Oktava Test Graphs

Frequency Response Traces Measured in Anechoic Conditions

The following frequency response plots were produced by Mark Lesonsky at Location Sound Corp. using their anechoic chamber and frequency plotter. The microphone selected for the tests was brand new; it had never before been used or even present on a set. The protocol for these tests is to align the 1 kHz response at 0db and plot the deviation above and below that point. Any plotted point above or below 0 db represents a departure from flat response. These graphs all show response within about 3db of the 1 kHz level from 100 Hz to 20 kHz. Mark and I were both impressed at the performance. The smooth and even response compares favorably with more expensive microphones.

Above we see the MCO12 Oktava mike with the hyper-cardioid capsule mounted. The results are very flat. The variance from 0 db is, at most, 2.5 db at the low frequencies and not more than 1 db at 10 kHz. And, in both cases, the variance represents a rise in response, not a loss.
