in 2005, the MK-105 retains the authorative lower midrange power
Oktava is known for but adds some top end sparkle. The combination
of the new capsule, headbasket and transformerless circuit produces
a more transparent or hi-fi sound when compared to the classic
transformer output coloration and soft top end of the MK-219/319.
The large 27.5 mm capsule with precision-drilled backplate holes in
conjunction with the headbasket design produces a gentle +4dB rise
from 4 kHz to 12 kHz to lend a touch of presence and air to vocal or
Inside the headbasket, the capsule is mounted on a conical diffuser
designed to reduce standing waves and smooth the capsule /
headbasket system frequency response.
The MK-105 employs the highly regarded transformerless circuit found
in one of the most widely used mics in existence – the MK-102 (over
90,000 in use worldwide) to deliver the alluring sound of direct
phantom power applied to a large diaphragm capsule.
On-axis - A carefully crafted “double peak” high frequency response
provides subtle emphasis of both presence and “air” frequencies
while suppressing the sibilance range. This results in a more modern
or “Hi-Fi” sound when compared to the classic midrange-rich 219/319
sound but without the harsh sibilance found in many modern mics.
Off-axis - Frequency response at 90 degrees resembles 0 degree
response but attenuated a nominal l0dB. 180 degree rejection
increases to 16dB below 2kHz but the top end over 4kHz stays just
8-10 dB or so below the on-axis response. This means the MK-105 has
a very natural off-axis response out to 90 degrees with a pleasingly
bright room ambience.
The MK-105 excels where the recordist wants a large diaphragm
cardioid mic with a musically useful proximity effect, a sparkling
top end free from sibilance and a bright room ambience sound.
