GETTING

STARTED

QUICKLY

If

you're

like

most

new

owners,

you're

probably

in

a

hurry

to

plug

your

FX

mixer

in

and

use

it.

Here

are

some

brief

instructions

to

get

you

going

quickly.

With

the

mixer

unplugged,

turn

the

unit

off

and

complete

the

following

procedures:

1)

CONNECTING

AC

POWER

TO

YOUR

MIXER

•

Check

and

change

if

necessary

the

rear

AC

Line

Voltage

Switch

to

the

proper

voltage.

Change

the

fuse

if

necessary

(listed

on

rear

panel)

it

using

240V

AC.

•

Use

only

a

grounded

(3

prong)

power

outlet

to

prevent

a

shock

hazard.

This

gives

the

quietest

grounding

for

your

mixer.

2a)

CONNECTING

SPEAKERS

(Powered

Models

Only)

-

Use

the

four

1/4"

speaker

jacks

on

the

rear

panel

(two

jacks

each

for

the

Right

and

Left

channels

which

are

controlled

by

the

2

Track

"R

&

L"

faders).

Use

only

Heavy

-Duty

speaker

cables

(16

ga

for

50'.14

ga

for

100').

NOTE:

Do

not

run

your

speakers

through

microphone

wire

or

multi

-conductor

microphone

junction

boxes

or

"snakes"

as

sometimes

referred

to.

This

wire

is

normally

a

very

light

20

gauge

wire

causing

a

substantial

fuss

of

power

through

the

cable

for

less

power

to

your

speakers.

All

speaker

wires

must

be

non-shieldert

to

prevent

the

power

amplifier

from

oscillating

at

high

frequencies.

2b)

The

"PROTECT"

LED

—Detects

incorrect

speaker

impedance

•

If

the

speaker

impedance

is

lower

than

4O

(per

channel)

the

"Protect"

LED

will

display

and

engage

the

protect

relay

(this

will

happen

only when

playing

very

loud).

This

relay

will

disconnect

the

speakers

from

the

power

amp

leaving

the

mixer

on.

To

reset

the

"PROTECT"

circuit,

simply

turn

the

mixer

off

and

then

on

again.

To

prevent

this

from

happening

again,

be

sure

your

total

speaker

impedance

to

each

power

amp

is

not

lower

than

4O.

This

protect

circuit

also

engages

it

the

mixer

becomes

too

hot

to

operate.

However,

this

is

a

rare

situation

unless

the

fan

is

blocked.

3)

CONNECTING

INPUTS

TO

YOUR

MIXER

-

For

low

level

balanced

devices

such

as

microphones,

plug

into

the

balanced

"MIC"

XLR

input

at

the

rear

of

the

mixer.

Use

a

3

conductor

shielded

cable.

-

For

high

output

level

devices

such

as

Tape

Recorders,

CD's,

Keyboards

and

Wireless

mic

receivers.

plug

info

the

"LINE"

1/4"

input

jacks

on

the

rear

panel.

Use

a

2

conductor

shielded

cable.

4)

TURNING

YOUR

MIXER

ON

•

Adjust

all

faders

and

level

controls

of

your

mixer

to

the

off

position.

•

Adjust

all

"EQ"

tone

controls

—Hi,

Hi

Mid,

Mid

and

Bass

and

the

9

Band

Graphic

EQ

to

their

center

position.

•

Adjust

all

the

Channel

"PAN"

Assign

controls

to

their

center

position.

•

Turn

the

mixer

on

by

the

rear

panel

power

switch

and

watch

for

the

meter

lamps

to

come

on.

Your

mixer

is

now

on

and

ready

to

operate.

•

Be

sure

to

"assign"

the

"L

-R"

switches

on

the

channels

(or

the

1-2.

2-4

sub

group

switches).

Now

raise

the

"Channel"

and

"2

Track"

Faders

(Sub

Group

faders

it

assigned

)

and

you

should

have

signal

coming

out

the

mixer.

Things

To

Know

la)

"GAIN"

INPUT

LEVEL

SETTINGS

(Channel)

For

the

lowest

"Channel"

noise,

set

the

MIC

or

LINE

"Gain"

controls

(above

the

channel

fader)

up

to

the

highest

cossibie

setting

—just

before

the

"Peak"

LED

flashes

(It's

OK

if

it

flashes

occasionally).

If

these

levels

are

not

set

up

to

this

Point

your

noise

levels

will

be

higher

than

normal

.

lb)

CHANNEL

FADER

LEVEL

SETTINGS

(Channel)

The

large

slider

at

the

bottom

of

each

channel

is

referred

to

as

the

"Fader".

This

control

should

always

be

set

around

the

213

position

(-5

to

0)

on

the

fader

scale

for

high

volume.

If

they

are

set

lower,

you

will

have

more

system

noise

because

you

are

running

the

master

2

-Track

faders

higher

than

you

should.

1c)

SUB

GROUP

AND

2

TRACK

FADER

LEVEL

SETTINGS

(Master

Section)

For

the

lowest

noise

,

these

controls

should

be

run

lower

than

the

channel

faders

(from

-20

to

0)

However,

be

careful

that

these

controls

are

not

set

too

low

because

distortion

can

result

from

any

channel

that

is

set

too

high.

NOTE:

For

the

lowest

noise

performance

for

any

mixing

console,

a

good

rule

of

the

thumb

is:

a)

Run

the

input

"Gain—Mic

or

Line"

to

their

maximum

—just

before

the

"Peak"

LED

flashes.

b)

Run

the

"Channel'

fader

around

the

2/3

position.

c)

Run

the

"Sub

Group

and

2

Track

Faders"

around

the

1/2

position

or

lower.

d)

The

numbers

on

the

Faders

controls

are

shown

in

dB

levels

with

the

"0"

representing

the

normal.

"

pass

thru"

gain

—no

attenuation

or

boost

from

from

that

pre

amp

section.

2)

INTERNAL

REVERB

SYSTEM

For

the

best

results

when

using

the

internal

reverb

system

you

should

set

the

EFF6

send

levels

eign

and

set

€he

revere

return

(MONO

D)

on

the

system

master

strip

for

the

desired

amount

of

reverb.

3)

PowerTrack'

m

and

"CLIP"

LED's

(Powered

Models

Only)

A

switch

at

the

rear

panel

allows

the

PoworTracit

TM

compressor

to

be

switched

en

or

off.

The

purpose

of

this

feature

is

to

delay

the

onset

of

power

amp

clipping

(distortion

—which

is

detected

by

the

"Clip"

LED's

above

the

MONO

level

control)

.

We

recommend

that

you

leave

this

feature

on

as

it

will

give

more

useable

power

NOTE:

It

is

normal

for

the

VU

meters

to

peg

to

the

far

right

before

the

power

oinp

"Clip"

liyhts

come

on.

This

does

not

constitute

abuse

of

the

meters
