Getting Started

Main Features

The DPS-V55M is a four channels multi-effect processor.

Four channel construction

The DPS-V55M is outfitted with four inputs (and outputs) and can route the input signals in a variety of different ways depending on the chosen effect algorithms and program structures.

Flexible effect algorithms and program structures

The DPS-V55M incorporates a total of 45 different effect algorithms divided into three different types: 4ch, 2ch (stereo), and Mono-Pair. Each effect contains several adjustable parameters and can be easily modified. In addition 2ch and/or Mono-Pair effects can be used in combination within a program, and the program structure can be switched between serial and parallel, allowing you to take full advantage of the four channel construction.

User-friendly operating environment

A primary concern when creating the DPS-V55M, was to provide an intuitive operating system for creative sound control. All effect parameters can be accessed directly using the EDIT PARAMETER buttons.

Large memory banks

In addition to the 200 different preset programs (numbers 001~200) created by musicians and engineers from around the world (preset memory), there is also room for you to store up to 200 of your own original programs in the user memory (numbers 201~400). We've also included a search function so you can recall the programs you need without having to remember their program numbers.

Search function

The search function lets you locate programs you want by specifying the type of effects they contain. (See page 12.)

TAP function

The TAP function lets you adjust certain parameters or trigger certain effects simply by tapping on the ENTER (TAP) button. (See page 15.)

MIDI compatibility

The MIDI interface lets you conduct program change and data save operations. (See page 17.)

How to Use This Manual

Understanding Effect Algorithms and Program Structures

Effect algorithms

This unit contains three types of effect algorithms: 4ch, 2ch, and Mono-Pair.

The 4ch effects (algorithms # 01~09) are designed to handle four channels simultaneously. These are also the highest quality effects. Consequently, programs containing these effects can not contain any other effects.

2ch effects (algorithms # 10~36) and Mono-Pair effects (algorithms # 37~45), on the other hand, are designed to handle two channels simultaneously and can be used in various combinations within a program. Each program can contain two 2ch effects, two Mono-pair effects, or one 2ch effect and one Mono-Pair effect.

The 2ch effects are "traditional" stereo effects. Mono-Pair effects are combinations of two parallel mono effects (one for each channel).

Program structures

Each program can contain up two effects (FxA and FxB) depending on the type of effect selected.

If a 2ch or Mono-Pair effects are selected, the program contains two effects (one, or both can be turned off if necessary). When a program contains two effects, the way the unit routes the signals through the effects is controlled by the program structure. There are two possible program structures: parallel (/) and serial () .

Parallel (/) program

FxA and FxB are completely independent.

Serial () program

The sound from FxA is fed into FxB for further processing before being output.

If a 4ch effect is selected, the program contains only one effect (the other effect is automatically disabled).

Example of program containing a 4ch effect

FxA only

Hooking Up

• Before connecting this unit to another device, be sure to unplug the AC power cord from the power outlet.
• Turn off the power switch on this unit and all components to be connected, such as keyboards and active speakers (speakers with built in amplifiers).
• After all the connections, double check that the connections are correct before plugging the AC power cord back into the power outlet.
• If the connected components output large signals that cause distortion, adjust the INPUT LEVEL knobs on this unit to lower the input level, or lower the output level of the connected component.

Example 1: Hooking up to instruments

Example 2: Hooking up a mixer (Mono send, Stereo return)

Example 3: Hooking up to a mixer (cutting the direct sound) (Stereo send, Stereo Return)

When using the processor in a send-return loop

• When using effect that have an effect level parameter, we recommend setting the direct sound to "0" so that only the sound of the effect will be output.
• We also recommend setting the BYPASS function to "Muting" (as shown on page 18).

Basic Operations

Choosing a Program

The processor comes with 200 different preset programs (numbers 001 200 ) as well as room for 200 user programs for storing the programs you create (numbers 201 400 ). Use the following procedure to choose the program you desire.

1 Press ① to turn on the power.

After a few seconds, the play mode screen appears.

001 Super Reverb F× A:11 / F× B:12

2 Turn INPUT LEVEL (1~4) to adjust the input levels.

If an input level indicator lights red (clip), the input level for that channel is set too high. Be sure to set the input level correctly since it has a direct relationship to the quality of the effects (see page 6 for details).

3 Turn the rotary encoder to select a program (001~400).

The program numbers (and corresponding names) appear in the display as you turn the jog dial.

Before you turn on the connected components Be sure to turn the volume level down to avoid an unexpected output of massive volume.

You can also search programs by effect type. See page 12 for details.

4 Press EXIT to return to play mode.

Using the TAP function

This function lets you change the value of certain time related parameters or trigger an effect by tapping on the ENTER (TAP) button.

The parameter which responds to the TAP function is different for each effect, and not all effect have compatible parameters. However, many time related parameters (such as Delay Time) or parameters activated by a trigger (such as Key Trigger) are designed to work with the TAP function. (Refer to the separate Effect Parameter Guide for specific information.)

The TAP function works the same in either play mode or edit mode, but not can not be used when any other modes (such as SYSTEM or SAVE) are active.

To use TAP with time related parameters ("Time" below)

Select a program containing a compatible effect, then tap ENTER (TAP) repeatedly to enter the desired tempo.

The effector's tap editor measures the timing of the last two taps an sets the corresponding parameter accordingly.

You can also change the ratio between your taps and the actual parameter value (see page 18 for details).

To use TAP as a trigger ("Trigger" below)

Press ENTER (TAP) at the point where you want to activate the effect.
