1.SAFETY PRECAUTIONS
The following check should be performed for the con-
tinued protection of the customer and service technician.
LEAKAGE CURRENT CHECK
Measure leakage current to a known earth ground (water
pipe, conduit, etc.) by connecting a teakage current tester
such as Simpson Model 229-2 or equivalent between the
earth ground and all exposed metal parts of the appliance
(input/output terminals, screwheads, metal overlays, con-
trol shaft, etc.). Plug the AC line cord of the appliance
directly into a 120V AC 60Hz outlet and turn the AC
power switch on. Any current measured must not exceed
0.5mA.

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 af-
forded by them necessarily can be obtained by using re-
placement components rated for voltage, wattage, etc. Re-
placement parts which have these special safety charac-
teristics are identified in this Service Manual.
Electrical components having such features are identified
by marking with a A\ on the schematics and on the parts
list in this Service Manual.
The use of a substitute replacement component which
does not have the same safety characteristics as the
PIONEER recommended replacement one, shown in the
parts list in this Service Manual, may create shock, fire, or
other hazards.
Product Safety is continuously under review and new
instructions are issued from time to time. For the latest
information, always consult the current PIONEER Serv-
ice Manual. A subscription to, or additional copies of,
PIONEER Service Manual may be obtained at a nominal
charge from PIONEER.

3. CONNECTION DIAGRAM
¢ ANTENNA CONNECTIONS
RADIO RECEPTION IS NOT POSSIBLE UNLESS
THE ANTENNA IS PROPERLY CONNECTED.
The strength of broadcast signal varies from one area to
another (signal propagation is especially poor in metropolitan
areas, where there are may tall buildings, and in mountainous
areas). Proper antenna installation is vital to good reception.
AM ANTENNA
The AM loop antenna supplied with the cassette deck receiver
should be connected to the AM antenna terminals. The
antenna should be placed at a distance from the cassette deck
receiver, and should not be allowed to touch metallic objects.
Avoid placing it near CD players, personal computers, televi-
sion sets, and other devices generating radio frequencies.
Setting up the AM antenna
¢ Fold out the supports on the bottom of the antenna. Insert
the stopper in the hole in the antenna to lock them in place.
* Place theantenna on a level surface and rotate it to locate
the orientation that yields the best reception.
AM Loop Antenna Set-up Hole
Stopper
AM Loop Antenna Connection
The accessory AM loop antenna must be connected to ensure
proper reception.
External AM antenna
Indoor AM antenna
Provide a vinyl-coated wire (5 to 6 meters long). Secure one
end to the AM terminal and the other end to a wall or other
high location.
Outdoor AM antenna
If receptionis still poor even when a lead antenna has been
stretched out indoors, stretch out a vinyl-coated wire and se-
cure it outdoors.
Connecting the external AM antenna
Outdoor AM antenna
Indoor AM antenna
NOTE:
Do not detach the AM loop antenna when using the external AM
antenna.
FM ANTENNA
FM T-type antenna attachment
Connect the accessory FM T-type antenna to the FM termi-
nals. Stretch the antenna out to its full length, and affix it to
a wall, etc.
Stretch out both ends.
Toth ee.
Correct Wrong Wrong
The accessory FM T-type antenna must be connect to ensure
proper reception.
External FM antenna installation
Use an external antenna when the signals from the station are
weak and cannot be picked up by the accessory FM T-type
antenna, or when the sound heard is accompanied by large
amounts of noise. There are two ways of connecting the
external FM antenna to the ANTENNA terminals with 3000
feeder wire, or with a 752 coaxial cable.
itis recommended that you use the 752 coaxial cable, so that
the effects of extraneous noise are reduced to a minimum.
When the connecting cable
is a 752 coaxial cable
75Q coaxial cable
When the connecting
cable is a 3000

° CONNECTIONS
Proceed as follows with the set-up and connections
Connect the FM antenna and the AM antenna to the cassette deck receiver's ANTENNA terminals. (See page 4)
(Use an antenna ground as necessary. See page 6.)
. Connect the turntable’s cords to the cassette deck receiver's TURNTABLE jacks (and GND terminal). If any other stereo component is
to be used, connect in the same way to the cassette deck receiver's input jacks.
. Connect the speaker cords to the SPEAKERS terminals.
. Finally, connect the power cord to the AC wall socket. * RX-1180 is not equipped with GND terminal.

Antenna ground
Although grounding is not necessary for reception it is recom-
mended for protection against damage from lightning if an out-
door FM antenna is used. Grounding is recommended as well
to help reduce noise and hum.
NOTE:
Never make the ground connection to a gas pipe as sparks could
cause the gas to ignite.
NOTE ABOUT SPEAKER CONNECTIONS
© Speaker systems used should have an impedance of be-
tween 82 and 162.
¢ Be sure that connections are secure. Check to make sure
that wires do not protrude from their terminals.
¢ Do notallow the speaker cords to become shorted.
Damage may result to your equipment.
To control a unit other than this receiver using the re-
mote control unit
@® In the case of a PIONEER equipment marked 8] which is
provided with a remote sensor, operate the equipment by
aiming the remote control unit at the remote sensor on the
equipment.
@ For equipment with the Fal mark, but without a remote
sensor, operation of the equipment by facing the remote con-
trol unittowards the remote sensor of the cassette deck receiv-
er possible with connection from the CONTROL OUT jack to
the CONTROL IN jack. Use a commercially available cable with
mini-plugs for the connection.

© Do not attempt to simultaneously connect two sets of
speakers to a single side (A or B). When using two sets of
speakers, connect one set to side A and one set to side B.
AC OUTLET
SWITCHED 100W MAX
Power supplied through this outlet is turned on and off by this
equipment’s POWER switch. Total electrical power consump-
tion of connected equipment should not exceed 100 W.
NOTE:
Do not connect appliances with high power consumption such
as heaters, irons, or television sets to the AC OUTLET, inorder
to avoid overheating or fire risk.
This can cause this equipment to malfunction.

()POWER
(STANDBY/ON)
switch
When this switch is set to the ON position, the STAND-
BY/SLEEP indicator goes out and power is supplied to the main
circuits of the cassette deck receiver.
Disconnect the power cord from the power outlet when you
do not plan to use the cassette deck receiver for a long period
of time.
The cassette deck receiver has a backup function, so it will return
to the original status when the power cord is unplugged and soon
again plugged into the power outlet.
4) STANDBY/SLEEP indicator
This indicator lights in stand-by status or when the SLEEP
function is operating when the power cord is connected to a
power outlet.
When the SLEEP key on the remote control unit is pressed,
the sleep function activated for approximately 60 minutes,
then enters the standby mode. (The SLEEP indicator flashes
faster as the end of the remaining time nears.)

¢ GRAPHIC EQUALIZER
CONTROLS
The advantage of the GRAPHIC EQUALIZER over conventional
tone controls is that with the five controls of the GRAPHIC
EQUALIZER it is possible to control five different narrow. With
conventional tone controls a setting for a bass or treble boost or cut
will also affect the lower or upper mid frequencies. The frequency
bands controlled by the five slide controls have been chosen to yield
the maximum possible control action within the audio spectrum.
100 Hz: The 100 Hz control is very useful for enhancing
low bass notes as in organ music.
330 Hz: The 330 Hz control will allow you to vary the
upper bass frequencies.
1 kHz: The 1 kHz control is the presence control and can
be used very effectively to emphasize, or de-
emphasize vocalists.
3.3 kHz: The 3.3 kHz control will add brilliance and clarity
to brass instruments and violins.
10 kHz: The 10 kHz control can be used to make up for
missing high frequencies absorbed by the environ-
ment and to add a natural crispness to music.
