Achieve clear, intelligible speech reproduction and easy local switching with the black Audio-Technica U891Rb, 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.

Related Questions and Answers

Q: 1. Is anyone using 2 of these simultaneously with the tascam dr-40 and if so, does the phantom power from the tascam do ok? How long can you record with a new set of batteries? Thanks

A: I do not own a Tascam dr-40, but we used 2 of these with phantom power from a Canon XA-10 and they worked well. It may be a decent alternative to a bunch of lav mics and a mixing board.

Q: 2. Do I need a pre-amp to connect it to a laptop?

A: The Audio-Technica Pro 35 Cardioid Condenser Instrument Microphone requires a USB audio interface with XLR inputs for connection to a computer.

Q: 3. I'm a little confused about their statement Self-contained electronics eliminate need for external power modules . It IS a condenser mic. I am assuming it still requires phantom power. Would the 12v phantom power from a typical shure mic mixer provide adequate performance?

A: It is a 48volt phantom powered mic. Whether or not it can work on 12 volts can be answered by reading the spec on the AT web site.

Q: 4. Would this be compatible with a Panasonic GH4 video camera? Or is there a particular adapter/connector required?

A: It has a full-size XLR connection. What input does your camera need? If you've got pro XLR you're all set. This is a great mic! If you have an 1/8 input, this isn't your microphone. :(

Q: 5. Does this mic come in a wireless version?

A: This mic is not available in a wireless version.

Q: 6. 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.

Q: 7. 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: 8. Where can I get a wind cover for this microphone?

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

Q: 9. 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: 10. Will this mic work on a DSLR?

A: Yes. I use it with a DSLR as well as a basic consumer level camcorder. Youll need a 3.5mm to 3-Pin XLR Female adapter cable though.
