I/O and Panel Controls Explained
Signal IN (CH. 1,2,3,4): Direct Coupled input to associated circuit. Channels 2 and 3 are
normalized to a +5V reference for generation of voltage offsets.
Trigger IN (CH. 1,4): Gate or Pulse applied to this input will trigger the associated circuit
regardless of activity at the Signal IN. The result being a 0V to 10V voltage function, aka
Envelope, whose characteristics are defined by the Rise, Fall, Vari-Response and Scale/
Inversion parameters.
Activity/ Cycle Switch (CH. 1,4): This LED indicates activity within the associated circuit.
It also leads a double life as a push button which coaxes the circuit to self cycle, thus
generating a repeating voltage function, aka LFO.
Rise Panel Control (CH. 1,4): Sets the time it takes for the voltage function to ramp up.
CW rotation increases Rise Time.
Fall Panel Control (CH. 1,4): Sets the time it takes for the voltage function to ramp down.
CW rotation increases Fall Time.
Rise Control IN (CH. 1,4): Bi-Polar Linear control signal input for Rise parameter.
Positive Control signals increase Rise Time. Negative control signals decrease Rise Time.
Fall Control IN (CH. 1,4): Bi-Polar Linear control signal input for Fall parameter. Positive
control signals increase Fall Time. Negative control signals decrease Fall Time.
Both Control IN (CH. 1,4): Bi-Polar Exponential control signal input for entire Function.
Positive control signals decrease Total Time. Negative control signals increase Total
Time.
Scaling/ Inversion Panel Control (CH. 1,2,3,4): provides for scaling, attenuation and
inversion of the signal applied to the associated channel. When this control is set to
NOON, there will be zero signal. At full CW there will be maximum signal. At full CCW
there will be maximum Inverted signal. Channels 2 and 3 also offer a small amount of
Gain.
Vari-Response Panel Control (CH. 1,4): sets the response curve of the voltage function
for the associated circuit. Response is continuously variable from Logarithmic through
Linear to Exponential.
Signal OUT (CH. 1,2,3,4): the applied signal as processed by the associated MATHS
channel. All four of these sockets are normalized to the SUM and OR busses. Inserting a
patch cable will remove the associated signal from the SUM and OR busses. All of these
outputs are buffered and capable of accurately driving a 4 way multiple.
Signal OUT Multiple (CH. 1,4): buffered multiple of the Signal OUT for the associated
circuit. This socket is NOT normalized to the SUM and OR busses and therefore, inserting
a patch cable to this socket will not remove the associated signal from the Sum and OR
busses.
OR Bus OUT: Result of the Analog Logic OR function.
SUM Bus OUT: Sum of the applied voltages.
