The MK-103 is a mid-sized diaphragm mic developed to compliment Oktava small and large diaphragm condenser mics. It provides a useful gradation in time domain response between the small and large diagram sizes and offers excellent cardioid pattern attenuation over a broad frequency range.

  • The Capsule
  • The MK-103 features a newly-developed mid-sized 19.5 mm capsule with quick transient response reminiscent of the acclaimed MK-012 small diaphragm mic but retains some of the magic associated with Oktava’s large diaphragm capsules. 

  • The Headbasket & Body

  • The MK-103 feature a front address head assembly coupled to smaller diameter, in-line body that eliminates a source of reflection between sound source and capsule. The tight fitting headbasket surrounds the capsule closely to eliminate another source of sound reflections. Finally, the headbasket has been acoustically designed as an optimally-curved housing that eliminates sharp edge refractions that can color the pure sound of the capsule. 

  • The Circuit

  • The MK-103 uses the acclaimed transformerless circuit field-proven in the popular MK-012 (over 90,000 in use worldwide) to deliver clear and uncolored sound. 

  • The Sound

  • On Axis – Quick transient response and extended high frequency response are hallmarks of the MK-103. Off Axis –Moderately strong attenuation at 90 degrees creates a tightly focused cardioid pattern while very strong midrange attenuation at 180 degrees minimizes room sound and unwanted sound source pick up. The MK-103 excels where the recordist wants fast transient response, extended high end and strong attenuation of ambient room sound.
