case
of
this
unit,

resistor
with
characteristic
(C)
which
is
short-circuited
between
its
ends
at
rotational

angle
of
150°
(center)
is
used
for
bass
adjustment.
Also,
variable
resistor
with
characteristic
(C)
whose
resistance
is
zero
at
rotational
angle
of
150°
(center)
is used
for treble adjustment.
