been carefully
preset,
and the overall response
curve
maintains
complete linearity
from
50Hz
to above 10KHz,
unlike
the curvature in response
normally associated
with
ordinary
tone controls
Specif ically, when the control is
turned
to the
first
"up-tilt" position
it w¡ll
decrease
bass
and
increase
treble
by
15dB
at
'l
00Hz and l0KHz
respectively,
while
selection to
the second
"up-tilt"
posìtion
will
result in
a 3dB cut and boost at these same
frequencies.
Selection
of the
fìrst
"down-tìlt" position
wìlì decrease
treble and increase bass by i
5dB at
the
same reference
frequencies,
while the second
"down-tilt" position provides
3dB of
boost
(at
100H2)
and cut
(at
10KHz)
Combined
use of the LINEAR
EOUALIZEB
and
convenlional
tone
controls
provides
a degree of tonal flexibility
which
cannot
be
achieved
with
any
other
tone control arrangement
presently
available
Because
of the
inherently
linear nature
of this new
circuit, lt
introduces
no
ìncrease of
harmonic
distortion at
any
of
its
settings
