**Phantom Power: ON/OFF**
**Mic Power: ON/OFF**
This is required for internal mic and certain types of external mics, but it reduces input impedance. See `AK4646 datasheet p.31 <http://www.vimeo.com/groups/magiclantern/view_file:9434>`_ and the `Mic power control <http://groups.google.com/group/ml-devel/browse_thread/thread/516d22e75dcb9357>`_ thread.

* ``ON``: input impedance is 2 kOhm
* ``OFF``: input impedance is 30 kOhm
