    AT875R Line + Gradient Condenser Microphone 5 5 1 1
    Great on-camera sound & convenience 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. July 7, 2012

    What is "Phantom Power"?

    What is "Phantom Power"?
    \What I really need to know is will the at875r work with a Canon XR10?
    If not, is there an adapter or what mic should I use?

    Thank you

    Answer: 
    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 practical check is to know that you always need to have three outgoing connections to send phantom power out of a recording device (in this case your camera).

    XLR has three pins in one plug.
    TRS has three separate metal connections on one plug (TRS stands for the three which are tip,ring,sleeve).

    Because of this using a simple cable adapter that converts from three pins on the mic end to two connections on the camera side won't work. Obviously one of the three pins isn't connected in the adapter.

    A quick check of your owners manual for camera or recording device will tell you if it's capable of outputting phantom power. Look for the ability to switch the phantom power on and off.. most devices that will supply phantom power allow you to turn phantom power off to save battery power.

    The important part of your answer is the solution. How do you use a mic that requires phantom power with your camera that does not provide phantom power.
    Two ways. First some mics that require phantom power can power themselves with an on-mic battery. Second you can buy an adapter to go between the mic and the camera that provides phantom power. There are many powered adapters available that will do this.

    So simple adapter cable no. Phantom power adapter device yes.

    So why use phantom power at all? Well the mics that use it are much more sensitive and can pick up fine details in the sound they are recording.
    An added bonus is with three wires in the mic cable the signal can be transferred in a way that cancels noise that is picked up by the cable (you aren't an engineer so I won't explain how it works).
    If you only use a mic cable that is a few inches long the noise picked up isn't an issue so you can get away with a two wire cable.
    Anything longer do yourself a favor. Use the much more capable three wire cable with a phantom powered mic. You get more detailed sound and low noise at the same time.

    Answer: 
    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.

    A balanced mic cable has three conductors; Pin 1 is ground, Pin 2 is audio positive, and Pin 3 is audio negative. Most microphones produce a positive voltage on Pin 2 when sound pressure is applied to the diaphragm.

    Phantom power is 9 - 52VDC applied across Pin 1 and Pin 2 - and at the same time applied across Pin 1 and Pin 3. The term 'phantom power' was assigned because if you take a measurement across the two audio lines - Pin 2 and Pin 3 - you find 0 Volts DC. The voltage does not affect the mic signal.

    Your camera must provide phantom power in order to use this microphone.

    I'm doing interior video work. Shots of two speakers. standing 2 to 10 feet apart at 8 to 30 feet away from the mic. Mic will be on or near camera.
    The polar pattern on the 8035 looks slightly more directional. I would rather have the mic that offers both battery and phantom power.

    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.

    I am unsure if my h4n recorder will be compatible with this mic because I am unsure if the 3 prong XLRM-type that this mic has is the same as the XLR input the h4n has. If they are different I can just get an appropriate cable-I just don't know if they are indeed different or if the h4n is abbreviating the term.

    Answer: 
    yes,
    xlr is the connector type. xlrm (male) plugs into xlrf (female). so the connector on the end of the cable is female. the connection on the mic has pins sticking out (male).

    you are compatible, only question is does your recorder have phantom power? if it does you are all set. if not make sure you use a self powered mic.
