Recommende settings / OKM – Brief instructions

Recommended settings for OKM II K with A3 on portable recorders

SPL [dB] SP [Pa] estimated loudness Input ATT.
(Recorder)
A3 ATT
100 to 120 2 to 20 loud LINE - 20 dB
82 to 102 0,25 to 2,5 medium LINE - 0 dB
63 to 83 0,03 to 0,3 low MIC 20 dB 0 dB
43 to 63 3 to 30 very low MIC 0 dB 0 dB
  • Estimate the loudness and adjust your devices accordingly. Watch the level meter and set the desired recording level. Check the recording level control setting. If within 3…10 is ok, you can start recording.
  • If level should be low with control set to “10″ : Please choose the settings of the line below and try again. To minimize noise, approach the sound source.
  • Control settings below “3″ indicate that the sound level was underestimated and distortions due to pre-stage clipping may occur. Please choose settings of line above.

In case of very high sound levels (PA), the special version OKM II R (=Rock) is recommended. Then add 20 dB to above SPLs.
