Re: Sennheiser ME-66 high frequency noise

Hi Chris,=0D

 This noise originates from the DC/DC converter of the K6 microphone module=
 that converts the low battery voltage of 1.5 V to the higher supply voltag=
e for the internal circuitry. This noise will disappear once you power the =
K6 module externally by the 48 V phantom power provided by the recorder.=0D

 I don't see a problem with that noise because it is well outside of the se=
nsitive frequency range of the microphone. So, one could simply low-pass fi=
lter the recordings in order to get rid of that noise.=0D
