Oktava MK-104
Large Diaphragm Studio Condenser Microphone
|
|
|
Overview
|
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.
