35. Delay Short 36. Delay Long 37. Echo Short 38. Echo Long The stereo delay and echo effect's offer independently variable left and right channel delays. 39. Stereo Flange This effect produces a pleasant "swirling" sound which can effectively thicken and add warmth to the sound of an instrument. The flanging effect is produced by varying the delay between two identical signals, thus producing a complex varying "comb filter" effect. Left Channel Delay (Lch DLY): 0.1 - 500 milliseconds in "delay" programs 0.1 - 250 milliseconds in "echo" programs Sets the time between the direct sound of the instrument and the first repeat heard from the left channel. Left Channel Feedback Gain (Lch F.B): -99% - +99% Sets the amount of the left-channel delay signal fed back to the input of the processor. The higher the feedback gain setting, the greater the number of delayed repeats produced. Right Channel Delay (Rch DLY): 0.1 - 500 milliseconds in "delay" programs 0.1 - 250 milliseconds in "echo" programs Sets the time between the direct sound of the instrument and the first repeat heard from the right channel. Right Channel Feedback Gain (Rch F.B): -99% - +99% Sets the amount of the right-channel delay signal fed back to the input of the processor. The higher the feedback gain setting, the greater the number of delayed repeats produced. Modulation Frequency (MOD. FRQ): 0.1Hz - 20 Hz Sets the speed of modulation, and hence the rate at which the effect varies. Modulation Depth (MOD. DEPTH): 0% - 100% Sets the amount of delay time variation, thus adjusting the depth of the effect. Modulation Delay (MOD. DLY): 0.1 - 100 millisec- I onds 1 This sets the basic delay time from the initial direct sound to the beginning of the flange effect. Feedback Gain (F.B. GAIN): 0% - 99% Determines the amount of flange signal which is fed back to the input of the processor for further modulation. More feedback increases the overall complexity, "strength" and decay time of the effect. 1dB) DSIIGRENCATL MOD. DEPTH L(R)/R(L) High Frequency Feedback (HIGH): x0.1 - x1.0 Controls feedback in the high-frequency range. The highfrequency feedback is reduced as the value of this parameter is decreased. I.N110D.
