Comments about Audio-Technica AT875R Line + Gradient Condenser Microphone:
The AT875R performs very well for its price. But I won't say much about that, because it is easy to find audio samples online and hear for yourself.
What sets this mic apart is its ability to operate from a low voltage power source. The mic is spec'd for a minimum supply voltage of 11 volts, but it operates quite happily on as little as 2.4 volts, as supplied by the plug-in power mic ports of many camcorders and DSLRs. You just need a cable with 2.5-mm or 3.5-mm plug for your camera and an XLR connector for the mic, wired as described in Audio-Technica's own FAQ on this web site, "How do you unbalance a balanced audio line so you can drive an unbalanced input?" Wire XLR pin 2 to the tip and the ring, and XLR pins 1 and 3 to the sleeve.
Operating the mic at a lower voltage must alter its performance somehow, but I've noticed no reduction in performance. My guess is that there is a reduction of the maximum SPL before distortion that would only have an impact in very loud settings, and also a very slight reduction in the sensitivity.
Powering the mic from the camera adds a huge amount of convenience, because you no longer need to worry about keeping batteries charged, turning a mic on and off, or dealing with external converters or pre-amplifiers. I use the AT875R with a Panasonic GH2. Others have reported using it with the GH1 and the Canon T2i. The AT875R is more sensitive than many mics, which helps to compensates for the poor performance of the pre-amps in many cameras.
I don't think you can find a better sounding directional on-camera mic with this price and this level of convenience.

Q:We are doing instructional videos, with a stationary presenter on green-screen background doing a short introduction. We need an off-camera mic. on a boom, located about 2-3 feet away / above the presenter to record the audio to a tascam HD40 recorder, which will then be imported into our video editing program. The room is not acoustically treated, but could be if needed. Is this mic a good choice, or would you recommend another model for our application?
Q:Is there an adapter that will allow me to use this mic with a computer?
A:Please contact our Audio Solutions Department at (330) 686-2600 ext 5000 or at email@example.com for assistance with this.
Q:What is the self noise specification (CCIR or DIN/IEC A-weighted)?
A:AT875R: SIGNAL-TO-NOISE RATIO
Q:DsLR compatible microphone
A:Thank you for your inquiry. Something like our AT897 which will operate via phantom power or battery should work for your application.
Q:How much of the AT875R's length do the ports occupy?
A:Thank you for your inquiry. From the end to the last vent is 4.25".
Q:Is this product TAA compliant AT875R
A:The AT875R Microphone is made in Japan.
Q:Is the 3 prong XLRM-type just an xlr cable?
Q:What is "Phantom Power"?
A:Phantom Power for practical purposes is powering a microphone with its signal cable. Some mic types require power to operate and some don't.
A:Thank you for your inquiry. Phantom power is DC voltage sent down the microphone cable to power the preamplifier of a condenser mic capsule - sometimes through a power module. The power module attached to the mic unit converts the 9 - 52VDC into a small bias voltage that the mic capsule’s FET needs for the microphone to operate.
Q:Hi ~ I am trying to connect this mic using an adapter to convert to a mini mic input jack for a Canon DV - GL-1 camcorder. I'm not getting a signal?
A:Thank you for your inquiry. This microphone requires phantom power from the device it is connected to. A 3.5mm mini jack does not provide phantom power.
Q:AT8035 or AT875R, for 2 shots interior at 8-30 feet
A:Thank you for your inquiry. The AT8035 appears to be the mic that will most meet your need in the application.
