more microphones placed proximately to, on or inside an
instrument. For example, the microphone can be mounted
permanently on or in the instrument, or it can be attached
temporarily to the instrument with a chip designed for the
specific instrument in question. It may also be held on a stand
when feasible and preferable. While any microphone of suitable
quality will do, a miniature microphone (and particularly when
attached to the instrument) has two advantages. First, it is
easier to accurately place, and will go in some places that a
normal microphone will not fit. Second, it will move with a
non-stationary (e.g., hand-held) instrument, and so avoid
unwanted changes of sound quality that arise when an instrument
moves relative to a microphone.
Another feature of the system is an equalizer unit that is
“tailor-made” for each type of instrument and, more particularly,
for a preselected optimum microphone location on each type of
instrument. The equalizer may include conventional low pass,
high pass, band pass, and/or notch filters, or other processors,
as appropriate. Contrary to conventional general purpose
equalizers having four or more adjustable filters, with up to
three controls for each filter (a total of twelve or more knobs),
these units may have only a minimum number and type of filters
