This section is intended to familiarize you with the basic operation steps of the RFX-2000.

Power UP

1. Verify that the AC adapter, sound source, and playback system are correctly connected to the RFX-2000.

The INPUT control and OUTPUT control of the RFX2000 as well as the volume control of the playback system should be set to minimum.

2. Turn on the system in the following order: sound source RFX-2000 playback system.

3. While playing the sound source, turn up the

INPUT control of the RFX-2000 to adjust the input level.

To minimize noise and distortion, the INPUT control should be set as high as possible without causing the CLIP LED to light.

4. Adjust the OUTPUT control and the volume control of the playback equipment to obtain a suitable playback volume.

Selecting a Patch

The memory of the RFX-2000 contains 100 stored patches. The display shows the number of the currently selected patch (01, 02,...99, 00). This condition is called the play mode.

To switch patches, proceed as described below. We suggest that you simply try out various patches to see what kind of sound the unit can produce.

1. Use the VALUE UP/DOWN keys to select the number of the desired patch.

The VALUE UP key switches to higher patch numbers and the VALUE DOWN key to lower patch numbers.

2. While playing the instrument or producing sound from the sound source, switch patches to check out the resulting sound.

Bypassing the Effects

You can temporarily turn effect processing off, so that only the original sound is output. This is useful to quickly check the change brought about by an effect.

1. To set the RFX-2000 to the bypass mode, press the BYPASS key while the unit is in play mode.

BYPASS

BYPASS

The BYPASS indicator lights up.

The RFX-2000 has two different bypass states, depending on the effect in the currently selected patch. (For information on which effects use which bypass type, please refer to pages 14 - 23.)

•WET MUTE

In this condition, only the effect sound is muted and the original sound is output. The level of the original sound output depends on the MIX control position. Therefore there may be a drop in volume or the sound may be entirely cut off.

•DRY THRU

The original sound is output without any processing. The setting of the MIX control has no effect on the volume level.

2.To cancel the bypass mode and return the RFX-2000 to the normal state, press the BYPASS key once more.

6 ZOOM RFX-2000

A patch called up from memory can be edited using the front-panel controls. You can for example select different effects and adjust effect intensity and other parameters.

If any parameter is changed from the stored condition, the new parameter value is shown on the display for about 2 seconds, and the EDITED mark (.) at the right edge of the display

appears. This indicates that the current patch has been edited. Because the LED of the control knob that was used to adjust the value also lights, it is easy to see which parameter has been edited.

Note:

When the effect is changed, the LEDs of all control knobs except the MIX control light up.

Changing the Value of an Effect Parameter

Each effect of the RFX-2000 consists of certain effect parameters which determine the intensity and tone character of the effect. Effect parameters can be adjusted with the following edit controls.

Storing an Edited Patch

If an edited patch is not stored in memory, the edited contents will be lost when another patch is selected. When wishing to keep the edited patch, store it in memory as follows.

2. To return to editing, press the COMPARE key once more (or press the CANCEL key).

•If desired, you can check the original value of each parameter by pressing the PARM CHECK key while the unit is in the compare mode.

•Moving any of the controls in compare mode has no effect.

Setting Parameters With the Tap Key (Tap Input)

The RFX-2000 allows input of time-based parameters by tapping the TAP key at the desired intervals. For example, the flanger modulation speed or delay time can be easily matched to the tempo of a song in this way.

1. Select a patch for which tap input is possible.

Whether tap input is possible or not depends on the effect selected for that patch (see pages 14 - 23). When a patch for which tap input is possible is selected, the TAP LED flashes.

TAP

2. Hit the TAP key several times in the desired interval.

The delay time or rate is set according to the tap interval and the tap beat parameter set for the respective patch (see page 12).

3. If desired, store the patch.

The parameter changed by tap input will revert to the original setting when the patch is switched. If wishing to retain the change, you should therefore store the patch.

•The parameter which can be set by tap input is preset (see pages 14 - 23).

•The maximum interval that can be measured by the tap input function is 2 seconds.

•If the tap input interval is outside the setting range for that parameter, it will be corrected to an acceptable value.

•If a parameter was set by tap input and is then changed by moving the control knob for that parameter, the control knob setting will override the tap input.
