AMP

SET

UP

-

Do

Not

Turn

On

Yet!

The

DCA/DCM

series

amplifiers

are

designed

For

"table

top"

or

"rack

mounting."

The

Four

rubber

Feet

may

be

removed

if

amps

are

to

be

stacked.

When

"rack

mounting"

the

amp,

be

sure

to

allow

For

sufficient

air

flow.

The

rack

must

have

an

open

back

to

allow

for

the

normal

Flow

of

hot

air

up

and

away

From

,the

rack.

Make

all

connections

to

the

amplifier

(input

and

output)

prior

to

turning

on

the

unit.

Be

sure

all

cords

are

well

maintained

and

of

the

proper

type

for

the

input

and

output

connections

to

the

amp.

(All

input

connections

should

be

shielded

cable,

and

all

output

connections

should

be

non

-shielded

1SAWG

guage

wire

or

greater).

POWERING

UP

THE

AMPLIFIER

After

all

connections

have

been

made

to

the

amp,

be

sure

all

the

gain

controls

are

fully

counter

clockwise

(off)

.

Turn

on

all

the

pre

-amp

(mixer)

equipment

and

then

depress

the

power

switch

to

apply

power

to

the

amp.

Note:

Be

sure

the

amplifier

is

plugged

into

a

properly

rated

A.C.

source.

(120U

regulated

power

supplu

source)

.

Note:

When

the

power

switch

is

depressed

the

light

in

the

switch

will

come

on

to

indicate

the

amp

is

operational.

Sometimes

there

is

a

slight

delay

in

the

illumination

of

light

within

the

switch,

due

to

the

characteristics

of

neon

lights.

This

is

normal

&

does

not

affect

normal

operation

of

the

amp.

IF

the

light

does

not

illuminate,

check

to

be

sure

the

amplifier

is

plugged

into

a

live

power

outlet

or

source.

With

all

the

pre

-amp

(mixer)

controls

Fullu

off,

turn

up

the

the

gain

controls

to

approximately

the

12

o'clock

position

(half

wag

up)

.

There

should

be

no

audible

hum

or

excessive

hiss.

IF

you

do

hear

hum

or

excessive

hiss,

check

your

input

and

output

cables

as

well

as

connections

&

gains

of

the

pre

-amp

equipment

driving

your

power

amp.

New

advance

the

pre

-amplifier

(mixer)

gain

until

the

desired

volume

is

attained.

Try

to

keep

the

pre

-amp

(mixer)

controls

at

a

minimum

setting

with

the

power

amp

controls

at

a

relatively

higher

setting.

This

will

help

assure

that

the

cleanest

possible

signal

is

driving

the

power

amp.

And,

it

helps

assure

the

best

signal-to-noise

performance

From

your

system.
