FX1 mic/line input jack
In my opinion, the 1/8" minijack shown above is the only reason the FX1
is not a fully professional camera. Of course there is a pro version,
the Z1U with reliable (XLR) audio connectors, for an additional $1500
or so. I thought the miniplug arrangement would be OK until I
discovered bad audio before a gig, with no time left to debug the
problem. Afterwards I tracked it down to this connector. After
poking at the 1/8" minijack socket from the interior back side it
works again. At any rate, if you are
considering professional work I recommend considering the Z1U instead of the
FX1.
By the way, there are two small surface-mount components mounted near
each of the L + R mic inputs (barely visible in photo above). Using an
ohmmeter, one measures less than 1 ohm, and the other is open. I
suspect these parts are an inductor and capacitor, forming an L-C
lowpass filter that will reduce any RF interference on the low-level
audio signal coming in to the camera.
