( ) Again, test the changeover of the sound to the other channel by clipping the
test lead to pin S 3 of the other preamp.
3.9 Testing of the Pedals
The drawbars and the fixed stops of the pedal section are to be tested in the
same way as the voices for the manuals. The corresponding control inputs at the
preamplifiers are:
S 6 for the drawbars (left and right)
S 5 for the fixed stops (left and right)
Clipping the test lead (-1 5 V D C) to any of these pins will activate the audio
inputs for the pedal drawbars or fixed stops respectively (and left or right
respectively).
3.10 Testing of the Frequency Vibrato
The fixed stop voices of the upper manual can be used to test the various modes
of the frequency vibrato.
We suppose that the tone generator was tuned after its assembly.
( )Turn on the switch "Delayed Vibrato".
( ) Depress one or more keys in the upper manual.
After a short delay a weak vibrato should appear. The delay is initiated everytime
a key is depressed after a pause in playing. The delay time can be adjusted by
means of trim pot P 3 on the tone generator board G 1. Our recommendation:
centre of rotation.
( ) Turn off "Delayed Vibrato" and turn on "Contin. Vibrato". The vibrato exists
immediately when a key is depressed.
