HOMEASY M3R 2-Channel Microphone Preamp 

 

Main Description 
 

If

 

you

 

are

 

not

 

a

 

professional

 

music

 

man,

 

or

 

you

 

don’t

 

wish

 

to

 

have

 

a

 

big

 

2U

rack

 

gear

 

to

 

use

 

in

 

the

 

pro

 

audio

 

cabinet,

 

HOMEASY

 

M3R

 

would

 

be

 

your

 

best

 

choice

 

indeed,

 

as

 

it

 

is

 

a

 

true

 

desktop

 

pro

 

audio

 

gear.

 

Although

 

smaller

 

and

 

cheaper

 

than

 

the

 

other

 

standard

 

2

CH

 

mic

 

preamps

 

from

 

AC

AUDIO,

 

such

 

as

 

G32

 

and

 

G52,

 

M3R

 

would

 

be

 

a

 

most

 

suitable

 

pre

 

for

 

quasi

professional

 

and

 

consumer

 

users

 

at

 

limited

 

cost,

 

which

 

is

 

completely

 

able

 

to

 

provide

 

pure

 

pre

amplifying

 

performance.

 

M3R

 

provides

 

independent

 

phantom

 

power

 

for

 

every

 

channel,

 

as

 

well

 

as

 

the

 

gain

 

control

 

from

  ‐

20dB

 

to

 

+40dB.

 

The

 

completely

 

metallic

 

cover

 

and

 

panels

 

give

 

wonderful

 

performance

 

against

 

external

 

interference.

 

Furthermore,

 

M3R

 

adopts

 

NE5532

 

high

class

 

transistor

 

operational

 

amplifier

 

module,

 

which

 

has

 

higher

 

capability

 

than

 

4558

 

to

 

acquire

 

more

 

pure,

 

clear

 

pre

amplifying.

 

In

 

one

 

word,

 

HOMEASY

 

M3R

 

would

 

be

 

your

 

most

 

cost

effective

 

choice

 

for

 

preamp

 

gear

 

at

 

this

 

pricing

 

level.
