Congratulations
Congratulations on becoming an owner of the Yamaha CE25 Combo Ensemble. Despite
its light weight and compact size, the CE25 offers remarkably natural, “acoustic” sound
through the use of advanced FM tone generator technology. The CE25 is ideal not only
for the professional keyboard player, but also for use at home as the family keyboard.
Please be sure to read this manual thoroughly in order to gain maximum performance and
enjoyment from your CE25 Combo Ensemble.

Precautions
LOCATION CONNECTION
Avoid placing your CE25 Combo Ensemble in direct
sunlight or close to a source of heat. It is also important
to avoid locations in which the instrument is likely to be
subjected to vibration, excessive dust, cold or moisture.
Be sure to unplug your CE25 Combo Ensemble if you
will not be using it for an extended period of time.
HANDLING
Avoid applying excessive force to the instrument's knobs
and switches.
POWER CORD
Always grip the power plug directly when unplugging.
Removing the power plug from the wall socket by pul-
ling on the power cord can result in damage to or
shorting of the power cord.
Be sure to unplug your CE25 Combo Ensemble if you
will not be using it for an extended period of time.
RELOCATION
When moving the CE25 Combo Ensemble once it has
been set up, be sure to disconnect all cords that connect
the instrument to other equipment. This will help to
prevent accidental damage to or shorting of intercon-
nection cables.
Follow the “CONNECTION” instructions given in this
manual carefully when setting up your CE25 Combo
Ensemble. Connection errors can lead to serious damage
to the instrument, amplifier and speakers.
CLEANING
Do not use solvents such as benzine or thinner to clean
your CE25 Combo Ensemble, as these may cause
discoloration or staining of the instrument's exterior.
Use a soft, dry cloth.
SAVE THIS MANUAL
After studying this manual thoroughly, it should be
stored in a safe place for future reference.
LIGHTNING
In the event of an electrical storm, the instrument's
power cord should be unplugged to eliminate the possi-
bilitv of serious damage.
OTHER APPLIANCES
Use vour CE25 Combo Ensemble where its digital cir-
cuitrv cannot be influenced bv electromagnetic radiation
from appliances such as televisions, radios, etc.

Connections
The CE25 Combo Ensemble does not have an internal power amplifier. An external amplifier/Speaker
system must be used.
*No external amplifer is required for headphone operation.
Power Cord
Insert the CE25 power plug into the most convenient
AC wall outlet.
* VOLTAGE SELECTOR (GENERAL MODEL ONLY)
e |f your CE25 has a voltage selector on the bottom
cover, check that it is set to your local voltage
before plug in. If not properly set, turn the select-
or to the correct voltage indication.
External Amplifier/Speaker Systems
The CE25 can be connected to an external power
amplifier and speaker system, an integrated keyboard
amp/spaker, a mixer/PA system, or a stereo amplifier.
* Do not connect the CE25 to the microphone or
phone inputs of a stereo amplifier or mixer.
© LINE OUT
Connection to an external amplifier is accomplished
via the leftmost (LINE OUT) jack.

This is the CE25 “tuning” control. Moving this lever
towards the “+” end of the scale raises the overall
pitch, while noving towards the ''—' end of the
scale lowers overall pitch. Control range is from 436
+ 2 to 447 + 2 Hz (A3).

Kevboard
The CE25 kevboard covers 4 octaves with 49 kevs.
The overall range of the kevboard depends on the
voice selected.
Double-Stroke Key
The CE25 keyboard action has two stages. If a key is
pressed normally, it will stop at the first stage. If the
same key is then pressed even further you will initiate
the second stage. This double-stroke key feature gives
the CE25 its unique touch response capability.
Please refer to the Touch Response section of this
manual for further details.

Sound Variation
The CE25 Combo Ensemble offers 20 polyphonic voices that permit simultaneous output of up to 8
notes, anv of which can be selected at the touch of a button. Thanks to highiv advanced FM voice
generation technology, all of the CE25's voices are exceptionally real and natural.

Different sounds are made up of completely dif
-ferent spectrums. In other words, each musical
sound is actually made up of a unique combination
of many discreet frequencies.
FM {frequency modulation) is familiar to most of
us in the form of FM radio broadcasts. The vibrato
effect in music is also actually a result of frequency
modulation. The FM tone generator applies fre
-quency modulation technology to the audible
frequency range to generate music waveforms
containing many discreet frequency components,
the individual levels of which vary throughout the
duration of a note. The result is remarkably
“natural” sounds closely approach the timbre of
conventional acoustic instruments.
The FM tone generator has made it possible to
create new, delicately natural voices that were un
-attainable with prior technology (i. e. conventional
synthesizers, electronic organs, etc.), offering con
-siderably broadened expressive capability.

BRILLIANCE SYMPHONIC DEPTH SENSITIVITY
© BRILLIANCE
This control adjusts the overall tonality of all the
CE25 voices. Setting this control towards the “MAX”
end of the scale produces a brighter, crisper sound
quality, while setting towards the “MIN” end of the
scale creates a softer, rounder tonality.
@ SYMPHONIC
This effect creates a “thick,” multi-instrument sound.
@ THE SYMPHONIC effect is automatically turned
on whenever the STRING 1—3 or ORGAN 1 are
selected,
© SYMPHONIC DEPTH
This cotrol permits adjustment of the depth of the
SYMPHONIC effect.
Vibrato & Touch Response
One of the most advanced features of the CE25
is its remarkable touch response capability. This
function permits control over tonality, volume
and vibrato depth according to the pressure
applied to the instrument’s keys. This means
that the CE25 provides the same type of dy-
namic expression capability as an acoustic
piano, and greater realism can be added to wind
and string instrument sounds by appropriate
variation of vibrato depth.

"Normal" touch response and vibrato parameters
have been preset into the CE25 by Yamaha music
specialists. These parameters are activated by pressing
the PRESET button, so you don't have to set the five
touch response and vibrato parameter levers yourself
to take advantage of their extensive expressive
capabilities.

when the instrument is initially turned on.
@ The five touch response (SENSITIVITY) and
vibrato controls have no effect when the PRESET
button is ON. If you wish to set up your own

SET button must be turned OFF.

SENSITIVITY
These controls adjust the sensitivity of the touch
response function. Setting these controls to-
wards the ''Max'' end of their scales increases
sensitivity resulting in a greater change in sound
with lighter pressure.
© TONE INITIAL
Adjusts the initial note attack. If this lever is moved
towards the "MAX" end of the scale, a lighter key
stroke produces a less prominent note attack while
a heavier key stroke produces a stronger note attack,
TONE INITIAL effect

© TONE AFTER
Adjusts the sound variation produced by key pressure
variation after initial attack. If this lever is moved
towards the “MAX” end of the scale, varying the
pressure applied to a held key produces a larger
variation in the sound.
e With voices that decay after initial attack—such as
PERCUSSIVE 1-6—the setting of the TONE
AFTER lever will have little effect.

Modulation
© VIBRATO AFTER
Adjusts the amount of variation in vibrato depth
caused by varying key pressure. The speed of the
vibrato effect is determined by the VIBRATO SPEED
lever.
If this control is set towards the “MAX” end of the
scale, increasing key pressure results in a correspond-
ing increase in vibrato depth.

also be used independently of the touch res-
ponse feature using the following 3 controls.

Adjusts the depth of the vibrato effect. Moving this
wheel towards “MAX” produces a deeper vibrato
effect, while moving to “MIN” produces a shallower
vibrato effect. Set all the way to ''MIN'' cancels the
vibrato effect.
@ VIBRATO DEPTH can be controled even when
the PRESET switch is on.
© SPEED
Adjusts the speed of the vibrato effect, Setting
towards the "FAST" end of the scale produces a
faster vibrato effect. The speed control range is from
approximately 4 to 10 Hz.
e The touch response vibrato speed is also adjusted
using this lever.
© DELAY
Adjusts the length of time it takes for the vibrato
effect to be applied after a key has been pressed. This
effect — known as delayed vibrato — creates an
exceptionally realistic vibrato sound.
The further this control is set towards the “MAX”
end of the scale, the longer it takes for the vibrato
effect to be applied.
