Oktava MK-012-01 hypercardiod microphones, matched pair, calibration protocols below - two coordinate systems, each for one mic, measurements from 20Hz to 20KHz in 0° (top), 90° (center) and 180°

  • @_jayrope the russian-language site provides diagrams in graphical form for the exact models: #^https://oktavamicrophones.ru/mk-012

    And there's a link to the techspec there too.

    If you need the data exactly in text form, as you wrote above - i think it is better to make an email enquiry: [email protected] (it's an "export" mailbox, so you can write to it in english)

    Another Oktava MK-012 omni matched pair capsules frequency diagram.

  • If i understood your request correctly: dB is labelled top left, hertz is labelled bottom right. It s 'дб' and 'гц' handwritten. Accordingly, 0dB in this diagram is the lowest limiting line.

  • By the way, i used to live not far from the Oktava factory. @_jayrope, if you will need it, i can help you to buy their microphones from the manufacturer, including those that are no longer in production.
