Button Names and Functions

 

6. D-Chorus

 

Thanks to dynamic band-splitting processing according to 

input signals, you can perform with a chorus effect with no 

loss in bass-range response. 

 

INTENSITY 

 

Knob

 

This adjusts the amount of chorus that’s applied. When you 

don’t want to use a chorus effect, set this to “Off” (the 

indicator goes dark). If you want to obtain a longer pre-delay 

effect, set this to a value of 7 or more. 

You can use a foot switch to toggle the chorus 

effect on and off. Note that this is not possible 

when the 

 

INTENSITY 

 

knob is off. 

 

7. Master

 

POWER INJECTION

This indicator only applies to the speaker output.

headphones.

memory A or memory B. 

 

PHONES

Before plugging in or unplugging headphones, be sure 

to adjust the
