The

Main

Outputs

1)

The

2

TRACK

Master

Faders

This

stereo

fader

pair

sets

the

overall

level

at

the

two

-track

outputs

of

the

mixer.

The

two

-track

outputs

are

available

at

the

rear

of

the

mixer

on

a

pair

of

balanced

XLR

connectors

as

well

as

a

pair

of

RCA

phono

jacks.

The

balanced

outputs

are

recommended

for

long

cable

runs.

For

short

cable

runs

(typical

of

recording

situations)

the

RCA

phono

outputs

are

fine.

2)

The

MONO

Master

Level

Control

The

MONO

MASTER

control

sets

the

level

at

the

mono

output

of

the

mixer

(one

balanced

XLR

connector).

The

mono

signal

is

the

sum

of

the

left

and

right

outputs

so

the

2

TRACK

faders

must

be

raised

in

order

to

have

a

mono

output

signal.

3)

The

GRAPHIC

EQUALIZERS

Each

FX44

mixer

is

provided

with

two

nine

band

graphic

equalizers.

Each

graphic

EQ

has

a

bypass

switch

and

LED

status

indicator

located

below

it.

The

LED

is

illuminated

when

the

graphic

EQ

is

switched

into

the

signal

path.

The

graphic

EQ's

are

dedicated

to

the

two

-track

outputs

of

the

mixer.

Note

on

Powered

Models:

The

Graphic

EQ's

(as

well

as

the

power

amplifiers)

can

be

switched

from

the

2

TRACK

outputs

to

the

MONO

and

MON

1

outputs

for

convenient

mono

PA

operation.

The

Stereo/Mono

switch

is

located

on

the

rear

of

the

mixer

above

the

speaker

jacks.

You

should

find

the

graphic

EQ

especially

useful

for

controlling

feedback

in

the

monitor

system.

Note

that

the

graphic

EQ's

follow

the

amp

interrupt

jacks

so

that

any

signal

patched

into

the

amp

input

will

be

processed

through

the

corresponding

graphic

EQ.

The

9

band

Graphic

Equalizers

in

the

FX44

mixers

provides

a

wide

degree

of

tonal

flexibility.

To

properly

use

the

Graphic

EQ

(equalizer),

set

all

sliders

to

their

center

position.

With

the

sliders

at

this

position,

there

is

no

effect

on

the

audio

signal.

When

you

raise

the

slider

above

the

center

position,

you

boost

levels

in

a

narrow

frequency

band.

If

you

lower

the

slider

below

the

center,

you

are

subtracting

levels.

When

using

these

sliders,

think

of

them

as

volume

controls

that

can

add

or

subtract

tones

in

narrow

bands.

Frequency:

The

63

Hz

slider

Is

used

for

deep

sub

bass

level

adjustments,

the

125

Hz

is

for

higher

bass

adjustments,

the

250,500

and

1K

Hz

is

for

mid

and

higher

mid

tone

adjustments,

the

2K

and

4K

Hz

is

for

mid

treble

adjustments,

and

the

8K

and

16K

Hz

sliders

add

to

the

very

high

treble

notes.

Adjusting:

It

is

recommended

that

all

sliders

are

set

in

their

center

position

before

equalizing

your

tone.

Typically

low

frequency

feedback

is

in

the

125

and

250

Hz

range

while

high

feedback

is

in

the

2k

and

4k

Hz

range.

Occasionally

you

may

have

to

turn

one

frequency

(slider)

off

to

-12dB

to

help

stop

feedback.

But

you

should

never

turn

the

adjacent

sliders

off.

Instead,

set

the

adjacent

sliders

to

-6d6

to

form

a

gentle

negative

curve.

Likewise,

if you

need

more

deep

bass,

boost

the

63

Hz

by

10

dB

and

the

125Hz

by

5

dB.

Or.

if

you

need

more

treble.

boost

the

8k

by

6

dB

and

the

16k

Hz

by

4

dB.

Note

—

there

is

not

much

signal

at

16k

so

you

may

not

hear

any

difference

except

for

added

noise.

if

you

raise

or

lower

all

sliders

at

the

same

time,

the

EQ

will

act

like

a

volume

control

because

you

are

affecting

all

frequencies.

Be

careful

with

your

adjustments,

because

you

are

affecting

the

overall

sound.

If

you

are

not

familiar

with

the

operation

of

a

graphic

EQ

then

one

way

to

get

familiar

with

the

equalizer

is

to

experiment

with

the

sounds

of

the

different

bands.

Run

some

prerecorded

music

through

the

mixer

and,

with

the

EQ's

switched

in,

set

each

of

the

bands

at

"0".

Pull

the

right

2

TRACK

fader

all

the

way

down

so

that

you

are

listening

to

only

the

left

channel.

Then

boost

and

cut

each

band

of

the

left

(top)

EQ

one

at

a

time

to

become

familiar

with

the

way

it

affects

the

sound.

Then

experiment

with

the

overall

sound

of

all

the

bands

of

the

equalizer

until

you

learn

to

recognize

the

sound

of

each

band

The

graphic

EQ's

are

mainly

used

to

"equalize"

the

response

of

the

main

speakers

to

provide

the

best

sound

for

a

given

room.

You

are

able

to

switch

the

graphics

in

or

out

of

your

main

mix

for

an

instantaneous

evaluation

of

how

they

are

affecting

your

main

speakers

by

pressing

the

IN/OUT

switch

located

just

below

the

equalizers.
