ee
a
Surround System (TX-906 only)
Many
motion
pictures
produced
in
the
last
decade
have
been
released
in
“Dolby
Stereo”
sound,
with
music,
dialogue,
and
panned
effects
coming
from
the
3-channel
front
soundstage,
and
surround
effects
and
ambience
emmanating
from
the
sides
and
rear
of
the
theater.
These
four
channels
are
encoded,
or
matrixed,
into
a
two-channel
DOLBY
STEREO
release,
and
decoded
in
the
theater
by
a
professional
DOLBY
STEREO
MP
(Motion
Picture)
decoder.
These
surround
sound
effects
are
“hidden’
in
the
two-channel
stereo
movie
release,
and
decoded
in the theater by special Delby equipment.
These
same
two-channel
motion
picture
masters
are
used
for
production
of
stereo
VHS,
VHS-HIi-Fi,
Beta
Hi-Fi,
and
stereo
Laser
Vision
discs
that
you
can
buy
or
rent
at
your
video
store.
The
TX-906
incorporates
the
Dolby
Pro
Logic
Surround
Circuit,
which
is
designed
to
emulate
the
audience
experience
found
in
DOLBY
STEREO
theaters.
Like
DOLBY
SURROUND,
DOLBY
PROLOGIC
SURROUND
is
capable
of
creating
a
multi-dimensional
soundstage,
but
with
the
increased
channel
separation
it
gives
a
far
greater
sense
of
“movement”
and
sound
localization.
Just
like
in
the
theater,
the
addition
of
the
active
center
channel
ensures
that
ail
audience
members
hear
dialogue
coming
from
its
on-screen
sources regardless of seating position.
Since
the
TX-906
is
equipped
with
a
front
amplifier
and
a
rear
(surround)
power
amplifier,
Dolby
Pro
Logic
Surround
and
Hall,
effects
can
all
be
produced.
You
can
enjoy
the
feeling
of
a
movie
theater
or
concert
hal!
in
your
own
room.
To
reproduce
these
effects,
rear
(surround)
speakers
and
center
speakers
are
necessary.
The
placement
of
these
speakers
is
important.
You
can
experiment
with
various
positions
and
locations to find the best placement for optimum sound quality in your roam.
*
The
TX-906
comes
without
a
center
power
amplifier.
Use
a
power
amplifier
with
a
power
rating
equal
to
or
better
than
the
front
amplifier
of
the
TX-906.
Without
a
center
power
amplifier,
you
can
add
the
Dolby
Pro
Logic
Surround
Sound
effect
to
the
playback,
by
setting
the center mode to PHANTOM.

® Dolby Pro Logic Surround (TX-906 only)
When
using
video
cassette
tapes
or
video
discs
that
have
the
DOLBY
STEREO
or
DOLBY
SURROUND
trade
mark,
you
can
achieve
the
same kind of sound in your room that you experience in a movie theater.
The
main
Dolby
Pro
Logic
Surround
functions
are
sent
through
the
center
channel.
Because
of
this,
three
modes
must
be
available
from
the speaker and the center amplifier used by the center channel.
1.
Normal:
When
a
small
speaker
is
used
on
the
center
channel,
signais
of
100
Hz
or
more
are
output
from
the
center
speaker,
and
signals
of
100
Hz
or
less
are
split
between
the
front
L
and
R
channels.
2.
Wide
band:
When
the
front
L
and
R
channels
are
using
similar
speakers
on
the
center
channel,
it
operates
throughout
the
full
frequency
range.
3.
Phantom:
When
no
center
speaker
is
used,
the
center
channel
signal
is
split
between
the
front
L
and
R
speakers,
producing
the
same
resuits
as
found
with
a
center
speaker.
® Hall
In
most
cases,
the
same
kind
of
sound
that
you
experience
in
a
theater
or
concert
hall,
and
the
natural
expansion
of
sound,
can
be
achieved
with a music source.
Hall mode would be best suited to jazz and classical.

FM Antenna Connections
Use the T-shaped antenna if you live in an area where signal strength
of FM broadcasts is high. Connect the antenna to the FM 300 ohms
terminals and place the antenna on a wall or other surface in the
position in which reception is best. If signal strength is low in your
area, use a muiti-element FM outdoor antenna and connect to this
unit using a 75 ohm coaxial cable because this type of cable is
more resistant to interference than 300 ohm cable. Consult your
ONKYO
authorized
service
center
about
the
right
type
of
antenna
for your area.
NOTE:
Do not use the same antenna for both FM and TV (or VCR)
reception
since
the
FM
and
TV
(or
VCR)
signals
can
interfere
with each other. ff you must use a common FM/TV (or VCR)
antenna, use a directional linkage type splitter.

Turntable Connections (PHONO)
Connect the output leads of the turntable to the PHONO jacks.
Be sure to connect the ground (earth) lead wire from the turntable
to the ground terminal (GND). Lack of proper ground connection
will cause hum. Turntables not provided with GND wires do not
need to be connected.
1.
Place
the
turntable
on
a
firm
shelf
or
deck
free
from
vibrations
(especially those generated by the speaker system). If the
turntable is permitted to pick up such unwanted vibrations, not
only with the performance of the unit drop, but distortion in the
bass frequencies and howling in the speakers may also occur.
Check the turntable instruction manual for any other precautions.
3. The loud noises that occur when connecting and disconnecting
the turntable leads, replacing the cartridge or lowering the
tonearm could damage the speakers. Always turn the power
switch off before making connections.
4. If an ONKYO turntable with remote control jack is used with
this unit, the remote control transmitter can also be used to start
and stop turntable operation. In this case, the turntable and
TX-906/904 must be connected with a remote control cable.
Insert the plug into the PHONO jack of the REMOTE CONTROL
on the rear panel of the TX-906/904. (Please refer to “Con-
nections for Remote Control”.)
