Controls

1 INPUT LEVEL control and meter

The INPUT LEVEL control sets the input level for both

the right and left input channels. It is accompanied by a

stereo LED meter that shows the levels of the signals

received by the REV500 after A/D conversion. Lighting

of the red CLIP LEDs thus indicates clipping of the

digital signal. You should adjust the control so that the

CLIP LEDs do not light.

2 PROGRAM keys

These keys let you choose the program that the REV500

will use to process the input sound.

The TYPE key selects the type of effect program to be

used: HALL, ROOM, PLATE, or SPECIAL. The current

program type selection is displayed in the upper left

corner of the LCD.

The PRESET/USER key selects between the PRESET

and USER program memory areas. The currently

selected memory area is displayed under the program

number in the LCD. It is possible to change the

parameters of a preset program, but the edited program

must be stored as a user program.

The NUMBER keys are used to select different programs

within the chosen program type and memory area. The

number and title of the currently selected program are

displayed in the top row of the LCD.

3 LCD

This LCD normally displays information about the

currently selected program. It also displays graphic

information about basic parameters being edited, as well

as a variety of other messages related to the REV500’s

utility functions.

4 PARAMETER EDIT controls

These controls let you edit the basic parameters of the

selected program.

The PRE DELAY control sets the amount of time that

will elapse before the onset of early reflections. It also

functions as a cursor control, which you can turn to

select the parameter or character to be modified when

using the REV500’s utility functions.

The REV TIME control sets the amount of time needed

for the reverberation to decay. It also functions as a data

entry control, which you can turn to change the values of

selected items when using the REV500’s utility

functions.

The HI-RATIO control sets the reverb time for the high-

frequency components of the reverb, as a proportion of

the overall reverb time set using the REV TIME control.

The ER LEVEL control sets the level of the early

reflection component of the reverb. It is also used, in

combination with the EFF LEVEL key, to adjust the

overall effect output level.

5 EFF LEVEL key and LED

This key lets you use the ER LEVEL control to set the

overall effect output level. When the LED above this key

is lit, the ER LEVEL control will adjust the effect level

instead of the early reflection level.

6 STORE key

This key is used to store modified programs, and to

execute MIDI bulk dumps.
