The AKG D12 is a passive dynamic cardioid microphone designed around a large diaphragm and an internal acoustic bass chamber to deliver extended low frequency response. It was engineered for high sound pressure level handling without the need for active electronics or external power.
The microphone employs a pressure gradient transducer and a directional cardioid characteristic intended to reduce rear pickup while maintaining a stable and consistent response across its operating range.
The AKG D12 incorporates internal elastic suspension to reduce handling noise and floor borne vibration, and features an integrated grille assembly designed to provide wind and breath noise protection.
Its mechanical construction and acoustic design made it suitable for demanding professional environments including broadcast studios, live sound systems, and instrument recording.
