The Audio-Technica AT5047 is a cardioid studio condenser microphone designed to provide engineers and musicians with an accurate, low-noise reproduction of vocals and instruments in high-end facilities, project studios, and home recording setups. It features four rectangular 2-micron, vapor-deposited gold diaphragms, which offer double the surface area of the 1” circular diaphragms commonly used in large-diaphragm condenser mics. The AT5047’s transformer-coupled output yields a consistent impedance for reliable performance with your preamp.

A wide frequency response of 20 Hz to 20 kHz—combined with the ability to handle a maximum SPL of 148 dB—means that you can capture a variety of sources, from soft and nuanced to loud and brash, with detail and accuracy. By producing only 6 dB of self-noise, the mic contributes to a clean and clear signal.

The AT5047 is assembled by hand and housed in a durable enclosure made of aluminum and brass. It ships with a custom shockmount and hardshell carrying case.

Q: 1. I have a Tascam DR-701R that provide phantom power, so still I need piut the Battery in the AT831B?

A: It is battery or phantom. So you can run it with the phantom power on your DR-701, or if you would like to save some battery power on your DR-701, you can run the AT831B on battery power.

Q: 2. Does this microphone have GSM or cell phone interference? I have the AT803b, and I get interference from GSM cell phones near the microphone.

A: I haven't noticed cell interference, but it does have a ton of handling noise. Even the faintest fabric rustle is pretty noticeable.

Q: 3. Hello. I wonder how noisy it is? How does it work for recording low volume stuff?

A: The AT2021 Cardioid Condenser Microphone is designed for general instrument capturing, vocals, amplifier cabinets, and similar applications. It's signal to noise ratio is 75db and has a max SPL of 145db. It features a Cardioid polar pattern, reducing sound pickup from the sides and rear, improving isolation of the desired sound source.

Q: 4. Can you recommend a preamp/power supply for this mic? I don't need a mixer as I plan to feed the mic into an ATEM mini with an adapter

A: You can use the Rolls MP13 Mini-Mic Preamp (B&H # ROMP13) to power the Audio-Technica U851Rb Cardioid Condenser Boundary Microphone, then use an XLR female to 3.5mm TRS male cable like the Kopul XRSM 3-Pin XLR Female to 3.5mm RA Stereo Mini-Plug Cable - 3' (B&H # KOXRSM03B) to connect the output from the MP13 to the 3.5mm TRS input on the Blackmagic Design ATEM Mini HDMI Switcher.

Q: 5. I'm looking for the best possible lavalier microphone for professional videography. I currently have an NTG3 Rode Shotgun Mic, so I'd want to match that quality with a lavalier that can be used on a ursa mini 4k with XLR inputs, wireless to the lavalier location. I'd appreciate any suggestions for budget and best for price, what do the experts think?

A: I have a rode NTG2 and this mic. I just used it on a documentary I filmed with a Sony NX5U and it sounded great and I got several comments on the audio quality. I have had mu eye on the URSA Mini, what are your thoughts on the URSA, would you recommend it?

Q: 6. Could this mic also be used as an overhead for an interview with good results?

A: Unlikely. It is not designed for that purpose. Dependant on distance and room acoustics; this mic is designed for close proximity, generally within inches of a musical instrument. That said, in a quiet room, with 1-2' of distance this mic MAY obtain good results for a single person.

Q: 7. Where can I get a wind cover for this microphone?

A: Auray - Fuzzy Windbuster for Lavalier Microphones (Black) B&H# AUWLW

Q: 8. Can I plug this into my Sony HandyCam (Camcorder)?

A: In order to connect the AT 831B to a camcorder with 1/8 input, you will need to insert batteries into the mics power supply module. You will also need to adapt the output with a special adapter such as the Kopul LMT-100. a href= http://bhpho.to/1yMIinD target= _blank http://bhpho.to/1yMIinD/a

Q: 9. Using for interviews.I'm getting a lot of noise from this microphone that I wouldn't expect. Very sensitive to any movement near the microphone like a jacket moving, heavy breaths causes overmodulation. I use the windscreen at all times and that helps some. It's pretty annoying. I've used dozens of mics over the years and have never had this much problems. Am I doing something wrong?Any suggestions? Would a unidirectional mic be better.

A: The Audio-Technica AT831B is a unidirectional microphone, suitable for professional video, broadcast and sound reinforcement applications. The fact that it is a condenser makes it more sensitive than your traditional dynamic hand-held interview mic. In video production, condensers are preferred because of their sensitivity- especially when pristine audio is demanded. In your case, I would try a couple of things before considering a mic change. 1. Engage the low-cut filter. The power switch has three positions: off , flat , and low-cut . The low-cut filter makes the microphone less sensitive to low frequencies found in wind, breath noise, and general ambiance. 2. Consider adding the Rycote Undercover (B&H#RYUC) lavalier wind cover and adhesive mount to your sound bag. The covers help reduce rustling noise caused by cable movement and friction between the mic element and clothing.

Q: 10. what applications are best for this mic?

A: The ATM450 Cardioid Condenser Instrument Microphone from Audio-Technica is designed with a side-address capsule, allowing for easy placement and flexible positioning on percussion, guitar cabinets, piano, and similar applications.
