PRECAUTIONS: READ THIS BEFORE OPERATING YOUR UNIT
Grounding or polarization – Precautions should be taken so that the grounding or polarization of an appliance is not defeated.
Do not use force on switches, controls or connection wires. When moving the unit, first disconnect the power plug and the wires connected to other equipment. Never pull the wire itself.
Do not attempt to clean the unit with chemical solvents; this might damage the finish. Use a clean, dry cloth.
Be sure to read the “TROUBLESHOOTING” section regarding common operating errors before concluding that the unit is faulty.
To prevent lightning damage, disconnect the AC power plug and the antenna cable when there is an electrical storm.
Do not plug the AC power plug to the wall socket before you finish all connections.
Never allow metallic items (e.g. screwdrivers, tools, etc.) to come near the cassette deck’s record/playback head assembly in this unit. Doing so may not only scratch or damage the head’s mirror­smooth finish, it may change the magnetic characteristics of the heads, causing a deterioration in reproduction performance quality.
Although the cassette deck’s record/playback heads used in this unit are high quality heads with outstanding reproduction characteristics, they can become dirty through the use of old tapes or from dust accumulation over time. This can have a serious effect on reproduction quality. Clean the heads regularly with one of the commonly available head cleaners or with cleaning solutions.
The voltage to be used must be the same as that specified on this unit. Using this product with a higher voltage than that which is specified is dangerous and may result in a fire or other type of accident causing damage. YAMAHA will not be held responsible for any damage resulting from use of this unit with a voltage other than that which is specified.
The sound level at a given volume setting depends on a combination of speaker efficiency, location and many other factors. Care should be taken to avoid exposure to sudden high levels of sound, which may occur when turning on the unit with the volume control setting at high, and to continuous high levels of sound.
Sudden temperature changes and storage or operation in an extremely humid environment may cause condensation inside the cabinet. Condensation can cause the unit to malfunction. Follow the procedure below to eliminate condensation.

Placing the system
This system can be placed any way you like, however, be sure not to place another unit or any object on top of the receiver to prevent the ventilation holes on the top panel of the receiver from being obstructed. If doing so, the receiver may be damaged.
Notes
If the system is put in a rack, allow a space of at least 5 cm (1-15/16”) above and behind the unit.
Disconnect the AC supply lead from the AC outlet before connecting or disconnecting any component.
Antenna connection
(1) Supplied FM antenna
Connect the FM antenna wire to the corresponding terminal and direct the FM antenna wire to the direction where the strongest signal can be received.
(2) Supplied AM (MW/LW) loop antenna
Connect the AM (MW/LW) loop antenna wire to the corresponding terminals. Position the AM (MW/LW) loop antenna for optimum reception. Place the AM (MW/LW) loop antenna on a shelf etc., or install it on the rack or wall with screws (not supplied).
Notes
When static is still heard even after adjusting the position of the AM (MW/LW) loop antenna, try reversing the connection (top to bottom).
Do not place the AM (MW/LW) loop antenna on the unit. It will result in noise generation, since the unit is equipped with digital electronics. Place the AM (MW/LW) loop antenna away from the unit.
(3) External FM antenna
Use an external FM antenna instead of an indoor FM antenna if you need better reception. Consult your dealer.
(4) External AM (MW/LW) antenna
Use an external AM (MW/LW) antenna if you need better reception. Consult your dealer.
Note
When using an external AM (MW/LW) antenna, be sure to keep the wire of the AM (MW/LW) loop antenna connected.

In the event of a power failure or when the AC supply lead is disconnected.
The time display will go out, however, the clock will function for about 30 minutes without power supply. So you do not have to reset the time if the AC power supply is resumed within about 30 minutes. When the AC power supply is resumed after more than 30 minutes pass without power supply, the time display will flash on and off to indicate that the time must be reset.
Note
If this system is left for several minutes without setting the time after the AC power lead of this system is connected to the AC outlet, there may be a case that the display is turned into a demonstration mode.

Care of compact discs
Compact discs are fairly resistant to damage, however mistracking can occur due to an accumulation of dirt on the disc surface. Follow the guidelines below for maximum enjoyment from your CD collection and player.
Do not write on either side of the disc, particularly the non­label side. Signals are read from the non-label side. Do not mark this surface.
Keep your discs away from direct sunlight, heat and excessive moisture.
Always hold the CDs by the edges. Fingerprints, dirt or water on the CDs can cause noise or mistracking. If a CD is dirty or does not play properly, clean it with a soft, dry cloth, wiping straight out from the center, along the radius.

Automatic preset tuning
You can also make use of an automatic preset tuning function. By this function, this unit performs automatic tuning and stores stations with strong signals sequentially. Up to 40 stations are stored automatically in the same way as in the manual preset tuning method on the previous page.
1 Press the TUNER input selector button. 2 Press and hold the AUTO MEMORY button for about 2
seconds. * The MEMORY and AUTO TUNING indicators will flash.
This unit performs automatic tuning and received stations are programmed to A1, A2 ... A8 sequentially.
After the automatic preset tuning is completed
The display shows the frequencies of the first preset station (stored to A1). Check the contents and the number of preset stations by following the procedure of the section “To recall a preset station” on the previous page.
To recall a preset station
Simply follow the procedure of the section “To recall a preset station” on the previous page.
Notes
The automatic preset tuning search will be performed through all frequencies until 40 stations are stored. If the number of received stations is less than 40, the search will stop after searching through all frequencies.
With this function, only stations with sufficient signal strength are stored automatically. If the station you want to program is weak in signal strength, tune to it in monaural manually and program it by following the procedure of the section “To store stations” on the previous page.
You can replace a preset station by another FM or AM (MW or LW) station manually by simply following the procedure of the section “To store stations” on the previous page.
TUNING OPERATION
Fundamental rules of internal automatic preset tuning operation
Basically, FM stations are programmed onto area A, B and C, and AM stations are programmed onto area D and E (MW stations are onto D and LW stations are onto E) in that order automatically. * If, for example, the number of received FM stations is not
enough to fill up three areas (A, B and C), AM (MW or LW) stations are programmed closely from the preceeding empty areas. In such a case, AM (MW) stations are programmed from area B or C (and LW stations are from area C or D.)
* Moreover, one area is programmed with stations of the
same band only. If, for example, the last FM station is programmed to B4, B5–B8 will be programmed with no station, and AM (MW) stations are programmed from area C.
Memory back-up
The memory back-up circuit prevents the programmed data from being lost even if the AC supply lead is disconnected from the AC outlet or the power is cut due to temporary power failure. If, however, the power is cut for more than one week, the memory may be erased. If so, it can be re­programmed by simply following the Preset tuning steps.

TAPE DECK OPERATION (for KXW-S70 Double Cassette Deck)

General information
Do not use C-120 tapes, tapes with internal reels or poor­quality tapes, since they can cause malfunctions.
Before loading a tape into the cassette compartment, tighten the slack tape with a pen or pencil.
Tapes have removable tabs which prevent accidental recording or erasing from taking place. Removing the tab on the top left protects the side facing you from erasure. Cover the tab holes with adhesive tape to erase or record again.
This deck is a Double Cassette Deck with Automatic Reverse Function. DECK A: Playback only. DECK B: Playback or recording.
This deck features an auto tape selector. Just load the tape, and the tape formula being used will be sensed automatically.
This unit can play back metal tapes as well as normal or chrome tapes, and recording can also be done on metal tapes.
When covering erasure prevention tab holes, do not cover the chrome and metal detection holes. Otherwise, the deck will treat tape as normal tape.

Dolby B and C Type Noise Reduction
With cassette tapes, the most noticeable form of noise is high frequency hiss. To reduce this hiss noise, this unit has been equipped with a newly developed Dolby C noise reduction system in addition to its conventional Dolby B NR. Either type of noise reduction may be selected with the switch provided. Dolby B NR has a noise reduction effect of about 10 dB in the high frequency range. The corresponding figure with Dolby C NR is about 20 dB, but this is over the entire range where the human ear is most sensitive to noise (2 kHz to 8 kHz). Also, Dolby C NR has the same noise reduction effect at both high and low signal levels. In addition, Dolby C NR improves the tape’s MOL (Maximum Output Level). Dolby noise reduction is a 2 part process that acts both on recording and playback; be sure that the noise reduction button is set to the same position on record and play. * Noise in the source material cannot be reduced with the
Dolby NR system.

General information
Do not use C-120 tapes, tapes with internal reels or poor­quality tapes, since they can cause malfunctions.
Before loading a tape into the cassette compartment, tighten the slack tape with a pen or pencil.
Tapes have removable tabs which prevent accidental recording or erasing from taking place. Removing the tab on the top left protects the side facing you from erasure. Cover the tab holes with adhesive tape to erase or record again.
This deck is a Single Cassette Deck with Automatic Reverse Function.
This deck features an auto tape selector. Just load the tape, and the tape formula being used will be sensed automatically.
This unit can play back metal tapes as well as normal or chrome tapes, and recording can also be done on metal tapes.
When covering erasure prevention tab holes, do not cover the chrome and metal detection holes. Otherwise, the deck will treat tape as normal tape.
Do not press the OPEN/CLOSE button during playback or recording.

To stop playback
Press the stop button.
Note
When removing the tape, press the stop button, and then open the cassette compartment.
Direct operation
Even if an input source other than tape deck is selected, pressing the play button (or the fast wind button) will start playback (or fast winding) directly.
Tape Counter (LINEAR COUNTER) and RESET button
This unit is equipped with a tape counter which is useful for searching and locating a desired point on tape. The tape counter is displayed by minutes and seconds, though the displayed time is not so close to the actual elapsed time. (It will be close to the actual elapsed time by using a tape with the length of 60 minutes or 90 minutes.) Pressing the RESET button on the left side of the tape counter resets the tape counter to “0:00”.
REMAIN indicators
The remaining amount of the tape for the side now being played back is shown by the illumination of these indicators. According as the tape is played back, the indicators will go out one by one. When the tape playback nears the end of the side, the indicator at the left end flashes rapidly. However, when using a tape with large hubs, the tape may stop before the indicator flashes. This is because the error between the displayed time and the actual elapsed time becomes large when using these tapes.

At OFF TIME/time setting mode
[“OFF TIME” appears on the display, and soon it is changed to a time setting mode.] If necessary, set to the time when you want to finish the timer play (to turn this unit off) by using the HOUR button and the MINUTE button. Even if you do not set the time, it has already been set so that the timer play finishes after 1 hour.
* The TIMER button functions also in the time (ON
TIME or OFF TIME) setting mode.
3 If you will not use this unit until the timer play begins, turn
the power off by pressing the POWER switch or the TIMER button.
Note
If a timer play setting is made and the power is not turned off, the source set for the timer play will begin playing when the time comes in place of the source played at that time.
To cancel the timer play setting
After the timer play is finished, press the DISPLAY button to call the current time. While the current time is displayed, press the TIMER button so that “TIMER” goes out from the display. If it is not canceled, the system will be turned on at the same time every day, so it can be used as an alarm. However, if you will be out at that time, cancel the timer play setting. * Unless the AC supply lead is unplugged or there is a
power failure for more than 30 minutes, the time set on the timer will be retained until it is reset.
How to make time setting in the ON TIME or OFF TIME mode
For the hour:
Press the HOUR button to change the hour to a higher value. Press and hold to change continuously. To change the hour to a lower value, while pressing the TIME ADJUST button, press the HOUR button.

ACTIVE SERVO TECHNOLOGY (for Speaker System NX-S70 only)

Port
Cabinet
High­amplitude bass sound
Signals of low amplitude
Negative-impedance output drive
Active Servo Processing Amplifier
Air woofer (Helmholtz resonator)
Signals
The theory of the Active Servo Technology is based upon two major factors, the Helmholtz resonator and negative­impedance drive. Active Servo Processing speakers reproduce the bass frequencies through an “air woofer”, which is a small port or opening in the speaker’s cabinet. This opening is used instead of, and performs the functions of, a woofer in a conventionally designed speaker system. Thus, signals of low amplitude within the cabinet can, according to the Helmholtz resonance theory, be output from this opening as waves of great amplitude if the design is such that the size of the opening and the volume of the cabinet are in the correct proportion to satisfy a certain ratio. In order to accomplish this, moreover, the amplitudes within the cabinet must be both precise and of sufficient power because these amplitudes must overcome the “load” presented by the air that exists within the cabinet.
Thus it is this problem that is resolved through the employment of a design in which the amplifier functions to supply the signals. If the electrical resistance of the voice coil is reduced to zero, the movement of the speaker unit would become linear with respect to signal voltage, and, to accomplish this, a special negative-impedance output-drive amplifier for subtracting output impedance of the amplifier is used. By employing negative-impedance drive circuits, the amplifier is able to generate precise, low-amplitude low-frequency waves with superior damping characteristics, and these waves are then radiated from the cabinet opening as high­amplitude signals. The system can, therefore, by employing the negative-impedance output drive amplifier and a speaker cabinet with the Helmholtz resonator, reproduce an extremely wide range of frequencies with amazing sound quality and less distortion. The features described above are combined to be the fundamental structure of the Active Servo Technology.
