QUICK SETUP INSTRUCTIONS iVIPORTANT INFORMATION INTRODUCTION
1. Physically assemble the legs (see instructions on
page 2} or set the CS-80 atop asturdy surface,
allowing space for air to circulate through the top
and bottom cooling vent panels.
2. Plug in the FOOT SWITCH and FOOT PEDAL
(CONTROLLER) at the rear panel; be sure to
insert the plugs in the proper jacks.
3. Using guitar cord(s), connect the CS-80 Rear-Panel
Output Jack(s) to aprofessional, wide-range speaker/
amplifier unit. LEFT and RIGHT may be used for
2-channel systems, or GENERAL (mono) for single-
channel systems, such as guitar amps. (Hi-Fi music
systems are not recommended for this application.)
Alternately, connect apair of stereo headphones to
the PHONE JACK below the right side of the key-
board.
4. Open the storage panel below the synthesizer,
remove the power cord, and plug it in to asuitable
AC power main.
5. Set the rear-panel HIGH/LOW switch to LOW, turn
on the CS-80 power, and set all controls at nominal.
If the volume is too low, even with the VOLUME
control all the way up and the FOOT PEDAL flat
(maximum level), then switch HIGH/LOW to HIGH.
6. Try various preset patches by touching different
TONE SELECTOR buttons [3] and moving the MIX
l-l Ilever [4] up or down to point at the row cor-
responding to the selected preset. Adjust BRIL-
LIANCE [7] as you do this. See pages 24 through
30 for additional panel-programmed patches.
1. Always allow space below and above the synthesizer
for air to circulate through the vent panels. This is
essential for proper cooling of the circuitry. If the
vents are blocked, tuning instability and component
failure may occur.
2. Always plug the FOOT SWITCH and FOOT PEDAL
(CONTROLLER) into the proper jacks. THE
SYNTHESIZER WILL NOT WORK AND MAY
REQUIRE REPAIR.
3. Avoid exposing the synthesizer to direct sunlight or
very high humidity environments.
4. Clean the keys and plastic parts with Yamaha Key
Cleaner creme polish, or with amoistened soft cloth.
Never use abrasives, cleansers, waxes or solvents,
which may dull the keys or chemically attack the
finish.
5. Leave internal adjustments to qualified Yamaha
service personnel, if you open up the unit and reset
any trimmers, the unit may require acomplete re-
voicing by Yamaha.
6. The EXT IN jack is designed for audio, line-level
signals. Never connect it to an AC power line, or to
aspeaker-level output. Also, do not connect any
CS-80 output to the EXT IN jack, as this may cause
feedback and possible damage to your equipment.
7. The CS-80 weighs approximately 100kg
(220 lbs.). When setting it up or transporting it, at
least two people should do the lifting.
8. While the CS-80 is constructed with an integral case
of sturdy plywood and metal-reinforced corners, we
recommend the use of an additional travel case for
cartage, preferably built to ATA-300 specifications.
(See page 48.)
The CS-80 is easy to play. While it is ahigh-
technology musical instrument, you don't have to
know about electronics to understand how to use the
CS-80. We do recommend, however, that you read this
manual thoroughly, and periodically refer back to it as
you learn the instrument, if you're in ahurry, check
the Quick Setup Instructions on this page.
The Yamaha CS-80 is aunique 8-note polyphonic
synthesizer, one which places the entire realm of
musical expression at your fingertips. The CS-80 is a
true musical instrument, not merely a"special effects"
tool. The sounds are infinitely variable, and, because
the keyboard is both velocity and pressure sensitive,
you have true dynamic control over your music.
The CS-80 will give you an incredible variety of
electronic sounds, but it goes further than that. Having
aCS-80 is like having asymphony orchestra to choose
from. Largely due to touch sensitivity (keyboard
dynamics), Yamaha has overcome atraditional
challenge for synthesizers, namely, the difficulty
in creating the sound of an acoustic instrument. For
example, if you've ever tried to create a"violin" on
the keyboard of most synthesizers, you probably found
the result too "electronic." While you may have
achieved agood basic violin sound, when you played
it, there was something missing ...but what?
Ask agreat violinist to play the note "G" 8con-
secutive times (not an open string). Request that he
make them absolutely identical in pitch, timbre,
volume and every other possible variable. You'll
discover that he cannot do it ...fortunately. Much of
the charm of amusical performance is that it is not
"textbook perfect," and this is why your well-pro-
grammed synthesized violin did not sound "right" to
you. However, your CS-80 is another story.
Touch response makes all the difference. You can
set up a"violin" so that the way you press akey
changes the vibrato, timbre, pitch, volume, brilliance
... the whole essence of the sound. With this kind of
expressive capability you too may not exactly
duplicate 8consecutive notes. However, the sound
you do achieve will be much more realistic and musical
than has ever before been practical with an electronic
musical instrument.
The CS-80 is the first of awhole new generation of
performer-oriented electronic musical instruments.
Only Yamaha, the world's leading manufacturer of
fine musical instruments and high-quality sound equip-
ment, could have built it.
