AT897 Line + Gradient Condenser Microphone

Audio-Technica’s AT897 is designed for field audio acquisition in film/TV/video production, professional recording, wildlife recording and broadcast applications. It mounts conveniently on a DV camcorder without adding noticeable heft, and remains out of the frame even with compact digital cameras. This high-performance short shotgun offers outstanding long-distance audio pickup due to narrow acceptance angle of line + gradient design. It also features smooth, natural-sounding on-axis audio quality and excellent off-axis rejection of sound arriving from the sides and rear of mic.

Distance to pick up

hello~

I need a microphone to pick up a theater production live for a small church. i was thinking about getting this mic to pick up the play by installing this mic at the front of the stage, pointing upwards towards the actors. i tried just putting up two condenser mics on stands at the end of the stage, but the distance was too far for them to pick up the voices, and they were obtrusive in view.

the stage is about 20 feet wide, and maybe about 8 feet deep. I was thinking about putting this mic on the floor, in front of the stage, pointing up at an angle towards the actors.

let me know if you think this mic would suffice that need, or if you need more information.

thank you!

Answer: 
Thank you for your inquiry. We have customers that use this microphone just as you suggest. Please note that distance micing will not sound the same as a microphone worn by the performer. There will be some room in the audio. Also, shotgun microphones do well at distance micing because of the side rejection capabilities of the microphone. Think of it visually as if you are staring at an object through a cardboard paper towel tube. The item is no closer, but you see less things around it. Same thing with the shotgun microphone. It's not that you are actually zooming in on a particular sound source as much as you are rejecting sounds around it.

Thank you for your inquiry. You should try to keep any microphone as dry as possible. After use in a wet environment, dry the microphone as best as possible, even using a hair dryer if necessary. Store the microphone with a desiccant if possible to absorb moisure.

Boom mic for video

I'd like to use this shotgun mic on a boom in conjunction with a Pro 88W lav mic to capture stereo audio into a Zoom recorder for on-location video interviews. Is this an acceptable solution for high quality audio?

Answer: 
Thank you for your inquiry. I assume that you plan to use the shotgun mic as well as a lav mic at the same time. This could be a good approach, although it could also not work out so well due to the two mics cancelling each other out if they are not carefully placed. This also, is not a very good stereo micing technique.

AT897

Sometimes I cannot get a XLR feed from my church's sound board and have to use a shotgun mic. I shoot using a Panasonic AG-HMC40 from the balcony at about 50 feet to stage. The large house speakers are at eye level and at about 35 to 40 feet away. My question is do you think that the AT897 is a good choice for me.

Answer: 
Thank you for your inquiry. It is possible this could work depending upon how loud your source is. There is a professional blues band that I know of that records every concert using a pair of these from front of house and it sounds very nice. Of course these guys are very loud.

I would like to get an external mic for my Panasonic HDC TM900 camcorder. The specifications only say:
MIC input: -70 dBV (Mic sensitivity -50 dB equivalent, 0 dB=1 V/Pa, 1 kHz) (Stereo mini jack).

My questions:
1) will this mic work well with this camcorder?
2) I plan to video insects and often they will be a foot away or closer. Will the mic work well at these close distances?
3) Are there other mics I should consider instead?

Thanks

Answer: 
Thank you for your inquiry. To use this mic you will have to have an XLR female to 3.5m male trs cable. The mic is fairly sensitive, but not overly so. I don't know it it will pick up insect sounds or not. A more sensitive mic like our BP4071 would be more likely to pick up these sounds, but it will not work with your camera without a phantom power source.
