unbalanced inputs to the 722

["Derek Holzer" derekatumaticdotnl]

Has anyone else experienced problems using unbalanced and/or impedance
mis-matched inputs to the SD 722? Using either my homemade piezoelectric
contact mics or my new Core Sound binaurals, I get noticeable
electromagnetic interference from the hard drive writing when recording.
The only solution I've found is to use a pair of passive DI boxes to
balance the signal and convert it to a low impedance that the 722 can
handle. But the pair is just as big as my 722, which hardly makes for a
small, stealthy kit!!! If anyone else has this problem, drop me a line
and let me know how you worked around it. A reply to my inquiry from
Sound Devices is still pending.

best,
d.
