Oktava MK-104

Large Diaphragm Studio Condenser Microphone



Buy original Oktava MK-104


Released in November, 2006 the MK-104 is the newest addition to the Oktava line. It features a completely new 27 mm large diaphragm capsule installed in a new acoustically optimized headbasket.

The Capsule

The new capsule is the result of ongoing research and showcases a new arrangement and sizing of precision-drilled backplate holes for optimum time and frequency domain performance. This stunning new capsule is bright, clear and accurate without being screechy, sizzly, spitty or scooped.

Headbasket and Body

The MK-104 offers a groundbreaking headbasket design. It features four acoustically optimized vents that dramatically reduce reflections within the headbasket to smooth the upper midrange response and improve transient response detail. The MK-104 is capable of rendering high frequency transients sounds with accuracy and detail reminiscent of a small diaphragm mic – but offers the flattering qualities of a large diaphragm condenser.

The Circuit

The MK-104 uses the same circuit found in the renowned MK-012 (over 90,000 in use worldwide) to deliver the alluring sound of direct phantom power applied to a large diaphragm capsule.

The Sound

On-axis - the MK-104 exhibits a smooth and gentle upward tilt from bass to treble giving it several dB more treble output relative to the bass end. Off-axis - The MK-104 has a unique and useful polar response - 180 degree output above 7 kHz exceeds 90 output. This means the MK-104 hears ambient room presence and “air” while rejecting HF bleed from adjacent sound sources.

The MK-104 excels where the recordist wants an accurate on-axis large diaphragm cardioid sound, excellent transient response and bright room ambience while minimizing HF leakage from adjacent instruments.
