INPUTS (CONT.)
EXPO FM
A/–10 volts. Allows linear frequency
modulation, where an increase or decrease
in control voltage respectively increases or
decreases the pitch of the oscillator in a manner
that has an exponential relationship to the
incoming voltage. That is to say that with each
volt of increase at the input the audio frequency
will double.
The input is DC coupled to allow the use
of voltage offsets, audio rate signals, and
everything in between.
This input is accompanied by an attenuator that
is located above the input jack. The incoming
signal is fully attenuated when the trimmer
is counterclockwise and passes through
unaffected when the trimmer is fully clockwise.
