DPS-F7

The

DPS-F7

Digital

Dynamic

Filter

Plus

is

a

new

signal

effector

using

innovations

in

signal

processing,

based

on

digital

filter

technology.

The

ten

types

of

algorithms

create

a

superior

sound

environment

considerably

exceeding

the

possibilities

available

through

conventional

effectors.

Quality-conscious

design

with

high-performance

A/D

and

D/A

converters

The

DPS-F7

converts

an

incoming

analog

signal

to

a

digital

signal

and

outputs

as

an

analog

signal

after

passing

it

through

various

effect

processes.

The

determining

factor

for

the

sound

quality

is

the

conversion

mechanism

which

incorporates

an18-bit

oversampling

stereo

A/D

converter

and

a

49.152

MHz

clock

advanced

pulse

D/A

converter,

which

together

results

in

highly

accurate

effects

with

little

deterioration

of

quality.

User-friendly

and

comfortable

operation

The

large

size

backlit

LCD

of

40

characters

by

2

lines

enables

smooth

operation

while

viewing

the

operating

condition

in

real

time.

The

on-line

manual

(in

English)

can

be

displayed

on

the

LCD

so

operation

instructions

are

immediately

available.

Abundant

preset

memories

The

DPS-F7,

in

its

preset

memory,

has

a

hundred

different

effects

created

by

musicians,

sound

mixers

and

acoustic

engineers

around

the

world

.

This

will

therefore

enable

you

to

select

and

replay

the

desired

effects

for

a

particular

purpose

immediately.

Creation

of

any

kind

of

sound

The

EDIT

function

allows

you

to

change

the

preset

effects

or

create

your

original

effects.

Aside

from

the

preset

memory

of

100

effects,

the

DPS-F7

also

has

a

user

memory

in

which

up

to

256

additional effects

can

be

saved,

giving

quick

access

to

an

even

greater

variety

of

effects.

Wide

range

of

effects

The

DPS-F7

is

equipped

with

an

effector

which

processes

_

and

output

signals,

a

vocoder

which

modulates

input

signals

to

one

channel

according

to

those

on

the

other

channel,

and

a

synthesizer

which

produces

sounds

by

MIDI

signals.

In

addition

to

these

three

fundamental

functions,

a

newly

developed

algorithm,

based

on

advanced

digital

filter

technology,

enables

you

easily

to

create

a

wide

range

of

effects

and

synthesizer

sounds.

It

is

also

easy

to

modify

the

effects,

since

the

effect

block

where

the

effects

are

modified

is

divided

into

sections,

under

which

you

can

easily

find

the

parameters

you

want

to

change.

Remote

control

A

remote

controller

(RM-DPS7)

is

also

available

separately.

Two

I/O

terminal

systems

The

DPS-F7

is

equipped

with

XLR

connectors

(balanced

type)

and

phone

jacks

through

which

you

can

connect

musical

instruments,

recording

equipment

and

PA

(public

address)

equipment.

Linkage

with

MIDI

equipment

Since

the

DPS-F7

is

equipped

with

MIDI

functions,

memory

numbers

of

this

unit

can

be

selected

with

program

change

signals

of

the

MIDI

device,

such

as

a

keyboard.

Moreover,

since

effect

level,

etc.

can

be

controlled

by

key

touch

and

control

change

signals,

the

unit

is

highly

effective

as

an

effector

for

digital

musical

instruments.

Automatic

performance

is

also

possible

by

controlling

with

computers

having

the

MIDI

interface,

or

with

a

MIDI

sequencer.
