SURROUND EFFECT AND DOLBY 3CH LOGIC
This unit has a built-in surround processor for adding
presence and an expansive effect to the sound.
STUDIO:
Select this position to enjoy the effect of listening to
music in a recording studio.
The source sound is output as it is through the front
speakers, with reverberation output through the rear
speakers,
This is particularly suitable for a source that has a Jot of
reverberation.
SIMULATED SURROUND:
The “SIMULATED SURROUND” creates effects of rever-
berated and reflected sound from the walls and ceiling
similar to a concert hall. These sound-effects added to
the actual sound from the source make you feel as if you
were in a more expanded space. The different ranges of
the expanded space can be set by the DELAY TIME
button.
Set the Delay Time to 15 ms or 20 ms for a live-house
concert. For chamber music, set to 20 ms. For orchestral
music, set to 30 ms. The “SIMULATED SURROUND” aiso
gives effects on monaural sources by outputting the
reverberated sound from rear speakers while keeping
the output sound from front speakers as it is. Turn on the
“SIMULATED SURROUND” for a monaural source to
gain effective surround playback.
DOLBY 3CH LOGIC:
Combining the rear speaker signal with that of the front
speakers results in your being able to enjoy a regenerat-
ed sound field which has comparatively more presence
and a more expansive feeling from the front 3 channels
(front L, front R, and center speakers) than that of ordi-
nary stereo regeneration.
DOLBY* PRO LOGIC SURROUND:
Choose this setting for movies and music (especially
Video Dises and video tapes bearing the DO [bormy sune
mark) playback. DOLBY PRO LOGIC SURROUND contin-
uously detects the size and direction of the dominant
signal and cancels undesirable crosstalk, thereby provid-
ing signal emphasis.
it makes you clearly perceive the directions where music
comes from. Real flow of sound also can be re-created
naturally using this feature. You can feel as if being in the
outstanding and expansive sound field, When tsing
DOLBY PRO LOGIC SURROUND, a delay time setting of
20 ms is commonly used. Use a different setting if you
prefer. Even if they do not bear the D][oisy i] mark,
some video recordings may be Dolby Surround encod-
ed. Choose the SIMULATED SURROUND mode if the
source sound signal is mono. Little or no sound will be
heard from the surround speakers if the STADIUM or
DOLBY PRO LOGIC SURROUND mode is selected.
With DOLBY PRO LOGIC SURROUND, monaural source
sound will be heard only from the center channel at
settings other than the PHANTOM position.
Note:
Doiby Surround will not operate correctly if the signal passes
through a graphic equalizer. When using Dolby Surround,
turn off the TAPE 2 MONITOR or set the graphic equalizer for
flat response or to its “through” (or off) setting, if you have
one in use.

_DOLBY PRO LOGIC SURROUND, CENTER MODE
(For DOLBY PRO LOGIC SURROUND)
You can choose from the following settings:
Center Mode Choices:
When using a center speaker:
@ NORMAL — Low range frequencies, which have little
effect on directionality and positioning, are routed to
the left and right front speakers. So you can use a
relatively smail size speaker as the center speaker.
e@ WIDE — If you use a large size center speaker, choose
this setting. The full frequency range of the Doiby
Surround center channel, from low to high, is routed
to the center speaker,
e PHANTOM — The signal which would have been
sent to the center speaker is divided equally between
the left and right front speakers.
With DOLBY PRO LOGIC SURROUND, monaural source
sound will be heard only from the center channel at
settings other than the PHANTOM position.

NOTE:
© To avoid interference with the picture on a nearby TV set, use
magnetically shieided speaker systems. This is particularly
important for the center speaker since it is usually located
closest to the TV.
e. Position the left and right channel speakers at equal distanc-
es from the TV set and approximately 1.8 m (6 feet) trom each
. other.

VENTILATION
@ When installing this unit, make sure to leave space around
the unit for ventilation to improve heat radiation. if not
enough space is provided between the unit and walls or other
equipment, heat will buifd up inside, interfering with
performance or causing malfunctions.
tf this unit is used in a stack of components, please be sure
to install it at the very top of the stack.
@ Do not place on a thick carpet, bed, sofa or fabric having a
thick pile. Do not cover with fabric or other covering.
Anything that blocks ventilation will cause internal
temperature to rise, which may lead to breakdown or fire
hazard.

Connect the center speaker to these terminals.
NOTE:
Do not allow any of the cord’s conductors to protrude from the
terminals or touch any other conductors. Malfunctioning or
breakdowns may occur when conductors come into contact
with each other. Use center speakers with impedance of 8&2 to
7682.
1f REAR SPEAKERS terminalis
Connect the rear speakers to these terminals.
NOTE:
e Do not allow.any of the cord’s conductors to protrude from
the terminals or touch any other conductors. Malfunctioning
or breakdowns may occur when conductors come into con-
tact with each other. Use rear speakers with impedance of
SQ to 76a.
e Be sure to connect two speakers {L, R). There will be no sound
if only one speaker is connected.
‘4 Power cord
POWER-CORD CAUTION
Handle the power cord by the plug. Do not pull out the
plug by tugging the cord and never touch the power cord
when your hands are wet.as this could cause a short
circuit or electric shock. Do not place the unit, a piece of
furniture, etc., on the power cord, or pinch the cord.
Never make a knot in the cord or tie it with other cords.
The power cords should be routed such that they are not
likely to be stepped on. A damaged power cord can cause
a fire or give you an electrical shock. Check the power
cord once in a while. When you find it damaged, ask your
nearest PIONEER authorized service center or your deal-
er for a replacement,

e® Place the antenna on a level surface and rotate it to
locate the orientation that yields the best reception.
« Use the attachment hole in the ieg to screw it to the
wall or other location, then insert the claw on the

Precaution regarding installation position of
cassette deck.
Hf the cassette tape deck is installed in the ‘4’ positions as
shown
in
the
drawing
below,
it
may
be
adversely
affect-
ed during playback. If possible, it is better to install it in
the 8 position.
| HINTS FOR BETTER RECEPTION
EXTERNAL FM ANTENNA |
The main advantage of FM over AM is the quality of the
broadcast signal. In order to benefit fully from the high
signal quality of FM broadcasts, it is recommended that
a special-purpose FM antenna be installed. In weak sig-
nal areas, a multi-element (3-element, 5-element, 7-ele-
ment) antenna should be used,
GROUNDING |
Grounding is recommended if reception of FM programs
is impaired by noise. To ground, connect a thick polyvi-
nyl-insulated wire to the GND terminal and attach the
other end to a metal water pipe or grounding bar or wind
it around a copper plate and bury it.
NOTE:
Never connect 4 wire to a gas pipe for grounding since sparks
may ignite the gas.
[EXTERNAL AM ANTENNA
If it is not possible to obtain adequate AM reception even
by changing the orientation of the AM loop antenna, a
separate
indoor
antenna
or
an
outdoor
antenna
should
be installed.
INDOOR AM ANTENNA
Use a vinyl-insulated wire 5 to 6 meters long (15 to 18
feet) and connect one end to the AM antenna terminal
and affix the other end to the wail or ceiling, as high as
possible.
NOTE:
Do
not
detach
the
AM
loop
antenna
when
using
an
indoor
or
an
outdoor
AM
antenna.
