OWNER'S MANUAL
Keepthis manual ina safe placeforfuture reference.
LOCATION
Avoid placing your RX-300/U in direct sunlight or
close to a source of heat. Also avoid locations in
which the device is likely to be subiected to exces-
sive dust, cold or moisture. .
VENTILATION
The openings on the cabinet ensure the ventilation
of the receiver. If these openings are obstructed, the
temperature inside the cabinet will rise rapidly and
eventually damage the circuits. Therefore, avoid
placing objects against these openings and do not
install your receiver in a place where the flow of air
through the ventilation openings could be impeded.
HANDLING
@ Power cord
When removing the power plug from the wall outlet,
always pull directly on the plug. Never yank the cord
as this may result in damage to the cord and possibly
a short-circuit.
If you do not intend to use this unit for an extended
period of time, it is advisable to unplug the power
cord.
& Switches and knobs
Avoid applying excessive force to the switches and
knobs.
& Relocation
Before moving your receiver, be sure to unplug the
power cord and remove all other connecting cables.
IN CASE OF TROUBLE
® Troubleshooting Chart
Consult the Troubleshooting Chart for advice on
common operating errors before concluding that
your receiver is faulty.
© Servicing
Do not open the cabinet or attempt to make repairs
by yourself as this may aggravate the damage and
expose you to an electrical shock. For any servicing,
refer to your YAMAHA dealer.
@ Object and liquid entry
See to it that foreign objects or spilled liquids do not
enter into the cabinet. Should this case arise, consult
your YAMAHA dealer.
CLEANING
Wipe off dust with a dry soft cloth. To remove dirt
or fingermarks, use a damp cloth then dry imme-
diately with a clean cloth. Do not use alcohol, thin-
ners or other chemical solvents since they may
damage the finish or remove the panel lettering.
Do not use any aerosol sprays near this unit as these
products can easily get into the unit and damage the
circuitry.
® Back-Up Power
The back-up power supply will keep the preset sta-
tions memorized for about one week if the power
supply fails or the set is unplugged. In order to keep
the back-up power supply fully charged when the

Manual/FM Mono sets the tuner in the manual tuning
mode, where FM Muting is inactive, allowing ex-
tremely weak stations to be received. In this mode
even stereo broadcasis will be received in mono.
This willimprove the reception quality of weak, noisy
stereo broadcasts.
@ PRESET STATION KEYS
Use these keys, together with the P1-8/P9-16 Se-
lector, to recall an AM/FM station or to store a station
in the memory. Any random selection of AM or FM
stations can be programmed using these keys.
@ TUNING KEY
When the Tuning Mode has been set to AUTO,
pressing the DOWN half of the key scans the fre-
quency band downwards until a station is encount-
ered, automatically tuning in the station
(Auto-search Tuning). Pushing the key again scans
progressively lower frequencies until the next sta-
tion isfound. Whenthe bottom ofthe bandis reached,
the frequency is set to the top of the band and the
scan continues downward. Pressing the UP half of
the key performs this by scanning the band upwards.

sponse. When this knob is set to the center defeat
position a flat response is obtained.
(> BALANCE CONTROL
This knob is used to adjust the relative volume of the
left and right channels, enabling you to compensate
for unbalance created by installation locations of the
speakers.
@ CONTINUOUS LOUDNESS CONTROL
This control provides compensation for the human
ear's loss of sensitivity to high and low frequency
ranges at low volumes. As the amount of compen-
sation required is determined by the listening level,
this control provides the most accurate compen-
sation for any listening level. Set it to the flat position
while the volume is set to your normal listening level.
Turning it counterclockwise will decrease the vol-
ume while retaining the natural balance of low and
high frequencies.

© CONNECTING THE AM ANTENNA
In many cases it will be possible to get excellent
AM reception with the supplied AM loop antenna.
Attach the antenna leads to the GND and AM ANT
terminals and clip the antenna onto its bracket, then
rotate the antenna to the best reception position.
The loop antenna may also be removed and hung
on a wall.
If necessary an outdoor antenna may be used for
improved AM reception. Connect a 5 — 10 meter
length of insulated wire to the AM ANT terminal and
run it outdoors.
2. Try changing the direction
of the loop antenna.
The loop antenna may also be |
removed and hung on the wall.
© CONNECTING THE FM ANTENNA
When connecting an FM antenna that is appropriate
to local reception conditions, consider the distance
from broadcast stations and possible interference
from surrounding tall buildings. In cases where
there are strong signals from local stations, a port-
able indoor T-type antenna is usually adequate.
Connect the feecier wire to the 3009 terminal, stretch
the wire out tight and turn to obtain optimum re-
ception. Attach to a suitable support such as a wall.
If necessary an outdoor FM antenna may be used
for improved FM reception. Either 3000 flat twin-lead
wire or coaxial cable may be used. In locations
troubled by electrical interference, coaxial cable is
preferable.
Connections for the 3000 flat twin-lead wire are the
same as for the Indoor T-type antenna. For the co-
axial cable, connect the center conductor to the left
750 terminal and the braid cable to the right 750
terminal.
NOTE: Connect either an outdoor FM antenna or an
indoor FM T-type antenna but not both.

© CONNECTING THE SPEAKERS
Connect the cords for the left speakers to the L ter-
minals and connect the right speaker cords to the
R terminals. Ensure that the polarity (+ and —)
markings are observed. Be sure to do this consist-
ently between components. If the polarity is re-
versed at either speaker the sound wili be unnatural
and lack bass. Speaker cords should be cut as short
as possible. Avoid coiling the wire on the floor or
bundling it up with cords from other system com-
ponents.
Strip about 10mm (0.39in) of insulating material from
the ends of the speaker wires and twist the exposed
strands of each end. Push in on the terminal lever,
insert the exposed wire and then pull the lever for-
ward to lock the wire into position.

© CONNECTING A TURNTABLE
Connect the output cords of the turntable to the
PHONO jacks and connect the ground wire to the
GND terminal. Normally connecting the ground wire
produces minimum hum but in some cases better
results are obtained with the ground wire discon-
nected. The turntable component and its output
cords should be positioned well away from sources
of hum such as power cords or power transformers
of other system components.
© CONNECTING A TAPE DECK
Connect the cords from the tape deck’s Line In jacks
to the Rec Out jacks, ensuring that the left and right
are not reversed. Then connect the cords from the
tape deck’s Line Out jacks to the Tape PB jacks.
@ CONNECTING TO THE CD AND VIDEO/AUX
JACKS
Connect your CD component to the CD terminals and
video component to the VIDEO/AUX terminals.
Please note that a turntable can not be connected
to these jacks as they do not provide the necessary
RIAA equalization.
© AC OUTLETS (General and Canadian models)
For added convenience the RX-300/U provides 2 AC
outlets. One "switched" outlet (the power to this
outlet is controlled by this unit's power switch) and
one "unswitched" outlet (the power to this is inde-
pendent of this unit's power switch). Be sure not to
connect appliances totaling more than 200 watts to
the unswitched outlet or more than 100 watts to the
switched outlet.
© GROUNDING
For added safety and reduced interference,
grounding is recommended. Be sure not to connect
ground wire to a water or gas pipe as this may result
in electric shock or fire.
e ABOUT THE FREQUENCY STEP SWITCH
(General Model)
Areas other than the United States, Canada and
Europe, because interstation frequency spacing is
different in different areas, please set rear panel
FREQUENCY STEP switch to agree with the station
spacing in your area (50 kHz FM/9 kHz AM or 100
kHz FM/10 kHz AM).

Multipath is an effect similar to television ghosting;
it distorts the received signal and also causes poor
stereo separation and noise. As shown below, radio
waves which travel directly from the transmitter to
the receiving antenna are mixed with waves which
reflect off nearby objects such as buildings. Because
the path taken by the reflected waves is longer than
the direct path, the time required for the waves to
arrive at the antenna is also longer. The mixing of
the directly received signal and the delayed signal
noticeably degrades reception quality. Multipath
interference can be greatly reduced by the use of a
high-quality directional antenna correctly oriented.

6 If power is turned off while a station is tuned in,
the same station will be tuned in automatically when
power is turned on again. Even if the power cord
is pulled out rather than the power key being turned
off, the effect is the same.
® When the reception band is changed from FM to
AM, the last AM station listened to will automatically
be tuned in again. In the same way, when reception
band is changed from AM to FM, the last FM station
will be tuned in again.
* |f the power is turned off or the Band selector is
pressed while auto-search tuning is in progress,
next time the power is turned on or the Band se-
lector is pressed no station may be tuned in even
though the frequency display is lit.
