The mic uses an electret condenser element. The low power requirements of this capsule allow the mic to be powered by either 48V phantom, or a 1.5V AA battery (which fits into the mic handle).

When running on battery power, the mic’s specs change:

The mic’s body construction is all metal, with a “soft touch” finish an an on/off switch.
