ELECTRIC GRAND CP-80
Yamaha's new CP-80 is a full 88-key electric grand piano that offers both the sound and touch
characteristics of an acoustical instrument,
Until now, the touring piano player has had to sit down to an unfamiliar instrument every time he
has performed. The action, the sound of the borrowed piano was always new and uncertain,
Also, many studios, clubs and stages didn’t have room for a full-size grand. Moreover, when the
acoustic piano had to be amplified, it was extremely difficult, if not impossible, to retain the true
sound.
But Yamaha has changed all that.
The exciting new Electric Grand CP-80 has the sound and feel of a full-size grand piano. Yet its
size and weight have been greatly reduced, making it easy to take it anywhere. Compact, sturdy
and loaded with versatility, the Electric Grand combines the artistry of musical craftsmanship with
the technical skills of electronic engineering.
To maintain the best quality performance of YAMAHA Electric Grand CP-80 for many years,
please read this manual carefully before you set tt up.
This manual contains the basic information and instructions for handling.

CAUTIONS
In case of using CP-80 abroad, it is required to
use an AC adaptor which is suitable for the
power supply voltage of the particular area.
4. Avoid exposure of CP-80 to direct sun, humidi-
ty, dust and so on, and place it on a level sur-
face free from any shock.
5.To remove dust or stains on the upper/the
bottom parts of the main body or on the key
board, use either neutral detergent or soft dry
cloth.
6. Make sure to operate CP-80 in the right way
according to the instruction so as not to appiy
unnatural force on switches, controls and
others.
7. Be careful not to catch your finger between the

This can be dangerous. supply of DC 16-20 volts. Never apply com-
mercial power supply voltage as it is.
2. 1f the model is moved with the damper pedal
attached, the function of the pedal may be
Impaired.
Fully assemble the model, move it to its instal-
lation location and then attach the pedal.
3. The CP-80 AC adaptor is especially designed
for this instrument, and is not interchangeable
with other power cords which can be purchased
at any electrical appliance shops. |f any other
AC adaptor is used, the internal electrical
circuit may be damaged and the electrical
shock may be received. Take sufficient care in
handling and storing this accessory, and again
make sure to use this special AC adaptor when
operating CP-80.

CONNECTION TO THE OTHER SYSTEMS
As YAMAHA Electric Grand CP-80 has the same functions as a grand piano, it offers enough
volume level for your own playing. But when playing it on stage or in the hall, make sure to
connect It to the speaker system.

t Sensitivity is extremely significant, since
an increase of only 3dB in sensitivity is
equivalent to doubling the amplifier power.
In other words, a 50-Watt amp used with a
speaker that is 308 more sensitive than an-
other speaker, will produce the same
sound level as a 100-Watt amp used with
the less sensitive speaker.
