T_LVL This sets the maximum output level of both triangle wave LFOs. Without a 'scope this
is difficult to set exactly but it doesn't really matter that much. Simply adjust the trimmer to its
middle position and you should find that the depth pot goes from nothing to all out freaky
vibrato.
If you do have a 'scope then set the triangle rate and depth pots to their maximum. Then
monitor the voltage on pin 1 of U11 and adjust T_LVL until you get a 10V peak to peak
signal.
S_FRQ This sets the frequency range of the sine wave LFOs. Insert an audio input into the
SE330. The A440 note is a good one to use again. Set the sine rate and sine depth pot to their
middle settings. Set the triangle wave depth pots to their minimum. Select the dimension mode
and turn the balance control to wet. Make sure the peak LED is not lit and listen to the left
output only. You should hear the pitch being modulated again but much more smoothly than
with the triangle wave LFO. Adjust S_FRQ so that you hear a ee-aw sound repeating once a
second.
If you have a 'scope, monitor the voltage at pin 1 of U22. Set the sine rate pot to its maximum
value and adjust T_FRQ until you get a 50Hz sine wave.
S_LVL This sets the maximum output level of both sine wave LFOs. Without a 'scope this is

If you do have a 'scope then set the triangle rate and depth pots to their maximum. Then
monitor the voltage on pin 1 of U31 and adjust S_LVL until you get a 10V peak to peak
signal.
