PRECAUTIONS: READ THIS BEFORE OPERATING YOUR UNIT

■ This system is equipped with the newly developed Active Servo
Processing Speaker System. It is not designed for use with
conventional speakers. Therefore, do not attempt to connect
other speakers than the provided speaker system.

■ Choose the installation location of this unit carefully. Avoid
placing it in direct sunlight or close to a source of heat. Also avoid
locations subject to vibration and excessive dust, heat, cold or
moisture. Keep it away from sources of hum such as
transformers and electric motors.

■ Do not operate this unit upside-down. It may overheat, possibly
causing damage.

■ Never open the cabinet. If something drops into the set, contact
your dealer.

■ Always set the VOLUME control to minimum before starting the
audio source: increase the volume gradually to an appropriate
level after play has started.

■ Do not use force on switches, controls or connection wires. When
moving the unit, first disconnect the power plug and the wires
connected to other equipment. Never pull the wire itself.

■ Do not attempt to clean the unit with chemical solvents; this might
damage the finish. Use a clean, dry cloth.

■ Be sure to read the “TROUBLESHOOTING” section regarding
common operating errors before concluding that the unit is faulty.

■ To prevent lightning damage, disconnect the AC power plug and
the antenna cable when there is an electrical storm.

■ Sudden temperature changes and storage or operation in an
extremely humid environment may cause condensation inside the
cabinet.
Condensation can cause the unit to malfunction.
To eliminate condensation:

CD pickup

•

Leave the power on with no disc in the unit until normal
playback is possible (about 1 hour).

Tape head

•

Leave the power on with no cassette in the unit until normal
playback is possible (about 1 hour).

Note

If condensation forms on the tape head, foreign matter may
accumulate during use.

Remote control

•

Wipe off condensation on the transmitter window with a soft
cloth before operating the unit.

IMPORTANT

Please record the serial number of this unit in the space below.
Serial No.:
The serial number is located on the rear of the unit.

Retain this Owner’s Manual in a safe place for future reference.

WARNING

TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO
NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.

■ Do not plug the AC power plug to the wall socket before you
finish all connections.

■ Never allow metallic items (e.g. screwdrivers, tools, etc.) to come
near the cassette deck’s record/playback head assembly in this
unit. Doing so may not only scratch or damage the head’s mirror­smooth finish, it may change the magnetic characteristics of the
heads, causing a deterioration in reproduction performance
quality.

■ Although the cassette deck’s record/playback heads used in this
unit are high quality heads with outstanding reproduction
characteristics, they can become dirty through the use of old
tapes or from dust accumulation over time. This can have a
serious effect on reproduction quality. Clean the heads regularly
with one of the commonly available head cleaners or with
cleaning solutions.

■ The voltage to be used must be the same as that specified on
this unit. Using this product with a higher voltage than that which
is specified is dangerous and may result in a fire or other type of
accident causing damage. YAMAHA will not be held responsible
for any damage resulting from use of this unit with a voltage other
than that which is specified.

■ The sound level at a given volume setting depends on speaker
location and other factors. Care should be taken to avoid
exposure to sudden high levels of sound, which may occur when
turning on the unit with the volume control setting at high, and to
continuous high levels of sound.

1 Remove the battery compartment cover.

(Slide the cover in the direction of the arrow.)

2 Insert 2 “AA” size batteries (UM/SUM-3, R6, HP-7 or

equivalent) into the battery compartment.
* Installing the batteries improperly may cause failure.

3 Replace the battery compartment cover.

Precautions for battery use

Insert the batteries according to the direction indicated in

•

the battery compartment.
Replace all batteries with new ones at the same time.

•

Remove the batteries if they are weak or if the unit is not

•

in use for long periods.
Don’t mix normal batteries with rechargeable batteries.

•

99.)

Proper use of the remote control
transmitter

(See figure 7 on page 99.)

Aim (within the range of 60° with no obstacles) the remote
control transmitter at the remote control sensor and operate
as shown.

Notes concerning use

Replace the batteries if control distance decreases or

•

operation becomes unstable.
Periodically clean the transmitter window on the remote

•

control transmitter and the sensor on the main unit with a
soft cloth.
Exposing the sensor on the main unit to strong light

•

(especially an inverter type of fluorescent lamp etc.) may
interfere with operation. In this case, reposition the main
unit to avoid direct lighting.
Keep the remote control transmitter away from moisture,

•

excessive heat, shock and vibrations.
The remote control transmitter’s usable range is within

•

0.2m (8”) and 6m (20’) away from the sensor.

REMOVING THE FRONT GRILLE

(See figure 8 on page 99.)

The front grille is fastened to the enclosure at four points, and
can be removed if desired. To remove the grille, first hold the
bottom of the grille and unfasten the lower part of the grille by
pulling it gently, and then hold both sides of the grille and
slowly pull straight away from the speaker. To reattach, line
up the four pegs on the inside surface of the grille with the
four corresponding holes on the speaker and push gently.

LISTENING WITH HEADPHONES

(See figure 9 on page 99.)

Be sure that your headphones have a 3.5 mm (1/8”)

•

diameter plug and are between 16 ohms and 50 ohms
impedance. Recommended impedance is 32 ohms.

Note

When the grille is removed, take care not to touch the
speaker units with your hands or to exert excessive force with
tools.

When headphones are connected, the speakers are

•

defeated automatically. Adjust the VOLUME control for
desired volume.

Never plug the AC supply lead of this system into the AC outlet until all connections are
completed.

Antenna connection

(1) Supplied FM antenna

Connect the FM antenna wire to the corresponding terminal
and direct the FM antenna wire to the direction where the
strongest signal can be received.

English

15 m (49 feet)

7.5 m (25 feet)

(2) Supplied AM (MW/LW) loop antenna

Connect the AM (MW/LW) loop antenna wires to the
corresponding terminals. Position the AM (MW/LW) loop
antenna for optimum reception. Place the AM (MW/LW) loop
antenna on a shelf etc., or install it on the rack or wall with
screws (not supplied).

Notes

When static is still heard even after adjusting the position

•

of the AM (MW/LW) loop antenna, try reversing the wire
connections (right to left).
Do not place the AM (MW/LW) loop antenna on the unit. It

•

will result in noise generation, since the unit is equipped
with digital electronics. Place the AM (MW/LW) loop
antenna away from the unit.

(3) External FM antenna

Use an external FM antenna instead of an indoor FM
antenna if you need better reception. Consult your dealer.

(4) External AM (MW/LW) antenna

Use an external AM (MW/LW) antenna if you need better
reception. Consult your dealer.

Note

When using an external AM (MW/LW) antenna, be sure to
keep the wire of the AM (MW/LW) loop antenna connected.

FREQUENCY STEP switch (General model only)

Because the interstation frequency spacing differs in
different areas, set the FREQUENCY STEP switch
(located at the rear) according to the frequency spacing in
your area. Before setting this switch, disconnect the AC
supply lead of this unit from the AC outlet.

CONNECTIONS

Speaker connection

(See figure 0 on page 99.)

Connect each speaker wire to the SPEAKERS terminals.

Cautions

Do not let the bare speaker wires touch each other as this

•

could damage the power amplifier and/or speakers.
When connecting the speakers to the unit, be sure to

•

connect the speaker wires properly. Do not make a
mistake from the right channel to the left channel and from
the plus (+) terminal to the minus (–) terminal.
Do not connect these SPEAKERS terminals to speakers

•

other than the provided speaker system NX-GX50.

TURNING THE POWER ON/OFF TO THIS SYSTEM

(See figure B on page 1100.)

If the AC supply lead is connected to the AC outlet, this
system can be turned ON and OFF (STANDBY mode) by
pressing the POWER switch on the front panel of the main
unit or the POWER switch on the remote control transmitter.

Automatic power-off function

The power of this system will be automatically turned off if
there is no operation on the control parts of this system, no
illumination on the graphic equalizer indicators and no
playback of CD or tape for about 30 minutes.

Connecting the AC supply lead

(See figure A on page

After connecting the speakers, plug the AC supply lead

•

into a convenient AC outlet.
Unplug the AC supply lead from the AC outlet if the unit is

•

not to be used for a long period of time.

STANDBY mode

While the power is on, pressing the POWER switch (or the
POWER switch on the remote control transmitter) switches
the system to the STANDBY mode. (In this mode, the
display shows only the time.) In this mode, main voltage is
still present inside the system. If you want to switch off the
system completely, disconnect the AC power plug from the
AC outlet.

SETTING THE CLOCK

(See figure C on page 1100.)

1 While the power is on, press the DISPLAY button to

display the time. If the power is off, you can proceed to the
next step.

2 While holding the TIME ADJ button pressed, press the

HOUR button and set the hour.
* Press the HOUR button once to advance the time by 1

hour. Press and hold to advance continuously.

* To reverse the hour, press the button instead of

the HOUR button.

3 While holding the TIME ADJ button pressed, press the

MIN button and set the minute.
* Press the MIN button once to advance the time by 1

minute. Press and hold to advance continuously.

* The hour setting will not advance even if minute is

* To reverse the minute, press the button instead of

the MIN button.

Europe, U.K., Australia and Singapore models use a 24­hour display. U.S.A. and Canada models use a 12-hour
display shown by “AM (PM) 00:00”. For General model,
either the 24-hour display or the 12-hour display is
selected depending on the setting of the FREQUENCY
STEP switch on the rear panel, so you cannot select a
desired type freely.

In the event of a power failure or when the AC supply
lead is disconnected.

The time display will go out, however, the clock will function
for about 5 minutes without power supply. So you do not
have to reset the time if the AC power supply is resumed
within about 5 minutes.
When the AC power supply is resumed after more than 5
minutes pass without power supply, the time display will flash
on and off to indicate that the time must be reset.
