Each unique parameter in the plug-in retains a distinct value, but only the pa-
rameters that are active in the current program mode are visible in the graph-
ical user interface. All parameters are always visible in Controls View (see
Chapter 7 of the UAD System Manual), even when they are not active in the
current program mode.
Important:
program mode are not saved in sessions or presets. The unsaved parameters
are marked with an asterisk in
When switching between program modes that have different parameters
mapped to the same control, parameter values are retained within each mode
(controls jump back to the prior value that was set in each respective mode).
In all program modes, lever 4 controls the predelay (the initial delay before
Lever 4 Predelay
other processing occurs) of both channels (left and right). Predelay times of
0ms, 20ms, 40ms, and 60ms are available in 4 steps. The green LEDs on the
right side of lever 4 display the current predelay value.
Mono/Stereo The EMT 250 hardware unit has one (mono) input. For accurate emulation
Operation
when the plug-in is used in a stereo-in/stereo-out configuration, stereo signals
at the plug-in input are summed to mono before processing; the dry signal is
passed in stereo.
Four channels of processed audio, selectable with the Front/Rear Outputs
switch, are generated from this mono input in all modes (with the exception of
Echo, which has mono output only).
Front/Rear The EMT 250 hardware unit has four discrete outputs. Two outputs were de-
Outputs
signed to be used as the main stereo left/right outputs, or the "front" left/right
outs in quadraphonic applications. The other two outputs were used for the
"rear" left/right signals in quad (or other creative applications). The UAD
EMT 250 fully models the individual sonics of all four outputs.
The name of the "Front/Rear Outputs" switch is derived from the original
hardware design. This control (which is unique to the plug-in) enables access
to the processed quadraphonic signal in pairs, at either the front L/R or rear
L/R outputs. When a different sound is available at the front and rear outputs,
the yellow "LED ring" around the control is illuminated. For program modes
that do not offer quadraphonic processing (e.g., Delay), the switch is re-pur-
posed to sum the processed outputs to mono. In Echo mode, it functions as an
input mute.
