2.PRODUCT SAFETY NOTICE
Many
electrical
and
mechanical
parts
in
the
appliance
have
special
safety
related
characteristics.
These
are
often
not
evident
from
visual
inspection
nor
the
protection
afforded
by
them
necessarily
can
be
obtained
by
using
replacement
components
rated
for
voltage,
wattage,
etc.
Replacement
parts
which
have
these
special
safety
charac-
teristics
are
identified
in
this
Service
Manual.
Electrical
components
having
such
features
are
identified
by
marking
with
aA
on
the
schematics
and
on
the
parts
list
in
this
Service
Manual.
The
use
of
a
substitute
replacement
component
which
dose
not
have
the
same
safety
characteristics
as
the
PIONEER
recommended
replacement
one,
shown
in
the
parts
list
in
this
Service
Manual,
may
create

When this switch is pressed, power is supplied to the unit.
Press the switch again to turn power off.
(2) SPEAKERS switches (MLOFF, mON)
These are used to select the speaker through which you wish
to listen.
A: When the speakers connected to A terminals are in use.
B:
When
the

are
in

© Tur both A and B speakers to OFF position when only the
HEADPHONES are inuse.
NOTE: (SX-1300 only)
No sound will be heard through the speakers when both A
and B switches are depressed if only one set of speakers has
been connected to either A or B SPEAKERS terminals.
@) SURROUND selector switch (SX-2300 only)
By pressing the A and B SPEAKERS switches, then pressing
this switch ON, you can obtain surround reproduction. If you
Press this switch OFF again, normal reproduction from both
speakers A and B will be obtained.

@) FM MODE AUTO/MONO selector switch
Use to select the auto stereo mode or monaural mode when
listening to FM broadcasts. The monaural mode has been
selected when the FM MONDO indicator is lighted.
Auto stereo mode:
Normally leave in this mode for reception. When a stereo FM
broadcast is received, it will be automatically reproduced in
stereo sound.
Monaural mode:
When receiving distant stations or stations with weak broad-
Cast signals, the input signal may be weak, thus resulting in
increased noise during FM stereo broadcasts. In this event,
setting the receiver to the monaural mode will reduce the
noise. In this case, however, FM stereo broadcasts will be
reproduced in monaural sound.
NOTE:
This switch has no effect on reception of AM broadcasts.
TUNING AUTO/MANUAL switch
Works during FM reception.
Use
this
switch
to
select
either
the
AUTO
mode
or
the
MANUAL
mode.
When
the
‘’AUTO”’
indicator
is
lit,
the
receiver
is

(@) MEMORY switch
This is used to memorize stations. When the switch is
pressed, the frequency indicator will flash. To memoize the
frequency of any station, press the STATION CALLs witch
while the frequency indicator is flashing.
STATION CALL switches
These switches are used to preset and recall desiredb road-
casting stations.

@) TUNING switches (DOWN, UP)
UP: The FM or AM band is scanned in the direction of increas-
ing frequency.
DOWN: The opposite operation to that of the UP switch
takes place.

1, RESISTORS:
Indicated in 2, %W, /eW,+5% tolerance unless otherwise noted k :kQ,
M : MQ, (F) : £1%, (G) : £2%, (K) :+10% (M); £20% tolerance
2. CAPACITORS:
Indicated in capacity (uF)/voltage (V) unless otherwise noted p : pF
Indication without voltage is 50V except electrolytic capacitor.
3. VOLTAGE, CURRENT:
S_] : OC voltage (V) at no input signal
Value in( —_) is OC voltage at rated power.
<5 mA: DC current at no input signal
4. OTHERS:
mp : Signal route.
@ : Adjusting point.
The mark found on some component parts indicates the im-
portance of the safety factor of the part. Therefore, when replacing,
be sure to use parts of identical designation.
> marked capacitors and resistors have parts numbers.
This is the basic schematic diagram, but the actual circuit may vary
due to improvements in design.

* Connect the FM signal generator (FM SG) to the FM ANTENNA 3002 terminal through a 3000 dummy antenna.
* Set the SX—2300 or SX—1300 to the FM band.
(*1) Tune the FM SG to the SX—2300/KUC or SX—1300/KUC.
(#2) Connect the FM multiplex stereo signal generator to the FM SG external modulator terminal. Set the modula-
tion to Main 1 kHz/L+R/+68.25kHz deviation. Pilot 19kHz/+6.75kHz deviation.

AM TUNER SECTION
MW Tuner Section
* Connect the furnished AM loop antenna between terminals AM ANTENNA and GND.
* Connect the AM signal generator (AM SG) to the AM ANTENNA terminal through a 10kf resistor.
* Set the SX—2300 or SX—1300 to the AM(MW) band.
(*3) There are 2 kinds of models in the SX—2300/SD and SX—1300/SD systems.The one is the channel step fre-
quency of 10kHz and the other is 9kHz. Accordingly, in case of model 10kHz step, the adjustment should be per-
formed by using the frequency of Item “10kHz step” and in case of model 9kHz step, the adjustment should be
performed by using the frequency of Item “9kHz step”.
