Editing Programs Editing Basic Parameters Early Reflections REVERB REV TIME This control sets the length of the main reverberation. Possible reverb time values range from 0.3 to 99 seconds. ER LEVEL PRE E/R DLY DELAY REV TIME Reverb Time x Time LO-RATIO 1.0 HI-RATIO Frequency 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). 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. 8
