Overview

The MK-012 is a compact, high quality capacitor microphone with interchangeable capsules to provide a choice of cardioid, hypercardioid or omni-directional polar patterns.
The wide, flat response ensures that all sounds are captured with a high degree of accuracy. A -10 dB pad is included for use in high SPL environments. The capsules, which screw onto the microphone body, utilise a precision, integral connection system to ensure reliable electrical contact.
The MK-012 is suitable for use in any situation where an accurate sound is required, the size of the system makes it ideal for use in broadcast, sound for picture, installation, sound reinforcement and theatre situations as well as the recording studio.
In pairs, the MK012s are perfectly suited for coincident and spaced stereo miking techniques, and also overhead useage in live and studio situations. Factory matched pairs can be specially ordered.
The MK-012 has following options:

MK-012
with 3 capsules

MK-012-01
with 1 capsule

MK-012-02
with 2 capsules

MK-012 mini
with mini preamp

FROM RUSSIA WITH LOVEOktava MK012 Capacitor MicrophoneSound on Sound

Oktava have created a storm in the microphone marketplace with the MK219. Now they hope to follow up their initial success with the MK012, designed for both studio and broadcast use. PAUL WHITE dons his fur hat, converts some roubles, and gives it a spin…
Oktava’s MK219 has caused quite a stir in the microphone world. It delivers a tonal performance to challenge mics which its own list price wouldn’t even pay the VAT on, despite a standard of cosmetic finish that would make a Trabant engine casting look like a work of art. In that respect, Oktava’s MK012 microphone couldn’t be more different, being well-engineered and very conservatively styled. As tends to be the case with ex-eastern bloc microphones, the technology is largely ‘borrowed’ from the major mic manufacturers, but implemented in a slightly less refined manner.
The basic package comprises the mic body plus a stand clip, a 10dB pad and three individual capsules providing cardioid, hypercardioid and omnidirectional pickup patterns. A figure-of-eight capsule might have been more useful than two cardioid types — the importers tell me they’re already looking into the possibility.
The capsules screw directly to the microphone body, where the thread-to-thread contact forms the negative signal conductor, and a central pin in the capsule mates with a sprung contact in the microphone body to carry the positive signal. If the 10dB pad is needed, it fits between the mic body and the capsule. Low noise, transformerless preamplifier circuitry is housed in the mic body, and can be driven from any nominal 48V phantom powering source. Unlike vocal mics, where the response is often deliberately coloured, the 012 has a nominally flat frequency response extending from 20Hz-20kHz — though that’s not to say that it isn’t also a good vocal mic.
I heard this mic as part of a comparative test undertaken at the Gateway School of Recording in Kingston, where they have a grand piano set up in the middle of a large studio. Several mics were set up on boom stands about four feet away from the open piano lid, and positioned as closely together as was practical. We then repaired to the control room and scrutinised the various mics while someone played the piano. Though every mic produced a slightly different sound, the 012 stood up surprisingly well, delivering a clean, open sound with plenty of depth. Further studio tests revealed tha
