Positions "I" and "II" are of a simpler nature, while "III" and "IV" are more
complex. Position "I" duplicates the Left Front and Right Front outputs of the
hardware. "II" duplicates Left Rear and Right Rear outputs of the hardware.
"III" combines both the Left Front and Left Rear on the left side, and Right Front
and Right Rear on the right. "IV" combines Left Front, Left Rear and Right Rear
on the left side, and Left Rear, Right Front and a phase inverted Right Rear on
the right. "IV" imparts a pseudo-quadraphonic sound.
Predelay (Lever 4)
Lever 4 is can be used as a common predelay to all four delays. See
"Lever 4 Predelay" on page 243
Front/Rear
In Chorus mode, the Front/Rear Outputs switch is not illuminated (the sound
is identical in both pairs of outputs). When moved to the Rear position, the
plug-in output is summed to mono. See
for more information.
Echo program mode produces a single monophonic delay effect, with feed-
Echo
back and adjustable delay time. Up to 375ms of delay is available.
The feedback (recirculation) circuit is always active in Echo mode. The feed-
back signal path is attenuated by approximately 10% per loop circulation,
and includes an adjustable high frequency attenuator for damping.
Note:
ting the coarse, fine, and predelay times to their respective maximum values.
Coarse Echo Time (Lever 1)
Lever 1 controls the coarse delay time. The coarse delay time range is 0 to
300ms, selectable via 16 steps.
The green LEDs on right side of lever 1 display the current value; the red LEDs
on the left side of lever 1 are inactive.
Fine Echo Time (Lever 2)
Lever 2 controls the fine delay time. Fine delay times of 0ms, 5ms, 10ms, and
15ms are available. The green LEDs on right side of lever 2 display the cur-
rent value; the red LEDs on the left side of lever 2 are inactive.
