I am trying to convert excellent microphone from sony vx1000 camcorder to external one pluggable via jack.

I removed the microphone and was able to find schematics https://i.imgur.com/4T0Zj7X.png I tried connecting jack directly to microphone output (red section in schematics). Later I also connected jack to amplifier output (blue mark in schematics).

I set all of the settings in my other camera I use for testing to off to force it not to adjust audio itself. The audio while working is far from the original one on the vx1000.

When connecting to amplifier output I additionally:

  1. reduced volume with potentiometer (because output from amplifier is too loud for my camera mic in jack input)
  2. Added capacitor to prevent voltage from mic in jack input comming from test camera (according to this
    ). No big changes.
  3. Added impedance control with potentiometer but the results didnt vary much.


  • How it actually sounds:
  • How it should sound:

What else can I do to make it sound exactly like original vx1000?

  • \$\begingroup\$ This question, migrated from sound.stackexchange.com, is a duplicate of the same question which was posted directly to here, a few hours after that one was posted to sound.stackexchange.com. We can't have 2 copies of the same question active at the same time on the same site. So, since this one is the "newly added one here", I've voted to close this one as the duplicate. \$\endgroup\$ – SamGibson Dec 2 '19 at 12:42
