The four PARAMETER EDIT controls on the REV500’s
front panel let you adjust the basic program parameters
quickly and easily. When you rotate one of these controls,
the program information in the LCD (shown above) will be
replaced by a graphic display indicating how the changes
you’ve made have affected the parameter in question. (The
display will return to normal a few moments after you stop
turning the control.)
Please note that you must save any changes you make before
you select another program or turn off the REV500; if you
fail to do so, your edited program will be lost. Refer to page
13 for instructions on how to store a program.
PRE DELAY
This control sets the length of the initial delay that will pass
before the reverb effect (including early reflections) begins.
You can set a delay from 0.0 ms to 200.0 ms (or 299.9 ms if
the ECHO➔REV effect type is selected).
REV TIME
This control sets the length of the main reverberation.
Possible reverb time values range from 0.3 to 99 seconds.
HI-RATIO
This control sets the reverb time for the high-frequency
component of the reverb effect as a proportion of the overall
reverb length (REV TIME parameter). Possible values are
0.1 to 1.0.
ER LEVEL
This control sets the level of the early reflections (i.e., the
initial reflections that precede the main reverberation). You
can set early reflection levels ranging from 0 to 100.
