Precautions

1. Select a suitable location.
Keep the REV500 away from locations where it is likely to be exposed to high temperatures or humiditysuch as near radiators, stoves, etc. Also avoid locations which are subject to excessive dust accumulation or vibrations that could cause mechanical damage, and locations subject to strong electromagnetic fields such as those produced by broadcast equipment.
6. Clean with a soft dry cloth.
Never use solvents such as benzine or thinner to clean the REV500. Wipe the unit clean with a soft, dry cloth.
7. Always use the correct power supply.
Make sure that the power requirements listed on the rear panel of the REV500 match your local AC mains
2. Avoid physical shocks.
Strong physical shocks can damage the REV500. Handle the REV500 with care.
8. Have the back-up battery replaced regularly.
The REV500 has a long-life lithium battery that maintains the contents of the user memory even when the REV500 is off. Under normal use, the battery should last several years. However, Yamaha strongly recommends that you have the battery replaced by a qualified Yamaha service center every five years, to prevent the accidental loss of valuable data. Should the batterys 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 REV500s 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 REV500s 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.
3. Do not open the case or attempt repairs or modifications yourself.
This product contains no user-serviceable parts. Refer all maintenance and repair work to qualified Yamaha service personnel. Opening the case and/ or tampering with the internal circuitry voids the warranty.
4. Always turn the power off before making connections.
Always turn the power OFF before connecting or disconnecting cables. Failure to do so may damage the REV500 as well as other connected equipment.

5. Handle cables carefully.
Always grip the connector, not the cord itself, when plugging and unplugging cables (including the AC power cord).

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.
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 REV500s 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 REV500s utility functions. The HI-RATIO control sets the reverb time for the highfrequency 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.

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.

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.
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 REV500s utility functions.

6 STORE key

This key is used to store modified programs, and to execute MIDI bulk dumps.

7 AUDITION key

This key causes the REV500s internal tone generator to play a sound, allowing you to check the effect of the currently selected program. A utility function (see page 15) allows you to select one of two sounds for this key to play, and to set the REV500 to play this sound once or repeatedly when the AUDITION key is pressed.

8 UTILITY key and LED

This key lets you access the REV500s utility functions, which include MIDI settings and system-related functions. The LED above this key will light when a utility function is being used. See page 18 for a summary of the functions that can be accessed using this key.

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:
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 REV500s 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.
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.
Storing Data with MIDI Bulk Dumps
The REV500 is capable of transmitting its data as bulk dumps, for storage in a sequencer or other MIDI device. To use this function, first make sure that the REV500 is properly connected to the device that is to receive the data, and that the MIDI channels of the two devices match. Next, press UTILITY. If necessary, press the UTILITY key again until the MIDI BULK DUMP display appears:
Bulk dump type Program selection
Use the REV TIME control to select the type of bulk dump to be transmitted. The REV500 is capable of sending four types of bulk data:

MIDI Bulk Dumps

Dump Type ALL SYSTEM PGM PGM TABLE Data transmitted All data (system setup data, all user programs, and program table data) All system setup data Data for all programs, or data for a single specified program MIDI program table data
If you select PGM as the bulk dump type, you must select the program to be dumped. Use the PRE DELAY control to move the cursor to the program selection, and the REV TIME control to change the setting. If you select ALL PGM, the REV500 will send the data for all user programs as a single dump. You may also select a single user program and store it externally using an individual data dump. When you are satisfied with your selection, press the STORE key. The REV500 will execute the data dump. When you are finished transmitting data, press one of the PROGRAM keys to exit the utility mode.
