ROW TWO
CARRIER INPUT
This is an input for external audio which replaces the VCO on the left of the
CARRIER MIX knob. Use this to process external signals via Spectravox’s
synthesis filter bank. The CARRIER INPUT Accepts line level signals.
AUDIO INPUT: -1.7V to +1.7V (Line Level)
VCA CV INPUT
This CV input to control the level of the Voltage-Controlled Amplifier (VCA). CV
signal here is multiplied with signal selected by VCA MODE switch (either ON or
EG), acting as a velocity control when in EG mode.
CV INPUT: 0V to +8V
ROW THREE
1V/OCT INPUT
This calibrated CV input controls the frequency of the VCO following the
1V/Oct standard. Summed with the setting of the VCO FREQ panel control.
CV INPUT: -5V to +5V
VCO OUTPUT
This is the audio output for the VCO.
AUDIO OUTPUT: -5V to +5V (10V peak to peak)
ROW FOUR
VCO PWM INPUT
This CV input to control the pulse width of the VCO (when VCO WAVE is set
to PULSE). A control voltage sweep from –5 volts to +5 volts covers the range
of the PULSE WIDTH potentiometer. (Set PULSE WIDTH to 12 o’clock for full
sweep via this input.)
CV INPUT: -5V to +5V
