In Phase mode the green LEDs to the of right lever 1 are active, but the panel
markings (0–300ms) do not represent the actual phase delay time values. In-
stead, the LEDs indicate the relative value between 0–15ms.
Predelay (Lever 4)
Lever 4 can be used as a common predelay to both phase delays. See
"Lever 4 Predelay" on page 243
Note:
Front/Rear
The Front/Rear Outputs switch is illuminated in Phase program mode. Chang-
ing the switch setting will yield a different comb filter phase. Due to the nature
of the effect in Phase mode, when the switch is in the Rear position and the
Phase time (lever 1) is at minimum and maximum values, the signal is only out-
put on one side (right-only at minimum, left-only at maximum). This behavior
is identical to the original hardware. See
for more information.

Chorus program mode creates an "ensemble" effect by simulating the impres-
Chorus
sion of multiple imprecisions added to the original signal. In EMT 250, this is
accomplished by routing the same signal to four delay processors, each hav-
ing short delay times that are continuously and randomly modulated.
While it was necessary to combine the various physical outputs for variations
of Chorus complexity, the EMT 250 plug-in is "pre-mixed" in four popular
combinations.
Note:
Chorus Mode (Lever 3)
Four subtle variations of the chorus effect are available (I, II, III, and IV). Lever
3 specifies the current variation.
