Keyboards
The DK-40C has five keyboards. The upper four are called ‘‘manuals” (“‘solo”, “portamento”, “upper”
and ‘‘lower’’), and the bottom, for the feet, is the “pedals”.
Upper Manual 4 octaves c ~ ca Solo Manual 3 octaves C ~ C3
Lower Manual 4 octaves C~ c3 Portamento 2% octaves f ~ c3
Pedals 1 octave Cı-C
The Electone is designed to permit playing the melody on the upper manual with the right hand, the
chords on the lower manual with the left hand, and bass note on the pedals with the left foot. For
special selections the solo manual can be used to provide a melodic line with its own exciting voices. Use
the portamento manual to create a range of unique sounds, pressing or sliding your finger(s) up and
down. All keys and pedals are arranged in the layout shown below. Each white key has a name (from
C to B), and the blacks are sharps or flats.

Note: It should be noted that precedence is to the higher note if two

hallada
All four Solo voices have been specially designed for brilliant realism. Each voice is set via its selector
tablet at the left of the Solo manual.
Note: The four voice tabs, i.e., Violin, Clarinet, Trumpet and Saxophone, control voices which purposely cannot
produce
chords;
if
two
or
more
keys
are
pressed
simultaneously,
only
the
higher
will
sound.
Please
also
note
that solo voices cannot be combined. If two or more voice selector tabs are pressed, the one to the right takes
precedence.
TOUCH VIBRATO
This world-famous Yamaha exclusive gives to the organist the same expressive fingertip vibrato enjoyed
by the violinist. With this effect, vibrato can be applied to any solo note by the lateral vibration of the
hand, and its speed will correspond exactly to the hand’s vibration.
FUZZ
Fuzz is frequently used on the electric guitar.
This Fuzz effect affects each tone of the Solo manual by switching the Fuzz selector “ON.”
ATTACK WAH-WAH
Works like Upper manual wah-wah for solo tones.
SOLO VOLUME CONTROL
This permits a variety of manual balance settings.
Portamento Manual
The Portamento manual produces continuous pitch shifts just like those produced when the finger
slides up and down a violin string. The 2% octave range becomes higher toward the right.
Note: There are four Portamento voice selector tabs and except for the Astro tab they can all be combined with each
other. If the Astro tab is set it cancels all the other.
PORTAMENTO VOLUME CONTROL
This permits a separate volume control.

a>
Tone Levers
On the panel above the solo manual and selectors is a series
of tone levers which control the voices (instrument sounds)
which will be heard when the keys are depressed, as well as
many of the effects. They are divided into groups for upper,
lower and pedals, so that different registrations can be set
for each.
Upper Manual Levers 12 voices
Lower Manual Levers 5 voices
Pedal Levers 3 voices
PITCHES OR FOOTAGES
The DK-40C has five different pitch levels, indicated by
the numbers 16’, 8°, 5%”, 4’ and 2%’. These are standard
musical abbreviations showing the tone's pitch in relation
to the fundamental (written note), An 8’ tone will sound
just as it has been written. As the numbers increase, the
tones lower. A 16' tone (meaning that the wave length of
the vibrations are twice as long as 8’, or half as fast) will
provide a tone exactly one octave lower than the written
note. Similarly, 5%’ tones are a fifth higher than the written
note, 4° tones one octave higher, and 2%’ tones one octave
and a fifth above the fundamental. Tones at octave intervals
from the written notes are “consonant harmonics,” while
all others are “dissonant.”*
To the left of the lower manual are eight Upper Preset Tone selectors (seven tones plus Cancel). These
on/off switches are special tonal blends that most closely resemble the instruments they name
(Accordion, Piano, Hawaiian Guitar, Banjo) as well as three special preset combinations.
Since these buttons are factory preset, they automatically cancel all other upper manual tone lever
settings. This lets you switch back and forth. In addition, precedence is to the right. This means that
if two or more buttons are pressed, the one to the right will take effect. To switch from one button to
another it is not necessary to first press the cancel button.
Note: Upper Sustain control lever does not work with the Accordion, Piano, Hawaiian Guitar and Banjo preset selectors,
ORGAN PRESET ENSEMBLE
This lever controls the effect which adds the upper tone to the upper preset tone. (Accordion, Piano,
Hawaiian Guitar, Banjo)

Brilliance
With this single, continuously-variable control you can pin-
point the degree of overall softness or clarity desired for
any mood of music.
Vibrato,Vibrato Speed
Vibrato is an emotional wavering applied to a tone most
noticeable in the trembling left hand of violinists and cellists.
It can add a great deal to the emotional depth of a passage,
especially string voices. The Vibrato lever provides conti-
nuous adjustment of this effect's depth, while Vibrato Speed
lets you continuously set the speed.
Repeat Speed
Cuts and repeats each note just like the double-strumming
effect of a mandolin. The lever provides continuous speed
adjustment to create a full variety of different moods.
Affects upper manual notes only.
Reverb
The reverberation effect, which makes your playing sound
full and rich, as if you were playing in a large hall, can be
adjusted continuously and smoothly to suit your taste.
U 8’, 4’S i
pper ð, ustain
When this is switched on, the sustain effect is evoked. As
the name of the tab implies, only 8’ and 4’ tones are affected.
The length of such sustain is set by the Upper Sustain con-
trol.
Note: When combined with Upper Percussive 4’, all sound is cancelled.
Sustain
UPPER, PEDAL SUSTAIN
These controls provide continuous adjustment of the sustain
effect on the upper manual and pedals concerned. For the
pedals, this is the only sustain control, and it affects all pedal
tones with the exception of Bass Guitar, while for the upper
manual this control is only a length adjustment. Length
of upper sustain is controlled by the upper sustain control
knob as explained beside.

Upper 8’,4’ Attack |
This tablet provides an effective rhythmical element, much
like that of a string bass played pizzicato. It is particularly ;
impressive in rhythmic works, and give greater definition |
to the beginning and end of notes. The 8’, 4’ Attack tab |
affects all upper manual 8’ and 4’ voices.
Glide (FOOT SWITCH SELECTORS)
While the foot switch is pushed when the Glide selector is
on, pich will be lowered one half tone.
Upper Percussive
Changing the beginning of some or all notes can do wonders
for lively selections. Your Electone’s percussive effects
provide subtle but important shading at the moment each
note is heard. The special popping 4’ and 2%’ percussive
drive can be smoothly blended into all upper manual tones
with two variable levers, and a separate lever regulates the
length of decay for this effect.
Note: If Upper Percussive 4’ is set at the same time as Upper Sustain,
no sound will be heard.
With percussive, use a staccato fingering. Each note should be
played cleanly; slurred notes will diminish the percussive impact.

Manual Balance |
This control governs the relative strength of the upper and i
lower manuals. It is normally left in the center position, but
can be shifted to stress the melody or accompaniment in a
selection or passage.
This control can also be used to compensate for a higher
il == lila number of total tone lever settings (which would ordinarily
Upper Manual lower Manual result in higher volume) on one of the two manuals.
Expression Pedal
ON Affects the emotional mood of every passage by letting l
Foot Switch M Ki you vary the volume continuously with your right foot. f
Works within the range set by the master volume control.
Master Volume
This control determines the maximum volume obtainable by
Expression Pedal depressing the expression pedal.

The Electone’s special tremolo is produced by a rotary speaker that actually spins just behind
the rotary speaker grille on the side of the cabinet.
Tremolo selector is complemented by a continuous tremolo speed control knob.
TREMOLO SPEED
TREMOLO
TREMOLO
When the speed control is set to its maximum position,
the Tremolo will turn the speaker at normal revolution.
The Chorus will turn it at one revolution. Once either
tablet is switched on, it takes several seconds for the rotary
speaker to attain the standard speed. This is also true when
switching to a slower speed (Tremolo to Chorus), the
speed variation will be heard in the music.
If you wish an instant tremolo or chorus sound, be sure
to switch on that tablet well in advance of the speaker
selector. For special selections you can use this speed
variation by switching the speaker on first, the Tremolo
or Chorus switch later.
Note: Only Tremolo is produced when Tremolo and Chorus are
switched on simultaneously.
UPPER VOICE
Lets you divert upper manual voices from the main to the
rotary speaker.
LOWER VOICE
Does the same for lower manual voices.
FLUTE SPLIT
This tablet feeds Flute voices of the upper and lower
manuals and preset Combinations to the rotary speaker.
Combined with other manual voices through the main
speaker it creates a rich, singing blend.
Note: Only Flute Split is produced when Flute Split and Upper or
Lower Voice are switched on simultaneously.

FINGER CHORD STANT
CHORD
C chord
The DK-40C is equipped with a “Fun Block” section of
five buttons which can be used in conjunction with the
Auto Rhythm section (see p. 9). It enables you to play
a variety of alternating bass chord rhythms, with the pedal
and chords automatically matching the melody notes,
simply by holding down either a single lower manual key
or a lower manual chord, according to which fun block
button you press. From your very first keyboard attempt,
the fun block feature will let you sound like a pro, making
full rhythmic use of the lower manual and pedals. Here is
how it works.
Note: When the Auto Bass/Chord section is used, the tone color of
the lower manual voices will change from Horn 8’ to Piano,
and from Cello 8’, Cello 4’ to Guitar.
Flute voices are not affected. If it is set on it will sound con-
tinuously for any key held down. Use it to soften the mood
of the Auto Bass Chord accompaniment.
SINGLE FINGER CHORD (THE EASY PLAY WAY)
e Set the tone levers for the tones you want on the lower
manual both Piano and Guitar sounds are available); use
either or both levers to adjust the Auto Bass Chord
tone color and volume in the normal way.
e Match the setting of the Pedal tone lever to the lower
manual tones.
e Select a rhythm pattern and push the corresponding
button until it clicks and stays down.
e Set the Rhythm Start switch on.
e Adjust the rhythm tempo and volume.
e Press the Single Finger Chord button.
Now, if you press a C key on the lower manual, a C major
chord will play in an alternating pattern which matches the
rhythm pattern and tempo set.
As long as the key is held down, the bass chord rhythm
continues. When the Black-key pedal is pressed, the chord
changed from major to minor, and when released, the chord
returns to major. When the White-key pedal is pressed,
the chord changes from major to seventh, and when released,
the chord returns to major. When both Black- and White-
key pedals are pressed, a minor seventh results.
Note: The bass note will play the root and fifth of any chord pressed,
except when the Jazz Rock rhythm is used; in that case the
bass sounds the root only.

TONE CABINET SOCKETS
This socket is on the rear panel. Use it to con-
nect a Yamaha Tone Cabinet, without any
rewiring required.
SPLIT GENERAL

Electone is not out of order If...
Tree the set does not go on when the power switch is
turned on. Check the following.
Is the AC plug fully inserted into the electric wall outlet?
Reinsert it to be sure. Is there power coming from that
outlet?
If there is power in the outlet but the Electone does not
play, unplug the cord and contact your Yamaha dealer.
There are NO USER SERVICEABLE PARTS inside.
2...... a sound should occur the instant you turn on the
switch.
This merely indicates normal operation consequent on a
surge of electricity in the main amplifier.
Inc occasional unpleasant static occurs.
In the majority of such cases, the cause can be traced to
the turning on or off of refrigerators, washing machines,
electric pumps or other household appliances. Electrical
faults in a neighboring outdoor neon sign may also be to
blame.
If the cause is a fault in a neon or fluorescent lighting
fixture, it should be repaired. When the cause is un-
known, or in case of doubt, contact your Yamaha dealer.

4. cu. the Electone reproduces radio or TV signals.
If there is a powerful transmitter such as a radio station
in the vicinity this can occur. Contact your Yamaha
dealer.
BL cies pedal notes sound too high, upper keyboard’s notes
too low. This is especially noticeable when comparing
the Electone with piano. Piano tones are combinations of
harmonics and must interact with their surroundings,
while Electone harmonics are simpler (multiples of the
fundamental tone), requiring the Electone to be adjusted
differently at the assembly stages.
Pog rattling (sympathetic vibration) occurs.
All materials have critical resonance frequencies at
which they vibrate. The Electone’s continuous tones
will naturally cause other objects (windows, shelves, etc.)
to vibrate.
