Stereo Delay Chorus
Delay and Chorus can be combined to create spaciousness.

Parameter (full name) Setting Function
Delay:Adds a delayed sound to the direct sound, adding depth to the sound or creating special effects.
Sw (Switch) On, Off Turns the delay on or off.
Time (Delay Time) 0–500 ms Sets the time from direct sound until when the delay sound is heard. *1
Shift (Delay Shift) L500–0–R500 ms Sets the delay time difference between the right and left delay sounds.
Lch FeedbackLvl (Lch Feedback Level) -100–100 Sets the amount of the left-side delay should be returned to the left delay input.
Rch FeedbackLvl (Rch Feedback Level) -100–100 Sets the amount of the right-side delay should be returned to the right delay input.
Lch CrossFeedbackLvl (Lch Cross-Feedback Level) -100–100 Sets the amount of the left-side delay should be returned to the right delay input.
Rch CrossFeedbackLvl (Rch Cross-Feedback Level) -100–100 Sets the amount of the right-side delay should be returned to the left delay input.
FX Lvl (Effect Level) -100–100 Sets the volume of the delay sound.
DirLvl (Direct Level) -100–100 Sets the volume of the direct sound.
Chorus: Adds spaciousness and depth to the sound.
Sw (Switch) On, Off Turns the chorus on or off.
Rate (Rate) 0.1–10.0 kHz Sets the rate of modulation.
Depth (Depth) 0–100 Sets the depth of modulation.
PreDLY (Pre-Delay) 0–50 ms Sets the time delay from when the direct sound begins until the processed sound is heard.
Lch FeedbackLvl (Lch Feedback Level) -100–100 Sets the amount of the left-side chorus sound should be returned to the left chorus input.
Rch FeedbackLvl (Rch Feedback Level) -100–100 Sets the amount of the right-side chorus sound should be returned to the right chorus input.
Lch CrossFeedbackLvl (Lch Cross-Feedback Level) -100–100 Sets the amount of the left-side chorus sound should be returned to the right chorus input.
Rch CrossFeedbackLvl (Rch Cross-Feedback Level) -100–100 Sets the amount of the right-side chorus sound should be returned to the left chorus input.
FX Lvl (Effect Level) -100–100 Sets the volume of the chorus sound.
DirLvl (Direct Level) -100–100 Sets the volume of the direct sound.
EQ (Equalizer)
Sw (Switch) On, Off Turns the equalizer on or off.
Low Gain (Low Gain) -12– +12 dB Sets the boost/cut amount in the low frequency band.
Low Freq (Low Frequency) 20 - 2000 Hz Sets the center frequency in the low frequency band.
Low Q 0.3–10.0 Sets the width of the area around the low frequency that will be affected by the gain settings. *2
Low Type Shlv, Peak Sets the type of the low frequency band equalizer (Shlving type or peaking type).
Mid Gain (Middle Gain) -12– +12 dB Sets the boost/cut amount in the middle frequency band.
Mid Freq (Middle Frequency) 200–8000 Hz Sets the center frequency in the middle frequency band.
Mid Q (Middle Q) 0.3–10.0 Sets the width of the area around the middle frequency that will be affected by the gain settings.
High Gain -12– +12 dB Sets the boost/cut amount in the High frequency band.
High Freq (High Frequency) 1.4–20.0 kHz Sets the center frequency in the High frequency band.
High Q 0.3–10.0
Sets the width of the area around the High frequency that will be affected by the gain settings. *2
Hi Type (High Type) Shlv, Peak Sets the type of the High frequency band equalizer (Shlving type or peaking type).
Level (Output Level) 0–100 Sets the volume after passing through the equalizer.
*1: The sum of the Delay Time (Time) value and the Delay Shift (Shift) value should not exceed the setting range of Delay Time. For example, if the delay time is
set to 300 ms, the setting range of Delay Shift is L200 to R200 ms.
*2: If Lo Type (Low Type) or Hi Type (High Type) is set to “Shlv (Shlving Type),” the setting for Lo Q or High Q is invalid.

How feedback works for Delay and Chorus
Feedback is the feature to return the effect sound to its input. The amount of feedback is set with FBLevel (Feedback Level).
Cross-Feedback is the feature to return the effect sound from the right input to the left input and the effect send from the left
input to the right. The amount of cross-feedback is set with Cross-Feedback Level (CrossFB Level).
The greater this value becomes, the more times the delay sound is repeated. Setting this level to a negative value inverts the
phase.
For feedback of chorus, the greater the value becomes, the more spaciousness and thickness is added to the sound. Setting
this level to a negative value inverts the phase.
* Excessively great values may cause oscillation, leading to abnormal noise.
