Professional

Digital

Multi-

Module.

With

this

purchase

you

have

come

into

possessionofoneofthe

most

efticient

processors

availableonthe

market

today,

capableofsolving

many

THE

Dynamic

sources

in

often

contain

eccessive

with

they

are

present.

Thanks

to the

compressoritis

the

inconveniences

of

overloading

and

thereby

obtaining

a

hemogeneous

result.

Furthermore,inthe

canbea

useful

instrumentinthe

of

special

especially

when

used

with

and

other

percussive

instruments.

LIMITER

In

wayasthe

Compressor,

the

Limiterisa

very

necessary

function

used

to

control

the

dynamicsofthe

The wayinwhichitworks

though

is

radically

different,asthe

Limiter

immediately

sets

the

dynamic

rangeofthe

input

signal

accordingtoa

previously

established

threshold.

ENHANCER

The

Enhancer,asits

name

suggests,

enhances

the

basic

frequenciesofthe

DENOISER

The

causes

of

background

noise

in

the

production

of

music

are

numerous;

pickups,

electronic

instruments,

microphones

etc.

The

Oenoiser

intelligently

analyses

the

removing

any

background

noise

without

altering
