STEREO
APPLIC
ATIONS:
5.
The
value
of
the
audio
input
capacitor,
C5,
can
be
increased
to
220nF
to
improve
low
frequency
response.
6.
The
audio
signal
is
encoded
and
pre-emphasis
is
applied
in
the
bas
eband
stereo
encoder.
It
is
not
necessary
to
add
pre-emphasis
in
the
RF
modulator
and
the
pre-emph
asis
capacitor
C4
should
be
removed.
Sometimes
it
is
useful
to
increase
the
FM
deviation.
Replace
the
o
riginal
pre-emphasis
capacitor,
C4,
with
a
100-nF
capacitor.
Adding
this
kind
of
value
boosts
the
devia
tion
and
does
not
create
a
pre-emphasis.
7.
Sound
loop
filter
C6
and
C7
are
in
a
10:1
ratio,
and
should
be
changed
to
1uF
and
100nF
respectively
for
stereo
applications.
R1
should
also
be
changed
to
5.6K.
It
is
p
ossible
to
peak
the
low
audio
frequencies
(from
30
to
80
Hz)
by
adjusting
the
resistor,
R1.
A
value
of
4
.
7
K
gives
a
peak
of
about
1
dB
at
40
Hz
and
extends
the
low-frequency
cut-off
to
28
Hz.
Another
option
for
absolutly
the
BEST
stereo
performance
at
the
cost
of
slow
startup
(1-2
seconds)
is
to
use
C8
=
2.2uF.
