Yamaha CS01 User manual

INTRODUCTION
Thank you for choosing aYamaha CS01 Micro-Mono-
phonic Synthesizer. The CS01 incorporates advanced
synthesizer technology and features developed for the
renowned Yamaha CS-series synthesizers with the added
convenience and versatility of alightweight, exceptionally
compact format. Further, the CS01 has abuilt-in amp and
speaker, and can be run on either batteries or an optional
AC adaptor unit. The CS01 imposes no limitations on
where or when you play. Outdoors, at home or on stage,
the Yamaha CS01 gives you great Yamaha synthesizer
sound and versatility.
We urge you to read this owner's manual thoroughly in
order to make the most of your CS01 Micro-Monophonic
Synthesizer.

CAUTIONS
*INSTALLATION/LOCATION
Do not use this unit in any of the locations mentioned below, as this
may impair the sound quality or result in failure or breakdown.
*Location near awindow where the unit may be exposed to direct
sunlight or other extremely hot locations.
*Locations with aparticularly low temperature.
*Locations exposed to high levels of moisture or dust.
*Locations susceptible to vibration.
•DO NOT USE FORCE
Do not force when using the switches or knobs.
•TAKE CARE OF THE POWER CORD
In order to prevent cord breakage and shortcircuits, take hold of the
plug, not the actual cord, when disconnecting it from the power outlet.
If the unit is not to be used for prolonged periods of time, disconnect
the plug from the power outlet.
•MOVING THE UNIT
Make sure that you disconnect the power cord and detach connecting
cables to other equipment before moving the unit.
•CONNECTING AND DISCONNECTING OUTPUT CORDS
If the output cords are connected or disconnected when the volume
level of the amplifier should always be set with care, as the application
of excessive input to the amplifier may cause damage to the amplifier
or speakers. Before connecting or disconnecting the output cords to the
other equipments, make sure to switch off each power switch.
•MAINTAINING THE UNIT
Do not wipe the unit with benzine or thinner, and do not use aerosol
sprays in its vicinity. Always use asoft cloth to wipe the unit.
•KEEP THIS MANUAL
Keep this manual in asafe place for future reference, and refer to it
frequently until you are fully familiar with your CS01.
•THUNDERSTORMS
Remember to disconnect the power plug from the power outlet when-
ever there is athunderstorm in order to prevent accidents resulting
from lightning.
•OTHER APPLIANCES
Since your CS01 incorporates aconsiderable amount of digital circuitry,
it is advisable to use it where it will not be influenced by electromagne-
tic radiation from appliances such as televisions, radios, etc.

SETUP PROCEDURE
POWER SUPPLY
1.Open the battery compartment on the bottom of the unit.
Bin dSlide forward
2. Observing polarity as shown in the illustration, insert six batteries
into the battery compartment.
Be sure battery polarity is correct (+, -)
eK®
When you intend to run the CS01 on batteries, make sure the optional
PA-1 AC adaptor is unplugged from theCSOl external power jack. The
batteries are automatically disconnected when the PA-1 is plugged into
the CS01 power jack.
BATTERY LIFE
Battery life depends to some degree on the type of batteries used and
volume level, but generally, 6hours of continuous use can be expected
when using the built-in amp and speaker at maximum volume. Battery
life is approximately 16 hours when using an external amplifier.
BATTERY REPLACEMENT
The CS01 features abuilt-in low-battery warning circuit. When battery
voltage drops below the usable level, the CS01 power indicator LED
will flash on and off. When this occurs, all the batteries should be
replaced before battery operation is continued.
3. Close the battery compartment.

BATTERY OPERATION
3Install batteries as shown in the illustrations.

Flash on and off
*Be sure to replace all batteries with new ones at one time. Used
batteries and new batteries must not be mixed.
*If batteries are not to be used for an extended period of time, they
should be removed from the battery compartment to prevent
damage due to battery leakage.
OAC ADAPTOR
The optional PA-1 AC adaptor plugs into the CS01 DC IN 12V jack.
Side panel
The batteries are disconnected when the PA-1 is in use, so no battery
discharge will occur.
Using AC adaptors other than the PA-1 may result in damage to the
CS01 due to incorrect polarity. „
Polarity is reversed in some adaptors

CONNECTING TO AN EXTERNAL AMP
When using the CS01 with headphones or an external amplifier rather
than the built-in amplifier and speaker, connections must be made via
the CS01 side panel.
When aplug is inserted into either the PHONES or LINE OUT jack, the
internal speaker is automatically shut off.
OPHONES (HEADPHONE JACK)
This jack accepts either apair of monaural keyboard monitor head-
phones or any standard pair of stereo headphones (output is
monaural).
©LINE OUT
Provides output to an external amplifier or mixer. This output jack
cannot be connected directly to an external speaker. Amusic
instrument amplifier or audio amplifier must be used.

BASIC SETTING
TURNING THE INSTRUMENT ON
POWER/VOLUME
This control serves the dual function of power switch and volume
control. If rotated clockwise the unit is turned ON and the indicator
LED will light. Volume increases as the control is rotated towards
the "10" end of its scale.
The CS01 is amonophonic synthesizer (high-note priority). If more
than one key is pressed at atime, only the sound of the highest note
played will be heard.
OTurn the power ON, and set the CS01 controls as shown in the
illustration. You should now be able to hear notes played via the
CS01 's speaker.

SOUND CREATION I/VCO
THE VCO BLOCK
The VCO (Voltage Controlled Oscillator) is the basic sound source of
the CS01 producing asignal at the pitch determined by the keyboard.
RANGE SELECTION
OFEET SELECTOR
This selector determines the range of the CS01 keyboard. The
CSOI's 32-key keyboard covers arange of 2-1/2 octave (F2--C5
when the FEET selector is set to 8). The FEET selector permits
shifting the keyboard range over afive octave range.
If this selector is set to WN, white noise is produced. By applying
filtration to this white noise using the CS01 VCF, the sound of surf,
wind or waves can be created.
Try switching the FEET selector through its settings while playing a
note on the keyboard.

waveforms have different types (odd or even) and different numbers
of harmonics, and therefore different sounds.

SOUND CREATION U/VCF
The CS01 offers four different waveforms plus apulse width modula-
tion feature as shown in the chart below.
Waveform Name Characteristics
ATriangular wave Subdued tone. Ideal for flute sounds.
r\ Sawtooth wave Bright tone. Perfect for violin and
other string sounds or brass instru-
ment sounds.
ru Square wave "Woody" tone. Great for clarinet.
ru Rectangular
wave Vibrant tone. Trumpet, oboe, etc.
ru PWM Thick, rich sound. Chorus effect.
The PWM SPEED ©and GLISSANDO ©controls will be described
in Sound Creation V/Other Functions.
All the controls described so far determine the basic CS01 sound. In
order to fully understand the operation of the VCF (described next),
return the controls to their Basic Settings (refer to the illustration on
the previous page).
VCF BLOCK
The VCF (Voltage Controlled Filter) alters the tonality of sounds
created by the VCO by cutting off certain harmonics.
CREATING THE DESIRED TONALITY
FREQ. CUT OFF LEVER
Determines the cut off frequency of the VCF.
Level Basic sound with harmonics
Cutoff point —
-
Setting this control at the "H" end of its scale permits all the upper
harmonics of the basic sound to pass, thereby creating abright tonality.
Moving the control towards the "L" end of the scale gradually cuts off
more and more upper harmonics, creating arounder, softer tonality. If
the FREQ. CUT OFF lever is set all the way to "L", the fundamental
may be cut off and no sound will be heard.

©RESONANCE SELECTOR
Set to the "H" position, frequencies near the filter cut off frequency
are emphasized for a"sharper" sound.
