Primo Phantom Power New Sony Cameras


Testing stereo Primo EM272 microphones plugged right into a Sony A7III camera this time filmin fall foliage half an hour before sunset in Holland. The right audio level is substantially higher than the left channel level. I restored stereo balance editing in Final Cut Pro X : changing Pan settings to Stereo Left/Right shifting -50% direction left channel. The same effect was noticed again today with the stereo Primos plugged in my Sony ZV-1 camera – as reported before over the past days (though then with an angle adaptor in between). The problem did not occur when testing today the Sennheiser MKE 440 stereo mic plugged the same wayy in both cameras – so the imbalance is not due to some mechanical problem with the 3.5 mm plug port of the cameras.
Further stereo balance of the Primo EM272 microphones was perfect in audiorecorders – the Olympus LS-P4 tested today , and my old (2008) LS10 tested some days ago.
For now , I conclude the imbalance is somehow related with / due to the plug-in-power needed by the Primo mics from the camras – the Sennheiser doesn’t require plugin power… Note the required Phantom power (Plug-in-power) is no handicap with the dedicated audiorecorders.

Earbags … Binaural Primo EM272 Microphone


Binaural sound test with Primo EM272 external microphones inserted in Earbags as ‘headset’, plugged in the Sony ZV-1 camera with audio level 15 the first minute, and level 20 the next minute.
Recordings like this in my ZV-1 camera need rebalancing in Post (FCPX) of the Stereo Left/Right to around -50% (shift to left channel). I am not sure right now after these first tests (done Oct 31th at home in the garden) whether the camera is the problem because I used a 3.5 mm right-angle adaptor to hook up the Primo mics cable to the camera, that may have caused this. However the Primo mics gave perfectly balanced left/right recordings in my Olympus LS-10 field recorder.
