The STR-GX909ES/STR-GX808ES is an FM Stereo/FM-AM receiver and audio/video
control center.
You can enjoy various audio/video program sources with this unit.
Amplifier
* Optical Legato Linear A System allows the receiver to
operate automatically as a class A amplifier when the
level is low and as a class B amplifier when the level is
high without disturbing the sound signal. This minimizes
total harmonic distortion at every sound stage.
¢ This receiver has a spontaneous twin drive power circuit.
Condensers having large capacity are used
independently for the voltage amplification drive stage of
class A and power output stage of class B. Thus, a stable
output and high quality sound are obtained, resulting in
exclusion of power interferences.
The class A stage realizes a stable operation free from
interference of the power stage even when an
instantaneous or strong output is received.
TVivideo programs
e You can enjoy TV or CATV programs with FM simulcast.
© Sounds from various audio program sources can be
added on video tapes during editing.
Tuner
¢ Precise tuning is ensured by a quartz locked digital
synthesizer.
* Station Index system allows you to tune into a station
quickly.
Powerful surround sound
By connecting the power amplifier to the SURROUND OUT
jacks of this unit, you can obtain powerful surround sound.
Dynamic sound from the front speakers
By connecting the power amplifier and the pre-amplifier to
the PRE OUT and MAIN IN jacks of this unit respectively,
you can obtain a dynamic sound from the front speaker.
(See page 10)
LOW FILTER switch
This unit has the LOW FILTER switch which cut the low
frequency signal from the front speakers. (See page 10)
Digital surround processor
* The STR-GX909ES/STR-GX808ES electronically
reproduces the reflected sound (early reflection) and
reverberation sound (reverberation) by using its digital
signal processor, and allows you to obtain the acoustics
of various situations.
DOLBY* PRO LOGIC: The STR-GX909ES/STR-GX808ES
incorporates the Dolby Pro Logic Surround Decoder
which has the same functions for playback as movie
theaters and gives a theater-like experience in your
a room, naturally reproducing the audio sound
ield.
.
Manufactured under license from Dolby Laboratories Licensing
Corporation. Additionally licensed under one or more of the following
patents: U.S. number 3,959,590: Canadian numbers 1,004,603 and
1,037,877. “Dolby”, “Pro Logic”, and the double-D symbol are trademarks
of Dolby Laboratories Licensing Corporation.
Digital parametric equalizer
You can enjoy audio program sources with appropriate
equalization curve by controlling the level of the desired 3
frequency bands.
Sound field
¢ 10 recommended sound field programs (combination of
surround and parametric equalizer settings) are preset in
the factory for easy use. You can also store up to 10
settings you created in the memory.
© Combined use of the sound field programs and the preset
stations allow you to enjoy broadcast listening
immediately with the memorized sound field settings.
ON SCREEN function (STR-GXS09ES only)
This function allows you to monitor the operation being
performed on the monitor TV.
TITLE function (STR-GX909ES only)
With this function, you can edit a title and superimpose on
your picture.
Remote commander supplied
The STR-GX909ES/STR-GX808ES is supplied with the
RM-P331 which can “tearn” the various functions of other
remote commanders of the infrared type.
The FUNCTION/SOUND FIELD/PRESET TUNING buttons
There are two kinds of modes for the FUNCTION/SOUND
FIELD/PRESET TUNING buttons. One is the “Auto mode”
and the other is the "Manual mode". With these modes, you
can conveniently operate this receiver.
This manual describes the operations in the auto mode.
This instruction manual covers the STR-GX909ES and
STR-GX808ES.
The followings are only for the STR-GX909ES.

STR-GX909ES.

Precautions
On safety
© Operate the unit only on 120 V AC, 60 Hz.
¢ Should any solid object or liquid fall into the cabinet,
unplug the unit and have it checked by qualified
personnel before operating it any further.
© Unplug the unit from the wall outlet if it is not to be used
for an extended period of time. To disconnect the cord,
pull it out by grasping the plug. Never pull the cord itself.
© One blade of the plug is wider than the other for the
purpose of safety and will fit into the power outlet only
one way. If you are unable to insert the plug fully into the
outlet, contact your dealer.
© To detach the side panel, first disconnect the power cord
from the wall outlet. Remove the screws on both sides to
detach the panels and fasten the supplied screws into the
holes on the unit. (STR-GX909ES only)
To prevent internal heat buildup in the unit,
place the unit in a location with adequate air circulation.
Do not install the unit:
© near heat sources such as radiators or air ducts.
¢ in a place subject to direct sunlight, excessive dust,
mechanical vibration or shock.
Do not place anything on top of the cabinet.
The top ventilation holes must be unobstructed for the
proper operation of the unit and to prolong the life of its
components.
Do not throw away the carton and packing material!
It will be an ideal container when transporting the system for
repair work, etc.
On operation
Before making program source connections, be sure to turn
the power switch off and unplug the unit.
On cleaning the cabinet
Clean the cabinet, panel and controls with a soft cloth lightly
moistened with mild detergent solution. Do not use any type
of abrasive pad, scouring powder, or solvent such as
alcohol or benzine.
For the customers in the U.S.A.
For detailed safety precautions, see the “IMPORTANT
SAFEGUARDS’ leaflet.
If you have any question or problem concerning your unit,
please consult your nearest Sony dealer.

Commander
Before operating remote commander, install the batteries as
shown.
2 Two size AA (R6) batteries
with correct polarity.
1 Open the cover.
To avoid damage caused by battery leakage and
corrosion
When the commander will not be used for a long time,
remove the batteries.
Battery life
Normal operation can be expected about a half year using
Sony SUM-3 (NS), and a year using Sony AM-3 (NW)
alkaline batteries.
When the batteries are run down, the remote commander
will not operate the unit. In this case, replace batteries with
new ones.
Selecting the AM Tuning Interval
The AM tuning interval is preset to 10 kHz. To use the
receiver where the frequency allocation system is based on
a 9 kHz interval, make the following adjustments.
1 Turn on the power and tune in any AM siation.
2 Turn off the power.
3 Press the POWER button while pressing the INDEX
SELECT/TUNING + button.
To reset the AM tuning interval, repeat the above steps.
Caution
When the interval is changed, all preset stations which you
have memorized will be erased. After changing the interval,
be sure to preset the stations again.

Hooking Up the System
At first, this section describes about the antenna connection and then the connection
with the other equipment. After that, it shows about the speaker connection and about
the AC outlet.
The STR-GXS809ES/STR-GX808ES has the SURROUND OUT jacks on the rear panel.
© Do not connect the power cord to an AC outlet nor press
the POWER switch before accomplishing all other
connections.
© The cable connectors should be fully inserted into the
jacks. Loose connection may cause hum and noise.
* Jacks and plugs of the connecting cord are color-coded
as follows:
Red jacks and plugs: For the right channel of audio
signals
White jacks and plugs: For the left channel of audio
signals
Yellow jacks and plugs: For video signals
Connecting an FM Antenna
Though the wire antenna is supplied with this unit, the higher
quality sound will be obtained with the 75-ohm coaxial
cable.
Supplied wire antenna
For higher quality sound
75-ohm coaxial cable
(optional)
Ofoyalatzrostiale m-taWANi imal (ralar:|
The AM broadcast is enough received with the supplied AM
loop antenna. However, the connection of insulated wire is
also available for areas with difficult AM reception.
Adjust the

“
Ca m
Supplied AM loop antenna
For areas with difficult AM reception
In areas with troubled reception, connect a 6 to 15-meter
(20 to 50-feet) insulated wire to the AM antenna terminal.
Extend this out of doors if possible, keeping the greater
portion horizontal.
(There is no need to disconnect the supplied antenna.)
To prevent hum
Connect the ground wire to ANTENNA ground terminal (74).
When an outdoor antenna is installed, be sure to connect
the ground wire for lightning protection.
