CardioidKarma Audio K10

Detachable-Capsule Pencil Condenser Microphone


The K-10 is a cardioid pencil condenser microphone with detachable capsules and a transformer-coupled circuit. No alternative capsules have been made available, but likely will be in the future, as it is a simple screw-off design that lends itself easily to expansion.

K10 schematicThe amplifier circuit is built with surface-mount components. It uses the 2SK170 JFET that is common to most Chinese-made microphones.

The mics are sold in matched pairs, and ship in a padded hard-shell case with plastic mic clips.

Karma K-10All Karma mics carry a 2-year warranty.
