KA-C12
Large Diaphragm Tube Condenser Microphone
The Kiwara KA-C12 is a handcrafted tube condenser that follows the legendary C12, blending classic design with modern build quality for a warm, clear and detailed sound.
A CK12 capsule and T14/1 output transformer sit at its core, paired with an EH6072A tube, cardioid, omnidirectional and figure-8 patterns and a custom power supply. Shock mount and wooden case are included.
Handcrafted With Premium Components
Assembled by hand using premium parts, including Vishay resistors and capacitors, for consistent quality and performance.
Authentic Sound
Warmth and clarity in the spirit of the C12 come from matching its core components: the CK12 capsule and the T14/1 output transformer.
Swivel Stand-Mount Connector
The microphone ships with a high-definition tube cable that ends in a 7-pin XLR at the power supply and a swivel stand-mount connector at the microphone, as on the original.
Power and Performance
A custom power supply is included so the KA-C12 delivers reliable, top-notch performance from the first session.
