How to use the HOMEASY M3R? 

 

To

 

use

 

easily

 

is

 

the

 

aim

 

of

 

HOMEASY

 

Series

 

gears.

 

So

 

it

 

is

 

quite

 

easy

 

to

 

use

 

and

 

operate

 

the

 

M3R.

 

Each

 

of

 

the

 

two

 

pre

amplifier

 

channels

 

has

 

its

 

own

 

input

 

and

 

output

 

and

 

variable

 

gain

 

control

 

individually.

 

 

Step

 

1

 

 

Simply

 

connect

 

a

 

signal

 

for

 

processing

 

to

 

one

 

of

 

the

 

XLR

 

balanced

 

inputs

 

on

 

the

 

front

 

of

 

the

 

M3R.

   

 

Step

 

2

   

Make

 

a

 

connection

 

from

 

the

 

corresponding

 

channel

 

output

 

on

 

the

 

front

 

of

 

the

 

M3R

 

to

 

your

 

desired

 

destination

 

(Mixer,

 

recorder,

 

etc).

 

 

Step

 

3

   

Adjust

 

the

 

variable

 

gain

 

control

 

to

 

the

 

desired

 

pre

amplified

 

level.

 

To

 

ensure

 

you

 

do

 

not

 

over

 

pre

amplify

 

your

 

signal

 

a

 

peak

 

clip

 

indicator

 

light

 

has

 

been

 

provided

 

on

 

the

 

front

 

panel

 

of

 

the

 

M3R

 

for

 

each

 

channel.

 

When

 

illuminated,

 

this

 

light

 

indicates

 

that

 

the

 

preamplifier

 

is

 

overloaded

 

and

 

that

 

distortion

 

will

 

occur.

 

Please

 

turn

 

down

 

the

 

variable

 

gain

 

control

 

for

 

the

 

currently

 

selected

 

channel

 

until

 

the

 

peak

 

clip

 

light

 

is

 

no

 

longer

 

illuminated.

 

Always

 

trust

 

your

 

ears;

 

the

 

Peak

 

LED

 

is

 

after

 

the

 

gain

 

control

 

so

 

you

 

could

 

actually

 

distort

 

the

 

input

 

with

 

a

 

very

 

high

 

level.

 

 
 

The

 

jack

 

to

 

connect

 

the

 

AC

 

power

 

adapter

 

in

 

the

 

packing

 

box.

 

Balanced

 

TRS

 

signal

 

outputs

 

of

 

Channel

 

A

 

&

 

B

 

to

 

connect

 

to

 

a

 

mixer,

 

audio

 

interface,

 

etc.

 

Each

 

channel

 

features

 

a

 

phantom

 

power

 

supply

 

for

 

enabling

 

the

 

supply

 

of

 

48V

 

through

 

the

 

XLR

 

input

 

connector

 

to

 

power

 

condenser

 

microphones.

 

Each

 

Switch

 

controls

 

one

 

channel

 

individually.
