Peter,
No, PIP power being 3 volts or less is not enough voltage to activate
the voltage regulator circuit built into the K6 power module.
I have never tested to see what the minimum voltage required by the K6
is, I simply know the ME/K6 series mics will work with a Phantom power
of 12 volts as that is what the SD 302 Mixpre supplies when set to its
low Phantom power voltage setting. As I see no difference in the ME66
microphone performance (sensitivity and self noise in my application)
whether the Phantom power is set to 12 VDC or 48 VDC, I prefer to use 12
VDC as having worked with hi-gain audio devices and voltage regulators
in my career as an electronics design engineer, I know that when pushed
hard, electronic regulators can generate noise so it makes sense to me
to use the lower voltage which causes the regulator to operate more
efficiently and should use less power to get the job done with less
chance of generating noise.
Frankly, I see no problem in using a good grade AA alkaline battery and
do not worry about power from the recorder. One benefit in this is that
a battery in a microphone will always be electrically quieter than any
regulator in a recorder feeding voltage down a cable can ever be...
Operating the ME66/K6 on its internal battery will give you better
recorder battery life compared to using the recorder to power the
microphone. According to Sennheiser, using the K6 internal AA reduces
the mic sensitivity (gain) 3db but I don't see this myself in my
operation with SD hi-gain, low noise preamps in front of the recorder
and I prefer to use the K6 internal AA battery in place of the recorder
mic power unless I'm running a very long recording session using the
high capacity external DC power source for the recording gear. Under
those conditions, recorder/preamp/microphone battery life is no longer
an issue and Phantom power becomes practical...
