The circuitry is qrlite advanced, on a par with professional designs. CLEAN-LINED, CONTEMPORARY APPEARANCE The SX-9000 looks good, too. The front incorporates a folding panel that adds to its distinctive design. When in operation, the smoked glass dial window lights up with subdued illumination. and the source also lights up 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 stab i I ity. PRE-SET TONE COLORS In addition to the normal bass and treble controls, there is a 4-position tone 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 MON ITOR I NG Two buttons on the front panel allow easy, one-touch monitoring of tapes "A" or "8" when you use the SX 9000 to copy directly from one tape to another. FOOLPROOF MICROPHONE USE When either microphone knob is set to OFF, the unit operates in parallel to provide monophonic signals for both speakers without having to set the mode switch. REVERBERATION EFFECT Also included is a reverberation effect knob. The degree of "echo" is easily read in the "Reverberation" window in the dial face" SPECIAL "OVERLOAD PROTECTION'' You can play up to three different pairs of speaker systems through 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 action and the speakers are automatically shut off. EARPHONE VERSATILITY Because the SX-9000 has two "earphones" output jacks, two people may I isten simu ltaneously with earphones without having to go through an accessory junction box.

I TJTONEER LINE VOLTAGE SELECTION AND FUSE SWITCHING LINE VOLTAGE SETTING AND 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 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-ampere fuse for 110V, 120V or 130V operation. If the rating of the fuse is correct, replace cap. FUSE REPLACEMENT If the fuse blows, remove the fuse cap and replace the fuse with a new one. STEREO SYSTEM The SX-9000 is general-purpose stereo amplifier. Connect it 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 dampness and dust. o The units should not be exposed to direct sunlight. o The units should not be placed near radiators or other heating units. o The place should be substantial and roomy enough for the 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.
