PARTS
USED
1.
Digital
transistors
A
digital
transistor
which
incorporates
resistors
in
its
package
is
used.
Although
its
appearance
is
similar
to
that
of
a
conven-
tional
transistor,
the
internal
circuitry
is
as
shown
below.
When
replacing
it,
pay
attention
to
the
circuitry
rather
than
the
appearance.

DESCRIPTION
Equalization
curve
Equalization
curve
preset
memory
lt
is
too
much
trouble
to
adjust
the
equalization
curve
every
time
the
type
of
music
is
changed.
For
convenience,
the
KGC-9400
has
a
preset
memory
function.
Therefore,
if
the
desired
equalization
curve
is
memorized
beforehand,
one-
touch
operation
allows
the
unit
to
be
set
to
the
sound
best
suited
for
a
particular
type
of
music.
1.
By
operating
an
equalizer
lever
for
each
frequency
band,
the
equalization
curve
is
preset.
2.
When
the
memory
switch
is
depressed,
the
memory
in-
dicator
lights
for
about
8
seconds.
3.
If
the
desired
preset
key,
1
to
4
is
depressed
while
the
memory
indicator
is
lit,
the
equalization
curve
is
stored
to
the
key.
