TREMULANTS
Tremulants create changes in pitch (sharp and flat)
or
amplitude (volume).
The
use
of
tremulants
adds warmth to solo
or
small ensemble combinations and is useful
in
gospel and romantic music.
The
690
has a
regular
TREMULANT
which
is
useful for classical music.
It
also has a
FLUTE
TREMULANT
FULL
that affects all the flute voices
on
the organ.
This
tremulant has a wider
exc\lfsion (depth)
and
faster rate than other tremulant settings.
The
tremulants are adjustable for
both speed
and
depth
. .
It
is
recommended that these adjustments
be
made
by
A
Factory-
Trained
Techn~cJan.
EXPRESSIONPEDALS
The
pedal
in the middle controls the overall volume
of
the Swell Division.
The
pedal
on
the left
controls the overall volume
of
the Great and Pedal Divisions. These pedals are used
to
give variety
of
expression to the music played. Pressing the pedal forward increases the volume; drawing
back
decreases the volume.
When
the Expression Pedals are in use, the Expression indicators will light in green segments
(from bottom to top), as the pedal is depressed and more volume is created. The Expression
indicators are located to the right
of
the stop rail above the Swell manual, and are engraved
GT
and
SW.
(Note:
The
indicators will reflect the actual expression
of
volume, not necessarily the physical ·
position
of
the Expression Pedal.)
GREAT TO SWELLEXPRESSION COUPLER
The
Great to Swell Expression Coupler allows the Great and Swell Divisions to be expressed by
using the middle Expression Pedal.
CRESCENDO PEDAL
The
slightly raised pedal to the right
of
the Expression Pedals is the Crescendo Pedal, which
·gradually adds a factory pre-determined selection
of
stops as it is pressed forward.
The
Crescendo
Pedal does not affect the stops already set up on the organ, but merely adds to them. Stops added by
the Crescendo Pedal
do
not light.
When the Crescendo Pedal is in use, the Crescendo!futti indicator will light in green segments
(from bottom to top), as the pedal is depressed and more stops are added.
The
Crescendo{futti
indicator is located
to
the right
of
the stop rail above the Swell manual,
and
is engraved
CR.
TUTTI
There are times when a full organ registration is needed immediately.
The
690 is equipped with
a Tutti piston. Press the piston to tum on the Tutti, and press again
to
tum
it
off. When Tutti is on,
the Tutti piston lights, and the top segments
of
the
Crescendo!futti
indicator will light red.
The
Crescendo!futti
indicator is located to the right
of
the stop rail above the Swell manual.
