Achieve clear, intelligible speech reproduction and easy local switching with the white Audio-Technica U891RWb, a cardioid condenser boundary microphone optimized for surface-mount applications in conference rooms, houses of worship, recording studios, live event venues, and sports arenas. The local touch-sensitive switch offers three modes for customizable control of talk/mute functions, and the microphone's on/off status is indicated by a two-state RGB LED. The high-output condenser element yields a wide frequency response of 20 Hz to 20 kHz, which can be modified via the switchable 80 Hz low-cut filter—ideal for mitigating rumble and low-frequency buildup.

The cardioid polar pattern delivers directional pickup and enhanced off-axis rejection, allowing reduced ambience and high gain before feedback. Thanks to the UniGuard RFI-shielding technology, the U891RWb impedes radio frequency interference from sources such as wireless devices, fluorescent lights, air conditioners, and more. It can be powered by 11 to 52 VDC phantom power, so no batteries or external power supplies are required. The rotatable balanced TB3M output connects to the included 25' TA3F to XLR microphone cable, ensuring easy hookup to your mixer, preamplifier, or audio interface.

Related Questions and Answers

Q: 1. Where can I get a wind cover for this microphone?

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

Q: 2. What adapter / connector does it take?

A: The power module connected to the Pro 70 lavaier features a male XLR connection. The proper cable or adapter will depend on the device you are connecting to.

Q: 3. i am a youtuber, would this work with pranks? like use it as a mic with a distant camera and itd record the audio??

A: Unfortunately not. The Audio-Technica Pro 70 is not a wireless mic. It has a standard XLR mic cable. If you want to record audio at a distance from your camera then you would need to buy a wireless system.

Q: 4. Is there a hanging XY mount for these mics?

A: No, I have not found one yet.

Q: 5. What is the best choice to small school auditorium, the omnidirectional or Hipercardiode ?

A: Omni-directional mics are more susceptible to feedback, especially in smaller spaces. A Hypercardioid microphone usually provide the best gain before feedback ratio, however they are not very forgiving and strategic placement is critical in order to get satisfactory results. One nay consider a cardioid polar pattern as they are more forgiving; not too broad to pick overly pick up background noise, but not so directional to the point that a user must be right on the mic for an audible recording or amplification.

Q: 6. is there a good wind screen for this microphone? It is very sensitive to wind.

A: You can use the Auray Fuzzy Windbuster for Lavalier Microphones - Black (B&H # AUWLW) or Rycote Lavalier Windjammer - Black (B&H # RYWFLB). If you prefer a foam windscreen, the Auray WLF-038-3R Foam Windscreens for 3/8" Diameter Microphones - 3 Pack (B&H # AUWLF0383R) or Audio-Technica AT8116 Mini Lavalier Windscreen (B&H # AUAT8116) are compatible.

Q: 7. I'm theatre director in a school with a carpeted (throughout-including stage)lecture hall venue that we use as our theatre. Maximum size- 300 people. No curtains, fly space, wings, etc. Quality Sound has been tricky for years. Would this be appropriate for my situation?

A: We bought two of these for our church and they worked well. However, I not sure we are using them to there best ability. They did allow people to hear the drama btter. Hope that helps. And I believe you have a 30 day return policy with B&H.

Q: 8. I bought two of these mics. I record a podcast in a car and use these mics. The problem is that it seems that any movement of the mic cable causes feedback in the recording... I don't understand why it is so sensitive. An arm brushing up to the mic cause noticeable audio distortion. any ideas?

A: could be a bad cable, or connection. If same thing is happening with both mics, try either with windscreen on, with windscreen off.

Q: 9. I have the pro70 and a XLR3F to 3.5 mm TRS cable but I'm not able to record audio with my iPhone with this setup. What am I missing?

A: Smartphones feature a jack that carries both headphone and mic signal. These are not directly compatible with a standard 3.5mm TRS connector. In order to use the Pro70 with an iPhone, you will need an additional adapter with the cable you already have such as the MyMyk connection cable a href= http://bhpho.to/162F02q. target= _blank http://bhpho.to/162F02q./a There is also a single cable solution from Sescom that will allow an XLR connection directly to the phone. See the following link: a href= http://bhpho.to/1E8vFQB target= _blank http://bhpho.to/1E8vFQB/a This cable also allows you to keep the headphone connection as well.

Q: 10. Do I need a power module or can I just plug this into a mini-XLR to XLR adapter and power it with phantom?

A: This version of it has an unterminated cable. This one (AUAT831B) comes with the power module and then you can take an xlr cable out of the module.
