Oktava ORTF question
I have an Oktava MK-012 pair that I'd like to use in an ORTF setup. At the moment I only have the hypercardioid capsules, not the cardioid. It's my understanding that, generally speaking, to use hypercardioids in an ORTF-like way, spacing would remain at 17 cm but the angle would decrease from 110 degrees to 90. However, I recall reading (in this newsgroup, I think) that the hypercardioid pattern on the Oktavas is actually pretty wide - closer to cardioid. In that case, would it better to treat the Oktava hypercardioids as cardioids and start with an angle of 110? |

ORTF is just a name for a setup that works, and most cardioids aren't perfect cardioids anyway. Try it at 110 degrees. If the center of the image is weak, move them inward a bit. That's the way spaced mic setups go. You twiddle them so that they work. -- For a good time, call http://mikeriversaudio.wordpress.com |

Try it out. They will work as ORTF for sure, probably with narrowing the angle a little to give a solid centre. The determining factor will be if the solid centre gives you a sufficiently wide overall coverage for your purpose. Pulling back will include more of the sound-stage, but may not suit from a distance perspective with regarding performance versus ambience, and tonality hf drop-off. geoff |

You will find if you keep the ORTF spacing and angles that they behave very close to cardioids in that setup. But.... the ORTF spacing is a good idea but not necessarily optimal for any given room and you will likely have to fiddle with it a bit to get the stereo image the way you want it. So don't let the label on the capsule bother you any. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
