Tremolo/Chorus
The Electone's special tremolo is produced by a rotary
[ae speaker that actually spins just behind the rotary speaker
SLOW, grille on the side of the cabinet.
The tremolo selector is complemented by a continuous
tremolo speed control knob.
When the speed control is set to its maximum position,
TREMOLO SPEED 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),
TREMOLO the speed variation will be heard in the music.
If you wish an instant tremolo or chorus sound, be sure to
siwtch on that tablet well in advance of the speaker selec-
jaune tor. 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
CHORUS 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.
This tablet feeds Flute voices of the upper and lower
- manuals and preset Combinations to the rotary speaker.
TREMOLO
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 Voices are switched on simultaneously.
Manual Balance
This control governs the volume strength of the upper and 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 number of total tone lever settings (which
would ordinarily result in higher volume) on one of the two manuals.
Expression Pedal
Affect the emotional mood of every passage by letting you vary the volume continuously with your right
foot. This works within the range set by the master volume control.
Master Volume
This is determines the maximum volume obtainable by depressing the expression pedal.
