AM 079 (Part) 

The Wersivoece switches on the stop board are "off". In that case the vibrato 
(Whirl) is at its normal intensity and at the fast speed. 

11 

(  ) Turn on a few fixed stops in the lower manual. 
 
(  ) Pull a few drawbars of the lower manual. 
 
(  ) Push the connector for plug 4 on the right preamplifier onto the pins. 
 
(  ) Set the volume control " L/Man" about mid-way. 
 
(  ) Hold a chord on the lower manual and alternate the positions of the tongue 
tab " Drawbars/Fixed Stops" of the lower manual. You should hear the drawbar 
sound with the switch in the "up" position and the fixed stops in the "down" 
position. 
 
(  ) Turn on all fixed stops of the lower manual. Pull XI 
out all drawbars of the lower manual. 
 
(  ) Hold down a key or chord on the lower manual. Alternate between drawbars 
and fixed stops and balance the volume of the fixed stops with the one from the 
drawbars by means of trim pot P1 on GP 2(L/Man). 
 
(  ) Repeat the entire procedure from the beginning of this paragraph XI for the 
upper manual and for the pedals respectively. 
 

3.12 Testing of the Wersivoice 

 
(  ) Push the 3 connectors from the harness G O 3 onto the pins o n the 
Wersivoice circuit board WV 7. 
 
(  ) Turn off any vibrato (switches " Reverb/Vibrato, etc."). 
 
(  ) Select some bright fixed stops in both manuals and pull the drawbars for a 
matching bright sound. 
 
(  ) The switches "Fixed Stops to Wersivoice" (in both manuals), when pushed 
down, assign the respective sounds to the Wersivoice. The Wersivoice imposes 
a rather complex vibrato on the sound such that it seems to emerge from rotating 
speakers or baffles. 
 

 

3.13 Testing of the Channel Selectors 

 
(  ) Push the connector for plug 4 onto the pins of the left preamplifier. 
 
(  ) While playing on the upper manual, activate the channel selector switch " 
U/Man Left/Right". The sound should switch back and forth between the amplifier 
channels. 
 
(  ) Repeat the procedure for the lower manual. 
 
(  ) Assign the drawbars of the upper manual to the Wersivoice and play on the 
upper manual. Activate the switch "Wersivoice Left/Right". The sound should 
alternate between channels. 
 

3.14 Testing of the Swell Pedal and Reverb 

 
(  ) Push the connector of the harness G O 3 onto the pins of "Plug 1 " of both 
preamplifiers (board VV 1). Refer to Fig. 40 for proper orientation of the 
connectors. 
 
(  )Set all channel selectors to "Right". 
 
(  ) 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" on the 
right channel V V 1 for minimum volume. 
 
(  ) Set all channel selectors to "Left". 
 
(  ) Repeat the -Null" adjustment for the left channel. 
 
(  ) Turn on the switch " Reverb I" and push Be swell pedal down. Hit a chord 
briefly and observe the reverb. 
 
(  ) Turn off " Reverb I" and turn on " Reverb II". The reverb should be 
lengthened.
