FEATURES

A MULTI-PURPOSE,

EASY-TO.USE

DESIGN

The SX-9000 was designedto give you a high degreeof versatility

in operation.

You can,for example,

usetwo microphones,two tape

decks,

two headsetswith the SX 9000. All controls are rationallv

placed

for easy use.

The circuitry is qrlite advanced,on a par with

professional

designs.

CLEAN-LINED,CONTEMPORARYAPPEARANCE

The SX-9000 looks

good,too. The front incorporates

a folding

panel

that adds to its distinctivedesign.When in operation,the smoked

glass

dial window lightsup with subduedillumination.andthe source

alsolightsup for quick identification.

HIGH

PERFORMANCE

TUNER

The SX-9000 employs the latest

circuitry, including FET and lC's.

The resu

lt is a professional receiver of exceptional sensitivity and

stabiIity.

PRE-SET

TONECOLORS

In addition to the normal bass and treble controls, there is a

4-positiontone color selector

knob. This provides

quick switching

from "flat" to "soft", "bass" or "vivid". These cttaracteristics

are

svmbolized

in an illuminated

window in the dial face.

TAPE-TO-TAPE

MONITOR

ING

Two buttons on the front panel allow easy,

one-touchmonitoring of

tapes "A" or "8" when you usethe SX 9000 to copy directly from

onetapeto another.

FOOLPROOFMICROPHONE

USE

When either microphone knob is set to OFF, the unit operatesin

parallel

to provide monophonic signals

for both speakers

without

having

to setthe modeswitch.

REVERBERATION

EFFECT

Also included is a reverberation

effect knob. The degreeof "echo" is

easily

read

in the "Reverberation"

window in the dial face"

SPECIAL

"OVERLOAD

PROTECTION''

You can play up to three different pairs of speakersystemsthrough

the SX-9000 in combinations

A, B, C, A+8, A+C, B+C. lf all three

are accidentally turned on, however,the "Overload Protection" goes

into actionand the speakers

areautomatically

shutoff.

EARPHONE

VERSATILITY

Becausethe SX-9000 hastwo "earphones" output jacks,two people

may Iisten simultaneously with earphones without having to go

through an accessory

junction box.

SWITCHING

LINE VOLTAGE

SETTINGAND FUSE

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 voltagemarking can

be seenthrough the cut on the edgeof the plug. Whenever

the position of the selector switch is changed,check the

ratingof the fuse.

A 1.5-ampere

fuse

is to beusedforeither

22OY or 240V operation and a S-ampere

fusefor 110V,

120V or 130V operation.

If the ratingof thefuseiscorrect,

replace

cap.

FUSEREPLACEMENT

If the fuse blows, removethe fuse capand replace

the fuse

with a new one.

STEREOSYSTEM

The SX-9000 is general-purpose

stereoamplifier. Connectit

to the speaker systems (two to six), turntable, tape

recorder,etc., which are separately

available.

INSTALLATION

When installing your stereo

points. system, check the following

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

heatingunits.

o The place should be substantial

and roomy enough

for the

installation, when installingthe unit on a shelf.

A WORD

ABOUTROOMACOUSTICS

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 arrangementof 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 areaor

coveringthe wall (especially

that facing the speakers)

with

a thick curtain.

On the other hand, too many absorbingsurfaces

will tend

to "soak up" the sound, resulting in a certain "deadness".

Furniture may be rearranged

to provide irregularreflection

of the sound. In any event, the true stereo effect is lost if

the two speakersystems

areplacedtoo far apart. This may

be corrected by angling them slightly toward eachother or

reducingthe distance

betweenthem.

CONNECTIONS

o First remove the speaker connector plugs from the

accessories

bag and then connect the speaker leads as

shown in Fig. 3. Be sure to match the speakerand plug

polarities.

o After the plugsare connected,insert the one for the right

channel in the left side of the SPEAKER OUTPUTS (A)

panel on the rear of the unit. Connectthe left channelto

the right sideof this panelasshownin Fig.3.(Refer also

to the connection diagramon Page4.)

. If you have one (or two) more speaker system(s),

connect them in the same way, using the B (and C)

terminals.

ANTENNA

AND

GROUND

CONNECTIONS

When using the SX-9000 at a placeof low field strengthor

distant from the station, select the most suitable FM and

AM antennasas follows, and the efficiency of any antenna

depends

on its height more than its length.

FM ANTENNA

o Reception is easierif the building is primarily of wood

and is nearthe FM station, in this case,

usethe accessory

T-type indoor antenna.Unfold the horizontal section of

the antenna to its full length, and determine the best

direction for the antenna while actually receivingan FM

broadcast program. Attach the horizontal section to a

wall or other placein the determineddirection.(See

Fig.4.)

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,erectan

FM outdoor antenna, and connect it to the FM antenna

terminalsasshown in Fig. 5.

AM ANTENNA

o If your houseis located in area

relatively closeto 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.

(

See Fig.

)

. 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 antennaterminal. (See

Fig. b.)

GROUNDING

The SX-g000 will provide stable performance

whether

grounded or not. In rare case,however, grounding may

help. If so, connect a wire from the GND terminal to a

water pipe or balcony, fastening

it FIRMLY. Neverusea

MICROPHONE

CONNECTION

Insert the plug on the microphone cord into either one of

the MIC jacks on the front panel of the unit.

Use both jacks when you wish to employ two microphones
