Thank

you

for

choosing

a FOCUS

mixing console.

We

are sure that it will

provide

you

with

many

years

of reliable

service.

FOCUS

mixers

are available

with 8,12,16

and24

channels. Each channel

offers Mic

and Line Inputs,

an lrsert

poin!

Gain control

with

peak

LED,

3 bands

of Equalisation,

3

Auxiliary

sends, Pan

control,

Cue switch and a master

slider.

The

output

section

consists

ofleft and Right

master

sliders, balanced

and unbalanced

outputs,

2 retums,

headphone

socket

and

phantom

power

switches.

The

use ofthese

controls

will be discussed

throughout

this manual.

A correctly

set up mixer is

the key

to a

good,

clear

sound. This

section is

designed

to

help

the

you

with

an

initial

set up of all

the

levels

and

controls.

Connect

the mixer

to mains

power

and

switch

on. A red LED

on the far

right

hand

side

will indicate

power.

You

will need

two microphone

leads

(3 pin

XLR)

or two

guitar

leads

(l/4"

jacks)

to

connect the mixer

to

your

amplifier.

These leads run

from

the

GRP/OUTPUT sockets

just

left

of the

power

switch

to the Left

and Right

(or

A & B) inputs

of

your

amplifier.

After checking

that

the master faders

are

hrned down,

switch on

your power

anplifier.

The next

step is

to

plug

all

your

inputs into

the mixer.

Microphones

should

be

plugged

into

the 3

pin

)(LR

socket, while

line inputs

such as

cD

players,

tape decks, keyboards

etc,

should

be

plugged

into

the l/4" line

socket.

A very important

section of

any

mixer

is

the

gain

contol,

which is

the first knob

on

each channel. The

idea

is to

set this conhol as hi&

as

possible

without

the

Peak

LED

coming

on. Adjust

each charmel

individually

while the mics

or inputs

are being used

in

their normal

way.

The

cenfre

position

is

a

good

starting

point.

The

next

three

controls are for Equalization.

tIF

stands for high frequency,

MID for

Middle

frequency,

and LOW

for low frequency.

These

confiols

allow

you

to tailor

the sound

of each

input.

The

starting

point

for

these confrols is

in the

centre

position.

of Equalization

is

to improve

the

sound,

so

feel

free

to experiment.

The AIIX

l, A{IX 2

and AtX

3

confiols

are only needed

when

using

effects

(reverb,

digital

delay

etc),

or when

using a foldback

(monitor)

system. Please

see

the

separate

section

on

The

button is

used in

conjunction

with

the headphone

socket. When

the

CUE

button

is

on, it

allows

you

to monitor

inputs

through

the headphones.

When

using

you

also

you

can monitor

the

entire mix, which

is

basically

the

fed

to

your

amplifiers.

The

The

slider at

the bottom

ofeach

channel

confiols how

much

to

section. It

is

simply a volume

control for

each

channel.

To

get

any

sound from

your

mixer,

both the

channel

slider and

the master

slider need

to

be

tumed

up.

The

above information

is

all that

you

need

to known

to

set up and

operate

a basic

system.

Practice

and hands-on

experience

will make

you

an expert.

The

next

stage

of this

booklet

deals with the

more

advanced

features

of

the mixer.

Auxiliaries

are

known

as sends

because they

are used

to send

a signal

out

ofthe mixer.

You will

notice

that

each channel

has

3 auxiliaries,

and

that there

are 3 master

Auxiliaries

on

the far

right

hand

side of

the mixer.

There

are also

three l/4"

Atxiliary

output

sockets.

Auxiliaries

are normally

used for foldback

and/or effects,

but can

also

be used

to

recording

or

to feed

a

hearing

loop

arnplifier.

Foldback:

This

term

refers

to

a

monitoring

system

usually comprising

of another

amplifier

and

onstage

speakers. Foldback

is

used so that

performers

can hear

themselves

while

on stage.

A foldback (monitod

system

would norrnally

be connected

to AIIX

l,

because

this is

pre-fader,

which

means

that the

channel

slider has no

effect

on the

aux output.

To connect

a

foldback

system,

run a lead from the

AIIX 1

output to the

line input

of

you power

amplifier. As a starting

point

set

the Aux I master

in

the centre

position

and slowly

raise the Aux I

control on the channel that

you

are using.

Adjust

the

Aux I for

each

channel

that is required for foldback

so that

you

have

a suitable

mix

ofall the channels

in

the foldback

speakers.

Effects:

AI-IX 2

and 3 are

post

fader

which

means

that the

position

of the channel slider affects

the amount

of

level

being

sent to these auxiliaries. Aux 2 and

3

would

normally

be used for

effects.

When

using effects, the

Auxiliary

ou@ut sends the signal out of

the mixer,

but the effect

has to

be

returned

and combined

with

the original sigrral.

To connect an effect, run

a

lead from

the Aux 2

or

3

output to the

input

of

yow

effects units.

The

effects unit

will have

one

or

two

outputs

(2

for

stereo), which need to be connected to the returns

of

the mixer. T\e Focus

mixers have

two retum inputs which are

positioned

just

below the master

outputs. The

Volume and Pan contols for

the

returns are below that master LEDs.

The return volume tells the mixer how much of the sigral with effects

is

being

rehrmed.

The retum Pan contol allows

you

to decide if the effect is

going

to be mixed with

both

the left and right outputs or anywhere in between.

When

returning

a stereo effect, run the left effect output into Return I and Pan

firlly

left,

and return

the

right

effect output into Return

2

and

Pan

fuflV right.

This will maintain the

stereo

image that is created from

the

effects unit.

Another method

of

retuming

effects

is

to use the

line input

of

a

spare channel. This

allows

you

to EQ the retum and control the

retum level

from a slider.

If

you

use this

method,

please

make

sure that the

Aux that

you

are retuming is

completely tumed down on tlte channel, otherwise

you

will experience

some loud

squeals.

Foczs mixers have

an monitor output

which

sends

the entire mix

post

faders to the Left

and Right 1/4" monitor outputs.

The MON contol which is

situated

just

above the

headphone

volume

knob

controls the

amormt of

level

going

out the monitor outputs.

The

monitor

outputs would

normally be

used to

feed

another

audio source

such as

a a

house

PA

system,

or to nrn to a tape recorder.

Please note

that the monitor level

is varied

by

both the charurel

and master

sliders.

For foldback,

it is

best

to use the ALIX I

send, urs this

provides

a control on

each

channel, and

allows

you

to set the levels

pre-fader.

Please

see the Auxiliaries

section.

Phantom

Power is needed

when

using electret/condenser

microphones.

These

type

of

mics

(usually

gooseneck

or tie mics) require

a voltage from

the mixer

to work.

With

the Focus mixers,

you

can have

phantom power

on either the first half

or second

half

of

the

mixer,

or on every

channel.

There

are two

phantom

power

switches

just

below the AIIX

outs. The

green

LED

indicates

when

phantom

power

is

on.

Please

note

that

phantom

power

cannot

be used with unbalanced

microphone

To

maintain

the effect

of stereo,

you

will

need

to use two

channels of

the

mixer,

one

channel for left

and

one

for

right.

Set the channels up identically

except for the

Pan controls.

One

pan

should be set

completely left

and the other

completely right.

If

you

are

not

using

effects,

you

can use

the

retums

as inputs.

This will not

grve

you

atry

equalisation,

but

it

will allows

you

to confol the

volume and

pan

controls.

Every

channel

of the Focus mixers has

a l/4" insert

socket. An insert

point

allows

you

to send

your

sigral

out ofthe mixer

and

return

it through

the same

socket. It can

also be used

as a direct

channel output.

The

insert

point

is

normally

used to

place processors

(Compressors,

Equalizers,

Noise

Gates etc)

across a signal

channel. It

therefore

requires

a

3

conductor

(stereo)

jack.
