PRECAUTIONS: READ THIS BEFORE OPERATING YOUR UNIT

■ This system is designed for using the provided

Active Servo Processing Speaker System for front
speakers. Therefore, do not attempt to connect

other conventional speakers to the FRONT
SPEAKERS terminals of this 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 an audio source play: 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.

■ Do not plug the AC power plug to the wall socket

before you finish all connections.

■ 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 unit 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.

■ 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 tape 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.

■ 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.

Dolby Pro Logic Surround

This unit employs a Dolby Pro Logic Surround decoder similar
to professional Dolby Stereo decoders used in many movie
theaters. By using the Dolby Pro Logic Surround decoder,
you can experience the dramatic realism and impact of Dolby
Surround movie theater sound in your own home. Dolby Pro
Logic employs a four channel five speaker system. The Pro
Logic Surround system divides the input signal into four
levels: the left and right main channels, the center channel
(used for dialog), and the rear surround sound channels
(used for sound effects, background noise, and other ambient
noises). The center channel allows listeners seated in even
less-than-ideal positions to hear the dialog originating from
the action on the screen while experiencing good stereo
imaging.

Dolby Surround is encoded on the sound track of pre­recorded video tapes, laser discs, and some TV/cable
broadcasts. When you play a source encoded with Dolby
Surround on this unit, the Dolby Pro Logic Surround decoder
decodes the signal and distributes the surround-sound
effects.
In addition, this unit features a built-in automatic input balance
control. This always assures you the best performance
without manual adjustment.

•

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.

SETTING UP THE MAIN UNIT

Setup examples

Main unit

Place the main unit as illustrated on the left and allow spaces
more than indicated around the main unit and more than 10
cm (3-15/16”) behind the main unit to assure good
ventilation. Be sure not to place another unit or any object on
top of the main unit to prevent the ventilation holes on the top
panel of the main unit from being obstructed. Otherwise, it
may cause fire or damage to the main unit.

Notes

When placing the front speakers apart from the main unit,

•

allow a space of at least 10 cm (3-15/16”) above, behind
and on the both sides of the main unit.
If the main unit is put in a rack, the front of it must be fully

•

opened.
Disconnect the AC supply lead from the AC outlet before

•

connecting or disconnecting any component.

This system is designed to provide the best sound-field quality with a 5 speaker configuration: front speakers, rear speakers and a
center speaker. You may omit the center speaker, if for some reason it is not practical to use a center speaker. (Refer to the “4-
Speaker Configuration” shown below.)
The front speakers are used for the main source sound plus the effect sounds. The rear speakers are used for the effect and
surround sounds, and the center speaker is for the center sounds (dialog etc.).

Speaker configuration

(1)

(1)5-Speaker Configuration

This configuration is the most effective and recommended
one. In this configuration, the center speaker is
necessary as well as the rear speakers. If the sound field
program DOLBY PRO LOGIC or DOLBY 3 STEREO is
selected, conversations will be output from the center
speaker and the ambience will be excellent.

● Set the center channel mode to the “NORMAL”

position. (For details, refer to page 15.)

English

(2)

Front L

Center

Front R

(2)4-Speaker Configuration

The center speaker is not used in this configuration. If the
sound field program DOLBY PRO LOGIC is selected, the
center sound is output from the left and the right front
speakers, although the program DOLBY 3 STEREO is
useless in this configuration. However, the sound effect
of other programs can be the same as that of the 5­speaker configuration.

● Be sure to set the center channel mode to the

“PHANTOM” position. (For details, refer to page 15.)

Note

Be sure to use two rear speakers. If you connect one rear
speaker only, sound will not be output from the rear speaker.

Speaker placement

Front speakers: In normal position.
Rear speakers: Behind your listening position, facing

slightly inward. Nearly six feet (approx.

1.8 m) up from the floor.

Center speaker: Precisely between the front speakers.

■ Mounting the rear speakers

Mount the rear speakers on a shelf, rack or on the floor
directly, or hang them on the wall.

To mount the rear speakers on a wall

1 Attach the provided mounting bracket to the rear of the

speaker by using the provided screws.

2 Fasten screws into a firm wall or wall support as shown in

the diagram, and hang the holes of the mounting bracket
on the protruding screws.
* The holes are arranged so that the speakers can be

mounted in a side long, upright or upside-down way.

* Make sure that the screws are caught by a narrow part

of the holes securely.

Notes

●

Never attach the bracket to the speaker conversely.

Tapping screw
(Available at the
hardware store)

Good No good

●

Speaker cords should be connected to the speaker’s
terminals after the bracket has attached to the speaker to
prevent the speaker cords pressed between the speaker
and the bracket.

To hang in a side long way

Hang the speakers so that each of them faces inside as
figured left.

WARNING:

● Each speaker weighs 0.8 kg (1 lbs. 12 oz.). Do not

mount them on thin plywood or soft wall surface
material, as the screws may come out of the flimsy
surface, causing the speakers to fall down and be
damaged, or result in personal injury.

● Do not fasten the speakers to wall with nails,

adhesives, or other unsound hardware. Long-term use
and vibrations may cause them to fall down.

● To avoid accidents resulting from tripping over loose

speaker cables, fix them to the wall.
