turn the INPUT knob down. For traditional passive pickups it will help to turn the INPUT level
up.
o INPUT CALIBRATION FUNCTION: We have provided a unique Input Calibration
Function to assure that you are getting the best possible interaction between your
instrument and the C4. The Calibration process is as follows:
1. Turn the INPUT knob all the way down.
2. Continuously pluck your instrument at your average plucking velocity.
3. Slowly turn up the INPUT knob up until the center LED starts flashing red.
•
SENSITIVITY (Secondary Parameter). Adjusts how reactive the envelope filter is to the
incoming signal. If you like to play hard, but still want a smoother more relaxed envelope
filter, you should turn down the SENSITIVITY. For a sharper response to lighter playing, turn
up the SENSITIVITY.
MIX/VOL
A dual-function knob that adjust the wet/dry MIX and the overall output VOLUME.
•
MIX (Primary (Default) Parameter): The wet/dry MIX control adjusts the balance between
the natural dry tone of the instrument and affected wet signal. A 50/50 mix of wet dry signal
resides at roughly 12 o'clock on the knob. For a 100% wet signal turn the knob fully clockwise
- for a 100% dry signal turn the knob fully counter-clockwise.
•
VOLUME (Secondary Parameter): Adjusts overall output VOLUME of the pedal. Be aware of
that the overall VOLUME will likely vary depending on the signal density of the preset, so
make sure to A/B test the levels between your bypassed and engaged signals and adjust the
VOLUME accordingly.
CONTROL 1 & 2
The functions of these knobs vary depending on the selected synth engine. Use the Knob Assignment
section of the C4 Neuro Sound Editor to learn which parameter has been assigned to the CONTROL 1
and CONTROL 2 knobs.
Effect Toggle Switch
Use the C4's three-position toggle switch and two preset banks to easily access six different presets.
First Preset Bank (Indicated by the green center LED): by default the center toggle switch selects
between three presets (Circle, Triangle, Square) stored in the first bank of presets. Second Preset
Bank (Indicated by the red center LED): Pressing the ALT button on the topside of the pedal initiates
a blinking pattern from the small LED on the pedal's face, indicating that the second preset bank is
accessible with the toggle switch. Upon moving the toggle switch the center LED will turn red
indicating the current preset is drawn from the second bank. Follow the same process to switch back
to the green bank.
ALT Button (Alternate Function)
This is a small black button located on the topside of the pedal next to the CONTROL INPUT jack.
Pressing the ALT button temporarily puts the pedal into Alternate Control Mode (indicated by the
SA249
This flashing indicates that you have reached the optimum INPUT level.
Leave the knob where it is – the process is complete.
