The SX-9000 employs the latest circuitry, including FET and lC's.
The result is a professional receiver of exceptional sensitivity and
stabi Iity.

In addition to the normal bass and treble controls, there is a
4-position tone color selector knob. This providesquick switching

To remove the fuse, turn the fuse cap located on the line
voltage selector switch in the direction indicated by the
arrow. Then remove the fuse plug from the unit. Put the
fuse plug back so that the proper line voltage marking can
be seen through the cut on the edge of the plug. Whenever
the position of the selector switch is changed, check the
rating of the fuse. A 1.5-ampere fuse is to be used foreither
22OY or 240V operation and a S-amperefuse for 110V, F U S EC A P

STEREOSYSTEM
The SX-9000 is general-purpose stereo amplifier. Connect it
to the speaker systems (two to six), turntable, tape
recorder, etc., which are separatelyavailable.
INSTALLATION
When installing your stereo system, check the following
points.
o The place should be well-ventilated, and free from
dampnessand dust.
o The units should not be exposed to direct sunlight.
o The units should not be placed near radiators or other A SPEAKER SYSTEM B SPEAKER SYSTEM C SPEAKER SYSTEM
heating units.
o The place should be substantial and roomy enough for the Fig. 2
installation, when installing the unit on a shelf.
A WORD ABOUT ROOM ACOUSTICS
The quality of reproduced sound varies according to the
size and shape of the room, the materials of walls, floor
and ceiling and the amount and arrangement of fumiture.
Too harsh or "bright" a sound usually results from too
many hard reflecting surfaces, and/or too low a ceiling.
This condition is improved by having ample carpet area or
covering the wall (especially that facing the speakers)with
a thick curtain.
On the other hand, too many absorbing surfaces will tend
to "soak up" the sound, resulting in a certain "deadness".
Furniture may be rearranged to provide irregular reflection
of the sound. In any event, the true stereo effect is lost if
the two speaker systems are placed too far apart. This may
be corrected by angling them slightly toward each other or
reducing the distance between them.
SPEAKHRSYSTEMCONNECTIONS
o First remove the speaker connector plugs from the
accessoriesbag and then connect the speaker leads as
shown in Fig. 3. Be sure to match the speaker and plug
polarities.
o After the plugs are connected, insert the one for the right
channel in the left side of the SPEAKER OUTPUTS (A)
panel on the rear of the unit. Connect the left channel to
the right side of this panel as shown in Fig.3.(Refer also
to the connection diagram on Page4.)

ANTENNA
AND GROUND
CONNECTIONS
When using the SX-9000 at a place of low field strength or
distant from the station, select the most suitable FM and
AM antennas as follows, and the efficiency of any antenna
depends on its height more than its length.
FM ANTENNA
o Reception is easier if the building is primarily of wood
and is near the FM station, in this case,use the accessory
T-type indoor antenna. Unfold the horizontal section of
the antenna to its full length, and determine the best
Fig.
direction for the antenna while actually receiving an FM
broadcast program. Attach the horizontal section to a
wall or other place in the determined direction. (SeeFig.4.) -' FM OUTDOOR ANTENNA
o When using the SX-9000 at a relatively long distance
from the station, or within a building or home with
relatively thick walls, or vicinity of tall buildings, erect an
AM OUTDOOR
FM outdoor antenna, and connect it to the FM antenna ANTENNA
terminals as shown in Fig. 5.
AM ANTENNA
o If your house is located in area relatively close to the AM
station, the ferrite loopstick antenna provided on the
back of the SX-9000 will be sufficient for reception of
AM broadcast program. The antenna is directional it
should be moved about while listening to a station and
set at the position which provides the best reception. Fig. 5
( See Fig. 6. )
. If the loopstick antenna does not provide sufficient
sensitivity for reception and static is noticeable, put the
furnished antenna wire on the wall and connect one end
of the wire to the AM antennaterminal. (SeJfig. +.;
o If you want reception from a distant AM station, you
may have to set up an AM outdoor antenna. In such a
case, connect one end of the AM outdoor antenna to the
AM antenna terminal. (See Fig. b.)

USINGMICROPHONES
The SX-9000 permits the use of two microphones at once,
for such purposes as recording a concert in stereo; even
performances or dramas in large theaters can be efficiently
recorded.
1. Turn the VOLUME - SOURCE knob all the way down if
microphone recording only is desired.If mixed recording,
combined with music from a record, etc., is desired, set
the SOURCE knob to the best level.
2. Tii,e MIC LEVEL A knob controls the input from a
microphone plugged into MIC jack A; knob B controls
jack B. Tum either of these knobs to the right to increase
input signal strength. Adjust the level while watching for
"howling" (acoustical feedback of the speaker signal
through the microphone). If this occurs, reduce the
volume or separate the microphone(s) and speakers.If
only one microphone is used, plug it into either jack. If
setting the MIC LEVEL for another jach not being used to
OFF, the sound will be reproduced from both speakers.
NOTE: When adjustingthe MIC LEVEL control, be careful not to cause
howling.
