Troubleshooting
Please note that the appearance of any of the following phenomena does not indicate
a mechanical failure of the Electone.
Phenomenon
Cause and Solution
A crackling sound is sometimes heard.
Noise may be produced when either an electrical appliance is turned ON/OFF or an electric power
tool, such as a drill, is used in the proximity of the Electone. In such case, plug the Electone into an
electrical outlet located as far as possible from the device that seems to be the source of the problem.
Interference from radio, TV, wireless radios, etc.
This is caused by the proximity of a high-power broadcasting station or amateur ham radio station.
Noise is produced in a radio, TV, etc.
Noise may be produced in such equipment if the Electone is located nearby. Use such equipment at
a location as far as possible from the Electone.
The
Electone
sounds
cause
surrounding
objects to
resonate.
Because the Electone produces many sustained sounds, resonance may be caused in surrounding
objects, such as cabinets or glass windows. If it becomes a problem, relocate the resonating objects or
lower the Electone's volume.
The volume of the selected voice varies with the position
played on the keyboard.
|
Because the intrinsic nature of electronic music instruments in general is to change timbre, it is
extremely difficult to eliminate changes in the volume of a voice at different keyboard positions. This
Electone is designed and adjusted to eliminate any performance-related problems. Its volume and
timbre also vary widely according to the installation site and system configuration of the Electone, the
position of the audience, etc.
Pitch sounds high for the pedal keyboard and low for the
upper and lower keyboards.
The sound of the notes is broken or seems to include
noise.
The pitch may seem particularly off when compared to the pitch of a piano. Because the harmonic
structure of a piano is very complex, the tuning of high and low notes must be performed by listening
to its harmonic overtones rather than to the actual sound. In contrast, an Electone is tuned according
to the actual sound, so the pitch of an Electone and a piano are inherently different.
This effect occurs mainly with the voices of wind instruments, and is deliberately provided to recreate
the characteristic sounds of the actual instruments. It provides instrument sounds with realistic
features, such as reed vibration or the breath noises for BRASS.
Only one sound is heard when two notes are simultane-
ously played on the pedal keyboard, or when a LEAD
voice is used by itself.
For practical performance reasons, this Electone has been designed so that one note can be played at
a time on the pedal keyboard or LEAD VOICES. If multiple keys are pressed only the highest note will
be sounded (high-note priority). (page 10)
Only seven
notes are heard when
eight notes are
simultaneously played on the upper or lower keyboard.
The pedal keyboard voice isn't sounded even though the
volume is properly set.
A Percussive voice is selected but is not sounded at the
keyboard.
A maximum of seven notes can be simultaneously sounded on the upper or lower keyboard.
SINGLE FINGER or FINGERED CHORD mode of AUTO BASS CHORD is active. Turn off the SINGLE
FINGER or FINGERED button at the panel.
Both the TO UPPER and TO LOWER buttons of the PERCUSSIVE section may be turned off. Or you
may have turned on the TO UPPER (TO LOWER) button but played the lower (upper) keyboard. Be
sure to turn on the Percussive button for the keyboard you wish to play. (™page 12)
The volume of the upper
keyboard is too loud in
comparison with the volume of the lower keyboard (or
vice versa).
The BALANCE button is set too far toward the UPPER (LOWER) side. During usual performances, set
Balance to the center level. (page 10)
A voice other than the displayed panel voice is sounded.
A VOICE MENU voice was assigned to the grey button with the lit lamp. To cancel the assignment and
restore the panel voice, press the grey button while pressing the ORIGINAL VOICE button at the
extreme right of the VOICE MENU. (pages 12 and 29)
When sounding a VOICE MENU User voice that was
assigned to a grey button, the resulting voice is not what
you expected.
USER VOICES 1 to 4 contain preset voices. If you perform a FROM PACK operation to transfer data
from an HS Series Electone to your Electone, however, the preset User voices may be replaced by the
User voices memorized in the Pack. If you wish to restore the preset User voices, turn off the POWER
switch then turn it back on while pressing either the rightmost button on the HE-8 MULTI-MENU or
the leftmost JAZZ ORGAN button on the HE-6 VOICE MENU. (page 26)
Basic Registrations cannot be called to REGISTRATION
MEMORY.
The MEMORY button was released after turning ON the POWER switch. To properly call the Basic
Registrations, turn ON the POWER
switch while pressing the MEMORY
button, then continue
depressing the MEMORY button for 1-2 seconds.
