MK-103 Microphones

The MK-103 is a mid-sized diaphragm microphone. It was developed to provide a microphone with a cardioid pattern and broad frequency range between Oktava's small and large diagram sizes.

The MK-103 provides a new mid-sized, 19.5 mm capsule, as one of the only mid-sized diaphragm microphones on the market today.

The MK-103 is a front address, cardioid capsule design. The MK-103 utilizes the now famous MK-012 pre-amp body. The construction of the capsule has been designed to offer maximum rear rejection.
