    Does anyone know the impedance of the audio circuit on the OM-D? I can't find anything listed on Olympus' site.

    Input or output?

    Output is line level, for TVs and monitors.

    This is the mic designed to work with Olympus m43 camera's.

    The ME51S stereo microphone can be plugged into the earphone/microphone/remote control socket to give fantastic quality stereo recording. Also includes a 3.3 foot extension cable with tiepin-clip. The recording level indicator for the right and left channels is visible in the LCD display during recording. Specifications: Type: Stereo electret condenser microphone Microphone dimensions: 38(L) x 14(B) x 40(H)mm Plug: 3.5mm stereo Frequency Response: 100 - 15,000 Hz Directivity: Uni-directional x 2 Mike Sensitivity: -40db at 1 kHz Output Impedance: 2.2kOhms Power Supply: Plug-in-power system (1.5V - 10V) Color: Silver and Black microphone Weight: 7 grams main unit, 18 grams including extension cable and tiepin clip Item #145037

    Line level defines p-p voltage range and not impedance (complex AC resistance).

    Yes but there are high impedance AND low impedance mics. It might be best to select a mic that is balanced for the audio circuit (camera) it is feeding rather than adding an adapter later.
