Michael,

            Thanks for the response. I appreciate your explanation. I'll
look into it.

 

All the best,

 

Greg

Yes, it is counterintuitive, but there is very little proximity effect from
the microphone capsules which makes mic placement less critical than with
other types.  As the website states: 

 

"The PianoMicT System uses time coherent, omnidirectional microphones with
no proximity effect (i.e. the low frequency response will remain the same no
matter what the microphone distance is from the piano strings). The
microphones are designed for random-incidence response to obtain optimum
sonic results from the sound field inside of the piano."

 

The Earthworks engineers aren't quick to discuss proprietary details, but
the technical information of how this is possible might be found in the
patent documents. I thought I understood it when the head electrical
engineer explained it to me back in January, but electronics is not my forte
and the mental emails have long since been deleted. So any attempt by me to
explain it would be speculative and confusing at best.

Michael,

            I don't doubt you`re receiving a good recording from your set up
but it doesn't seem very logical to me. Those mics on the bar going across
look as if they would focus on the notes that they're stationed right above
and cause them to stand out quite readily. How do you prevent that?
