If you are looking for a small diaphragm condenser microphone that will add extra sparkle to your high end, more presence to your mids, and greater weight to your bass………… then the Oktava MK-012 is definitely not for you!! However, if you are looking for an accurate microphone which simply reproduces what it hears, then the Oktava MK-012 is definitely worth considering.
I bought a matched stereo pair about 10 years ago (direct from Oktava) and they have earned me more money than any other mics I own! I have used them on hundreds of live shows for many different purposes, including drum overheads, hi-hat, Latin percussion, grand piano, acoustic instruments, and as ambient mics. However, it is on classical music recording that they really excel. I have used them in a variety of stereo configurations and in each case they provide a clean accurate account of the performance, capturing the finest nuances of timbre and texture.
Here below are my favourite stereo microphone techniques illustrated with the Oktava Mk-012s
These microphones have not been ‘modified’ in any way and the recordings linked below have not been EQ’d or processed. Although the streaming quality is reasonably good, for more detailed listening most of the tracks can be downloaded off Soundcloud in their original full resolution wav format.
Near-coincident X-Y crossed pair at 90 degrees gives a phase-coherent stereo image with excellent positionality. The angle between the mics can be altered to suit the width of the subject and the relative distance of the mic placement. Particularly useful for chamber music and small ensembles. Cardioid or hyper-cardioid capsules can be used.
Oktava do now make a dedicated figure of eight capsule. In which case a pair of those would be another option.
N.B. The shock mounts are Rycote InVision INV-7 and (below with piggyback clips)
M-S pair using the Oktava figure of eight adapter which utilises 2 cardioid capsules back to back, in opposite phase. The Mid mic can be cardioid, hyper-cardioid or omni. As with the X-Y array, the M-S pair produce an accurate phase-coherent image. Works exceedingly well on wide subjects such as orchestras and choirs, particularly when the mic position needs to be close to the performers. Has the additional advantage that the relative levels of the mics can be manipulated in post-production. (Reducing the level of the Mid mic and raising the Side channels widens the image. Increasing the Mid and lowering the Sides ends in Mono!)
ORTF pair. Cardioid capsules set at 55 degrees and spaced 17 cm apart. Emulating the inter-aural time differences between our ears this configuration produces a detailed but somewhat more diffuse stereo image than the previous examples. This array produces a good sense of depth and perspective. Many engineers argue that ORTF pairs give a more ‘musical’ sound. (?) Excellent for choirs and orchestras.
The Jecklin Disc takes the principles of the ORTF pair one step further and introduces a foam and fur covered 12”disc between the microphone ‘ears’, emulating the reflective, and shading characteristics of the human head. This array utilises a spaced pair of omni capsules angled slightly outwards. The Jecklin disc with a pair of MK-012s produces a remarkable sense of ‘being there’. Excellent in situations where, along with the performance, you want to capture the acoustics of a great sounding hall or church. Good with subjects of any size and can be positioned at a distance without losing ‘presence’.
Some years ago whilst recording a live performance of Monteverdi Vespers, I was somewhat taken aback at the start of the concert by the following occurrence. As the choir processed in from the back of the church, they suddenly started singing!! Arrgh! With almost any other array this would have been a recording disaster. As it was, the pick-up of the Jecklin disc with its MK-012 omnis is pretty much the same from behind! The choir processed down the length of the church and filed past on either side of the mic stand and took their positions in front still singing! Sounded great!
One thing I particularly liked about my MK-012s when they arrived, was the inclusion of individual printouts of the response characteristics of each of the 6 capsules. Below is the printout comparing the matched frequency response of the 2 cardioid capsules, complete with handwritten details!
Having provided a neat wooden box it is commendable that Oktava didn’t waste money on fancy, glossy, printing on the packaging! No hype, no bullshit, no celebrity endorsements, just a great sounding pair of mics !
