What types of microphones are compatible with the Canon VIXIA HF R700 camcorder? All Canon's documentation states is
Microphone Terminal 3.5mm diameter stereo mini-jack... which lead me to believe that I wouldn't have any trouble. Ideally, I need a conference table mic, like this one:
In fact, this is the first one that I tried... an Audio-Technica PRO 44 Cardioid Condenser Boundary Microphone. We've used this mic with another camera in the office with no problems (we use it with an XLR to 3.5mm plug adapter). Its product page states
This versatile boundary mic’s self-contained electronics eliminate the need for external power modules. Which is one of the reasons I bought it; it requires no external power.
I've tried another similar mic... nothing. Then, just for kicks, I plugged in a Heil Sound PR 20 handheld mic (using the same XLR to 3.5mm adapter as mentioned above) and it worked! And sounded great!
But, sadly, that doesn't solve my problem. It does prove the mic input on the camera is working though.
So what's the deal here? I assumed any unpowered mic would work fine. What kind of mic should I be looking for to ensure compatibility with this camera?
