Problem with that, Kevin, is the pick-up elements need to be as close
together as possible to avoid phase cancellation...particularly in the
higher frequencies. With the normal piggy-back mount we use for the
MKH30/40 combo, the elements are set at less than an inch from each
other.
The loss at the high end due to phase cancellation is measurable above
17kHz. which also happens to approach the upper limits of the mic system
so
that is not a particular problem. If they're placed further apart that
that, real (and noticable) problems will ensue.
Every system has it's drawbacks and I should point out that this is one
of
the main critiques with this type of system.
All best,
Bernie
