prevent the accidental loss of valuable data.
• Should the battery’s voltage fall below a certain level, the
message “LOW BATTERY” will appear in the LCD when
you turn the REV500 on. If this happens, it means that
contents of your REV500’s user memory have been lost.
Have the backup battery replaced immediately.
• Prompt and regular replacement of the back-up battery
is necessary to prevent the loss of important data. In
addition, if possible, you should use the MIDI bulk dump
function (see page 17) regularly to store backup copies
of your REV500’s data in a MIDI sequencer other MIDI
device. This will allow you to recover your data should
the back-up battery run down sooner than you think.

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.

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.

Changing the Effect Level
You can also use the ER LEVEL control to adjust the effect
level, that is, the level of the total effect output. To do so,
press the EFF LEVEL key before turning the ER LEVEL
control. The LED above this key will light, and (as with the
other basic parameters) the program information in the LCD
will be replaced by a graphic display. You can set a level
from 0 to 100.
Realtime Parameter Control
The REV500 also lets you dynamically change the
aforementioned basic parameters in realtime, using MIDI
Control Change messages. The controller numbers for these
parameters are shown in the table below.

Editing Internal Parameters
In addition to the basic parameters described previously, the
REV500’s programs have a variety of internal parameters
that can also be edited.
To edit a program’s internal parameters, press the UTILITY
key. If necessary, press the UTILITY key again until the
INT. PARAMETER display appears:
Cursor
Parameter name
Value
Use the PRE DELAY control to move the cursor from the
parameter name to the parameter value and vice-versa. Use
the REV TIME control to select the parameter you wish to
edit, and to adjust the value assigned to the parameter you
select.
Please note that the parameters available for editing will vary
with the effect type of the program you have selected. You
can identify the effect type of a program by checking the
upper right corner of the LCD.
Effect type
Refer to the next section for a list of the internal parameters
for each effect type.
When you are done editing internal parameters, press one of
the PROGRAM keys to exit the utility mode. Remember that
(as with other program parameters) you must save the
program you have just edited before selecting another
program or turning the REV500 off, or your changes will be
lost. Refer to page 13 for instructions on how to store a
program.
Changing a Program’s Title
You can assign a program you have edited a new title, for
easy recognition.
To edit a program’s title, begin by pressing the UTILITY
key. The LED above this key will light, and one of the
REV500’s utility function displays will appear in the LCD.
If necessary, press the UTILITY key again until the TITLE
EDIT display appears:
Cursor
Use the PRE DELAY control to select a character you wish
to change, and the REV TIME control to change that
character. Repeat this process until the title appears as you
wish it to read.
When you are done editing the title, press one of the
PROGRAM keys to exit the utility mode. Remember that (as
with other program parameters) you must save the program
you have just edited before selecting another program or
turning the REV500 off, or your new title will be lost. Refer
to page 13 for instructions on how to store a program.

System Functions
Selecting an Input Mode
If you will be using the REV500 to process monophonic
input (from the left input connector), you must use the
INPUT SELECT function to inform it of this fact.
To change the input mode, first press the UTILITY key. If
necessary, press the UTILITY key again until the INPUT
SELECT display appears:
Stereo input
Mono input
Use the REV TIME control to switch between the STEREO
and L-MONO input settings. When you have made your
setting, press one of the PROGRAM keys to exit the utility
mode.
Selecting an Output Mode
You can set the REV500 to output the processed effect
signal only, or a mixture of the both direct output and the
processed signal. (If you elect to add the direct signal, the
balance between the direct and effect output signals will be
determined by the EFF LEVEL setting.)
To change the output mode, first press the UTILITY key. If
necessary, press the UTILITY key again until the OUTPUT
MODE display appears:
Effect output only
Effect plus direct output
Use the REV TIME control to switch between the EFFECT
ONLY and ADD DIRECT output mode settings. When you
have made your setting, press one of the PROGRAM keys to
exit the utility mode.
Setting the Footswitch Function
You can use an FC5 footswitch with your REV500, for
hands-free control of one of two functions frequently
required during live performances. You can use the
footswitch either to mute the REV500’s effect output, or to
advance the current program selection.
You can select which of these two roles the footswitch will
perform using a utility function. To access this function,
press the UTILITY key. The LED above this key will light,
and one of the REV500’s utility function displays will
appear in the LCD. If necessary, press the UTILITY key
again until the FOOT SWITCH display appears:
Footswitch mutes effect
Footswitch
changes program
Program
change range
Use the REV TIME control to switch between the EFF
MUTE and PGM SEL functions. If you select the former, the
REV500’s effect output will be suppressed when you
depress the footswitch. Depress the footswitch again to
release the effect mute.
If you select the latter function, depressing the footswitch
will cause the current program selection to advance in the
order specified by the MIDI program change map (see page
16). This function also lets you adjust the range of MIDI
program change numbers that the footswitch can select. Use
the PRE DELAY control to move the cursor from PGM SEL
to the range setting, then use the REV TIME control to
adjust the upper value of this setting (which may be
anywhere from 1 to 128). The footswitch will advance the
current program selection until it reaches the program
change number you have set. Depressing the footswitch
again will return the program change number to 1.
When you have made your settings, press one of the
PROGRAM keys to exit the utility mode.
15
Adjusting the Audition Function
The REV500 lets you customize the audition function to suit
your needs. You can select one of two tones: either a snare
drum or a rim shot. You can also specify whether pressing
the AUDITION key will play the selected tone once, or start
it playing repeatedly. You can also turn the function off, to
prevent the REV500 from producing unwanted sounds if this
key is pressed accidentally.
To adjust the audition function, first press the UTILITY key.
If necessary, press the UTILITY key again until the DEMO
TONE TRIG display appears:
Tone selection Trigger mode
Cursor
Use the PRE DELAY control to move the cursor from the
tone selection parameter to the trigger mode parameter, and
vice-versa. Use the REV TIME control to select the desired
tone (SNARE or RIM), or the desired trigger mode (OFF,
ONCE, or SEQ).
When you are satisfied with your settings, press one of the
PROGRAM keys to exit the utility mode.
Changing the Initial Title Display
This utility function lets you personalize your REV500 by
entering a short message that will be displayed briefly when
you turn on the power. This message can consist of two lines
of up to 14 characters each.
To edit this initial title display, begin by pressing the
UTILITY key. If necessary, press the UTILITY key again
until the INI TITLE 1/2 display appears:
Cursor
Cursor
This display is used to edit the first line of the initial title.
Use the PRE DELAY control to select a character you wish
to change, and the REV TIME control to change that
character. Repeat this process until the line appears as you
wish it to read.
When you are satisfied with this line of your startup
message, press the UTILITY key a second time to display
the INI TITLE 2/2 display. Repeat the process to edit the
second line.
When you are done editing the initial title, press one of the
PROGRAM keys to exit the utility mode.
Initializing the REV500’s User
Memory
At some point you may wish to clear the edited programs out
of your REV500’s user memory and restore it to factory
condition. The method for doing this is as follows:
Hold the STORE key down as you turn the POWER switch
on. The REV500 will instruct you to press the STORE key a
second time to initialize its memory. Press the STORE key
to go ahead with the initialization, or any other key if you
decide you don’t want to.
Please be aware that this procedure will initialize any system
settings and MIDI settings (such as the MIDI program
change map) as well as the contents of the user memory area.

Using MIDI Functions
Selecting a MIDI Channel
You can change the MIDI channel that the REV500 uses to
transmit and receive data. First, press the UTILITY key. If
necessary, press the UTILITY key again until the MIDI
CHANNEL display appears:
MIDI channel setting
Use the REV TIME control to select the desired MIDI
channel. You can set the REV500 to use any of channels 1
through 16, or select OMNI for all channels. You can also
select OFF to disable MIDI communication.
When you have made your setting, press one of the
PROGRAM keys to exit the utility mode.
Using the MIDI OUT Function
This function determines whether MIDI channel messages
received at the MIDI IN terminal will be echoed through to
the MIDI OUT terminal. You should turn this function on
when you want to connect two or more REV500s in a “daisy
chain” so they can be controlled by a single master device
such as a sequencer or keyboard.
Begin by pressing the UTILITY key. If necessary, press the
UTILITY key again until the MIDI OUT display appears:
MIDI message echo setting
Use the REV TIME control to select between the ECHO
BACK ON and ECHO BACK OFF settings. If you choose
ECHO BACK ON, the MIDI channel messages received at
the MIDI IN terminal will be echoed through to the MIDI
OUT terminal. (Other messages received at the MIDI IN
terminal will not be echoed.)
When you have made your setting, press one of the
PROGRAM keys to exit the utility mode.
Editing the MIDI Program Change
Map
The REV500 has a MIDI program change map that assigns
REV500 programs to MIDI program change numbers. This
feature facilitates remote selection of REV500 programs
(which are stored in eight banks numbered 1 through 25)
using MIDI Program Change messages (which can specify
program numbers from 1 through 128).
To edit the MIDI program change map, first press the
UTILITY key. If necessary, press the UTILITY key again
until the MIDI PGM TABLE display appears:
REV500 program selection
MIDI program change
number and cursor
Use the PRE DELAY control to move the cursor to the MIDI
program change number, and the REV TIME control select a
program change number whose program assignment you
want to change. Then move the cursor back to the REV500
program selection, and use the REV control again to select
the program that you want the REV500 to use when it
receives the selected program change number.
Repeat this process to change as many MIDI program
change assignments as you like. When you are done editing
the program change map, press one of the PROGRAM keys
to exit the utility mode.
If you are using a Yamaha FC5 footswitch with the
REV500’s footswitch utility function set to PGM INC/DEC,
depressing the footswitch will select REV500 programs
sequentially in the order specified by this MIDI program
change map.
