( )Turn on the switch "Heavy" (also called "Celeste"). The intensity of the vibrato
should increase.
( ) Turn on the switch "Soft" only (also called "Chorus"). The vibrato becomes
less intense.
( ) Turn on both "Heavy" and "Soft". The result is an intensified vibrato (like the
one you hear when holding your ear very close to a rotating speaker). Thus
"ultra-heavy "vibrato is disabled automatically (and reduced to "normal heavy") at
the chorale speed.
( ) Turn on the switch "Whirl/Choir" only. The Wersivoice is now in its voice-
multiplying
mode (also called string orchestra mode). The incoming voices
(coming from single instruments) are transformed into sets or choirs of voices.
The two intensity switches perform similar duties as in the "Whirl" mode. The
"Fast/ Chorale" switch, however, is disabled. For more details, refer to the
manual A M 4 65 "Wersivoice".
3.12 Testing of the Swell Pedal and Reverb
( ) Push the connector of the harness GO 1 onto the pins of "Plug 1" of the
preamplifier (board VV 1). Refer to Fig. 36 for proper orientation of the connector.
( ) W 1 T only: Plug the swell pedal cable into the receptacle on A P 2.
( )Test the volume control operation of the swell pedal while playing.
( ) Take the swell pedal back all the way (up). Adjust the trim pot "Null" o n VV 1
for minimum volume.
( ) Depress the push button " Reverb I" and push the swell pedal down. Hit a
chord briefly and observe the reverb.
( ) Release " Reverb I" and depress " Reverb II". The reverb time should be
lengthened.
Adjust the trimpot P 2 on V V 1 such that the longest reverb (" Reverb I and II"
depressed) suits your personal taste. Our recommendation: center of rotation.
( ) Set the treble control P 3 on V V 1 (top) and the bass control P 4 (center) to
the center of rotation. Later on, you may want to re-adjust these controls to
match the organ sound to the room acoustics.
( ) Set the trim pot P 5 on VV 1 (bottom) for the highest desired volume from your
speaker when the swell pedal is fully depressed and when you play with "full
organ':
3.13 Testing of the Special Effects
The testing and adjusting of this building block ;s described in the manual A M 4
00 "Special Effects".
( ) Push the three connectors from the harness G O i onto the pins on circuit
board E F 1.
( ) Push the connector from the harness G O 1 onto the pins of "Plug 2 " of the
circuit
board Z S 1 (treble end of stop board). Also see Fig. 45.
( ) Test all functions of the "Special Effects"; referring to AM 400. (The switch S
20 of A M 400 is located among the three switches at the treble end of the stop
board).
( ) Test the alternate audio path of the "Special Effects" via the Wersivoice while
depressing the tab "Spec. Eff.to Wersivoice ".
( ) The function of the switch "Speedshift Slow/ Fast can now be tested too.
Normaliv,the speed change from chorale to fast of the Wersivoice(Whirl mode) is
inertial (slow). When the tab "Speedshift Slow Fast" is depressed the speed
change is instantaneous. (The change from fast to choral remains sudden,
independent of the setting of the switch "Speedshift Slow/Fast".)
3.14 Testing of the Pedals
( ) Restore the controls of the organ as described at the beginning of paragraph
II.
