30: 3D FLANGER
Parameter Value Description
Filter Type OFF, LPF, HPF
Type of filter
OFF: no filter is used
LPF: cuts the frequency range
above the Cutoff Freq
HPF: cuts the frequency range
below the Cutoff Freq
Cutoff Freq 200–8000 Hz Basic frequency of the filter
Pre Delay 0.0–100.0 ms
Adjusts the delay time from when
the direct sound begins until the
flanger sound is heard.
Rate 0.05–10.00 Hz, note Frequency of modulation
Depth 0–127 Depth of modulation
Phase 0–180 deg Spatial spread of the sound
Feedback -98– +98%
Adjusts the proportion of the
flanger sound that is fed back into
the effect. Negative (-) settings will
invert the phase.
Output Mode SPEAKER, PHONES
Adjusts the method that will be
used to hear the sound that is out-
put to the OUTPUT jacks. The opti-
mal 3D effect will be achieved if
you select SPEAKER when using
speakers, or PHONES when using
headphones.
Low Gain -15– +15 dB Gain of the low range
High Gain -15– +15 dB Gain of the high range
Balance D100:0W–D0:100W
Volume balance between the di-
rect sound (D) and the flanger
sound (W)
Level 0–127 Output Level
