Delay (Short/Long) Mode
@ Delay Time
This knob controls the delay time. At
Deley Short, it continuously varies from
45 to 250ms, and at Delay Long from
200 to 1000ms.
© Feedback
This knob controls the number of delay
repeats. At its counterclockwise position,
a single delay is obtained.
® Effect Level
This knob sets the volume of the delay
sound. At its clockwise position, the
volume of the effect sound is approxi-
mately equal to the direct sound. At its
counterclockwise position, no delay
sound is produced.
Chorus Mode
@ Delay Time
This knob controls the delay time from
5.5 to 45ms continuosuly.
© Rate
This knob sets the rate of the modulation.
® Depth
This knob determines the depth of
the chorus effect. Clockwise rotation
deepens the effect.
Fianger Mode
© Manual
This knob changes the delay time from
0.7 to 4.5ms continuously
© Rate
This knob sets the rate of the modulation.
® Depth
This sets the width of the modulation at
the delay time set with @ Manual
