Oktava MK-103
Middle Diaphragm Studio Condenser Microphone
|
|
|
Overview
|
Released in October 2006, 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.
