IMPORTANT PRECAUTIONS
To keep the unit in top condition at all times, observe the following precautions.
Installation locations
- * Do not expose the unit to rain or sun. Such exposure is dangerous, since it may eventually be the cause of circuit burnout or fire, or give electric shock to whomever tuckes the unit.
- Avoid extremely dusty locations, or close proximity to heating appliances or placing it in direct sunlight.
- * Never remove the side and bottom plates. Such removal is both physically and electrically dangerous to you and the unit.
- * Keep the unit away from TV sets to avoid buzz noise.
Installtion
You should mount the unit on a solid shelf or stand. Of the five feet on the unit's bottom board, the two, located near the rear panel, can be moved 4.5 cm (2 inches) toward the front panel, a feature useful when mounting the unit on a narrow shelf. The screws, located in the oval recesses in the bottom board, are provided for this purpose. Never remove the feet for mounting, since the ventilation outlets will be blocked, giving rise to the possible cause of breakdown.
Ventilation
Never obstruct the ventilation outlets on the unit's top, bottom boards, and on the rear panel. Take extra care about ventilation when placing equipment, etc. atop the unit or mounting the unit in a sealed box; using the unit in such a condition may lead to an eventual breakdown. There's a protection circuit inside the unit that cuts the output temporarily in case the internal temperature rises above a certain level.
CONNECTION
Note
- Prior to any connection, be sure that the POWER switch is at the OFF position.
- When using the "SWITCHED" and "UNSWITCHED" AC outlets of the unit, never connect components whose total power consumption exceeds the capacity of each outlet.
- * In connecting tape decks, do not use the TAPE-2 pin-jack terminals and the DIN socket simultaneously.
- * Noise and breakdown may be caused when defective cords are used, when connection is imperfectly made or when loose ends of connection cord lead wires are in contact with the unit or other components. Therefore, when connections are completed, check that they are correctly made and that the plugs and connection cords are in proper working condition.
Speaker impedance
When connecting one pair of speaker systems, each of them may have any impedance from 4 to 16 ohms. When connecting two pairs, each must be from 8 to 16 ohms. Breakdown may occur if you use speaker systems with lower-than-specified impedances. Follow this instruction strictly when driving two pairs of systems simultaneously. Impedance of a speaker system is usually specified on the unit itself or in its instruction leaflet.
UNSWITCHED SWITCHED TOTAL 250W MAX 100W MAX
NOTE: No AC outlet is provided on units sold in some areas owing to local laws and regulations.
REMARQUE: Aucune sortie AC (Courant Alternatif) n'équipe les modèles vendus dans certaines régions en raison des réglements locaux.
ANMERKUNG: Aufgrund örtlicher Vorschriften und Gesetze sind in manche Gebiete gelieferte Geräte nicht mit Wechselstrombuchsen ausgestattet.
AC outlets
Of the three AC outlets provided on the rear panal, the one, marked "SWITCHED," is controlled by the front-panel POWER switch. It is convenient to use it to power a program source component such as your turntable etc.
The other two AC outlets, marked "UNSWITCHED," are not controlled by the unit's POWER switch; so long as the unit is connected to a wall outlet the connected components are also powered.
a wall outlet, the connected components are also powered. The "SWITCHED" and "UNSWITCHED" outlets have a capacity of 100 watts and 250 watts respectively. Do not connect any component whose power consumption exceeds the capacity of each outlet, as it is extremely dangerous. The power consumption rating is usually listed in the specification chart of the component, or sometimes on the exuinment itself be sure to check the rating.
In case you have connected a component to one of the unit's AC outlets and then another component to the first component's AC outlet, be sure to add the second component's rated power consumption to the consumption of the components connected to the unit itself.
Short pin-plugs
Pin-Plugs are inserted in the PHONO-2 terminals of the unit to decrease noise prior to delivery from our factory. Since unused terminals without short pin-lugs can cause an increase in noise, be sure to keep them inserted when you use only one turntable. Never re-insert them into the TAPE REC, PRE OUT, or MAIN IN terminals, for then you will be unable to hear any sound at all.
Cable guides on side panels
Terminals for the inputs and outputs are provided on the side panels of the unit: inputs on the right panel and outputs on the left. Since they are located near the front panel, you can make connections easily after simply pulling the unit out toward you. Connection cables can be bundled neatly when they are run behind the cable guides.
Speaker connection
Speaker connection To SPEAKERS SYSTEM-A or B terminals, connect speaker cords taking care not to confuse the right channel with the left and plus polarity with minus.
Connecting a tuner
A tuner should be connected to the TUNER terminals on the right side panel. If there's an output level control on your tuner, adjust its so that the tuner output level matches the phono output level; you will then be saved the trouble of adjusting the volume each time you change the program sources.
Since an antenna is indispesable for good radio reception, especially of FM broadcasts, you are advised to install a quality antenna and, moreover, use quality cords for connection.
Turntable connection
Connect your turntable to the PHONO-1 terminals. When using two turntables or two tonearms, use the PHONO-2 terminals too. When your turntable is equipped with a grounding cable, connect it to the unit's GND terminal. But disconnect it when you notice increased hum.
Tape deck connection
You can connect up to two tape decks to the unit. Connect the unit's TAPE REC terminals to the line input terminals of your tape deck, and the unit's TAPE PLAY terminals to the output terminals of the deck. The DIN socket connects with the identical socket on your tape deck via a DIN cable.
- The TAPE-2 circuit is duplicated, one by pin jacks and the other by the DIN socket. Do not use the jacks and the socket at the same time.
- For information about the AUX PHONO-1 PICKUP LOAD, PHONO-1 SENSITIVITY and PRE-MAIN Separate Switches, refer to the section SOME USEFUL HINTS.

Listening to radio broadcasts
- 1. Confirm that the VOLUME control is not turned too far to the right; it should be at a position where you can obtain the normal listening local
- 2. Set the TUNER selector to the ON position. Confirm that the TAPE PLAY switch is at the SOURCE position and the TAPE COPY switch at the OEE position
- 3. Operate the tuner to receive the desired station.
- Operate the tuner to receive the desired station. Adjust the unit's other controls and switches to suit the type of music you are hearing.
Noise during radio reception
- * Week FM signals are often disturbed by ignition noise from nearby automobiles and other noise. Therefore, for better FM reception, installation of an outdoor FM antenna is suggested. For antenna connection, be sure to use a coaxial cable, not a feeder-type cable.
- When you hear noise during AM reception, there are innumerable conceivable causes, which makes it almost impossible to eliminate all AM noises. Use the unit's filters when both grounding the unit and mounting a noise-eliminating device fail to reduce such noise.
Playback of tapes
- Confirm that the VOLUME control is not turned too far to the right; it should be at a position where you can obtain the normal listening level.
- Turn the TAPE PLAY switch to the TAPE-1 or TAPE-2 position, depending on which TAPE PLAY terminals the corresponding deck is connected to.
- 3. Operate the tape deck to start playback.
- Adjust the unit's other controls and switches to suit the type of music you are going to hear.
Poor-quality tape playback
High-frequency hiss is noise inherent in tape. Eliminate it with the unit's HIGH FILTER switch. The noise increases when the heads of your tape deck are magnetized. For elimination of such noise, refer to the instruction book of that tape deck.
Recording disc records and radio broadcasts
You can record disc records or radio broadcasts on one or two connected tape decks at the same time. Recording level adjustments that the made with the tape decks
- Prepare a program source (records or radio broadcasts) you want to record
- Set the TAPE COPY switch to the SOURCE position.
- 3. Operate the tape deck(s) on which you are going to make a recording
- 4. If you want to monitor the sound as you record it, simply follow exactly the same instructions as for tape playback (desribed above). Also operate the tape deck (s) for monitoring. Monitoring is possible with a tape deck with independent heads for record and play. If your tape deck has a combined head for record and play, however, you cannot monitor; set the TAPE PLAY switch to the SOURCE position and listen to the sound before it is recorded.
- Recordings dubbed from disc records or radio broadcasts should not be used in public without prior consent of the original copyright owners.
Tape-to-tape copying
- Adjust the TAPE COPY switch to one of its two positions: 1▶2 or 2▶1, depending on which tape deck you wish to use for playback and which tape deck for recording.
- 2. Operate the tape decks, one for playback and the other for recording
- If you wish to monitor the sound as you record it, follow the same instructions as for tape playback.
To hear the sound before it is dubbed, turn the TAPE PLAY switch to the circuit (TAPE-1 or TAPE-2) to which the deck in playback mode is connected. To monitor the sound after it is dubbed, turn the switch to the circuit to which the deck in record mode is connected.
When you turn the TAPE PLAY switch to the SOURCE position during tape-to-tape copying or dubbing, you can enjoy other program sources (records or radio broadcasts) without interrupting the dubbing process.

When you hear no sound
Some of the symptoms which seem to indicate a breakdown of the unit are caused by misoperation of the unit or other connected components. Confirm the connections and your operating procedure once more. Be sure to turn the power off or reduce the volume beforehand.
Check list of operation
- 1. Is the POWER switch turned on?
- Is the POWER switch turned on? Is the TAPE PLAY switch set to SOURCE when you do not wish to reproduce a tape?
- Are the INPUT SELECTOR switch and TUNER selector turned to the correct positions?
- 4. Is the SPEAKERS switch turned to the correct position?
- 5. Is the PRE-MAIN separate switch set to CONNECTED?
Check list of connections
- 1. Is the power cord inserted in a wall-AC outlet?
- Stille power conditions that in a warrace output: Are the connection cords for your turntable and tape deck loose or touching some other object?
- 3. Are the speaker connection cords loose from the unit or the speakers?

SOME USEFUL HINTS
Changing response according to the cartridge in use
PHONO-1 SENSITIVITY Switch
Set this switch to the position which roughly corresponds to the output voltage (rated) of the cartridge in use or the output voltage of a step-up transformer if one is used. (The rated output voltage of a cartridge is usually listed in its specification chart.) The switch changes the input sensitivity of the PHONO-1 circuit only.
PHONO-1 PICKUP LOAD Switch
With the PHONO-1 circuit, you can change the input resistance (or load resistance of the cartridge in use) from 50 kilo-ohms to 30 kilo-ohms to 100 kilo-ohms. The result you will obtain is a subtle change in level in the high-frequency response. Select the position to best suit the response to your taste.
How to use AUX inputs
"AUX" means auxiliary, and the AUX inputs have the same electrical function as the TAPE PLAY inputs. They therefore connect a tape deck, a CD-4* demodulator, an adaptor for special cartridges, and other equipment that provides about same output level as the afore-mentioned components.
*CD-4 is a trademark of JVC, Inc.
Separation of preamplifier and power amplifier sections
With your unit, you can separate the preamplifier (control) section from the main (power) amplifier section for independent uses; you can connect a separate preamplifier or power amplifier to the unit, or construct a multi-amplifier (electronic crossover) system. To separate these two sections, set the PRE-MAIN separate switch on the left side panel to SEPARATED. Be sure to set the POWER switch to OFF beforehand. Connect the PRE OUT terminals to the input terminals of the separate power amplifier or, in constructing an electronic crossover system, to the input terminals of a channel divider. The MAIN IN terminals should be connected with the output terminals of a separate preamplifier or of a channel divider.
In an electronic crossover (multi-amplifier) system, the entire audio frequency spectrum is divided into several ranges, and each range is amplified by a separate amplifier and reproduced by a separate speaker unit. This system allows you to improve tonal quality better suited to your taste. Ask your Sansui dealer for further information.
4-Channel system
In a matrix 4-channel system, the 4-channel adaptor should be connected to the TAPE-2 REC/PLAY terminals. You can use the unit's tone control circuits for tonal adjustments of the front channels.
Grounding
Grounding the unit may reduce hum during record playback and noise during AM reception.
Grounding the unit to earth
Connect one end of a vinyl or enameled insulated cord to the GND terminal of the unit and the other end to a copper plate or carbon bar. Then bury the plate or bar deep under the ground. The other end of the cord may be connected to a metallic water pipe. NEVER connect it to gas pipe, since it is dangerous. Earth grounding of the unit is unnecessary when one of the connected components is already grounded to earth.
