PREPARATIONS

PRECAUTIONS

Read the Operating Instructions carefully and completely before
operating the unit. Be sure to keep the Operating Instructions
for future reference. All warnings and cautions in the Operating
Instructions and on the unit should be strictly followed, as well
as the safety suggestions below.

Installation

1 Water and moisture — Do not use this unit near water, such

as near a bathtub, washbowl, swimming pool, or the like.

2 Heat — Do not use this unit near sources of heat, including

heating vents, stoves, or other appliances that generate heat.
It also should not be placed in temperatures less than 5°C
(41°F) or greater than 35°C (95°F).

3 Mounting surface — Place the unit on a flat, even surface.
4 Ventilation — The unit should be situated with adequate

space around it so that proper heat ventilation is assured.
Allow 10 cm (4 in.) clearance from the rear and the top of the
unit, and 5 cm (2 in.) from each side.

- Do not place the unit on a bed, rug, or similar surface that
may block the ventilation openings.

- Do not install the unit in a bookcase, cabinet, or airtight rack
where ventilation may be impeded.

5 Objects and liquid entry — Take care that objects or liquids

do not get inside the unit through the ventilation openings.

6 Carts and stands — When

placed or mounted on a stand
or cart, the unit should be moved
with care.
Quick stops, excessive force,
and uneven surfaces may cause
the unit or cart to overturn or fall.

7 Condensation — Moisture may form on the CD pickup lens

when:

- The unit is moved from a cold spot to a warm spot

- The heating system has just been turned on

- The unit is used in a very humid room

- The unit is cooled by an air conditioner

When this unit has condensation inside, it may not function
normally. Should this occur, leave the unit for a few hours,
then try to operate again.

8 Wall or ceiling mounting — The unit should not be mounted

on a wall or ceiling, unless specified in the Operating
Instructions.

Electric Power

1 Power sources — Connect this unit only to power sources

specified in the Operating Instructions, and as marked on the
unit.

2 Polarization — As a safety feature, some units are equipped

with polarized AC power plugs which can only be inserted
one way into a power outlet. If it is difficult or impossible to
insert the AC power plug into an outlet, turn the plug over and
try again. If it still does not easily insert into the outlet, please
call a qualified service technician to service or replace the
outlet. To avoid defeating the safety feature of the polarized
plug, do not force it into a power outlet.

3 AC power cord

- When disconnecting the AC power cord, pull it out by the
AC power plug. Do not pull the cord itself.

- Never handle the AC power plug with wet hands, as this
could result in fire or shock.

- Power cords should be routed to avoid being severely bent,
pinched, or walked upon. Pay particular attention to the cord
from the unit to the power socket.

- Avoid overloading AC power plugs and extension cords
beyond their capacity, as this could result in fire or shock.

4 Extension cord — To help prevent electric shock, do not use

a polarized AC power plug with an extension cord, receptacle,
or other outlet unless the polarized plug can be completely
inserted to prevent exposure of the blades of the plug.

5 When not in use — Unplug the AC power cord from the AC

power plug if the unit will not be used for several months or
more. When the cord is plugged in, a small amount of current
continues to flow to the unit, even when the power is turned
off.

Outdoor Antenna

1 Power lines — When connecting an outdoor antenna, make

sure it is located away from power lines.

2 Outdoor antenna grounding — Be sure the antenna system

is properly grounded to provide protection against unexpected
voltage surges or static electricity build-up. Article 810 of the
National Electrical Code, ANSI/NFPA 70, provides information
on proper grounding of the mast, supporting structure, and
the lead-in wire to the antenna discharge unit, as well as the
size of the grounding unit, connection to grounding terminals,
and requirements for grounding terminals themselves.

Maintenance

Clean the unit only as recommended in the Operating
Instructions.

Damage Requiring Service

Have the units serviced by a qualified service technician if:

- The AC power cord or plug has been damaged

- Foreign objects or liquid have gotten inside the unit

- The unit has been exposed to rain or water

- The unit does not seem to operate normally

- The unit exhibits a marked change in performance

- The unit has been dropped, or the cabinet has been damaged
DO NOT ATTEMPT TO SERVICE THE UNIT YOURSELF.

DOLBY PRO LOGIC

The DOLBY PRO LOGIC feature and the center and rear
speakers (standard) assure full-scale home theater sound. When
playing back laser discs or video software that have been
specially recorded with four-channel sound (left, right, center,
rear) and steering logic (for sound directionality), astonishingly
realistic sound surrounds the listener to create a new level of
audio/visual entertainment.
Independent control of the four sound channels allows the listener
to enjoy the same type of sound reproduction experienced in
movie theaters. Voices are reproduced in the front and center
sound field, while ambient sounds like cars and crowds are
reproduced on all sides of the listener for an incredibly lifelike
audio/video experience. Please read the following carefully to
“tune” the system’s output to match the characteristics of your
listening space.

Check the following:

• Before using the DOLBY PRO LOGIC, adjust the proper
balance of speaker sound levels.

• Make sure the supplied speakers are properly connected and
positioned. (See page 4)

• Make sure the TV set and video unit are properly connected.
(See page 24)

• Make sure the laser disc, video tape, etc., support

.

ADJUSTING SPEAKER LEVEL BALANCE

4

If the surround speakers volume of the DSP is changed, the
DOLBY PRO LOGIC level is also changed.

About the channels

The left and right speakers create the stereo effect.
The center speaker helps achieve precise sound positioning

over a broad sound field.
The rear-mounted surround speakers enhance the “depth” of
the sound field.

To change the delay time

The surround speakers reproduce sounds a split second after
the front speakers. The delay is initially set to 20 ms
(milliseconds).
To change this standard delay time, press the MANUAL SELECT
(TEST) button on the remote control three times in NORMAL
mode (or twice in PHANTOM mode) so that “TIME” is displayed.
Then, press the f DOWN or UP g button. Each time one
of the buttons is pressed, the delay time changes as shown below.

Adjust the sound level of the center and the
surround speakers.

While “CEN” or “SUR” is displayed, press the f DOWN or
UP g button to adjust the volume of the center or surround
speakers to match the level of the left and right speakers.
To adjust the balance between the left and right speakers,
use the BALANCE control while “L” or “R” is displayed.

Press the MANUAL SELECT (TEST) button again
to stop the noise signal.

The unit is equipped with a built-in test signal generator called a
noise sequencer for easy balance adjustment of all four channels.
The sequencer outputs a noise signal that “travels” from channel
to channel, enabling the simple adjustment of sound level to
achieve, at the listening position, the same apparent loudness
from each channel.

Preparation

Balance the left and right speakers (page 7) before step 1 below.

Use the remote control.

1

Press the DOLBY PRO LOGIC button to select
NORMAL.

If PHANTOM or 3CH LOGIC appears, press the DOLBY PRO
LOGIC button repeatedly until NORMAL is selected.

To change the sound levels after adjusting the balance
with the noise sequencer

The sound levels of the center or surround speakers can be
adjusted during playback of laser discs or video software.
1 Press the MANUAL SELECT (TEST) button on the remote

control once or twice to select “CEN” (center) or “SUR”

• Is the other speaker disconnected?

The output sound is not stereo.

• Is the Karaoke function turned on? (➞ page 19)

The sound is not heard from the center or surround
speakers.

• The center speaker sounds only when the DOLBY PRO LOGIC
is activated. (➞ page 21)

• The surround speakers sound only when the DOLBY PRO
LOGIC or DSP surround is activated. (➞ page 21 or 8)

An erroneous display or a malfunction occurs.

➞ Reset the unit as stated below.

TUNER SECTION
There is constant, wave-like static.

• Is the antenna connected properly? (➞ page 4)

• Is the signal weak?

➞ Connect an outdoor antenna.

The reception contains noise interferences or the sound
is distorted.

• Is the system picking up external noise or multipath distortion?

➞ Change the orientation of the antenna.
➞ Move the unit away from other electrical appliances.

After cleaning the heads and tape paths with a liquid head
cleaning cassette or a moistened swab, wait until the cleaned
parts are completely dry before inserting the tapes.

To demagnetize the heads

The heads may become magnetized after long-term use. This
may narrow the output range of recorded tapes and increase
noise. After 20 to 30 hours use, demagnetize the heads with
any commercially available demagnetizer.

Care of discs

• When a disc becomes dirty, wipe the disc from the center out
with a cleaning cloth.

• After playing a disc, store the disc in its case. Do not leave the
disc in places that are hot or humid.

Care of tapes

• Store tapes in their cases after use.

• Do not leave tapes near magnets, motors, television sets, or

any source of magnetism. This will downgrade the sound quality
and cause noise.

• Do not expose tapes to direct sunlight, or leave them in a car
parked in direct sunlight.
