This makes it invisible for film work, theater, live shows, or any other application.

Natural vocal reproduction and a tight polar pattern make the B2D ideal for broadcast and is a dependable workhorse you can count on to perform night after night.

The isolation clips minimize clothing and vibration noise while allowing 360° of rotation for easy positioning of the microphone.

This microphone is tuned to a frequency response that is natural and intelligible at a wide range of distances from the mouth. It delivers wonderful sound quality on the chest (8-10" from the mouth) or towards the collar (3-4").

Related Questions and Answers

Q: 1. I'd like to use this mic on my Canon C70. Is there a XLR 5-pin female to dual mini XLR 3-pin male cable?

A: The BP4025 comes with an XLR 5-pin female to dual XLR 3-pin male Y-cable. We do not a Y-cable with mini-XLR 3-pin male connectors, but you can use adapters to convert standard XLR male to mini-XLR male. The Laird Digital Cinema Premium 3-Pin Standard XLR Female to TA3M 3-Pin Mini XLR Male Audio Adapter (B&H # LARD1XFTA3M) will work or if you prefer longer adapter cables, you can use the Blackmagic Design Set of 2 Mini XLR to XLR Audio Cables for Video Assist 4K - 19.5" (B&H # BLAXLRMINI2). Both of these options will convert the standard XLR male connector to mini-XLR male for compatibility with the C70 mic inputs.

Q: 2. Which capsules are in this microphone - cardioid or omnidirectional? If you use this microphone to record close quiet sounds and whispers, at a distance of about 5-15 cm from the capsule, will it have a strong effect of proximity and distortion, or will it be normal?

A: The capsules in the Audio-Technica BP4025 microphone are cardioid. This microphone would capture whispers at that distance very nicely.

Q: 3. I'm intrigued by the M-S setting, which Lisa described as traditional stereo. I'm wondering if the mic is set to MS, whether it could be used to mic two people sitting very close together for an interview. Possible?

A: The Audio-Technica BP4029 (AT835ST) records in M-S Mode and Left/Right Stereo Modes. Yes you can use it to interview people sitting very close together, up to about 5 feet away from the mic at the very most.

Q: 4. does it have a strobe indicator for speed ?

A: No. There is no strobe.

Q: 5. Am I correct in understanding that this does not require an amp? It has RCA outputs build in that could connect directly to speakers? I am setting up a system in a very small space so looking to keep it compact, but I don't want to buy an all-in-one.

A: You can connect it directly to powered speakers that have RCA inputs since it has a pre-amp built in.

Q: 6. Hi If I need to record sound effects and a quiet voice at a distance of 5-30 cm from the capsules, will the stereo image still be clearly present? I mean a clear separation of right and left.

A: Yes, because the Audio-Technica BP4025 X/Y Stereo Field Recording Microphone uses two individual capsules and offers the ability to keep the signal of each capsule independent of the other for individual recording, it will capture a stereo recording and depict a stereo image of the sound source it is oriented towards.

Q: 7. How is the quality of this microphone compared to a similarly priced mono shotgun? I realize it can't possibly be as good since it is a jack of all trades, but does it compare reasonably well against the rode NTG3 or even the Sennheiser MKE 600?

A: The audio and build quality of the Audio-Technica BP4029 are very good. There are differences in design between the stereo BP4029 and the mono Rode NTG3 and Sennheiser MKE 600 microphones and in the way that they capture sound. Mono and stereo mics are typically used for different applications. The NTG3 and MKE 600 each have one cardioid mic element for a very focused pattern which picks up sound from directly in front of the mic. The stereo BP4029 has a mid-side configuration with separate cardioid and figure-8 mic elements which work together to create a stereo image. The cardioid element is used for "mid" and faces the sound source while the figure-8 element is the "side" mic which is typically aimed at a 90 degree angle from the sound source and creates the left and right split. ​The BP4029 offers three selectable settings -- M-S direct, LR wide, and LR narrow. In M-S mode, the BP4029 provides a traditional stereo sound. In addition to the basic M-S pattern, the BP4029 also offers LR wide mode to pick up more of the ambient sounds for a wider stereo image while the LR narrow mode picks up less of the ambient sound for a more narrow stereo image. The three settings allow the mic to be adjusted based on the recording environment in order to capture the best possible audio. So the mic you select should be based on the application it will be used for, the direction of the audio source, as well as the recording environment.

Q: 8. Which windscreen is suitable for BP4025?

A: You can use the K-Tek KR-50-70 Fur Windsock for Ball-Type Handheld Microphones (B&H # KTKR5070) with the Audio-Technica BP4025 X/Y Stereo Field Recording Microphone. It is suitable for both indoor and outdoor applications.

Q: 9. What is the length of the boom arm when folded closed and the clamp removed?

A: The folded length of the Audio-Technica AT8700 Adjustable Microphone Boom Arm BH #AUAT8700 with the clamp removed is approximately 16 inches.

Q: 10. Can any 5-Pin XLR Female to 1/8" 3.5mm Stereo Jack can be used to connect the AT BP4029 to Canon R5 camera? If so, which one do you recommend?

A: The Audio-Technica BP4029 (AT835ST) - Stereo Shotgun Microphone requires power from 3-Pin XLR inputs to operate properly and cannot connect directly to a 3.5mm input on a camera such as the Canon R5. A small camera mixer such as BH #SASRPAX1 Saramonic SR-PAX1 Two-Channel Audio Mixer, Preamp, Microphone Adapter would work to achieve this setup properly.
