filter, you should turn down the SENSITIVITY. For a sharper response to lighter playing, turn
up the SENSITIVITY.
DEPTH/MIX Knob
A dual function knob that adjusts the modulation DEPTH of the filter and the wet/dry MIX.
DEPTH (the Primary (Default) Parameter): Adjusts the breadth of the filter modulation.
Increasing this knob widens the movement of the filter over the frequency spectrum making
the filter effect more prominent.
MIX (the Alternate Parameter): 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.
FREQ/RES Knob
A dual function knob that adjusts the FREQUENCY starting point of the filter modulation as well as
the RESONANCE of the filter.
FREQ (Primary): Adjusts the frequency starting point of the filter modulation. Moving this
knob to the left will move the filter over lower frequencies and create a darker sound,
moving the knob to the right places the filter over higher frequencies and create a brighter
sound.
RES (Alternate): Adjusts the resonance (also referred to as “Q”) of the filter. Increasing the
Resonance knob essentially boosts the height (or “level”) of the frequency peaks and
deepens the notches in the frequency cuts.
SPEED/VOL Knob
A dual function knob that adjusts the SPEED of the envelope attack and decay, as well as the overall
VOLUME level.
SPEED (Primary): Adjusts the SPEED of the Attack and/or Decay of the envelope follower. In
most cases turn this knob to the right for a quick, snappy envelope filter sound and to the left
for a slower, more sweeping sound. When using and LFO (available in the Neuro Editor) the
SPEED knob adjusts the speed of the filter’s LFO modulation.
VOLUME (Alternate) Adjusts the master VOLUME/Output of the pedal. Unity gain usually
resides at around the 12 o’clock knob position.
Effect Toggle Switch
Use the Spectrum’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 (TRON, DUMPLING, THRUST) 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.
