Effect Processor. Before operating the unit,
please read this manual thoroughly and
retain it for future reference.

Main Features
The DPS-V55 is a four channels multi–effect processor.
Four channel construction
The DPS-V55 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-V55 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–V55, 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 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
These operating instructions describe setup and operating
procedures for the DPS-V55 multi–effect processor.
Before using this unit we do recommend taking a glance at the
“Functional Hierarchy” chart on page 5 and reading
“Understanding Effect Algorithms and Program Structures” on
page 8 to familiarize yourself with the unit.
“Hooking Up” shows you how to make different kinds of
connections between this unit and instruments, mixers, and/or
components.
The remaining chapters show you how to operate the unit. Refer
to each as necessary.
For specific information regarding the individual effects and
parameters, refer to the separate “Effect Parameter Guide.” For
information regarding the preset memory, refer to the separate
“Preset Memory Catalog.”

Names and Functions of Parts
1U(Power switch)
Press this switch to turn the power on and off. Turning
on the power on recalls the last used memorized effect
and activates play mode automatically.
2 Effect algorithm list
Numbers and names of the 45 available effect
algorithms. 01~09 are 4ch algorithms, 10~36 are 2ch
algorithms, and 37~45 are Mono-Pair algorithms. (See
“Understanding Effect Algorithms and Program
Structures” on page 8 for details).
3 Input level indicators

signal input to the respective channel (1~4).
Green = –30 to -6 dB; Orange = –6 to –2 dB; Red = clip
(greater than –2 dB).
4 Display
Displays various information such as program
numbers, program names, effect numbers, effect
names, structures, parameter values, etc.
5 Fx TYPE (SEARCH) button

Effect algorithms
This unit contains three types of effect algorithms: 4ch, 2ch,
and Mono-Pair.
The 4 channel 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 2 ch 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 (m).
Parallel (/) program
FxA and FxB are completely independent.
Serial (m) 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

• 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
Hooking Up
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 MUTE (as shown on page 18).

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.
1Press Uto turn on the power.
After a few seconds, the play mode screen appears.
2Turn 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).
Basic Operations
Level indicators Display Rotary encoder
3Turn 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
